The digestive. respiratory and cardiovascular systems all work together to supply energy for the tissues and variety meats of the organic structure. The function of the respiratory is to go through O into the blood. The respiratory system oxygenates blood. Oxygen so easy diffuses from the air sac in the lung through the epithelial walls into the blood stream. If your organic structure were deprived of O. cells would get down to decease. The function of the cardiovascular system is to go around blood around the organic structure through the pneumonic circuit which takes blood takes up O in the lungs and the systemic circuit where oxygenated blood is distributed to organic structure tissues. Then the cardiovascular system supplies oxygenated blood to the parts that make up all three systems. leting respiration to go on and the cells. and variety meats to work.

The function of the digestive system is to interrupt down nutrient from complex chemicals into simple chemicals that can be used as fuel. It does this utilizing enzymes such as peptidases. amylases and lipase which leaves the organic structure with aminic acids. glucose. glycerin and fatty acids which can be used around the organic structure. The digestive system interruptions down nutrient. foods from the nutrient that organic structure needs diffuses easy through epithelial walls of the villi into capillaries and base on ballss in the blood stream to the variety meats and cells that are in need energy. The terminal merchandises. C dioxide and H2O or removed from the organic structure by the respiratory and nephritic system.

Describe the 6 signifiers of energy and explicate how the organic structure uses each signifier. Specify what is meant by the metamorphosis and explicate the two types. ( M1 ) 1. Chemical- Generally chemical energy is a signifier of possible energy and is controlled by things such as nutrient. fuels and batteries. Energy comes from this because of chemical reactions. Energy is stored in the nutrient. when this is so digested the nutrient is broken down and the energy is passed onto the cells of the organic structure. The procedure of interrupting down and utilizing the nutrient by our cells is called respiration. During respiration. the chemical energy is converted to into other types of energy such as heat and kinetic energy that the organic structure can so utilize. 2. Kinetic- All traveling things have kinetic energy. This energy is created by motion or gesture. Heavy objects will travel faster and hold more kinetic energy than lighter objects. The organic structure has kinetic energy if traveling. If walking or running the organic structure will hold kinetic energy. the energy will assist you take the following measure.

3. Thermal- This energy comes from heat. The hotter something is the faster the atoms move about hence the more thermic energy there is. The organic structure converts stored possible energy in the nutrient you eat into thermic energy which keeps the organic structure at 37. 5°C. 4. Sound- Sound is quivers which travel in moving ridges and can be heard through different mediums. Sound is used by the organic structure to be able to hear. The outer ear country is at that place to roll up sound quivers. This sound is so amplified and passed from the outer ear to the ear membranophone. From here audile nervousnesss pick up on things such as pitch and volume.

5. Electrical- Nerve urges are the body’s electricity. The nervous system is a web of cells called nerve cells which transport information in the signifier of electrical signals around the organic structure. 6. Light- Light Energy is the motion of photons. The Sun is a major beginning of visible radiation. Light is needed to keep a normal map of the organic structure. Light and darkness are needed to command the production of melatonin. 5-hydroxytryptamine and endocrines that the organic structure needs. Sunlight is needed by the hypothalamus. pineal and other secretory organs of the encephalon.

Metamorphosis is a group of chemical reactions that take topographic point in the cells of the organic structure. The metamorphosis changes the fuel in the nutrient we eat into the energy needed by the organic structure. for illustration circuiting blood. external respiration. traveling and turning. Chemical reactions that occur are specific to certain proteins in the organic structure. Metabolic reactions are invariably maintaining the cells healthy and working. Thyroxine a endocrine produced by the thyroid secretory organ plays a cardinal function in finding how fast or decelerate the chemical reactions of metamorphosis proceed in a person’s organic structure. When nutrient is eaten. digestive enzymes break proteins down into aminic acids. fats into fatty acids and glycerin. and carbohydrates into glucose or other simple sugars. Amino acids. glucose and fatty acids are all signifiers of energy.

These are so absorbed by the blood and transported around the organic structure through venas and arterias to the cells. Amino acids are used by the organic structure for doing new enzymes and some endocrines. fix and growing. Amino acids can non be stored so they are broken down by the liver and excreted by the kidneys as piss. Glucose is broken down by the internal respiration to let go of energy. Excess glucose is stored in the liver until it is used or converted into fat that is so stored under the tegument. Glycerol and fatty acids can be used to reconvert stored fat into energy.

The two types of metamorphosis

Anabolism- ( Constructive ) This reaction makes simple chemicals into complex chemicals. This type of is for edifice and hive awaying energy or fat. It helps the growing of new cells and the fixs and maintains organic structure tissues. This type keeps energy in instance the organic structure needs it in the hereafter. Catabolism- ( Destructive ) This reaction breaks downs complex chemicals into simple chemicals. In this procedure cells break down stored saccharides and fats and let go of them as energy in the organic structure. This procedure provides fuel for constructive metabolism. When the complex chemicals are broken down into simple 1s the waste merchandises are removed from the organic structure through the tegument. kidneys and lungs.

Describe how the systems work together. Discourse how stuffs move into the cardiovascular system from the air sac and the villi. Explain how their construction makes it easier to let this motion to go on. ( D1 ) The fuel significance saccharides or fats enter the organic structure through the oral cavity ; this is the start of the procedure through the digestive system. The digestive system interruptions down complex nutrient chemicals into simple chemicals that can be absorbed and used by the organic structure. It does this utilizing enzymes. these are substances that increase the rate of chemical reactions therefore can back up the digestive system by interrupting down nutrient all the manner through its journey. Enzymes are specific to certain substrates. Merely molecules with the right form can suit into the enzyme. This is sometimes described as like a lock and key. merely one type of enzyme can rush up a specific reaction. For illustration nutrients such as meat. eggs and nuts are all proteins.

Proteases act on proteins. interrupting them down into aminic acids and peptides. Amylases work on amylum substrates ; these are from saccharides such as staff of life. rice and pasta. interrupting them down into glucose. Finally lipases alteration lipoids to fatty acids and glycerin. which comes from fats such as dairy. ruddy meat and oils. The terminal merchandise of aminic acids. glucose. fatty acids and glycerin would hold been broken down in different locations such as the oral cavity. tummy and eventually duodenum. Once the fuel has been broken down into simple chemicals it will go through through the ileum. This is the balance of the little bowel and is a major portion of soaking up. The ileum is covered in projections called villi which increase the surface country of bowel. Each villus has microvilli that increase the surface country even further to do more room for diffusion to take topographic point. Inside each villus are lacteals these absorb fat and are portion of the lymphatic system.

Around the villi there are many capillaries. Amino acids and simple fatty acids diffuse across the surface of the villi into the rich blood supply of the capillaries. This can go on because the interior wall of the little bowel are really thin and semi-permeable. with a big surface country. This allows soaking up to go on rapidly and expeditiously. Once in the blood stream it will be carried to variety meats and populating cells which are in demand via the cardiovascular system. Peptides and aminic acids will be used to do enzymes and let the metamorphosis to run. Glucose is used as a fuel to supply the organic structure with energy. Fat is stored under the tegument until glycerin reconverts the stored fats into energy. The following portion of the energy equation is oxygen. Oxygen is brought into the organic structure via the respiratory system. The respiratory system has three chief occupations these are take a breathing. gas exchange and blood conveyance. First oxygen gets into the organic structure by take a breathing.

Breathing is indispensable because cells in the organic structure necessitate O. The lungs are ventilated by take a breathing ; they inflate and deflate in the chest pit when you breathe in and out. The stop contracts and flattens which makes the chest pit push air into the lungs. Air enters the thorax via the nose and oral cavity by the clip it reaches the pharynx most of the unwanted atoms can be removed such as dust. C and pathogens. The windpipe is located at the start of the dorsum of the pharynx and divides into two bronchial tube. one for each lung. Inside each lung there are many bronchioles. the bronchioles end in air pouch called alveoli. Alveoli are bantam and are bunched together in bunchs to organize alveolar pouch.

The walls of the air sac are made out of really thin simple squamous epithelial tissue. Around these pouch. on the surface. there are many capillaries that carry blood ; the walls of these capillaries are besides made from really thin simple squamous epithelial tissue. This means that air that enters the air sac during external respiration is merely separated from the blood by two really thin walls. Epithelium is semi-permeable which means that gases can easy go through through. due to the procedure of treatment. both of these walls and that is how exchange occurs. Diffusion is the motion of chemicals from a high concentration to an country of low concentration. Gas exchange is when O passes out of the air into the blood. and C dioxide passes out of the blood into the air in the air sac.

The bosom pumps blood around the organic structure through venas. arterias and capillaries. While making this it gives populating cells O and at the same clip removes C dioxide and H2O. The cardiovascular system therefore gives you the merchandises of the energy equation. The merchandise C dioxide. which isn’t used in the organic structure. is removed as you exhale because of the gas exchange which happens in the lungs. The merchandise H2O is either used by the organic structure or removed by the nephritic system as urine or as perspiration in the chilling vaporization procedure.

This leaves the last portion of the equation. the merchandise energy. which helps the organic structure map. To reason the respiration. digestive and cardiovascular systems all work together to supply energy for the tissues and variety meats of the organic structure. The respiratory system oxygenates blood. Oxygen so easy diffuses from the air sac through the epithelial walls into the blood stream. Then the cardiovascular system supplies oxygenated blood to the parts that make up all three systems. leting respiration to go on and the cells. and variety meats to work. The digestive system interruptions down nutrient. foods from the nutrient that organic structure needs diffuses easy through epithelial walls of the villi into capillaries and base on ballss in the blood stream to the variety meats and cells that are in need energy. This energy allows for respiration to happen.
