    1. 1. Report of : Roma Oclares
    2. 2. --is a life process common to both plants and animals. -- In this Process, there is an exchange and carbon dioxide. -- In our body, oxygen continuously supplied to your body cell and is transported through your bloodstream.
    3. 3. -- is then used to oxidize or “burn” food materials in every living cell. -- After cellular breakdown of food, carbon dioxide is released by cell. -- This gaseous waste is again picked up by your blood and is expelled from your body system. 1. Oxidation of food by living cell. 2. Transport of oxygen to the cells and the removal of carbon dioxide from lungs. 3. Exchange of gases between your blood and lungs. 4. The breathing process.
    4. 4. Your Respiratory System allows the exchange of gases to occur with two important phases involves : EXTERNAL RESPIRATION and INTERNAL RESPIRATION
    5. 5. External respiration -- is the exchange gases between the atmosphere and the blood. This involves the lungs.
    6. 6. Internal respiration -- is the exchange of gases between the blood and the body tissues. It occurs in every living cell.
    7. 7. -- In External respiration, oxygen from the air goes into your lungs through the respiration tract. In your lung capillaries, oxygen joins your blood. At this point, the level of oxygen is higher in the alveoli of your lungs.
    8. 8. The blood that leaves your lungs is called oxygenated blood. The blood entering your lungs is said to be deoxygenated blood.
    9. 9. ♫ is a mechanical process that helps get air in and out of the lungs. ♫ it consist of two stages :
    10. 10. ♪ Life depends on breathing because the body cells need oxygen. ♪ Oxygen is one of the mixtures of gases found in air ♪ During inspiration, you breath in or inhale to bring fresh supply of air into your lungs. ♪ During expiration, you breathe out or exhale to get rid carbon dioxide or waste gases not needed by your body. ♪ They are then expelled to relieve your body cells of wastes.
    11. 11. Infants – 30 to 40 times a minute. Six years old – about to slows down 22 times a minute. Your age until your about 25 – further slowed down about 16 to 18 times a minute. - An exception when you are an athlete or when you engage a hard work. - Your Breathing rate such cases will be higher.
    12. 12. a. Air enters to your nose. The nostril serve as entrance to your nasal cavities. They are a pair of passage separated by a bony septum. b. Inside the right and left nasal cavities are coarse hairs that filter the air and trap any microorganism or dust
    13. 13. T H E L U N G S ∞ Your Lungs occupy twin cavities, one at each side of the chest. ∞ They separated by your heart, blood vessels, and your esophagus. ∞ Each of Lungs is large enough to fill the pleural division of the thoracic cavity. ∞It is cone-shaped with its base pointing downward, resting on the diaphragm, or sheet of muscle, below. ∞The top, or apices, on the other hand, bulge upward.
    14. 14. Your left lung is slightly smaller than your right. It has two main division or lobes while the right lung has three.
    15. 15. Your lungs are spongy and are covered by a double pleural membrane which secretes mucus. The mucus acts as a lubricant, permitting the lungs to move freely in the chest during breathing. Your lungs fit into a box-like space. At the
    16. 16. is a process by which waste materials from the oxidation of food cell in cell metabolism are removed from living cells. Carbohydrates breakdown produce carbon dioxide and water as its waste products. These are removed from the body through the lungs during expiration
    17. 17. Other excretory organ which you have already studied are you liver which forms urea and biles.
    18. 18. -- Your skin which excretes water, salts and urea in the form of sweat. -- Your Large Intestine, an organ that removes feces.
    19. 19. -- is a nitrogenous waste substances found chiefly in the urine mammals. -- another nitrogenous waste products of cell activity, is insoluble and is mainly found among land animals.
    20. 20. The excretory process --- Its parts and function  lower forms of animals, especially one-celled organisms, expel their cells waste products directly into their environment. In some protozoan's, excretory processes occur almost similarly. Euglena expels food materials through the cell membrane. Amoeba retains undigested food particles in a vacuole and later passes them out at any point in its ccell membrane
