CONCEPT MAP: RESPIRATORY AND CIRCULATORY SYSTEM - Coggle Diagram

- - - - Aerobic respiration: is a chemical reaction to have ATP, it happens in all our body.
        Happens on: mitochondria and cytosol.
        Is slower
        Uses: oxygen.
        Produces: 36 ATP.
        Chemical equation: Glucose + oxygen ---> CO2 + water.
    - - Anaerobic respiration: is a chemical reaction to have ATP, it happens only on the muscles.
        Produces: 2 ATP.
        Doesn't use: oxygen.
        Is faster.
        Chemical equation: Glucose ----> Lactic acid
        Happens on cytosol.
- - - - The function of the respiratory system is to carry oxygen and CO2 by a process called gas exchange.
    - - Nose: Where the oxygen enters to our body.
        Larynx: Is up the windpipe.
        Windpipe: Is the way or path by where the oxygen passes.
        Bronchus: Are 2 "branches" that go out from the windpipe.
        Lungs: On the lungs are the bronchioles and alveolus.
        Bronchioles: are the big "branches", from them go out the alveolus.
        Alveoli: Are little air sacs, they are an important part of the gas exchange.
        Muscles of ribs: Involved in the movement of the lungs.
        Diaphragm: Is down the lungs, is involved in the movement of the lungs when breathing.
    - - The oxygen enters by the nose, then the larynx, the windpipe and finally arrives at the lungs. On the lungs, it passes through the bronchi, bronchioles, and alveoli. At this time, gas exchange occurs. The alveoli are filled with oxygen. The places with high concentrations (alveoli) move to places with low concentrations (red blood cells), the diffusion not only happens with oxygen but also with the CO2 that the red blood cells have. Now the red blood cells are oxygenated, and they carry the oxygen to all the organs and the organs give them the CO2, here is happening the diffusion. This process is called gas exchange.
  - - - The function of the circulatory system is to transport oxygen, carbon dioxide, nutrients, and waste through all our bodies, this is carried by the blood.
    - - Heart: the function of the heart is to pump blood to all the body.
        Blood vessels: (arteries, veins, and capillaries): they carry the blood, the arteries carry it out from the heart, and the veins make the blood return to the heart.
    - - The heart pumps blood to the whole body through the arteries. There are many kinds of cells in the blood, one of which is red blood cells. They transport oxygen to the organs and absorb carbon dioxide from the organs. Then the blood passes through the veins to the heart to get oxygenation, and then the process begins again.
