CIRCULATORY SYSTEM - Coggle Diagram

- - - - is working with the respiratory system,digestive system and renal system to make sure the body is alive.
  - - - The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen.
        
        Our heart is made up of three layers of tissue:
        
        epicardium
        
        myocardium
        
        endocardium
    - - Your blood is pumped around your body through a network of blood vessels:
        
        arteries
        
        they carry oxygen-rich blood from your heart to all parts of your body, getting smaller as they get further away from the heart.
        
        capillaries
        
        they connect the smallest arteries to the smallest veins, and help exchange water, oxygen, carbon dioxide and other nutrients and waste substances between the blood and the tissues around them.
        
        veins
        
        they carry blood, lacking in oxygen, back towards your heart, and get bigger as they get nearer your heart.
    - - a liquid that carries material throughout the body.
        
        red blood cells
        
        Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
        
        white blood cells
        
        White blood cell, also called leukocyte or white corpuscle, a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease by ingesting foreign materials and cellular debris, by destroying infectious agents and cancer cells.
        
        platelets
        
        Platelets are only about 20% of the diameter of red blood cells. The normal platelet count is 150,000-350,000 per microliter of blood, but since platelets are so small, they make up just a tiny fraction of the blood volume. The principal function of platelets is to prevent bleeding.
        
        plasma
        
        The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body. Blood plasma also carries all parts of the blood through your circulatory system.
- - - - is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
      - Organs of lymphatic system
