Functions:
Respiration-delivers oxygen to the cells and removing carbon dioxide from them
Nutrition-carries digested food substances to the cells of the body
Waste Removal-disposes of waste products and poisons that would harm the body if they accumulated
Immunity-disposes of waste products and poisons that would harm the body if they accumulated
Cellular Communication-the circulatory system provides a mode of transport for hormones
Thermoregulation-the circulatory system transports heat (can both warm and cool body)
How It Works:
The circulatory system consists of three systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic). The system is responsible for the flow of blood, nutrients, oxygen and other gases, and as well as hormones to and from cells.
Types of Cells:
Red Blood Cells-Carry oxygen and carbon dioxide. They pick up oxygen in the lungs and transport it to all the cells in the body. After delivering the oxygen to the cells, it gathers up the carbon dioxide(a waste gas produced as our cells are working) and transports it back to the lungs where it is removed from the body when we exhale(breath out).
White Blood Cells-Help the body fight off germs. They attack and destroy germs when they enter the body. When you have an infection your body will produce more White Blood Cells to help fight an infection.
Platelets: Blood cells that help stop bleeding. When we cut ourselves we have broken a blood vessel and the blood leaks out. In order to plug up the holes where the blood is leaking from, the platelets start to stick to the opening of the damaged blood vessels. As the platelets stick to the opening of the damaged vessel they attract more platelets, fibers and other blood cells to help form a plug to seal the broken blood vessel. When the platelet plug is completely formed the wound stops bleeding.
