BIOLOGY
FUNCTIONHelps keep your body at the RIGHT
TEMPERATURECarries HORMONES to the body cellsSENDS ANTIBODIES to fight infectionContains CLOTTING FACTORS to clot blood and
the bodies tissue to HEALTransport OXYGEN and NUTRIENTS throughout
the bodyRemove waste materials such as CARBON DIOXIDE
Fluid part of blood & Carries carbon dioxide, hormones and waste
Contain haemoglobin which carries oxygen &
Made in the bone marrow. The more you train the more red
blood cells are made.
Important part of the immune system, they produce antibodies and
destroy harmful micro organisms
Clump together form clots & Protect the body by stopping bleeding
The heart pumps blood out through one main artery called the dorsal aorta. The main artery then divides and branches out into many smaller arteries so that each region of your body has its own system of arteries supplying it with fresh, oxygen-rich blood.
Veins receive blood from the capillaries after the exchange of oxygen and carbon dioxide has taken place. Therefore, the veins transport waste-rich blood back to the lungs and heart. It is important that the waste-rich blood keeps moving in the proper direction and not be allowed to flow backward. This is accomplished by valves that are located inside the veins. The valves are like gates that only allow traffic to move in one direction
Unlike the arteries and veins, capillaries are very thin and fragile. The capillaries are one epithelial cell thick. The exchange of oxygen and carbon dioxide takes place through the
thin capillary wall. The red blood cells inside the capillary release their oxygen and take
in carbon dioxide and waste products
