Document Summary
Other functions: immunity (wbc attack foreign invaders), tissue repair (clotting; damage skin or something inside body, blood creates a clot which starts repair), body temp. Works in close contact with the respiratory system. Blue blood = deoxygenated blood (less o2 than when it picks it up in the lungs; doesn"t mean it has no o2) Deoxygenated blood moves from the right side of the heart to the lungs for gas exchange; blood turns from blue to red in the capillaries in the lungs (colour changes) Lots of capillaries allow for lots of sa for gas exchange. Blood will then move from the lungs to the left side of the heart once it is oxygenated. Left side of the heart is larger than the right in terms of thickness & strength. Blood pumped up goes to head; blood pumped down goes to the limbs, torso.
