Func
tion Bring nutrients and oxygen to cells.
Remove waste products so it can be excreted
Bloo
d Living tissue that circulates through the body.
Transports oxygen, nutrients, hormones and waste.
Liquid part:Consists of mainly water.Transports nutrients, waste products and gases in dissolved form.
Disc-shaped cells:Made in bone marrow.Large and flexible, with no nucleus.Transport oxygen from lungs to the rest of the body.
Larger than red blood cells, fewer in number.Protect the body against infection and disease.Fight germs when there is an infection in the body.
Smallest particle in the blood.Produced in bone marrow.Plays an important role in blood clotting.
;kajno;nd
Humans have a closed circulatory system.
This means blood circulates around the body without ever leaving the blood vessels.
Artery Vein
Arteriole Venule
Capillary network
Capillaries: Many small, narrow tubes.Walls are very thin – cells come into close contact with the blood.Capillaries supply cells with O2 and nutrients, and removes waste products and CO2. Capillaries combine again to form veins.
Veins: Transport deoxygenated blood back to lungs via the heart.Thinner, less muscled walls.The pulmonary vein transports oxygen-rich blood from the lungs to the heart. It is the only vein that transports oxygen-rich blood.
Arteries: Transport oxygen-rich blood from the heart to the cells of the body.Walls are thick, muscled and elastic - The aorta is the main artery.The pulmonary artery transports deoxygenated blood from the heart to the lungs. It is the only artery that transports deoxygenated blood.
Func
tions
ofPumps deoxygenated blood to the lungs where it gets rid of CO2.
Blood enriched with O2 flows back to the heart from the lungs.
From where it is pumped to the rest of the body. In this way the rest of the body is supplied with O2.
