What do capillaries do?
Exchange materials with tissues.
What do arteries do?
Carry blood away from heart.
What do veins do?
Carry blood to heart.
True or false: the right atrium & right ventricle receive deoxygenated blood from the body and send it to the FEET for gas exchange.
False, lungs.
True or false: the left atrium & left ventricle receive oxygenated blood from the LUNGS and send it to the rest of the body tissues.
True.
Atria (pl. form of atrium) r _ _ _ _ _ e blood and ventricles s _ _ d blood.
Receive and send.
Erythrocytes (red blood cells): Carry o _ _ _ _ n
Oxygen.
Leukocytes (white blood cells): Provide defense against p _ _ _ _ _ _ _ s
Pathogens.
Platelets: Play a key role in blood c _ _ _ _ _ _ g.

The human lymphatic system:
1) Recovers lost f _ _ _ d from the cardiovascular system (lymph) and returns it to the blood
2) Returns p _ _ _ _ _ _ s to the circulation
3) Transports f _ _ s absorbed by the small intestine
4) Aids in the bodies defense against foreign p _ _ _ _ _ _ _ s
Fluid, proteins, fats, pathogens.
Gas exchange occurs in the l _ _ _ s.
Lungs.
True or false: the lungs are connected to branches of trachea and bronchi (singular form bronchus)
True.
Gas exchange happens in two locations. The first occurs in the l _ _ _ s, where blood releases carbon dioxide and absorb oxygen by diffusion.
Lungs.
True or false: gas exchange happens in two locations. The second location occurs between capillaries and tissues all over the body. Oxygen is released from blood and carbon dioxide is absorb from the tissues.
True.
