The two upper chambers in the heart which receive blood from the veins and push it into the
ventricles - ANS atria
the two lower chambers of the heart that receives blood from an atrium and pumps it to the
arteries - ANS ventricle
a protein in red blood cells that transports oxygen to tissues - ANS hemoglobin
a salt of carbonic acid in which one hydrogen atom has been replaced - ANS bicarbonate
a tiny, thin walled, capillary-rich sac in the lungs where the exchange of oxygen and carbon
dioxide takes place - ANS alveoli
the primary vein that receives blood from the head and arms and chest and empties into the
right atrium of the heart - ANS superior vena cava
a three cusp valve that separates the right atrium from the right ventricle. It prevents backflow
of blood into the right atrium when the right ventricle contracts. - ANS tricuspid valve

, the contraction of the chambers of the heart (especially the ventricles) to drive blood into the
aorta and pulmonary artery - ANS systole
relaxation of the heart - ANS diastole
a semi lunar valve between the right ventricle and pulmonary artery which prevents blood from
flowing from the artery back into the heart - ANS pulmonary semilunar valve
a vein that carries oxygenated blood from the lungs to the heart - ANS pulmonary vein
a valve of the heart - ANS bicuspid valve
a heart valve that has 3 flaps which guards the passage from the left ventricle to the aorta and
prevents the backward flow of blood - ANS aortic valve
The largest artery in the body; it conducts freshly oxygenated blood from the heart to the
tissues. - ANS aorta
the clear fluid portion of blood - ANS plasma
cells in the blood that transport oxygen and carbon dioxide to and from the tissues - ANS red
blood cells
, Blood cells that have a role in the body's immune defense mechanisms against infection; also
called leukocytes. - ANS white blood cells
deoxygenated blood into the lungs - ANS right side of heart pumps ?
oxygenated blood to the rest of the body - ANS left side of the heart sends?
