33
Q

Statins

A

A class of drug that is used to lower cholesterol levels in the blood.

Capillary

A

A very small blood vessel with thin walls and a small diameter used for substance exchange in tissues.

43

Q

Ventricle

A

A type of chamber in the heart which receives blood from the atrium above it and pumps it out of the heart.

54
Q

Ventricular systole

A

The phase in the cardiac cycle following atrial systole where the
ventricles contract and force the blood out of the heart and around the body.

55
Q

Venule

A

A smaller type of blood vessel that connects capillaries with veins.
