The Cardiovascular System + Blood

Blood plasma

• is a total of only 3 molecules.

• is approximately 90% water.

• is considered a cellular element of blood.

• plays an important role in carrying oxygen through the blood.

• performs hemolysis on RBCs

Identify the structure highlighted in red

(a)  

A drop of blood returning to the heart from the head region would enter the heart through which vessel

• a pulmonary vein

• the inferior vena cava

• the superior vena cava

• the coronary sinus

• the hepatic vein

Identify the structure highlighted in red

(a)  

The left ventricular wall of the heart is thicker than the right ventricular wall, so it can

• accommodate a greater volume of blood.

• expand the thoracic cage during diastole.

• pump blood with greater pressure.

• pump blood through a smaller valve.

• it is more susceptible to infections

Cells of the conducting system located between the AV node and bundle branches

• chordae tendineae

• purkinje fibers

• SA node

• papillary muscles

• atrioventricular bundle

The heart chamber that pumps oxygenated blood to the systemic circuit is the

• right atrium

• left atrium

• right ventricle

• left ventricle

• superior vena cava

The right ventricle pumps blood into the

• aorta

• pulmonary vein

• pulmonary trunk

• right atrium

• left ventricle
