Exam 2 review BIO202

The chordae tendineae connect the flaps of the AV valves to____

• pectinate muscles

• papillary muscles

• atrial wall

• flaps of the semilunar valves

What phase of the cardiac cycle are the ventricles in during the P wave of an ECG?

• ventricular contraction

• ventricular diastole

• ventricular depolarization

• ventricular systole

Net filtration pressure is:

• hydrostatic + colloid osmotic pressure

• colloid osmotic + hydrostatic pressure

• colloid osmotic - hydrostatic pressure

• hydrostatic - colloid osmotic pressure

The walls of the right ventricle are thicker than the walls of the left ventricle

• True

• False

Only fluids can diffuse through capillaries

• True

• False

What layer of an arterial wall has the most smooth muscle?

• tunica externa

• tunica intima

• tunica media

• tunica adventitia

Which of the following factors leads to an increase in blood pressure?

• Activation of the sympathetic nervous system

• Increase in blood volume

• Increased Aldosterone in blood

• All responses lead to increased BP

When ventricular pressure is greater than atrial pressure (v > a) blood moves:

• into the atria

• into the blood vessels

• stays in the ventricle

• I have no idea
