The structure marked by the white arrow (A) is found between the right and left ventricles (B) is found between the right and left atria (C) closes before birth (D) A and C (E) B and C

If a patient has cirrhosis of the liver and is unable to produce sufficient albumin and other plasma proteins, then what variable is changed in capillary exchange, and what is the effect? a. There is no change in the capillary exchange process. b. Hydrostatic pressure in the blood decreases, and fluid remains in the blood. c. Colloid osmotic pressure in the capillary increases, and blood volume increases in the blood vessels. d. Colloid osmotic pressure in the capillary decreases, and fluid remains in the interstitial fluid, potentially causing edema.

Which of the following is/are true concerning the opening and closing of the cardiac valves? A. valves operate according to the pressures on either side of the valve B. valve operation is constantly being controlled by the medulla oblongata C. valve operation is determined directly by the cardiac action potential (electrical currents control the opening and closing of the valves.) D. valve operation is directly controlled by the papillary muscles within the ventricular wall. E. None of the above is correct.

How would you explain the flow of electrical activity through the heart to a 5-year-old?

The blood vessels responsible for variably distributing cardiac output among organs in the body are: a. Veins b. Arteries c. Capillaries  d. Arterioles

In a healthy adult blood flow in the left coronary artery is less during systole than diastole. This difference is best explained by a change in which of the following (a) Coronary arterial Po2 (b) Extravascular Pressure (c) Flow through the aortic valve (d) Parasympathtic nerve activity (e) Sympathetic nerve activity

Blood within the veins is prevented from flowing away from the heart because of the presence of: (a) venous reservoirs. (b) muscular walls. (c) clots. (d) valves.

Which portion of the heart contains the most myocardium? Select one: a.right atrium b.left atrium c.left ventricle d.right ventricle e.both right and left ventricles

An atrial septal defect is a birth defect in which there is an opening in the septum between the left and right atria. People with such a defect typically have more than a normal amount of blood in the right atrium. Why does blood flow from left to right across the septum rather than in the opposite direction? The excess of blood can cause hypertension in one circuit. Which one?

Bicuspid or mitral 3. layer that immediately covers the heart muscle C. brachiocephalic 4. middle layer of the heart D. Chordae tendineae 5. Area that grossly demonstrates the separation between the atria and ventricles E. Coronary sinus 6. The two major vessels returning blood to the right atrium F. Coronary sulcus G.
