Why does the right ventricle have a bicuspid valve?   a. The low pressure generated by the right ventricle is best suited to bicuspid valve compared with a tricuspid valve b. The high pressure generated by the right ventricle would be better controlled by a bicuspid compared with a tricuspid valve c. Only a short pumping distance to the lungs is required for the bicuspid valve d. The right ventricle does not have a bicuspid valve

Describe what happens with the blood flow if each valve stop working. For example, first describe what happens with the blood flow if the tricuspid valve stops working, next describe what will happens with the blood flow when the pulmonary valve stop working, and the same for other valves.

a. Only between cardiac cycles b. Ventricular diastole c. Ventricular systole d. Throughout the cardiac cycle

Korotkoff sounds indicate:   A. Regurgitation from the ventricle into the atrium through a faulty mitral valve.   B. Backflow through the tricuspid valve.   C. Turbulence in a malformed aortic arch.   D. Systolic and diastolic viscosity.   E. Opening and closing of an artery.

What is responsible for the first heart sound (lub)?   A. Contraction of the atria. B. Contraction of the ventricles C. Closing of the atrioventricular valves D. Closing of the semilunar valves

In the aorta, Select one: a. the resistance to blood flow is high, but velocity of blood flow is low. b. the velocity of blood flow is high, but blood pressure is low. c. velocity is diminished because the total cross-sectional area is small. d. the blood pressure and blood velocity are both high. e. the resistance to blood flow and the blood pressure are both low.

Which of the following is incorrect about pulmonary circulation?  A. Pulmonary perfusion can increase during exercise with increasing the workload of right ventri. B.High distensiblity of pulmonary capillaries allow increase blood flow C. Pulmonary circulation operates at a low pressure of 15mm Hg on average  D. None of the above is Incorrect      ..

Which of the fpllowingis shared by the lymphatic vessels and cardiovascular veins? A.Valves to ensure direction of flow B.Muscle pump C.Negative intra-thoracic pressure allows return of fluid D.All answers are correct

1. In ventricular fibrillation, there is no pattern visible in the EKG. What does this mean in terms of contraction? A. contraction will have no visible pattern either and the ventricles will be unable to eject much blood B. the pattern doesn't matter; contraction of the ventricles will not be affected as long as ventricular myocytes continue to depolarize and depolarize C. the ventricular myocytes will be unable to contract C. contraction will become constant and ventricles will be unable to fill with blood   2. Which structure follows depolarization of the SA Node and atria in the cardiac conduction system? A.ventricular myocytes B.AV Node C.left and right bundle branches D.AV bundle E Purkinje fibers   3. Hypertension increases afterload for the heart which in turn  A. increases Stroke Volume B. decreases Stroke Volume C.increases Cardiac Output D.increases Venous Return

The period of ejection: A. begins with closure of the AV-valves and ends with opening of the AV- valves B. begins with opening of the aortic valve and ends with closure of the aortic valve C. begins with the P-wave and ends with the QRS-complex D. begins with the QRS-complex and ends with the T-wave
