All of the followings are incorrect, except ---------------------.A. The mean blood pressure increases with distance from the heart.B. The linear rate of blood flow is proportional to total cross-sectional area.C. The highest blood velocity occurs at the capillaries. D. Most capillaries consist of a single layer of endothelial cells E. Filtration occurs in venous capillarie

1.Outline the flow of blood through the heart starting with largest veins. Include all chambers, valves, and major arteries. Use the format A> B-→ to

Identify the name and function of five structures on the following diagram. B. A Blood returning Blood coming to the heart from the heart D E

The systemic circulation ends at the: A.right atrium B. right ventricle C. left atrium D. left ventricle The period of ejection: A. begins with the first heart sound and ends with the opening of the AV-valve. B. begins with the second heart sound and ends with the closing of the AV-valve. C. begins with the second heart sound and ends with the opening of the Aortic-valve. D. begins with the opening of the Aortic-valve and ends with the second heart sound. The arterial p02 is relatively low in an individual suffering from congestive heart failur because: A. hemoglobin is mis-shapen and can't bind adequate 02 B. pulmonary ventilation is compromised by the decrease in arterial pCO2 bronchoconstriction increases the total amount of air in the alveoli 02 has difficulty diffusing through the fluid trapped in the lung tissue he volume of blood ejected by the heart per minute is termed: stroke volume cardiac output end diastolic volume end systolic volume ght and Left Ventricular Pressures are…
