| Question | Answer |
|---|---|
| A disease that develops as a result of the reaction of a mother’s Rh antibodies with her Rh-positive baby is | erythroblastosis fetalis. |
| A decrease in the amount of white blood cells is called | leukopenia. |
| Neutrophils are highly mobile and phagocytic. They migrate out of blood vessels and into tissue spaces. This process is called | diapedesis. |
| All of the following are components critical to coagulation except | prothrombin. thrombin. fibrinogen. fibrin. none of the above; all of these components are critical to coagulation |
| _____ is used to determine the volume percentage of red blood cells in whole blood | Hematocrit |
| Platelets play an important role in | blood clotting. |
| Which of the following is not a formed element found in the blood? | plasma |
| A glycoprotein hormone that is secreted to increase oxygen concentration in the tissues is | erythropoietin |
| Which division of the autonomic nervous system sends fibers to the heart? | sympathetic & parasympathetic both A and B |
| A type of abnormal heart sound that may signify incomplete closing of the valves is | a heart murmur. |
| Mechanical devices that permit the flow of blood in one direction only are called | valves. |
| A graphic record of the heart’s electrical activity is a(n) | ECG. |
| The heart valves that are located where the trunk of the pulmonary artery joins the right ventricle and where the aorta joins the left ventricle are called | semilunar valves. |
| The normal ECG is composed of all of the following except a | E wave. |
| The type of membranous tissue that lines the heart and blood vessels is the | endothelium. |
| The bulk of the heart wall is the thick, contractile middle layer called the | myocardium. |
| Which sphincters function as regulatory valves that reduce the flow of blood through a network of capillaries when they contract and constrict the arterioles? | precapillary sphincters |
| Blood from the brachiocephalic vein drains into the | head, neck, and upper extremity. |
| The internal iliac artery supplies blood to the | pelvis. |
| Renal veins drain blood from the | kidneys. |
| Blood flow from the heart through blood vessels to all parts of the body and back to the heart is referred to as _____ circulation. | systemic |
| During pregnancy, what happens to the oxygenated blood returned from the placenta via the umbilical vein? | It flows into the inferior vena cava. |
| Which types of arteries are also called conducting arteries and include the aorta? | elastic arteries |
| Starling’s law of the heart states that, within limits, the longer, or more stretched, the heart fibers are at the beginning of the contraction, the | stronger the contraction. |
| The vagus is said to act as a “brake” on the heart. This situation is called | vagal inhibition. |
| Blood viscosity stems mainly from the red blood cells but also partly from the _____ in blood. | protein molecules present |
| Cardiac output is determined by | stroke volume and heart rate. |
| The mechanisms of which three hormones work together to regulate blood volume? | aldosterone, ANH, and ADH |
| The term used to describe the collection of mechanisms that influence the circulation of blood is: | hemodynamics. |
| Which two factors promote the return of venous blood to the heart? | blood-pumping action of respirations and skeletal muscle contractions |
