Anatomy and Physiology 2 Final Exam Already Graded A

Anatomy and Physiology 2 Final Exam Already Graded A The major stimulus for release of parathyroid hormone is ️Humoral The anterior pituitary secretes all but ️ADH A hormone not involved in glucose metabolism is ️Aldosterone Parathyroid hormone ️Demineralizes bone and raises blood calcium levels Important anabolic hormone, many of its effects mediated by IGFs ️Growth hormone Cause the kidneys to conserve water and or salt ️Aldosterone and ADH Stimulates milk production ️Prolactin Tropic hormone that stimulates the thyroid gland to secrete thyroid hormone ️Lutenizing hormone Increases uterine contractions during birth ️Oxytocin Major metabolic hormones of the body ️t4 and t3 Causes reabsorption of sodium ions by the kidneys ️Aldosterone Tropic hormone that stimulates the thyroid gland to secrete thyroid hormone ️TSH Secreted by the posterior pituitary ️ADH and Oxytocin The only steroid hormone in the list ️Aldosterone A hypodermic injection of epinephrine would ️Increase heart rate, increase blood pressure, dilate the bronchioles, ad decrease digestive activity Testosterone is to the male as which hormone is to the female ️estrogen If the anterior pituitary secretion is deficient in a growing child, the child will ️become a dwarf but have fairly normal body proportions If there is adequate carbohydrate intake, secretion of insulin results in ️lower blood glucose levels increased cell utilization of glucose storage of glycogen Hormones ️are carried to all parts of the body in the blood Some hormones act by ️increasing the synthesis of enzymes converting an inactive enzyme into an active enzyme affecting only specific target organs Absence of thyroid hormone would result in ️depression of the CNS and lethargy The blood volume in an adult averages approximately ️5L The hormonal stimulus that prompts red blood cell formation is ️erythropoietin All of the following are true of RBC except ️Contain nuclei The most numerous WBX is the ️neutrophil Blood proteins play an important part in ️blood clotting immunity maintenance of blood volume The WBC that releases histamine and other inflammatory chemicals is the ️basophil the blood cell that can become an antibody secreting cell is the ️lymphocyte which of the following does not promote multiple steps in the clotting pathway ️factor XI the normal pH of the blood is about ️7.4 Suppose your blood is AB positive this means that ️agglutinogens A and B are present in your RBC there are no anti A or anti B antibodies in your plasma your blood is RH+ When the semilunar valves are open which of the following are occurring ️av valves are closed ventricles are in systole blood enters aorta blood enters pulmonary arteries The portion of the intrinsic conduction system located in the superior inter ventricular septum is the ️AV bundle an EKG provides information about ️movement of the excitation wave across the heart The sequence of contraction of the heart chambers is ️both atria followed by both ventricles the fact that the left ventricular wall is thicker than the right reveals that it ️pumps blood against greater resistance the chord tendineae ️prevent the av valve flaps from everting In the heart which of the following apply ️action potentials are conducted from cell to cell across the myocardium via gap junctions the sa node sets the pace for the heart as a whole spontaneous depolarization of cardiac cells can occur in the absence of nerve stimulation freshly oxygenated blood is first received by the ️left atrium Which statement does not accurately describe veins ️always carry deoxygenated blood total peripheral resistance ️is inversely related to the diameter of the arterioles which of the following can lead to decreased venous return of the blood to the heart ️damage to the venous valves arteriole blood pressure increases in response to ️increasing stroke volume increasing heart rate atherosclerosis rising blood volume Which of the following would not result in the dilation of the terminal arterioles and upstream arterioles in the systemic capillary beds ️a local increase in pH the structure of a capillary wall differs from that of a vein or an artery because ️i.t has a single tunic only the tunica intima the baroreceptors in the carotid sinus and aortic arch are sensitive to ️changes in arterial pressure the myocardium receives its blood supply directly from the ️coronary arteries
