BMS 300 Exam 3 Keyed Interactive (100% accurate)

deoxygenated blood is carried away from the heart through the: a. vena cava b. aorta c. pulmonary artery d. pulmonary vein e. coronary artery correct answers c. pulmonary artery cardiomyocytes receive oxygen from blood in the a. atria b. ventricles c. aorta d. myocardial capillaries e. all except d are correct correct answers d. myocardial capillaries in fish, oxygen enters the blood from water by crossing: a. gill epithelium b. capillary endothelium c. atrium d. ventricle e. a and b are correct correct answers e. a and b are correct the pressure that closes the ________ moves blood through the _______. a. left atrioventricular valve, capillaries of the hw right and left ventricular myocardium b. pulmonary valve, capillaries of the right ventricular myocardium c. aortic valve, capillaries of the left and right ventricular myocardium d. right AV valve, capillaries of only the right ventricular myocardium e. aortic valve, pulmonary capillaries correct answers c. aortic valve, capillaries of the left and right ventricular myocardium papillary muscles are specialized muscles in the ventricles that are attached to the AV valves and ensure that these valves remain closed as ventricular pressure increases. you would expect these muscles to contract and generate tension: a. when blood enters the ventricles b. when the atrial myocardium contracts c. during the isovolumetric relaxation phase d. during the isovolumetric contraction phase e. all except c are correct correct answers .d. during the isovolumetric contraction phase the greatest reduction in the amount of oxygen bound to hemoglobin occurs in the: a. capillaries between the arterioles and the veins b. arterioles between the arteries and capillaries c. arteries between the aorta and the arterioles d. veins between the capillaries and the vena cava
