Write the following structures into sequence as a drop of blood would pass them on the double circuit of a mammalian system. aorta to systemic arteries and arterioles aortic semilunar valve inferior and superior vena cavae left atrioventricular valve (also called biscupid or mitral valve) left atrium left ventricle pulmonary capillaries to venules pulmonary trunk/arteries to arterioles pulmonary semilunar valve pulmonary veins right atrioventricular valve (also called tricuspid valve) right atrium right ventricle systemic capillaries to venules and veins
_____ contraction drives blood through the systemic and pulmonary circuits; outside the heart, blood pressure is highest in the _____. a. Atrial; ventricles b. Atrial; atria c. Ventricular; arteries d. Ventricular; aorta
The human circulatory system isclosed—that is, the blood pumped out of the left ventricle of the heartinto the arteries is constrained to a series of continuous, branching vesselsas it passes through the capillaries and then into the veins as it returnsto the heart. The blood in each of the heart’s four chambers comesbriefly to rest before it is ejected by contraction of the heart muscle. The velocity of blood in the aorta can be measured directly with ultrasound techniques. A typical graph of blood velocity versus time during a single heartbeat is shown in Fig. . Which statement is the best interpretation of this graph? (a) The blood flow changes direction at about 0.25 s; (b) the speed of the blood flow begins to decrease at about 0.10 s; (c) the acceleration of the blood is greatest in magnitude at about 0.25 s; (d) the acceleration of the blood is greatest in magnitude at about 0.10 s.
In the cardiovascular dynamics experiment (part 2), if the left flow tube represents the pulmonary veins, what does the left source beaker represent? pernen on Select one: the right atrium O the left atrium O the pulmonary artery O blood coming from the lungs In the cardiovascular dynamics experiment (part 2), when the piston of the pump reaches lowest point, the volume remaining in the pump is the REDMI NOTE 9 PRO ZATAB_26 00
How many steps (inhalations/exhalations) are needed to complete one ventilatory cycle in birds? O 3 breaths in/3 breaths out O 2 breaths in/2 breaths out O More than 4 of each O 1 breath in/1 breath out O 4 breaths in/4 breaths out
Identify the ventricle of the heart that pumps oxygendepletedblood and the arteries of the body that carryoxygen-depleted blood.
Trace the flow of blood through a mammalian heart, naming the four chambers and their valves, and explaining where the blood entering each atrium comes from and where blood leaving each ventricle goes. When the ventricles contract, what prevents blood from reen-tering the atria? What factors cause blood to move forward at high pressure in the aorta?
Why do the cardiac muscles cells demonstrateautorhythmicity?
Put the structural components provided in the order that an oxygen molecule travels by matching them with numbers 1-5. (Not all structures will be used.) Left ventricle, aorta, left atrium, right ventricle, right ventricle, alveolus, cell, right atrium
You are studying bulk flow in a tissue. You have measured the following: Blood pressure at the arterial end of the capillary – 30mmHg Osmotic pressure at the arterial end of the capillary – 20 mmHg partial pressure of oxygen at the arterial end of the capillary – 42 mmHg; partial pressure of CO2 – 40mmHg partial pressure of O2 at the venous end – 42 mmHg; partial pressure of CO2 – 46mmHg Blood pressure at the venous end of the capillary – 14mmHg Osmotic pressure at the venous end of the capillary – 20 mmHg Pick all that would apply A)the 10 mm Hg pressure difference will drive blood plasma into the interstitial fluid B)the 6 mm Hg pressure difference will drive blood plasma into the interstitial fluid C)the hydrostatic pressure declines from the arterial side to the venous side because oxygen is lost. D)the pH is lower on the arterial side than on the venous side. E)the osmotic pressure remains constant due to carbon dioxide compensation. F)oxygen is taken up by the…
