Question
hi pep 7B.10 (G) Only a fraction of the total cardiac output is seen by any en by any organ. For 14% of the example, the brain receives 0.7 L/min of blood flow, which is total cardiac output of a resting person. Table 7B.10 shows the c of some other organs of the body (a) Complete Table 7B.10. Consult textbooks or journals as necesary During exercise, the cardiac output increases, allowing for the muscles rsecive more nunrients. The disribution of blood through the body chag as shown in Table 7B.11. TABLE 7B.10 Cardiac Output at Rest Flow rate through organ (Umin) 0.7 Percent of cardiac output (%) 14 18 Organ Brain Muscles Gl system, spleen, and liver Skin Bone Kidneys Other 1.35 TABLE 7B.11 Cardiac Output During Exercise Flow rate through organ compared to rest Same Organ Brain Muscles GI system, spleen, and liver Skin Bone Kidneys Other Reduce 50% Increase fourfold Same Reduce 50% SameExplanation / Answer
Answer 7B. Cardiac output at rest :-
Flow rate to the muscles during exercise is highly increased. This is due to the high demand of food and oxygen of the exercising muscles. So the supply has to increase in order to meet the increased demand of the exercising muscles.
Answer C. The muscle receive 18% of the cardiac output thus if cardiac output is 12.8 L/min then blood flow to the muscle will be 18% of the 12.8 that is 2.3 L/min.
Answer D. During exercise, the amount of blood to the skin increases fourfold because the body has to maintain homeostasis. The temperature of the body is maintained by increasing blood flow to the skin by sweating.
