Art-based Question Chapter 19 Question 28 Part A Which vein originates on the medial foot and empties into the femoral vein? ANSWER: osmotic pressure in interstitial fluid (OP if ) hydrostatic pressure in a capillary (HP c ) hydrostatic pressure in interstitial fluid (HP if ) osmotic pressure in capillary (OP c )
7/19/16, 9 : 45 PM Chapter 19 Page 24 of 47 Correct The great saphenous vein originates on the medial foot and empties into the femoral vein. Chapter 19 Reading Quiz Question 5 Part A Why is it important that blood pressure drop to lower levels as it reaches the capillary beds? ANSWER: Correct Low capillary pressures are desirable because capillaries are fragile and high pressures would rupture them. Most capillaries are extremely permeable and thus even the low pressure forces solute-containing fluids out of the bloodstream into the interstitial space. Art-based Question Chapter 19 Question 12 Part A Which of the following would be interrupted in the indirect renal mechanism if angiotensin converting enzyme (ACE) is blocked from performing its job? A B C D because capillaries depend on the lower pressure to prevent fluid exchange between the capillaries and the tissue fluid because capillaries actually need a higher blood pressure for filtration activities because capillaries are fragile and extremely permeable because capillaries actually are high-pressure vessels
7/19/16, 9 : 45 PM Chapter 19 Page 25 of 47 ANSWER: Correct Angiotensin converting enzyme (ACE) produced in the lungs and other tissues converts circulating angiotensin I to angiotensin II. Chapter 19 Chapter Test Question 8 Part A Which of the following is NOT correct regarding the relationship between pressure, flow, and resistance in the cardiovascular system? ANSWER: release of renin from the kidneys conversion of angiotensin I into angiotensin II sympathetic nervous system activity conversion of angiotensin I from angiotensinogen
7/19/16, 9 : 45 PM Chapter 19 Page 26 of 47 Correct Blood flow is inversely proportional to the resistance in the blood vessels. Chapter 19 Reading Quiz Question 4 Part A Which of the following is NOT an important source of resistance to blood flow? ANSWER: Correct Total blood volume is not an important source of resistance to blood flow. However, blood volume does have a direct effect on blood pressure. Art-based Question Chapter 19 Question 8 Part A What blood vessel experiences the steepest drop in blood pressure? The relationship between resistance and flow is the opposite of the relationship between pressure and flow.
