A. Estimate the total work performed by the heart. Clearly state any assumptions and express your answer in J/kg.B. The ascending aorta is approximately 2.6 cm in diameter. The aortic arch is approximately 5 cm above the heart. What is the pressure in the aorta at the beginning of the aortic arch during discharge? (You can assume the blood is experiencing hichehnningles) Clearly state any assumptions. The typical rate at which blood is expelled from the heart is about 100 mL s¹ (1x104 m³ s¹). Blood entersthe right half of the heart at a pressure of about 0 Pascal and flows to the lungs at a mean pressure of1,466 Pascal. Blood returns to the left half of the heat through the pulmonary veins at a mean pressureof 1,067 Pascal. The blood is then discharged from the heart through the aorta at a mean pressure of12,000 Pascal.HeartRightLeft

Blood pressure is usually given as the ratio of the maximum pressure (systolic pressure) to the minimum pressure (diastolic pressure). For example a typical value for this ratio for a human would be 120/70, where the pressures are in mm Hg (millimeters of mercury, SG = 13.6). What would these pressures be in kPa (kilo Pascals)?: (a) systolic pressure (kPa), (b) diastolic pressure (kPa).
Assume the following pressures on the arterial end of a capillary: Plasma hydrostatic pressure = 35mmHg Plasma osmotic pressure = 26mmHg Interstitial hydrostatic pressure = 0mmHg Interstitial osmotic pressure = 1mmHg Given the pressures listed above, what is happening to fluid in this scenario? A. Fluid is leaving the capillary B. Fluid is entering the capillary C. Fluid is leaving the cell D. Fluid is entering the cell
A normal human contains 5 liters of blood, approximately 2% of which isresident in the systemic (i.e., non-pulmonary) capillaries at any given time.(a) Assuming that the capillaries are 8 μm in diameter, estimate the totallength of capillaries in the body (excluding the lungs).(b) If an average capillary length is 1 mm, how many capillaries are therein the body?(c) Cardiac output is 5 l/min. Assuming that this is evenly distributedthroughout a parallel network consisting of the capillaries found in (b),estimate the pressure drop across the capillary bed. Assume Newtonian,laminar flow in the capillaries with μeff of 3.5 cP. What percentage ofthe total 85mmHg systemic pressure drop is this?
Estimate the volume of a human heart (in mL) using the following measurements/assumptions: Blood flow through the aorta is approximately 16.8 cm/s. The diameter of the aorta is approximately 3.0 cm. Assume the heart pumps its own volume with each beat. Assume a pulse rate of 90 beats per minute.
Systemic blood pressure is defined as the ratio of two pressures—systolic and diastolic—both expressed in millimeters of mercury. Normal blood pressure is about 120mm/80mm which is usually just stated as 120/80. What would normal systemic blood pressure be if, instead of millimeters of mercury, we expressed pressure in each of the following units, but continued to use the same ratio format? Part A) atmosheres = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part B) torr = a) 120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part C) Pa = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part D) N/ m^2 = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4 Part E) psi = a)120/ 80 b) 2.32/ 1.54 c) 0.158/ 0.105 d) 1.60x10^4/ 1.06x10^4
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…
Given: Capillaries are where the magic of gas diffusion happens. Capillaries are approximately 5-10 µm in diameter. Let’s pick an average value of 7.5 µm. A normal value of the diameter of an aortic artery is 15 mm. a. What would the Reynolds number be for blood in each vessel?

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.
