The pressure in the aorta changes throughout the cardiac cycle. During systole, as the heart contracts, the outflux of blood into the aorta causes an increase in pressure, whereas during diastole the pressure decreases as the heart relaxes. A simple model for the aortic pressure waveform is given by the Windkessel effect described by the image below. In this model, the heart is considered a pressure generating pump which is directly connected to an elastic compartment (the aorta), which in turn is connected to a rigid set of peripheral vessels (the hose of the firefighter). 5 Pump Heart Air Windkessel Elastic arteries In order to find the aortic pressure waveform from the Windkessel model, a mass balance formulation around the aorta must be formulated. Coming into the aorta from the heart we have the flowrate Q(t). According to conservation of mass, this inflow rate Q(t) must be equal to the outflow rate into the peripheral vessels and the change in volume of the aorta. To find these…
Diagrammatically explain the phenomenon of counter current multiplication.
The aorta is the principal blood vessel through which blood leaves the heart in order to circulate around the body. (a) Calculate the average speed of the blood in the aorta if the flow rate is 5.0 L/min. The aorta has a radius of 10 mm. (b) Blood also flows through smaller blood vessels known as capillaries. When the rate of blood flow in the aorta is 5.0 L/min, the speed of blood in the capillaries is about 0.33 mm/s. Given that the average diameter of a capillary is 8.0 μm (1 μm = 1 X 10 –6 m), calculate the number of capillaries in the blood circulatory system.
Nizatidine injection (25 mg/mL) is supplied in 4-mL vials. The prescription states that for continuous infusion 'dilute 300 mg in 150 mL and give at a rate of 10 mg/hour'. If this procedure is adopted, calculate: (a) how many vials of nizatidine injection will be required (b) the flow rate (in mg/hour). NOTE: PLEASE GIVE THE ANSWER WITHIN 2 HOURS THANK YOU
Examine one of the consequences of branching with a simple model shown in the figure. Assume that there are two blood-flow circuits, which are identical except that one of the circuits has a single vessel, whereas the other has two identical vessels in parallel. a.If the resistance of a single vessel is R, what is the overall resistance of the two vessels in parallel? b.If each of the circuits carries the same flow rate, which has the larger pressure drop? Comment on the result.
Please use this formula Va=(Vt-Vd)×RR TV=Vt
What is the blood flow rate through a vessel given the following: ΔP = 120 mmHg; radius = 6 mm; length = 20 mm; and viscosity of the blood = 4.5? ? (conversion factors: 1 mmHg = 0.013 dynes/cm2 and a viscosity of 1.0 = 0.01 dyne sec/cm2)
Using your own words, What is meant by the “Counter Current System”?
By how much would a blood vessel need to expand using vasodilation to increase blood flow by 200% (3x)?
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
Unlike the discrete waveform from an electrocardiogram, the electromyogram waveform is irregular. Why do you suppose this is?
a) A consequence of the Frank-Starling law of the heart is that the outputs of the right and left ventricles match. Explain why this is important and how this match is made.b) The excitation-contraction matching mechanism within the heart muscle is different from that of the skeletal muscle. How might these differences be related to the difference between action potentials in cardiac muscle and skeletal muscle?
