Homework Answers
1. Pressure(P)= Flow(Q )× Resistance(R)
MEAN ARTERIAL PRESSURE = CARDIAC OUTPUT × TOTAL PERIPHERAL RESISTANCE
Here , as per question Pressure= 0.1mm hg/ml/min and Flow = 1 L/min= 1000ml/ min
MAP= 0.1mmHg /ml/min X 1000ml/ min = 100mm Hg
2. Total peripheral resistance is the sum of all vascular resistance in systemic circulation or Systemic vascular resistance.
a/ c to question , Resistance in A (Ra ) = 5mm Hg/ml/sec;( Rb) = 10 mm Hg/ml/sec; (Rc) = 20mm Hg / ml/ sec
TPR = Ra + Rb + Rc = 5+10+ 20= 35 mmHg / ml/ sec
Add Answer to:
The resistance to blood flow through an organ is 0.1 mmHg/ml/min. The blood flow rate is...

In hemodynamics, blood flow through the cardiovascular system
can be modeled as an electric circuit in which the blood serves as
electricity, the blood vessels as resistive wires, and the heart as
a battery (see Figure 1).
Figure 1 Cardiovascular circuit model
Ohm’s law states that the voltage drop ΔV across each element,
the current I flowing through it, and its electrical
resistance R are related by ΔV = IR. In a blood vessel, pressure
difference between one vessel and...

Blood flow is 83 mL/sec through each capillary. B.) The blood pressure difference across a capillary is 20 mmHg. Assuming that a capillary is about 7um in diameter on average, and that the viscosity of blood is 0.04 poise, calculate the theoretical length of a capillary. C.) The length of a capillary can be measure directly with a microscope and it usually ranges from 0.3 to 1.0 mm. Let us assume that the average length of a capillary is 0.65...

1. An individual has a cardiac output of 5.25 L / min. The diameter of their aorta is estimated to be 22 mm and the cross-sectional area of the vena cavae is 12.5 cm2. What is the velocity of blood flow in the aorta relative to the velocity of blood flow in the vena cavae? Show your work. 2. An individual has a hepatic blood flow of 750 mL / min. The hepatic arterial pressure is 95 mm Hg and...
