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...

A.) The blood low out of the heart is about 83 mL/sec. Assuming that the blood flows equally through all capillaries, estimate the blood flow 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...

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...

The viscosity of blood is 2.10 × 10−3 Pa⋅s. * What is the pressure difference required to make blood flow through an artery of inner radius 2.00 mm and length 0.200 m at an average speed of 5.28 cm/s? ___ Pa * Blood flows through an artery of inner radius 2.00 mm and length 0.200 m at an average speed of 5.28 cm/s. What is the ratio of the pressure difference required to make blood flow through this artery to...

The left ventricle of a resting adult’s heart pumps blood at a flow rate of 83 cm3/s, and an average heartbeat increases the pressure in the vessels by 79.5 mm Hg, the speed of the blood from zero to 25 cm/s, and the height by 11.6 cm. a. Calculate the total power output of the left ventricle in W. Note that most of the power is used to increase blood pressure, and the density of blood is about 1050 kg/m3.

Q14
An ice cube is floating in a glass of water. After it has melted, has the water line in the glass increased, decreased or stayed the same? Explain. The typical diameter of the aorta is 0.005 m and that of a capillary is 10^-5 m. The average blood speed is 1.0 m/s in the aorta and 0.01 m/s in the capillaries. Assuming that all the blood that flows through the aorta must flow through the capillaries (in other words, the...

The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...
