Blood flow through the cardiovascular system is governed by a pressure gradient, ΔP, that causes blood to flow from high pressure areas to lower pressure areas. Which of the following creates the high pressure?

Homework Answers

Answer #1

The blood pressure is form when the left ventricle of the heart compression takes place. This compression create a high blood pressure that flows into the vessels from arteries to the capillaries and then into the veins. The blood also flows like all body fluids from higher blood pressure to lower blood pressure gradient: arteries to capillaries to veins.

The rate of speed of blood greatly depends upon the total cross section of area of blood vessels. The rate of blood flow is inversely proportional with the total cross-sectional area of the blood vessels. The speed of blood decreases as the total cross section area of blood vessels increases.

The rate of blood pressure also depends upon the viscosity of the blood ,gravity of the earth, cardiac output, and peripheral resistance. When these factors changes the blood pressure also changes

Trace a drop of blood through the cardiovascular system starting at your right ventricle, traveling through your body to your lower leg, and returns to your right atrium. HINTS: Don't forget the pulmonary vessels! Focus on the major vessels of your body and not all of the tiny arteries and veins. You should get down to capillaries where appropriate.
