Solution Preview

Things to keep in mind when completing a problem such as this:

1. Arteries transport blood away from the heart.
2. Veins transport blood to the heart.

Blood flow normally takes two general paths. The first is through the body also called the systemic (relating to or affecting the body as a whole rather than individual parts and organs.) circulation. The left side of the heart accomplishes the pumping action for this circulation.
The second general path of blood flow through the body is the pulmonary (related to, associated with, or affecting the lungs.) circulation. The right side of the ...

Solution Summary

This solution applies to humans and all mammals. It is an excellent guide to understanding the flow of blood through the body as it gets oxygenated and deoxygenated. There are also some links [updated] that point to webpages that are useful for further information.

Could someone please help with the following,please provide sources

(1) There are two circuits of blood flow to the body. Describe these two circuits in general terms. Beginning with the heart, which side of the heart pumps blood to each of the circuits?

(2) A separate circuit involving the coronary blood vessels serves the heart. Describe the vascular route of coronary circuit, and suggest reason(s) that we might wish to be even more familiar with the coronary circuit than the others.

(3) How does the red blood cell differ from other cells in its ability to divide and synthesize protein? Propose a reason that the red blood cell has no nucleus.
