Question

Describe systemic circulation.

Short answer

The systemic circulation provides the functional blood supply to all body tissue.

Step-by-step solution

Step 1. Introduction

The movement of the blood in all body parts is termed circulation.

The blood circulation in the entire body is made possible by a powerful organ: the heart.

The heart is made up of muscles that ensure blood pumping into various body regions.

A septum, or muscle wall, usually separates the left and the right side of the heart. This ensures that the blood rich in oxygen does not mix with the blood poor in oxygen or rich in carbon dioxide.

It also acts as a routing station between the pulmonary and systemic circuits.

Step 2. Explanation 

• In the systemic circulation, the blood is pumped from the heart to all other body parts and then back to the heart again.
• The blood vessels of this type of circulation connect the heart to other body tissues. The blood leaving the heart and getting distributed to all other body parts is usually oxygenated, while the blood coming from the body tissue and back to the heart is deoxygenated.
• Systemic circulation is also referred to as thesystemic circuit.
