Blood circulates through a network of vessels throughout the body to provide individual cells with oxygen and nutrients and helps dispose of metabolic wastes. The heart pumps the blood around the blood vessels. Functions of blood and circulation:

How does the blood circulatory system work? March 12, ; Last Update: August 1, ; Next update: The blood circulatory system cardiovascular system delivers nutrients and oxygen to all cells in the body.

It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.

The system of blood vessels resembles a tree: The smallest arteries end in a network of tiny vessels, the capillary network.

There is not only one blood circulatory system in the human body, but two, which are connected: The systemic circulation provides organs, tissues and cells with blood so that they get oxygen and other vital substances.

The pulmonary circulation is where the fresh oxygen we breathe in enters the blood. At the same time, carbon dioxide is released from the blood. Blood circulation starts when the heart relaxes between two heartbeats: The following phase is called ejection period, which is when both ventricles pump the blood into the large arteries.

In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery aorta. The blood travels from the main artery to larger and smaller arteries into the capillary network. There the blood releases oxygen, nutrients and other important substances and takes on carbon dioxide and waste substances.

The blood, which is now low in oxygen, is now collected in veins and travels to the right atrium and into the right ventricle. Now pulmonary circulation starts: The right ventricle pumps blood that carries little oxygen into the pulmonary artery, which branches off into smaller and smaller arteries and capillaries.

The capillaries form a fine network around the pulmonary vesicles, grape-like air sacs at the end of the airways. This is where carbon dioxide is released from the blood into the air contained in the pulmonary vesicles and fresh oxygen enters the bloodstream.

When we breathe out, carbon dioxide leaves our body. Oxygen-rich blood travels through the pulmonary vein and the left atrium into the left ventricle. The next heart beat starts a new cycle of systemic circulation.The heart, blood, and blood vessels make up the cardiovascular component of the circulatory system.

The Cardiovascular System (Heart and blood) | Medical Terminology for Cancer

It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated. The cardiovascular system circulates blood and lymph through the body and it consists of the heart, blood vessels, blood, lymph, and the lymphatic vessels and glands. It is responsible for transporting oxygen, nutrients, hormones, and waste products through the body.

The system of blood vessels resembles a tree: The “trunk,” the main artery, branches into large arteries, which lead to smaller and smaller vessels. The smallest arteries end in a network of tiny vessels, the capillary network. Learn anatomy lab cardiovascular system blood vessel with free interactive flashcards.
