Systemic Circulation

The Systemic Circulation is a set of blood vessels that supply blood to all parts of the body, with the exception of the lungs. The systemic circulation includes:

1. Aorta and its branches. The aorta and arteries distribute oxygenated blood from the left ventricle of the heart to all organs and tissues of the body.

2. All veins through which oxygen-depleted blood from organs and tissues returns to the right atrium. These are the superior and inferior vena cava, the portal vein of the liver and their tributaries.

Unlike the systemic circulation, the pulmonary circulation includes the pulmonary arteries, pulmonary capillaries and pulmonary veins. It provides gas exchange in the lungs and does not supply other organs with blood.

Thus, the systemic and pulmonary circulation are interconnected and ensure blood circulation throughout the body in order to deliver oxygen and nutrients to all cells and remove metabolic products.

The systemic circulation is a set of blood vessels that provide blood flow to all organs and tissues of the body, with the exception of the lungs, where gas exchange occurs. This circle of blood circulation is formed by the main vessel of the body - the aorta, as well as its numerous branches - arteries.

The blood entering the aorta is enriched with oxygen and nutrients, which ensures the normal functioning of all organs and tissues of the body. The blood is then distributed through the arteries, which branch into smaller vessels - capillaries. In the capillaries, the exchange of substances between blood and tissues occurs, and the blood becomes less saturated with oxygen.

The blood then continues its journey through the veins, which carry it back to the heart. Here the reverse process occurs - the blood is saturated with carbon dioxide and other metabolic products that were produced by the tissues.

Venous blood returns to the lungs, where it is oxygenated and transformed into arterial blood. Thus, the systemic circulation ensures a continuous process of blood circulation in the body, which is necessary to maintain its vital functions.

The systemic circulation, or systemic circulation, is a collection of blood vessels that supply blood to all systems of the body. Unlike the pulmonary circulation, there is no systemic circulation, therefore the amount of blood to the organs comes through the veins from all parts of the body. For example, blood enters the liver through the femoral artery and migrates through the liver vessels. Thus, gradually all organs receive the necessary blood to function.
