Vessel

A vessel is a duct or channel through which any biological fluid passes through the body. There are blood and lymphatic vessels.

Blood vessels carry blood throughout the body. These include arteries, veins and capillaries. Arteries carry blood from the heart to organs and tissues. Veins return blood back to the heart. Capillaries connect arteries and veins, ensuring the exchange of substances between blood and tissues.

Lymphatic vessels make up the lymphatic system. They collect lymph from tissues and organs and return it to the bloodstream. Lymph carries immune system cells and metabolic products. Thus, lymphatic vessels maintain water-salt balance, immunity and remove waste from the body.

Vessels play an important role in the functioning of many body systems. Violation of their structure and functions leads to serious diseases.

A vessel is a duct or channel through which any biological fluid (blood or lymphatic vessel) passes through the body.

Vessels are divided into arteries, veins and capillaries. Arteries carry blood from the heart to organs and tissues. Veins return blood back to the heart. Capillaries connect arteries and veins, ensuring the exchange of substances between blood and tissues.

The walls of blood vessels consist of endothelial cells, connective tissue and smooth muscle. Thanks to the muscle layer, blood vessels can narrow and dilate, regulating blood flow.

The vascular system plays a critical role in the body, providing transport of blood, nutrients, hormones, oxygen and other essential components. Disturbances in the structure and functioning of blood vessels can lead to serious diseases.

Vessel is the ducts and channels through which biological fluid, such as blood or lymph, flows in the human body. Vessels are an integral part of the circulatory and lymphatic systems, which transport oxygen and nutrients throughout the body.

In the human body, blood vessels perform many functions, including transporting blood and lymph, maintaining pressure in the vessels and regulating body temperature. They are also involved in the body's immune defense, as immune system cells such as white blood cells can travel through blood vessels to fight infections and disease.

Vessels can come in different sizes and shapes, and their number in the body can vary depending on age, gender and other factors. For example, the heart has large vessels called arteries that carry blood from the heart to the rest of the body. At the same time, the lungs have small vessels called capillaries that allow the exchange of oxygen between air and blood.

The importance of blood vessels for human health cannot be overestimated. They are key elements in maintaining normal body function and preventing various diseases. Therefore, it is important to monitor the condition of the blood vessels and take measures to maintain them.
