kroppsvævene

Kroppsvævene, also known as the circulatory system, is a vital part of the human body responsible for transporting nutrients, oxygen, and hormones to cells and tissues, and removing waste products like carbon dioxide. It consists of the heart, blood vessels, and blood. The heart acts as a pump, pushing blood through the arteries to the rest of the body. The blood then returns to the heart through veins, where it is oxygenated and nutrient-rich before being pumped out again. The circulatory system is divided into two main circuits: the systemic circuit, which supplies oxygen and nutrients to the body's tissues, and the pulmonary circuit, which transports deoxygenated blood to the lungs for oxygenation. The circulatory system plays a crucial role in maintaining homeostasis, supporting immune function, and facilitating the body's response to stress and injury.
