Systemic circulation

The circulatory system with its various blood vessels is divided into two major areas, the systemic circulation and the pulmonary circulation.

The body cycle begins with the expulsion of the oxygen-rich blood from the left ventricle into the great aorta, the aorta. From the aorta branches from all other major arteries. It is divided into smaller arteries that carry blood to the various parts of the body. The small branch arteries are called arterioles, which eventually merge into the capillaries. In them, the exchange of oxygen, nutrients and waste products takes place. You are the link between arteries and veins. The capillaries merge into venules, fine blood vessels that collect the deoxygenated blood after the exchange of material. These combine to form the larger in comparison veins, which eventually lead to the upper and lower vena cava. These two large veins carry blood back to the heart and open into the right atrium of the heart.

Circulation at a glance

  • Transport of " oxygenated " blood
  • Transport of " oxygen-poor " blood

Left atrium → left ventricle → aorta → arteries → arterioles → capillaries → arterial venous capillaries → venules → veins → upper / lower vena cava → right atrium → right ventricle
