B. Systemic Circulation
The systemic circulation is the part of the vascular system that carries blood from the left ventricle to organs and tissues of the body. As outlined above, the aorta is the major artery of the systemic circulation. It extends down the length of the chest and abdomen and reaches the pelvis dividing into two branches, the iliac arteries (see Fig. 10). Veins collect blood from the capillaries of tissues and organs (see Fig. 11). The large veins drain into the superior and inferior vena cavae that return blood to the right atrium.
