Iliac Arteries

The Iliac Arteries are an important part of the circulation of the lower extremities and pelvis. These arteries are among the large arteries that belong to the abdominal cavity and their function is to transport blood from the aorta to the lower part of the body.

The abdominal aorta, which is the largest artery of the body, passes through the abdominal cavity and eventually divides into two common iliac arteries at the level of the fourth lumbar vertebra. One common iliac artery goes to the right, and the other to the left.

Each common iliac artery, upon reaching the pelvic region, is divided into two important arteries - the external iliac artery and the internal iliac artery.

The external iliac artery supplies blood to the lower limb, running along the outer surface of the thigh, and the internal iliac artery supplies the internal pelvic organs, such as the bladder, rectum, pelvic organs and genitals.

In addition, the internal iliac artery gives branches to the bladder, prostate and uterus, as well as to the gluteal region, including the muscles of the gluteal region and the skin. Thus, the Iliac Arteries play an important role in maintaining blood circulation in the lower part of the body.

In conclusion, the Iliac Arteries are important arteries supplying blood to the lower limbs and pelvis. Their division into the external and internal iliac arteries provides blood supply to various organs and tissues, making them essential for the proper functioning of the human body.

The iliac arteries are the arteries that supply blood to the lower limbs and pelvic region. They are branches of the abdominal aorta.

The abdominal aorta (aorta abdominalis) is the largest artery in the human body. It starts from the diaphragm and passes through the abdominal cavity to the pelvis. The abdominal aorta is divided into two common iliac arteries - the right and left. Each of them, in turn, is divided into the external and internal iliac arteries.

The external iliac arteries pass through the external iliac foramina and reach the hip joint. They supply blood to the lower limb, thigh, buttock and part of the pelvic region. The internal iliac arteries also pass through the internal iliac foramina, but they are smaller and do not reach the hip joint, but continue on their way to the pelvic organs.

The iliac arteries play an important role in the blood supply to the lower limb and pelvis. They provide blood with oxygen and nutrients for muscles, bones, joints and pelvic organs. Impaired blood flow in these arteries can lead to various diseases, such as varicose veins, thrombosis, coronary heart disease and others. Therefore, it is important to monitor the condition of the iliac arteries and take measures to prevent their diseases.

The iliac arteries are one of the most important arteries in the human body, supplying blood to the lower limbs, hips and pelvic region. They have several components that ensure high efficiency of blood supply in this area.

The main source of supply of blood vessels is the common iliac artery, which from the common iliolumbar artery passes through the body of the main bone of the abdominal cavity along the way. Each ilium is divided in half, forming the external iliac artery (anterior) and internal iliac artery (posterior) iliac arteries. The external arteries are carried outward from the thighs. The internal arteries cross and continue down to the groin and reproductive organs.

**Iliac arteries** are arteries in the abdominal cavity that supply blood to the lower extremities. Venous blood from the lower extremities collects in large veins, the so-called deep veins, and is then transferred to the main venous trunk, also called the great vein (cava).

The iliac branch of each common femoral artery branches off from the abdominal aorta at its bifurcation. The left common iliac artery (a. pisciformis) is long and thin, while the right one is short and thick. The iliac branches are a continuation of the common iliac artery and descend deep to the sacral region. They are named according to their position on the left or right side.

**Branch A** - obturator artery. This is the only branch that runs vertically in the lower part of the thigh. It supplies blood to the skin and skin on the front of the thigh, as well as the white ligaments, scrotum, thigh skin and joints. Its continuation above is located in the popliteal fossa, where the last artery branches to the lower leg; the same blood as in the front of the knee.

Branch B, the superior gluteal artery, supplies the upper abdominal region and the hip bone with the anterior layer of the gluteal muscle.
