The human arterial and venous system

The liver is doing respiration. Aged 70 or older Aged 50 or older and have a history of smoking or diabetes Younger than 50 and have diabetes and one or more risk factors for atherosclerosis Intermittent Claudication People who have P.

The anastomosis may be actual or potential. Weak or absent pulses in the legs or feet Sores or wounds on the toes, feet, or legs that heal slowly, poorly, or not at all A pale or bluish color to the skin A lower temperature in one leg compared to the other leg Poor nail growth on the toes and decreased hair growth on the legs Erectile dysfunction, especially among men who have diabetes Diagnosis Peripheral artery disease P.

These arteries and their branches supply all parts of the heart muscle with blood. It is unique because the blood in it is not "oxygenated", as it has not yet passed through the lungs.

The wall resists the outward pressure of blood and prevents the formation of aneurysm of the arteries. You can see the heart is sitting right in the middle. It also gives blood flow to your stomach so it's very important in digestion and all that.

Contact Us The heart receives its own supply of blood from the coronary arteries. Arteriogram An arteriogram provides a "road map" of the arteries. All of these different branching points have different names to them, but you can see right here you have kind of a branching off, a little bit below the heart.

On the right atrium, the blood is entering from above. The arterioles and venules directly open into these spaces. The pericytes are non-contractile, phagocytic in function, and stimulate the endothelial cells to sprout for the growth of new capillaries.

Actually, the 20 seconds might be closer to the perfect route. By the elastic recoil the arteries convert the intermittent flow of blood from the heart into a continuous one. Some of these veins have varying nomenclatures present in the literature.

Human Arterial System Diagram

But what we have is, the heart pumps de-oxygenated blood from the right ventricle. If you just put syrup straight into water, what's going to happen? The venae comitantes help in the return of blood towards the heart by the transmitted pulsation of the arteries; probably they also help in counter-current heat exchange between arteries and veins.

De-oxygenated blood goes to the lungs to become oxygenated.

The Human Arterial And Venous System Diagram

To combat this blood flow problem, veins contain many one-way valves, which permit blood to flow only toward the heart. It is highest when the heart contracts and lowest when heart relaxes. The hepatic portal system extends from the capillary plexuses of the gut wall to the hepatic sinusoids.

This is a vein from the upper part of our body from our arms and heads. In the popliteal region posterior to the knee, the small saphenous, anterior tibial, and posterior tibial veins join with several smaller veins of the knee to form the popliteal vein.

The great saphenous vein ascends through the leg and thigh on the medial side, collecting blood from tissues in these regions. A correct diagnosis is important because people who have P.

Let's label it right here. From the right atrium, it gets pumped into the right ventricle. Atrium, you can imagine-- it's kind of a room with a skylight or that's open to the outside and in both of these cases, things are entering from above-- not sunlight, but blood is entering from above.

When the muscles relax, the valves prevent the blood from moving away from the heart. Clinical significance[ edit ] Diagram showing the effects of atherosclerosis on an artery.

Heart & Blood Vessels: Your Coronary Arteries

Arteriovenous Anastomosis Shunt Shunts of simple structure are found in the skin of nose, lips and external ear. The middle cardiac vein drains into the coronary sinus or directly into the right atrium [4].

The vessels generally drain into the coronary sinus. So this is the blood going away from the heart.Arterial anastomosis is the communication between the arteries, or branches of arteries.

It may be actual or potential. Actual Arterial Anastomosis: In actual arterial anastomosis the arteries meet end to. The Zygote 3D Female Circulatory System model includes the 3D heart model with interior and exterior, all major arterial flow and venous flow to and from the extremities, the visceral and reproductive organs, and to the heart and lungs.

Blood is a constantly circulating fluid providing the body with nutrition, oxygen, and waste removal. Blood is mostly liquid, with numerous cells and proteins suspended in it, making blood. Peripheral artery disease (P.A.D.) is a disease in which plaque builds up in the arteries that carry blood to your head, organs, and limbs.

Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. Human Circulatory System Diagram In terms of circulatory circuits three circulatory systems can be categorized namely coronary, pulmonary and systemic systems. However the components covering these circuits remain the same which are vessels, the pumping organ ‘ heart’ and circulating fluid ‘blood’, the types of circuit include.
