Human heart veins and arteries

Because the arteries arterioles and capillaries absorb most of the force of the hearts contractions veins and venules are subjected to very low blood pressures. Each of these plays a very specific role in the circulation process.

Human heart veins and arteries. Coronary arteries and cardiac veins. The heart is a muscular four-chambered organ that is responsible for distributing blood throughout the body. The continuous activity of the heart creates a large demand for nutrients to be delivered to cardiac tissue and for waste to be removed.

Veins are the large return vessels of the body and act as the blood return counterparts of arteries. Because the arteries arterioles and capillaries absorb most of the force of the hearts contractions veins and venules are subjected to very low blood pressures. Vena Cava is a large vein that returns blood from the head neck and extremities to the heart.

Superior Vena Cava is a large vein that carries blood from the head neck arms and chest to the heart. The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. The veins that flow into the coronary sinus include the great middle and small cardiac veins the left posterior ventricular vein and the left marginal vein.

Small anterior cardiac veins empty directly into the right atrium and the smallest cardiac veins drain into all four chambers but mostly the atria. These veins include the anterior cardiac veins which arise from the wall of the right ventricle and empty into the right atrium and the venae cordis minimae which are small veins in the heart walls that drain into the atriaIn the capillaries of the pulmonary vessels in the walls of the air sacs in the lungs is where the respiratory exchange of oxygen and carbon dioxide takes place figure 1020Figure 1020 Air sac artery and vein. One of the major differences between arteries and veins is that the arteries carry oxygenated blood to all body parts whereas veins carry the deoxygenated blood to the heart with the exception of pulmonary arteries and veins.

Left and right pulmonary arteries deoxygenated blood. Left and right pulmonary veins oxygenated blood. ClassificaonofArteries ElascArteries Conducngarteries AortaBrachiocephalic CommonCarod Subclavian VertebralPulmonaryCommon Iliac.

Posterior tibial vein. The pulmonary arteries and the pulmonary veins are the vessels of the pulmonary circulation. Which means they are responsible for carrying the oxygenated blood to the heart from the lungs and carrying the deoxygenated blood from the heart to the lungs.

The pulmonary circulation is different than systemic in context that within the pulmonary circulation veins carry oxygenated blood. The arteries red carry oxygen and nutrients away from your heart to your bodys tissues. The veins blue take oxygen-poor blood back to the heart.

Arteries begin with the aorta the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the bodys tissues. Arteries Veins and Capillaries.

The blood from the heart is carried through the body by a complex network of blood vessels see the figure below. Arteries take blood away from the heart. The main artery is the aorta that branches into major arteries that take blood to different limbs and organs.

On the other hand veins are defined as the vessels that carry deoxygenated blood from organs back to the heart. On the other hand capillaries are defined as the smallest vessels that link arteries and veins. Arteries carry blood to other organs of the body.

Veins help in supporting blood circulation. The ventricles are the chambers that pump blood and atrium are the chambers that receive blood. Among which both right atrium and ventricle make up the right heart and the left atrium and ventricle make up the left heart.

The structure of the heart also houses the biggest artery in.

An adults would be closer to 100000 miles long. There are three kinds of blood vessels. Arteries veins and capillaries.

Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. Theyre tough on the outside but they contain a smooth interior layer of epithelial cells that.

Arteries carry oxygenated blood from the heart to various body parts and body tissues whereas veins carry deoxygenated blood from various parts of the body and tissues to the heart to re-oxygenate. Their functions are associated with removing wastes from each body cell. Blood is transported in arteries veins and capillaries.

Blood is pumped from the heart in the arteries. It is returned to the heart in the veins. The capillaries connect the two types of blood.
