What is the pattern of arteriovenous distribution

1 Distribution law outside the organ: basic symmetrical distribution on the left and right The arteries of the trunk trunk are divided into parietal branches and visceral branches Arteries are often accompanied by veins and nerves to form nerve bundles There is an arterial trunk in each part of the human body Most arterial truncus is located on the flexor, deep and hidden parts of the body Arteries often reach the organs in which they are distributed at the shortest distance The form of arterial distribution is related to the morphology of the organ The caliber of the artery is sometimes not completely determined by the size of the organ it supplies blood 2 The distribution law in the organ: The artery of the solid organ often penetrates through its depression Organ arteries with lobulated structures enter hollow or tubular organs from the "gate", and the arteries are distributed in a divergent, transverse, or total row pattern.

Veins don't have a regular distribution, right......I'm sorry I didn't learn.

Hello answer, glad to answer your questions. Arteries and veins are part of the body's circulatory system, and their main function is to transport blood to the heart, lungs, and other tissues and organs of the body. Although the main function of arteries and veins is to transport blood, arteries and veins are very different.

Arteries carry blood from the heart to other tissues and organs, while veins carry blood from other tissues and organs back to the heart. The blood inside the arteries contains a lot of oxygen, while the blood inside the veins contains a lot of carbon dioxide. Arterial blood is bright red, while venous blood is dark red.

Arteries: Arteries are blood vessels that start from the heart, branch out more and more, and finally end in the capillaries of other tissues and organs of the human body. The lumen cross-section of the artery is usually round, the wall of the artery is relatively thick, and the artery has more elastic fibers and smooth muscle, so the arterial elasticity is better.

The pressure inside the arteries is relatively high, so the blood flows faster. Arteries are mainly found in the deep parts of the body.

Veins: Veins start in capillaries, converge into large veins, and end in the heart. The lumen cross-section of the vein is usually oval, and the wall of the vein is relatively thin, because the elasticity of the vein is relatively poor because of the lack of elastic fibers and smooth muscle.

Veins are mostly subcutaneous. In addition, there are venous valves on the vein wall that prevent blood from flowing back. Usually, blood draws and infusions are done through veins.

Arteries carry oxygenated blood from the heart to all parts of the body.

Veins carry oxygen-deprived blood back to the heart. Arteriovenous crossings are distributed throughout the body. Hope it helps.

Arteries are blood vessels that carry blood out of the heart, and after emitting from the ventricles, they branch out repeatedly, becoming thinner and thinner, and finally migrate to the capillaries. Arterial walls are thicker and can withstand greater pressure. The wall of the aortic artery has more elastic fibers and greater elasticity, and the wall of the canal expands during ventricular ejection and retracts during ventricular diastole, so that the blood continues to flow forward.

Veins carry blood back to the blood vessels of the heart. The blood in the veins contains more carbon dioxide, and the blood is dark red. Veins are the tubes in the cardiovascular system that direct blood back to the heart.

Veins begin in capillaries and terminate in the atrium. The venules originate in the capillaries and gradually merge into the middle vein, the large vein, and finally inject into the atrium. The venous wall is thin, the smooth muscle and elastic fibers are less, the contractility and elasticity are lacking, and the lumen section is flat.

In addition to cornea, hair, nails, dentin and epithelium, blood vessels are all over the body.

Arteries originate from the heart, continue to branch, the caliber becomes tapered, the wall gradually thins, and finally divides into a large number of capillaries, which are distributed to various tissues and cells throughout the body. The capillaries rejoin, progressively forming veins and finally returning to the heart.

Arteries and veins are the pipes that carry blood, capillaries are the places where blood and tissues exchange substances, arteries and veins are connected through the heart, and blood vessels throughout the body form closed pipes.

Hello, there are arteries and veins all over the body! In addition, the drawings have detailed locations and names.

In the figure; The blue bar is the vein and the red bar is the artery. s6

Just look for a distribution map online.

It's good to buy a map of the distribution of the meridians of the human body.

Arteries are generally deeper than veins, and veins are generally on the surface of the body, with thicker walls of arteries, more annular muscles, better elasticity, and some arteries even have automatic beating rhythms

In general, the distribution of external arteries has the following rules:

The cloth is adapted to the structure of the human body.

There are 1 2 truncus arteriosus in each large area.

It is divided into parietal branches and visceral branches, and the parietal branches retain the original segmented state.

Arteries are often accompanied by veins and nerves, constituting vascular nerve bundles.

During the trip, it is mostly located on the flexor side, deep part of the body, or in a safe and hidden part.

It often reaches the organs where it is distributed at the shortest distance.

The form of distribution is related to the morphology of the organ.

The caliber is related to the size of the organ it supplies blood and the function of that organ.

Characteristics of veins: large number, large lumen, thin wall, small elasticity, slow blood flow.

Venous valves. Systemic veins.

The superficial veins (subcutaneous veins) are finally injected into the deep veins.

Deep veins (concomitant veins).

The name and itinerary are the same as those of the companion lineage.

The anastomosis of the veins is more abundant.
