Arteries

Although it is an arguable topic whether blood is ever truly blue at one point or not, we'll just go along with the common lesson that "blue blood" is blood that is not oxygen-rich. This blue blood is carried in the pulmonary artery, where it is taken to the lungs in order to obtain oxygen, where it is then sent back to the heart, then sent to the rest of the body.

some times , after angiography the doctors says,this patient have two clogged arteries or three clogged arteries.My question,total how many arteries in normal human heart.and how many clogged arteries will lead the patient to death?

Arteries carry blood to all parts of the body.

Bigger volume means less pressure on the sides, so pieces of junk can stick easier, rather than being blasted through in the small vessels.

There is no simple method of observation for vein or atery bleeding. A safe assuming however, is if there is profuse amount at an excessive rate of blood leaving the victim's body they have a severed artery. If this is the case, they will likely die before an ambulance arrives. In either situation, pressure should be applied between the heart and the wound to slow the rate of blood loss.

The branches from arteries are arterioles and then into capillaries.

Oxygenated blood leaves the left side of the heart through the aorta,the largest artery and then to smaller arteries.Deoxygenated blood leaves the right side of the heart through the pulmonary artery then to arterioles and capillaries.

Yes, because there is more pressure in the artery than in the vein so the artery has to be big enough to hold the pressure that's inside it.

the color of aorta isRed. In the veins, its a deep maroon.

The pulmonary arteries carry deoxygenated (O2-poor) blood from the heart to the lungs so the blood can be oxygenated. Remember that arteries and veins are not defined based on whether they carry O2-rich or O2-poor blood but rather the direction they carry blood. Arteries carry blood away from the heart and veins carry blood back to the heart.

Coarctation of the aorta and Aortic Stenosis both describe narrowing of the aorta.
Narrowing of the aorta is called Aortic Stenosis. Commonly caused by plaque buildup known as atherosclerosis.

This comes from my A&P lab manual... "In the armpit, the subclavian artery becomes the axillary artery, which serves the upper limb." The previous answer was "brachial," which could also be a correct answer. "The brachial artery divides into the radial and ulnar arteries, which follow the same-named bones to supply the forearm and hand."

Another name for atherosclerosis is "hardening of the arteries." LDL or "bad cholesterol" is the raw material of cholesterol plaques.

Arteries Cary oxygenated blood. This is usually to organs or muscles with the exception of the pulmonary artery wich carries oxygenated blood from the lungs to the heart.

Because it have a pressure it must pump the blood and carry it away from the heart

Capillaries, they are the smallest of a body's blood vessels and part of the microcirculation. Capillaries are 5-10 μm in diameter and connect arterioles and venules and enable the exchange of water, oxygen, carbon dioxide, nutrients and waste chemical substances between blood and surrounding tissues.

Coronary heart disease refers to the failure of coronary circulation to supply adequate circulation to cardiac muscle and surrounding tissue. Coronary heart disease is the most common form of disease affecting the heart and an important cause of premature death. It's predicted that coronary heart disease will affect all the regions of the world by 2020.

The arteries are the vessels that lead from the heart. When the heart sqeezes (beats) the blood is forced out into the arteries causing an increase in pressure. This pressure increase is what you feel as the pulse. The blood must travel through the body, into the capillaries and into the veins. By the time the blood has traveled that distance, much of it's initial pressure has declined.

In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle. It is short and wide - approximately 5 cm (2 inches) in length and 3 cm (1.2 inches) in diameter. It then branches into two pulmonary arteries (left and right), which deliver deoxygenated blood to the corresponding lung.

Main reason is genetic and bad life style, final result in arterioles is Calcification along with other minerals and waste materials of the metabolism; (hardening or loosing the elasticity and clogging) of the coroner (heart) arteriole's' (The blood vessels that supply blood for heart it self) especially inner walls.

The mesenteric arteries go to the mesentery. The mesentery is a fold of the peritoneum that pins the stomach, small intestine, pancreas, spleen, and other organs to the posterior wall (back wall) of the abdomen.

Carotid endarterectomy is the process to remove the plaque on the lining of a clogged carotid artery.

coarctation of the aorta

Several arteries are used as pulse points including:

The radial artery (Lat.: A. Radialis) on the underside of a persons wrist is often used, because of its easy accessibility.

The femoral artery (Lat.: A. Femoralis) is also, although rarely, used.

The jugular artery (Lat.: A. Carotis communis) is often used.

Two other rather important pulse points are located in the feet:

The dorsal artery (Lat.: A. dorsalis pedis aka. A. Tibialis Ant.) and the posterior tibial artery (A. Tibialis post.).

The radial artery is without question the most often used pulse point. Regarding the systolic blood-pressure in critically ill patients the following rule of thumb is observed:

No pulsation in the radial artery, but pulsation in both femoral and jugular => Systolic pressure of ~80 mmHg.

No pulsation in either the radial nor femoral, but pulsation in jugular => Systolic pressure of ~70 mmHg.

No pulsation in either of the three points => Systolic pressure of ~60 mmHg. This is rarely observed.

The two points located on the foot of a patient are often used to assess vascular conditions in this area. This is often relevant after trauma of the leg and/or foot.

It should be noted, that in healthy individuals, the dorsalis pedis, posterior tibial and femoral pulses are impalpable in ~8 %, ~3% and 0 % of the time respectively.

When assessing the pulse, you check for:

- quality

- rate

- rhythm

- amplitude

Note should also be given to the fact, that the brachial artery (Lat.: A. brachialis) is quite often used as the artery for blood-pressure measurement.
