Arteries are thick-walled blood vessels that carry oxygenated blood away from heart to various body parts.

What is the Function of the subclavian artery and vein?
The right subclavian artery extends from the brachiocephalic artery to the right side of the body. It supplies oxygenated blood to the arms.
What are the name of the main arteries and veins in the heart?
There are twenty main arteries, unfortunately. Some are:
- Carotid artery: runs up both sides of the neck and is the artery felt when taking a pulse from the neck, delivers blood to the brain.
- Femoral: runs through the middle of the thigh on both legs, delivers blood to the lower extremities above the elbow.
- Brachial: runs from the anterior of the shoulder to the elbow, delivers blood to the upper extremities.
- Radial and Ulnar: stems off of the brachial and goes around the radius and ulna respectively, feeds blood to the flangies and lower extremites below the elbow.

What is the normal value for a pulmonary wedge pressure?
Since there are no valves between the pulmonary capillaries and the left atrium, PCWP is a reflection of the LAP. During diastole, when mitral valve is open, the PCWP reflects LVEDP. LVEDP is an index of left ventricular end-diastolic volume. Here is a helpful URL to further clarify this entry. http://medind.nic.in/iad/t02/i4/iadt02i4p298.pdf
What is the scientific name for artery in the circulatory system?
The heart and blood vessels are part of the cardiovascular system. Cardio- or cardiac refer to the heart. Vascular refers to the blood vessels. Circulation or circulatory refers to the movement of blood through the vascular system.
What is Name of the largest artery in the body?
The aorta.It originates from the left ventricle of the heart and extends down to the abdomen, where it branches off into two smaller arteries (the common iliacs).
Is blood pressure the pressure of blood in the arteries?
Yes, blood pressure is a measure of the pressure exerted on your arterial walls as the heart pumps blood throughout the body (systolic) over the pressure when your heart is relaxed (diastolic).
What happens to the heart when an artery gets smaller?
You did not specify which artery. If it is one supplying the heart, it will affect the heart's efficiency. If it becomes completely clogged, part of the heart muscle will die unless the blockage is relieved.
If it is an artery to a limb or organ, the heart will have to work harder, and the amount of blood it can push through the artery will slowly become lessened. Eventually, there will be problems at the other end, and perhaps with the heart as well.
What is the function of the arteries in the circulatory system?
The function of arteries is to take blood from the heart to parts of the body.
There are two sets of arteries (relating to each side of the heart):-
- those that take blood from the heart to the lungs to be re-oxygenated; known as the pulmonary arteries. These are the only arteries that transport de-oxygenated blood.
- those that take blood from the heart to the rest of the body including the heart muscles so as to keep the heart going (known as the coronary arteries), to the brain (known as cerebral arteries) and all the muscles and skeleton. These arteries all transport oxygenated blood.
Because the blood is under pressure as it leaves the heart and because this pressure needs to be maintained to ensure that the blood reaches the extremities of the body, arteries have thick, muscular walls.
NOTE The function of veins is to return blood to the heart. Veins have thinner walls and have one way valves in them.
Why are veins darker in colour than arteries?
Veins are not actually darker than arteries. In fact, on dissection, veins and arteries are both a whitish color. The reason that they are more visible is because there are larger veins that are located closer to the surface of the skin than arteries. Veins also tend to have thinner walls, making the blood inside them more visible.
The main component of the tunica media of muscular arteries is?
Tunica Media or just Media is the central layer of arteries or veins. In the artery, it is composed of elastic tissue and smooth cell muscles.
What happens to your artery when you feel a pulse?
During diastole, or the resting part of the heartbeat, there is a minimum amount of pressure on arteries. When the heart pumps (systole) it forces the blood out of the ventricle and into the artery. Arteries are elastic, so when this blood passes through it, it causes the artery to expand from the increased pressure. It is this expansion as the bolus of blood rushes forward that you feel in a pulse.
Where does the blood that flows from the pulmonary arteries lead to?
The pulmonary arteries carry blood from the heart to the lungs.
What does aorta and vena cava do?
The Vena Cava carrys de oxygenated blood that is returning from the body and into the right atruim of the heart and the Aorta is the largest artery of the body which transports oxygenated blood to the rest of the body.Hope this helps.Shirley
How can you trace a drop of blood from the pulmonary artery to the right radial artery?
Why would you want to do that. You would have to cut open the heart and watch the blood move from the pulmonary artery through the heart and into the right radial artery.
Which artery connects heart to arm directly?
The coronary arteries are responsible for carrying oxygen-rich blood to the heart. However, most oxygen-rich blood is being carried away from the heart, meaning that most arteries are not carrying blood into the heart at all. Veins are responsible for carrying de-oxygenated blood towards the heart so that their oxygen supply can be replenished in the lungs.
The two veins which actually enter the heart are the superior vena cava or the precava which carries blood from the upper half of the body into the heart and the inferior vena cava(IVC), also known as the posterior vena cava, which carries blood from the lower half of the body into the heart.
What is renal artery it is clean or unclean?
Renal artery is that artery which connects the liver and the kidney.Its function is to transfer the primary urine produce in Liver to kidney for the further process of the primary urine to secondary urine.
What layer of an artery consists mostly of smooth muscle?
Arterial walls are more muscular than the walls of veins. This muscle is smooth involuntary muscle.
What is the artery leading into the lungs called?
The blood vessels that take oxygenated blood from the right ventricle to the lungs are the pulmonary artery. It is part of the pulmonary circulation.
Where does blood flow after the arteries?
From the arteries, the blood flows into the capillaries where food and oxygen diffuse through the one-cell-thick capillary walls and into the cells. Carbon dioxide and cellular wastes then diffuse into the blood. The capillaries then form veins. The veins then lead back to the heart so the blood can be sent to the lungs to be oxygenated. The blood is then pumped through the arteries to the rest of the body again.
Is the brachial artery an elastic or muscular artery?
I think the external carotid to be an elastic artery.
What is the function of the internal iliac artery?
Posterior Division:
Iliolumbar artery, lateral sacral artery, superior gluteal artery.
Anterior Division:
inferior gluteal artery, middle rectal artery, uterine artery, obturator artery, inferior vesical artery, superior vesical artery, obliterated umbilical artery, internal pudendal artery
What is the function of the muscular walls in the large arteries?
Basically what it does is protect the brain structure.
Coronary arteries supply blood to the?
The coronary artery supplies oxygen rich blood to the heart muscles. There are two main coronary arteries: the right coronary artery and the left coronary artery, However the coronary artery other parts that branch off and supply oxygen to the lower portion of the heart
What is the purpose of the coronary artery and what happens if there is a blockage?
Coronary artery bypass graft surgery (also called coronary artery bypass surgery [CABG] and bypass operation) is performed to restore blood flow to the heart. This relieves chest pain and ischemia, improves the patient's quality of life.
