Arteries

Internal carotid artey passes through the carotid canal and takes blood to the brain

Because arteries have to do with giving blood to body parts and blood pressure has to do with the amount of blood you have and the arteries have a huge part in that!!!

Thank you

arteries are the carriers of oygenated blood to the body . blood pressue is very high. the walls are made of elstic material which can either contract or dilate due to pressure changes. blood pressure levels can be influenced by exercise ie when muscles are in motion and temperature changes

You will die, point blank. You need a healthy aorta in order to carry oxygenated blood through the body. Without your aorta you would have blue blood in your ENTIRE body, and that's not healthy, nor is it safe for any human.

It is stopped because the artery is stopped from pushing the blood forward.

Radial arteries for each arm,

but each finger as a pair of digital arteries.

It depends on which artery. If your femoral artery is severed, you have minutes to live without immediate medical attention. Same for the Carotid artery in your neck, or the jugular vein in your neck. If the aorta artery feeding your heart goes, same thing. I would say the smaller the artery, the longer you may have to live before you bleed out.

The biggest life threat as far as arterial bleeds is the aorta. If any part of the aorta ruptures, a surgeon couldn't save you if he already had you cut open on the table. Essentially, if the aorta ruptures, it will only take about 3 beats of the heart to bleed out. The further away from the heart you get, the slower the bleed will be, but any compromised artery is potentially life threatening. The femoral artery in the thigh (the femur is the thigh bone, hence the name fermoral) is another big bleeder. The carotid is the second biggest life threat if it's compromised. So basically, if the aorta ruptures, 3 heart beats. If the carotid ruptures, perhaps 2 minutes. If the femoral is severed, perhaps 5 minutes. The difference is that the carotid and the femoral arteries can be controlled with proper treatment. The aorta is untreatable once it's compromised.

Atherosclerosis occurs when LDL (Low Density Lipoproteins) get oxidized. Since the plasma in the arteries contains plenty of oxygen to oxidize the LDL's it occurs mostly in arteries. In the veins, there is little oxygen to be found, so it is much more likely to happen in the arteries for that reason.

The most common ailment of the circulatory system is atherosclerosis, or hardening of the arteries. This condition can lead to heart attack or stroke. Sometimes there are no symptoms, but when the problem is severe it typically causes symptoms such as chest pain, shortness of breath, weakness, nausea, and sweating. The second most common circulatory disease is hypertension, or high blood pressure. High blood pressure is very often without symptoms and has been called 'the silent killer', so it is important to get regular blood pressure checks.

Here is how it works.
You breathe in oxygen, the blood around your lungs picks up that oxygen and goes to your heart (left part) which pumps it to your entire body.
As the blood gives oxygen to your tissues, your tissues give carbon dioxide in return because it is a waste product that you need to get rid of.
This blood then returns to your heart (the right part) so that it would be pumped back to the lungs where it gives off the carbon dioxide (which is exhaled by your lungs) and takes a new dose of oxygen so the cycle begins again.

Therefore your heart functions in 2 ways simultaneously, it pumps blood that has oxygen to your body, and blood that has no oxygen (but has carbon dioxide) to your lungs.

Arteries, becuase they are directly pumped by the heart while veins are pumped some by your heart and some by muscle movement.

Arteries have thicker walls as well to cope with the greater pressure.

the left ventricle

the descending arota receives blood from the arotic arch/ ascending arota.

Trace a drop of blood from the left knee to the right arm

As the Circulatory System is a closed system, it has no beginning or end. Therefore the blood is in continuous circulation.

My husband had one done today. I am not 100% positive how to explain it, but the way I got it, it was like a sonogram. They use the same ultrasound machine they use when you are pregnant. The only difference is they are checking the blood flow in you legs. For my husband they were checking for a blood clot in his leg and thankfully that was not the cause of his inflamation and pain.

The seller is responsible for all of the real estate commission regardless of whether the transaction involves carrybacks. Regardless of the financing, the seller is always responsible for the realtor fees.

The first thing that will happen is that the vein in question (jugular) would begin to rapidly hemorrhage (bleed) at a rate of 700mL per minute if the victim is lying down, or at a rate of 70mL per minute if the victim's head is at a right angle. The victim will then go unconscious, or if left untreated, will become brain-dead and be declared clinically dead.

The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.

Absolutely. Peripheral vascular disease (atherosclerosis or inflammation of peripheral blood vessels, such as those in the leg) can diminish blood flow to the leg muscles, which causes pain known as claudication. It is very common--I forget the exact statistic but something like 20% of Americans older than 65 have PVD. Initially it presents as pain that comes with walking a fixed distance but gradually progresses to pain at rest. If you are a smoker, then the single most easily modifiable risk factor is to stop smoking. If you are having pain like this, then you need to see a doctor. A doctor will be able to determine whether the pain is from vascular disease, or from another cause (like spinal stenosis). More importantly, if you do have PVD, a doctor will also be able to evaluate you for heart disease, hypertension, dyslipidemia, and diabetes, which are dangerous but treatable, and commonly associated with PVD.

Your right side of the heart pumps blood in the pulmonary circulation. The pulmonary circulation should start from the origin of the pulmonary aorta.

Cholesterol plaque may slowly build up in the carotid artery wall, over decades.

LAD

To travel from the aorta to the left, or right, occipital lobe, it would have to go through the aortic arch, common carotid artery, external carotid artery, then occipital artery.
