Arteries

The external carotid artery is responsible for supplying blood the the face, jaw, scalp, and the base of the skull.

I think it is the cappilaries but those could be veins.

It is called the systolic blood pressure and is given by the higher of the two numbers on your blood pressure reading. eg, if your blood pressure is 120/80, the systolic pressure is 120mmHg.

The actual pressure follows a wave-form. As the ventricle contracts and squeeze blood into the arteries the pressure rises (from the lower diastolic level) and as contraction continues the pressure peaks and then drops back as the contraction finishes and the heart begins to relax. So to be specific the pressure will depend upon what phase of contraction one is referring to. However generally speaking it is the peak, as explained above, that is referred to.

they are the right and left ventricle

The coronary arteries.

There are two arteries in a persons wrist, almost on either side of the wrist. One is the radial artery, and ulnar artery is the other one.

The purpose of the femoral artery is to circulate blood around the thigh area as well as provide blood to the knees and feet. This process is critical as cells within the body require oxygen to survive and blood carries this oxygen to them.

Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet

Pulmonary arteries are those which take deoxygenated blood from the RIGHT VENTRICLE to the lungs through the ALVEOLUS back to the LEFT ATRIUM. The LEFT ATRIUM receives oxygenated blood from the lungs and is pumped by the heart to the LEFT VENTRICLE and then to the rest of the body.

It is ironic that Arteries do carry oxygenated blood but PULMONARY ARTERY carries deoxygenated blood and veins carry deoxygenated blood but the PULMONARY VEIN carries oxygenated blood.

Because it would block the blood flow and stop the heart.

It needs to distribute blood to the systemic circuit. For this reason it needs to be very large in order to distribute huge amounts of blood at once.

Haemorrhage can occur however surgeons take steps to prevent this from happening.

All exterior, mid and internal layers. We dont say hardening, better we call Reduction of elasticity of the arteries and arteroles, With ageing, changes occur, so there is shortage of elasin and collagen fibers in the endothelial layers

reduce the need for coronary bypass surgery.

No arteries do not contain valves since there is enough pressure from the heart to force blood through these vessels without significant backflow between contractions.

The first branches of the aorta are the coronary arteries, blocking them would cut supply to the heart.
