The red fluid that circulates through your body is your blood. It keeps all your body functioning properly, and actually it is not red until it is exposed to oxygen.

VEINS

Bone is built around the blood vessels that supply it ...

and if the blood supply changes then the bone structure is modified to fit.

Bone is NOT static, unliving stuff, it's a part of the system that makes up you.

Angiography; radiographic imaging of the heart and blood vessels after injection of a contrast dye

Artery, arterioles, veins, veniouls and cappilierys

Baroreceptors

Mucus traps foreign particles as it enters the conducting parts of the respiratory system. Cilia are microstructures lining the epithelial layer of those conducting parts that act to sweep up the mucus-bound foreign particles that otherwise would enter the lungs.

Blood pressure is the measure of the pressure created as the heart pumps blood through the blood vessels. This is one of the most important vital signs.

Left Atrium. Chamber that receives oxygenated blood from the pulmonary veins and pumps it into systemic circulation. Superior Vena Cava. Carries (drains) blood from the head, neck, and upper limbs and empties in the right atrium.

it is not absorbed because of dead cells, or pathogen!

The gonadal artery which leaves the aorta directly at the level of L2. Some references will calles this the ovarian artery in women and the testicular artery in men but for the sake of simplicity the gonadal artery is perfectly adequate.

Blood capillaries

antidepressants and smoking

muscles, bone , organs, glands, nerves, membranes, other useful fluids and mucus contained in skin. then there air water, cars, other peoples veins and blood, fluffy rabbits, earth, moon sun , galaxies and then nobody is really quiet sure yet what's outside of that.

Every thing is outside the vein except the veins.

Veins don't pop inside your fingers. When you crack your fingers it makes a popping sound, this is when you push a joint in your finger and the bones pull apart and the pressure on the synovial fluid is reduced, bubbles form and quickly expand then burst making a pop sound.

Veins. The inner layer of veins (the tunica intima or tunic interna) forms valves to reduce backflow because. Veins have lower blood pressure than arteries and are often fighting against gravity, so the prevention of backflow is essential.

Capillaries

Dilation of a blood vessel is the term for physiologic widening of the vessel. Abnormal widening of the blood vessel through a weakening of the wall is known as aneurysm.

Dilation of a blood vessel means widening of the vessel.

So a heart-attack is a result of a block artery. This blockage can prevent blood flow to the muscle of the heart. If this is the case, the muscle ca become damaged.

So to answer your question, the vessels are not necessarily getting damaged during a heart attack. It's the muscle. However there are three vessel the supply the heart with blood. Below is each vessel and the muscle wall that could be damage in a heart-attack.

Right Coronary Artery(RCA): Inferior wall

Left Anterior Descending (LAD): Anterior Wall

Curcumflex(Cx): Lateral wall
