What would happen if heroin was injected into an artery instead of a vein?

It is not easy to do by accident, but when it happens YOU KNOW IT. Instead of a flash-back of dark red blood when you pull back to register your hit it will push the plunger back on it's own with bright red blood. IF you managed to push the dose in (remember the blood is going into your needle not away from it) your arm may blow up like a balloon. The rush is not even that much more intense. My recommendation is, do not even try this. Do not even think about it. It has destroyed many people already.

How does the carotid artery work?

The carotid artery is a major branch closely derived from the aorta; this artery provides the main blood supply to the tissues of the head, including the brain.

What is the difference between arteries and veins?

Veins are blood vessels carrying blood towards the heart, whereas arteries bring blood away from heart.

Mostly, arteries contain oxygenated blood, and veins contain carbon dioxide-rich and oxygen-poor blood; however, there is one exception. The artery leading to the lungs from the heart does not contain any oxygen, and the vein leading from the lungs to the heart does. This is so the oxygen from the lungs is brought to the heart in order for it to work. Everywhere else, the oxygenated vessels (arteries) carry blood to the rest of the body.

Histologically, veins have a large, floppy irregular lumen and a thinner wall. They also contain valves to prevent backflow when blood is being taken back up to the heart. Arteries usually have a round lumen and thick walls, but no valves.

Arteries generally have higher pressure and veins have lower pressure.

The blood in the veins is visibly less red than blood in your arteries, because the hemoglobin has been removed.

Why do arteries have the thickest walls?

Blood vessels are composed of three layers of tissue: tunica externa, tunica media, and tunica interna. The middle layer, tunica media, is composed of smooth muscle and is thickest in arteries because they need to accommodate the higher pressures created by the heart's pumping action which distributes blood throughout the body.

How does blood in the artery leaving the right ventricle differ from the blood in the artery leaving the left ventricle to where does the artery leaving the right ventricle carry blood?

The blood leaving the left ventricle is oxygen-rich and the blood coming out of the right ventricle is oxygen-poor. It then goes through the pulmonary arteries and into the capillaries of the lung where the carbon dioxide is exchanged for oxygen.

What color is oxygen-rich blood?

When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red. The more haemoglobin the blood contains the more oxygen is going to attach to the iron which is the most important element of the haemo-globin.

Can a vertebral artery be missing?

It would seem that might be the case as I just had an MRI of my brain and it looks like I am missing the distal vertebral artery. My neurologist is sending me back for an MRI of my neck just to confirm if this is really the case.

Yes it is possible to be missing one of your vertebral arteries. After years of suffering memory loss and migraines as well as multitudes of symptoms that never made sense and under going medication therapies that weren't necessary I have the answer. I am completely missing my left vertebral artery. This was found during an ultrasound of my neck, and confirmed with an angiogram. We still have no course of action to follow for this but I will keep you updated if they find any new way to fix this problem!

Why does the military use Julian date system?

The military uses the Julian date system for ease of calculating due dates of equipment inspections. For example, it is easier to just add 90 days to a Julian date rather than count out on 90 days on a calendar since most months have varying lengths.

What are the differences between an artery and a vein?

Arteries carry blood away from the heart to the other parts of the body. Arteries also have thicker walls as the blood pressure is much higher having a closer proximity to the heart. Veins carry the blood back from the other areas of the body to the heart.

Simply put, an artery carries blood out of the heart, and a vein carries blood into the heart.

How would depoits on the walls of arteries effect the flow of blood moving through the body?

Assuming depoits is deposits, if there are "deposits" in the arteries, it restricts the flow and depending on how thick the deposit is, very little blood gets through. Imagine a fireman using the usual hose to kill a fire. Then imagine that he replaces that hose with a garden, say about 5/8 thich. The same water pressure and the same amount of water is still there but very little water gets through.

Same with deposits. The chamber is smaller. Now you have all kinds of problems, not to mention high blood pressure, poor circulation, etc., etc., etc., etc.

What best describes the blood flow in an artery?

Hmm, that's an interesting question. The arteries suck the blood away from the heart. They both start with a's. If you wanted to be simple about the idea, you could say that the body is like a person sucking the blood through a straw (the arteries.).

What is the difference between an elastic artery and a muscular artery?

Elastic arteries or conducting arteries, are large vessels with diameters of up to 2.5 cm. They transport large volumes of blood away from the heart.

Muscular arteries, or distribution arteries, (also known as medium-sized), transport blood to the body's skeletal muscle and internal organs. It has a diameter of approximately 0.4 cm.

What is the function of the aorta?

The aorta branches into several different arteries which carry oxygenated blood from the heart to different parts of the body. The aorta is the artery that carries oxygenated blood from the left ventricle.

Because the aorta can stretch (expand), the pressure of the blood leaving the heart is more slowly and regularly transferred to the arteries. A pulse is still detectable in distant vessels, but the pressure is constant rather than intermittent.

All the arteries in the blood (except the pulmonary vein) can be traced back to a starting point somewhere along the aorta.

What is the medical term meaning abnormal narrowing of an artery or arteries?

Arteriostenosis is the medical term meaning abnormal narrowing of an artery. Normal, physiologic narrowing of an artery is called vasoconstriction.

Identify the parts and function of circulatory system?

Circulatory System parts and Functions

Heart- Pumps blood through the body

Arteries- Transports blood to the capillaries

Capillaries- distributes nutrients and oxygen

Veins- returns blood to the heart from the capillaries

Blood- is the liquid material that circulates throughout the body.It carries the nutrients to the cell.The blood delivers oxygen to the tissues.The blood also collects all waste products from all and brings them to the excretory system and other organs of excretion.
