Why is a tube of blood clogged up?
It is an everyday occurrence, and it is not just a concern for patients in intensive care.
In fact, many doctors say it’s a major problem for the entire healthcare system.
But what does the tube really look like?
A tube of fresh blood.
The tube is called a venous catheter, and is used to deliver blood to a patient’s heart, lungs or other organs.
It is also known as a bleeding catheter.
The tube has two ends, which are usually about 1cm apart.
These ends are used to carry blood to the other end of the tube.
They are usually attached to a needle or an applicator, which is attached to the tube, and the blood is passed through a small tube in between them.
The blood is then drawn out through a needle at the other side of the catheter.

But a blood clot could form on the other one, and this can cause a problem.
If a clot forms on one end of a tube, it is known as an infantile myocardial infarction (IHF).
This is a rare and potentially life-threatening condition.
Most people who have an IHF are able to avoid needing to have a blood transfusion, because they can avoid bleeding from the other.
But if there is a clot on the tube on one side, then there is an increased risk of a stroke, which can cause severe and life-changing brain damage.
Clotting occurs when there is more than a certain amount of blood circulating through the body.
This is a risk factor for other complications, including heart disease and stroke.
In most cases, the clot has to be removed from the tube to be fixed.
But if it does not, the tube will continue to drain blood through the wall of the vein, so it is sometimes called a “bleeding catheter”.
It drains blood to different parts of the body, including the heart and lungs.
There are two types of blood vessels: a deep one that carries oxygen and nutrients from the blood to cells in the body; and a superficial one that is filled with water and nutrients that allow cells to survive.
What can cause blood clots?
Blood vessels are very simple to build and can form in a variety of places.
They consist of three main parts: a blood vessel that is at the top of the blood vessel, and a blood vessels muscle that stretches between the two sides of the artery.
A large blood vessel is one that holds a lot of blood.
A small blood vessel holds less blood.
These vessels form when the blood supply to a body’s cells is low.
When the supply to the cells is high, the blood vessels are used for transporting nutrients from blood cells to other cells, like the cells in your brain.
The result is a blood supply that is less efficient and may cause a blood clot to form.
The biggest risk is when the clot forms inside the blood tube, where it is blocked by a small blood clot in the veins of the arteries that supply blood to your heart.
Sometimes the clot will get into the blood stream from a nearby artery, called the coronary artery, and block it.
This causes the blood pressure to increase, and blood vessels can become swollen and clogged.
This may cause blood to leak from the blocked artery into the bloodstream, which may be fatal.
Another risk is the buildup of a blood-thinning condition called thrombocytopenia, which occurs when the thrombus, a thin, blood-carrying vessel in the blood, becomes too thick to allow the blood through.
When this happens, the clots cause blood vessels in the heart to stop pumping, causing your heart to beat slower and faster.
Why are blood vessels blocked in the brain?
The blood vessels that are normally the main source of blood to neurons are blocked in your heart and other parts of your body.
This happens when blood flows through the blood clot from the arterial veins, which carries oxygen, nutrients and the nutrients necessary for cell growth.
However, there are some things that can happen when this supply is not enough, and these can result in the clogging of blood vessel walls in the arteries.
When this occurs, the arterioles can start to dilate.
This can cause the blood that comes out of the vessels to become blocked, and that can cause blockage to the blood flow in other parts in the vessels, which in turn causes the arteries to become narrowed and blockage of the flow of blood through them.
In rare cases, there is also a condition called chronic vasculitis, which causes a condition known as arterial vasculopathy, or AV.
AV can lead to narrowing of the arterio-
