Capillaries
The smallest vessels in the circulatory system that are located within the tissues of the body, they transfer blood from the arteries, through the tissues to drop of nutrients and pick up waste and back to the veins.

What are arterioles and what are capillaries?
Arteioles are blood vessels that connect arteries and capillaries. Capillaries are blood vessels that connect arterioles and venules
The reason fluid leaves at the arterial end of the capillary bed and returns to the venous end of the capillary bed is the difference in hydrostatic pressure. This means the pressure against the inside of the vessel is greater that the pressure on the outside of the vessel on the arterial end and vice-versa on the venous end. Also, loss of water at the arterial end very slightly raises the oncotic pressure on the venous end, although to what degree this adds to the return of fluid to the vasculature is unknown.
Lymph capillaries are found in the?
They are found through out the body. They loosely follow the circulatory system.
Why does mercury fall downwards and water rise upwards when placed in a capillary tube?
Mercury is more dense than water.
For what purpose might one use capillary electrophoresis?
Capillary electrophoresis is a technique used in laboratories to separate molecules based on their charge in order to study and analyze them. Capillary electrophoresis uses an electric charge to force the movement of molecules since each molecule will go a varying distance based on the weight of the molecule and their charge. Some areas of study that use capillary electrophoresis include DNA sequencing and pharmaceutical analysis.
How thick is a capillary wall?
Capillaries are the smallest of all the blood vessels, they have extremely thin walls - just one cell thick. There are some spider-like cells (called pericytes) dotted along the outer wall of capillaries which help to stabilize them.
Which has more pressure arteries or capillaries?
Arteries, cause they are large vessels coming right from the pump of the heart (the left ventricle).
What are tiny blood vessels in which substances are exchanged between the blood and body cell?
The capillary is the only blood vessel where things can be exchanged because it is so thin (one cell thick). Capillaries have a single cell layer of squamous epithilium.
Do capillaries filter bacteria?
No. Capillaries are tiny blood vessels that carry blood to the cells of the body. They have nothing to do with bacteria.

Color of blood in the capillary?
Red or Blue depends if it is before of after the gas exchange. Is it bread or toast when it is in the toaster.
Describe two wys in which the structure of a capillary is adapted to its function?
Two ways in which the structure of a capillary is adapted to its function is to encourage the exchange of oxygen. Another reason is to encourage the exchange of carbon dioxide.

Can protein bound drugs pass easily through capillary walls?
Yes the proteins allow them to travel easily.
In the tiny capillary, interstitial fluid enters into the tissue, delivering nutrients, some white blood cells, and other various materials to the tissues. Red blood cells have a similar role, releasing oxygen and taking in carbon dioxide before entering the venule and beginning its journey to the heart once again.
The smallest blood vessels where the blood gets to interact with the bodies tissues.
What causes capillaries to burst on abdomen?
High blood pressure or diabetes can cause capillaries to burst in the abdomen. Trauma to the area can also cause this.

Yes, Diapedesis is a process by which "white blood cells" escape from the capillaries into the tissue spaces, but not RBCs and Platlets.
