Capillaries are very small in size because they need to have a large surface area so they are able to transport blood all around the body. Blood cells must pass in single file through the capillaries as they are so small.

Blood colloid osmotic pressure

you have 2 lungs. they are both located inside your rib cage, protected by the rib bones.

Alveoli. Singular is alveolus.

When the body is going through inflammation, yes.

Capillaries have very thin walls which are semi-permeable.

It serves the to return deoxygenated blood back to the heart

· Although similar to blood capillaries, lymphatic capillaries differ structurally in the following ways:

· The endothelial cells forming the walls of lymphatic capillaries are not tightly joined. Their edges loosely overlap one another, forming flaplike minivalves. The flaps, anchored by fine collagen fibers to surrounding structures, gape open when the fluid pressure is high in the interstitial space, allowing it to enter the lymphatic capillary.

· Bundles of fine filaments anchor the endothelial cells to surrounding structures so that any increase in interstitial fluid volume separates the cell flaps, exposing gaps in the wall rather than causing the lymphatic capillary to collapse.

In older pediatric patients 2-4 seconds can be considered "normal," but factors such as respiratory status and ambient temperature need to be considered in relation to these times as well. In neonates, because capillaries of the head and/or chest are sometimes used for assessment, different values appear in the literature. An upper limit of 3 seconds is a general guideline, but averages of roughly 2 seconds are considered "normal."

Although you may use water to help get sticky substances such as syrup off your hands, water itself is actually sticky. Water molecules not only stick to each other, but water also sticks to grass, cloth, organic tissues, soil, and paper towels. Plants take advantage of water's stickiness to organic tissues and soil. This movement occurs when the adhesion (the force that attracts the water to other objects) is stronger than the cohesion (the force between the water molecules). Water molecules are naturally attracted to each other. This attraction comes from the temporary hydrogen bonds that they form.

That would be the heart. The pulmonary vein carries oxygenated blood from the lungs to the heart's left ventricle, it then travels through the left atrium and out the aorta into the arteries and then the arterioles. It then enters the capillaries, here the oxygen diffuses into the cells of the body, and carbon dioxide diffused into the capillaries and bloodstream. The blood then continues to the veinoles, veins and back into the heart through the inferior or superior vena cava, into the right ventricle, right atrium and out through the pulmonary artery to collect oxygen from the lungs again. So starting from the beginning, the diagram of blood flow is as follows:

Lungs - pulmonary vein - left ventricle - left atrium - aorta - arteries - arterioles - capillaries - veinoles - veins - superior/inferior vena cava - right ventricle - right atrium - pulmonary artery. And the cycle continues :)

A human hair has an average diameter of 70 mikrometers and a capillary has an average diameter of 7 mikrometers, so that tells us that 1 hair takes about 10 capillaries in width.

You probably have a deviated spetum bleed often caused my using massive amounts of Cocaine.

Whoever wrote the above answer obviously isn't a doctor because I have never used Cocaine a day in my life and I sneezed a small amount of blood this morning.

Yes, because as you get older your heart also gets older and can't function as well.

CO2 and O2

Generally the blood pressure at arterial end of the capillaries is about 30 mm of mercury. The blood pressure at the venous end of the capillaries is about 15 mm of mercury. The fluid exit the capillaries at arterial end. Fluid enters the capillaries at venous end.

The purpose of a Capillary Tube is to

allow blood to complete a path between arteries and veins

permit oxygen and nutrients to be absorbed by cells

and provide a means for cell wastes to enter the blood stream
