Capillaries

Capillaries have slow flow. This slow speed maximizes opportunities of diffusion of oxygen, nutrients, and wastes.

No. The capillaries are part of the circulatory system.

Superior Vena Cava and the Inferior Vena Cava

alveoli

precapillary sphincters

Tubular secretion

Excessive squeezing will cause haemolysis of the sample, i.e., the rupture of red blood cells, thus releasing their content (Hb and electrolytes) into the plasma. Haemolysis will alter potassium, ionised calcium (ICa), phosphate and enzymes. If gross haemolysis occurs, all results may be affected, due to a dilution of the sample by dissolved haemoglobin.

Tissue fluid (resulting in increased potassium levels) may also contaminate the blood sample if you squeeze too hard.

Diapedesis

fossa ovalis is the wrong answer sorry for all who may have seen this here as the correct answer

the correct answer is the coronary arteries

As a metering device you need uniformity

Granulation Tissue

The resistance will increase

False, cartilage gets most of its nutrients via diffusion of nutrients from synovial fluid. The cells in the fibrous synovial membrane that produce synovial fluid are richly vascularized.

Most porous capillaries are present in glomerulous in a Bowmans capsule of nephron .They help in filtration of blood . Tortuous nature of capillaries also helps in filtration .

so that our poo has better texture

The great saphenous vein passes anteriorly to the medial malleolus. This vein is the longest in the body.

They bring them away from muscle tissue so that it can go to the lungs to be exhaled

Red blood cells have to pass through capillaries in a single file so the cells move fairly slowly. Because arteries have enough space to allow multiple red blood cells to pass side by side, blood flows fairly quickly. Therefore, blood moves more rapidly in arteries.

Carbon dioxide is produced as a waste product of respiration, and is taken in the bloodstream to the capillaries outside the lungs, where the CO2 diffuses into the alveoli of the lungs.

oxygen

They are involuntary muscles.

They are situated in between the arteries and veins. Since they are situated in between this two tissues they facilitate the exchange of substances between them.

They have thin walls .The thin walls allow them to quickly and easily allow substances to diffuse through or pass through them

They have a very narrow lumen. The narrow lumen encourages red blood cells to give up oxygen as they squeeze by body tissues

It is important because capillaries do most of their work of exchanging gases, oxygen and carbon dioxide, by diffusion, which works best under less pressure.

???That is not quite right. Exchange of gases occurs when there are different concentrations in a given sample and it has nothing to do with pressure. Filtration occurs under different pressure, diffusion happens regardless of pressure.

Dude write easier questions then people will answer.

The first capillary bed in the series is the glomerular capillary, where filtration occurs. The efferent arteriole on the distal end of the glomerular capillary. Objects it to the next capillary bed in the series: the peritubular capillary. This is where secretion and reabsorbtion take place. This type of system is an example of an arterial portal system.
