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.

When the blood pressure in a capillary exceeds the osmotic pressure in the capillary what is the net movement of fluid?

The movement should be OUTWARD toward the interstitial fluid. This is because the blood pressure is greater than the osmotic pressure (or more correctly the onconic/colloid pressure, since the membrane is actually quite permeable to ions but is not permeable to plasma proteins), and thus fluid (water and ions, along with other small molecules) can flow OUT of the capillary bed.

When you graze yourself you burst open lots of capillaries even so when you just cut one artery is more serious why?

so, that is because arteries have a more important job than capillaries do so they have more blood. also, they are more big whiles the capillaries can't almost be seen so it's not that serious.

Why are capillaries called thin walled vessels?

Unlike veins and arteries, capillaries are very small and very thin. While veins and the like have over 5 layers, capillaries only have two.

Why are capillary tubes good models for xylem vessels?

The capillary tube is continuous and unbroken (like the xylem), which is essential to the cohesion-tension theory. Both are also 'dead' and thin.

Are broken capillaries a symptom of alcoholism?

The liver is responsible for a few types of clotting factors and when the liver is diseased (which commonly is caused by alcoholism) it stops making these clotting factors and bleeding is more prevalent. A broken capillary, or a bruise, is a symptom of possible liver damage.

How does blood flow to the capillaries controlled with respect to meeting the bodies needs?

Examples: after a meal, blood supply to the digestive tract increases. During strenuous exercise, blood is diverted from the digestive tract and supplied more generously to skeletal muscles and skin.

How do you deal with Pressure at work?

Once you find out that you have high blood pressure, follow the guidelines that your doctor gives to you such as: eating less--especially of high caloric foods and more of fresh fruits and vegetables, take prescribed medicene if necessary, add exercise to your daily routine, get help with stressful situations if needed and slow down...

What is Starling's Law of the capillaries?

The hypothesis that fluid filtration through capillary membranes is dependent on the balance between the pressure the blood places on the membranes and the osmotic pressure of the membranes.

The law relating to the passage of fluid out of a capillary depending on the hydrostatic and osmotic pressures of the blood and the same pressures of tissue fluid, the net effect of the opposing pressures determining the direction and rate of flow.

Why is the swamp cooler leaking through the ceiling?

Check the float valve, all connections, and for holes [leaks in the water reservoir]. Another possibility is that the distribution tube[s] are poorly adjusted so that some water is sprayed through the netting, and/or the hose from the pump has a hole from which the water is spraying through the netting.j3h.

Can veins and arteries stretch the same distance as the world?

In an average person, all the blood vessels, veins, arteries, and capillaries lined up one to the other can go around the world at least twice.

How are arteries veins and capillaries like a system of highways and local roads?

arteries transport the blood away from the heart while veins transport the blood to the heart…….im thinking highways and local roads only go in one direction as do the arties and veins

What is the difference between blue and red capillaries?

They are not really red and blue. This is seen in preserved animals (and cadavers) and in drawings to show which are higher in oxygen (red) and lower (blue). In general, you also can see than veins are shown in blue and arteries are red.

What types of bleeding would be most detrimental to the patient?

Major Arterial bleeds are the most detrimental.

The reason is that while all major venal and arterial bleeds are exceedingly detrimental to the patient the Arterial bleed carries with it the additional risk of oxygen deprivation. A vein, whether major or minor, is essentially carrying waste for disposal and is akin to a sewer break. An artery however not only carries the same issues of blood pressure drop and possible build up of pressure on an internal bleed that a vein does but also deprives the organ or organs that the artery fed of precious oxygen which leads to the additional risk of tissue damage and tissue death with its attendant complications. This is why a heart attack is so deadly, because the loss of blood flow leads to the death of heart muscle, which then cascades into less ability to pump to itself and the rest of the body for instance.

In specific bleeds and Aortic rupture or bleed is the most detrimental. The Aorta is the main distribution artery for the entire body and a bleed there immediately impacts the brain, lungs, heart and all parts of the body.

Which is larger retinal arteries or retinal veins?

Retinal veins are larger than retinal arteries. Retinal veins are between 2/3 to 3/4 times larger than the arteries of the retina. Retinal vein are also darker red then the arteries.

Do teeth have capillaries?

The tooth roots (pulp, dentin, endodont) are living tissue and have capillaries as well as nerves. The outer enamel consists of tubes of dead material in which the nerves gradually die off as it grows outward, toward the surface of the tooth. The remaining nerves become evident when teeth are drilled, as in the repair of cavities.

How capillary thermostat works?

The capillary thermostat has a capillary tube which is usually filled with a refrigerant which usually contracts or expands due to temperature. As the temperature expands this liquid and in turn this pressure presses against a bellows that pushes against a switch , the switch closes and the refrigerator runs until the capillary cools enough to decrease the pressure and the opposite happens.

Why Auma MOV giving MWG defective and showing open and torque fault at tha same time?

HI,

1-MWG defective because of its setting which required after changing or install new MWG Transmitter assemble so you required for this higher level password.

2-MWG assembly not compatible or internal fault.
