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 happens to oxygen at the pulmonary capillaries?

The blood returning to the heart after delivering its load of oxygen is deoxygenated, but it is still carrying 75% of its full capacity. When this deoxygentated blood is pumped to the lungs and into the pulmonary capillaries, it meets oxygen rich air that has been inhaled. And, in tiny sacks called alveoli, the gas exchange occurs where carbon-dioxide is diffused into the air in the alveoli, and the oxygen is replenished back to 100% capacity so it can be pumped throughout the body tissues.

How do capillaries relate to veins and arteries and what happens to the capillaries?

If you imagine your right arm as an artery and your left arm as a vein, then clasp your fingers together gently and imagine this is a capillary bed. Arterioles and venules come together in capillary beds and as oxygen is exchanged to surrounding tissue the blood from arteries is passed through the arterioles, through the venules and into the veins to return to the heart.

What causes red capillaries to burst on ankles?

CVI chronic venous Insufficiency also called spider veins, or Telangiectasias-can be caused by developmental abnormalities. This is often treated with laser or IPL therapy. There have been medication based treatments available for over 50 years. A Sclerosant medication is injected into the diseased vein so it hardens and eventually shrinks away.

What does the pulmonary capillaries do?

The blood cells carry carbon dioxide to the lungs which, through the mechanism of breathing, gaseous exchange takes place with the carbon dioxide leaving the body while someone breathes out. When they breathe in again, the blood cells in the pulmonary capillaries get loaded with oxygen and the new oxygen rich blood goes to the heart to be sent around the body.

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.

Why are there so many capillaries in your bodies?

There are so many capillaries in our bodies so the blood can circulate fully around the body. The blood carries oxygen to our cells, and the capillaries carry around the blood to the hard to reach places, such as the tips of our fingers and the tips of our toes. When you cut of the circulation, or the blood flow, in your finger, and you get a bruise, this is because the capillaries have broken open. Without the capillaries, our cells would die from no circulation. Capillaries are very important for the Healthiness of our bodies.

What are broken capillaries?

Broken capillaries are commonly found on the cheeks or nose area these appear as small red / pink threads under the skins surface, most. Broken capillaries occur when the capillary walls narrow and widen too quickly causing the muscles int he walls to tear. This in turn allows the blood to seep out resulting in broken capillaries.

Dehydrated, dry and sensitive skins often have thin skin that provides less protection and therefore, these skin types are the most commonly effected.

Common causesof broken capillaries are:

1. Hot conditions

2. Wind blowing on the face

3. Burnign i.e. sunburn

4. Moving from one extreme temperature to another

5. Pressure i.e. squeezing spots or glasses pressing on the face

Broken capillaries can be prevented by avoiding all of the above. Once formed they can be treated by a specialist form of electrolysis. There are also specialist creams on the market that aim to strengthen the capillary walls thus reducing the redness.

In pyrometallurgical refining what is the driving force behind selective oxidation?

When we set up to win metal in a recovery operation, we frequently choose to remove other materials by simply applying heat to "burn off" or oxidize the things we don't want in our end product. Let's go at this query in two parts. The first part is a no brainer. It's pyrometallurgical refining - we apply heat (fire - the "pyro" part) to a stream of influent to effect the oxidation of stuff we don't want in our desired product. Melt it, blow oxygen through it, burn off dross and presto! good product. Piece of cake. Just burn it off. Remove it by oxidation. But how? Why selectively, or course. Let's look at the "selective" part of oxidation. We need a clear knowledge the "contaminants" in our product stream, their identities and their concentrations. We call the lab folks in off their coffee break and have them find out. Then we weigh these nice folks down with another problem. What is the chemistry of our desired metal and also all of these "contaminants" in our initial product? Everything! And not their "regular" chemistry. We need to know their chemistry at elevated temperatures. In addition, we need to know how all the "contaminants" and our desired metal react with each other (in those proportions calculated in our influent stream) at elevated temperatures. (We don't do that stuff. We're engineers! So we're drinking coffee and filling in crosswords and a sudoku or two while they bust their buns in the lab.) They come back with the data. And the secret to the "selective" part of our "selective oxidation" process. Break is over for us. We grab our hard hats and face shields. The metallurgical chemists have given us a "cook book" to cook up our influent and guide us in winning the desired metal. What happens is that we heat everything up to the "required temperature" per out cook book, and then we add "secret ingredients" to the mix. The material(s) stirred into the molten mix are specifically chosen because they will react with our "undesired materials" and minimally impact our desired metal. The addition of specific materials in specific amounts is the key to making things happen. We force oxygen through the mixture, and the selective oxidation of the dross will occur per our "recipe" courtesy of the guys and gals back in the lab. With the slipping quality of materials in our influent stream (decreasing quality of scrap in the recycling process, lower quality ore - that kind of thing) this process is becoming increasingly important. When calculating costs to recover metals, we see that an already high energy bill will continue to creep up. Energy is increasingly expensive. If there is anything we can do to improve our processes and control our costs, we need to incorporate it. High temperature chemistry acting on a mixture that has had selected materials in controlled amounts added to a molten "base" mix that is then blasted with oxygen is the driving force behind selective oxidation. The application of heat to a mixture and mixing in specific ingredients in specific amounts followed by a big blast of oxygen through the mix to effect specific oxidation of is not new. But its importance in metallurgical recovery processes is now, more than ever, critical to metal markets (and, ultimately, the consumer).

Where does oxygen enter the capillaries?

In the Lungs capillaries switch out oxygen when you hale in, and give CO2 back, which you exhale. From your Lungs oxygen runs trough your whole body. (in the blood)

What would happen if you didnt have capillaries?

If we didn't have capillaries, we would die. This is because CAPILLARIES are the passageways between the arteries (carrying oxygen- rich blood AWAY from the heart) and the Veins (carrying oxygen- poor blood back INto the heart). Capillaries come in close contact with the body's organs. They exchange their oxygen- rich blood (provided by the arteries) with the organ's oxygen- poor blood (containing carbon dioxide). Thus, the body's organ supply of oxygen- rich blood is replenished. Then, the capillaries give their oxygen- poor blood (from the organs) to the Veins, which bring the blood back to the heart, so it can be filled with oxygen again. It's all a big cycle, and our capillaries play a big role in this cycle. The heart, blood, and blood vessels (arteries, veins, and CAPILLARIES) are all a part of the amazing Cardiovascular System! (Also known as Circulatory system) We really need those Capillaries !! So... What would happen, you ask? Well, the blood in the arteries an the blood in the veins would mix. That is very bad. Our body could not survive if oxygen-rich blood and oxygen- poor blood mixed. We have the capillaries to ensure they never interact!!
