Blood

blood carries oxygen around the body, so the blood gets the oxygen it needs to carry from the lungs, the b lood then returns to the heart which pumps all the blood with oxygen throughout the body. the blood without oxygen is pumped to the lungs to gain oxygen first!

The blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain. Three cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs). Tight junctions (TJs), present between the cerebral endothelial cells, form a diffusion barrier, which selectively excludes most blood-borne substances from entering the brain. Astrocytic end-feet tightly ensheath the vessel wall and appear to be critical for the induction and maintenance of the TJ barrier, but astrocytes are not believed to have a barrier function in the mammalian brain.

No, human blood is red - the shade may differ at the various stages of the circulatory system, but ultimately you do not have blue blood.

The misconception comes from the color you see when you look at your veins. The light is refracted differently when it passes through your skin causing a bluish color. In addition, deoxygenated blood will look dark red, but never blue. Blood in veins is deoxygenated because it is flowing from tissues where oxygen was dropped off, and will then flow to the heart and lungs where it will become oxygenated and bright red.

Often times in Biology and other science textbooks, the path of oxygenated and deoxygenated blood in the circulatory system is illustrated by blue and red blood. This is solely to show clearly where blood is on its way to tissues to drop off oxygen and where blood is making its way back to the heart for the pulmonary circuit. Do not be confused and assume that deoxygenated blood is blue; it is that way in textbooks for visual illustration purposes.
No. Blood is red in colour. Veins close to the skin may look bluish.

Blood is always red, whether it is oxygenated or not. It is a myth that blood turns red when exposed to oxygen.

high hlood and Diabetes makes your blood thicken

Alcohol generally lowers a type I diabetic's blood sugar.

Answer: This is not necessarily true. if the alcohol your drinking has alot of sugar in it, it is dangerouse for type 2 diabetics as their blood sugar will rise too much and they may go into a diabetic ketoacidosis, basically a coma. If a type one has alcohol, they will need to make sure they have had a meal before hand, and type one's usually suffer from low blood sugar so they will need to be careful as a low blood sugar is worse than a high one.

No. 443 platelet count is medical-speak for 443,000 platelets in a cubic millimeter of blood-- and normal is generally considered between 150,000 and 400,000/mm3. Having a slightly elevated platelet count is not a big deal.

Hemoglobin is found in all mammals and in some vertebrates. The following is for mammals only.

Our DNA (Deoxyribonucleic acid) carries the blueprints for Hemoglobin. Hemoglobin is a protein that is carried by red blood cells or used by organs as an antioxidant and a regulator of iron metabolism. Hemoglobin is made before the cell is made; the alpha chain and the beta chain are made in precisely equal amounts, despite the differing number of genes. The protein chains join in developing red blood cells, and remain together for the life of the red cell.

That would be the macrophage the last stage of the Agranulocyte (without granules) Monocyte. A component of the reticuloendothelial system in humans, phagocytes are defensive cells that "eat" contaminants/invaders, working by envelopment and bioloigcal assault.

It could but not always. Here is some helpfull info: the normal ranges for hemoglobin (Hgb) are 14.0-17.4 g/dL for men and 12.0-16.0 g/dL for women depending on the lab's standards. Hgb is the main component of red blood cells and transports oxygen and carbon dioxide in the body. Decreased Hgb are common findings in patients with anemia or iron deficiencies, liver disease, hypothyroidism, hemorrhage or bleeding both acute or chronic, reactions to chemical, and infections. Also, certain diseases, such as Hodgkin's disease, Leukemia, Lymphoma, and many more, can cause a decrease in the amount of Hgb in the body. An Increase in Hgb can be caused by congestive heart failure or chronic obstructive pulmonary disease. without a full medical histoy and work up it is impossible to know exactly what is causing the decreased Hgb.

Hi there. :-) This result is borderline normal which means you are within the higher end of normal limits and is nothing to worry about. Medical causes for high WBC is usually infection.

Mean platelet volume is the size of the platelets. The higher the MPV the larger the platelet size and the lower the MPV the smaller the platelets. High MPV can cause a person to be at a higher risk for strokes and heart attacks. Low MPV can cause a person to be at risk for bleeding problems (too much bleeding that is slow to stop). There are some natural anti coagulants that help lower MPV blood like flax seed oil and fish oil.

another name for it is clotting

hope it helps

Provide oxygen to the entire body, from the brain to the pinky toe. Blood is circulated via the Pulmonary Artery from the heart to the lungs, and from the lungs (where oxygen is absorbed by the red blood cells) to the rest of the body. After the oxygen has been dispersed, the blood cells begin the cycle anew.

Hemoglobin changes color according to what it is bound to. When it is oxygenated, it is closer to bright red. When it is carrying carbon dioxide, it is darker red or brown. When it is carrying carbon monoxide, it is also quite bright red.

The brain needs so much blood because it needs a constant supply of it to keep up with the neurons metabolic demands. 20 percent of the blood that comes from the heart is pumped directly to the brain.

Hyperglycemia is a medical term for excessive sugar (glucose) in the blood.

5000 to 10,000/mm3

I believe what you're asking is how do red blood cells carry oxygen. They carry oxygen because they contain a compound called hemoglobin which is a protein which is complexed with another compound called heme. Heme can bind an oxygen molecule while that blood cell is passing through the lungs and then releases the oxygen molecule when that blood cell passes through the other parts of the body.

An organ transplant can cost up to 300 000$ in medical fees.

You don't really pay for the organ, it is donated but you pay for the procedure

which is considered a very big procedure.

Depending on the country you live in, the medical fees can be lower.

There are a few major substances that make up the blood in our bodies and there are other substances that are also found in blood. The main substances are plasma, a liquid like substance, the platelets or thrombocytes which help the clotting process of blood. Then the red blood cells (RBC) or erythrocytes, and finally the white blood cells or leukocytes which protects the body from harmful infections.

New fresh blood cells can be formed in under 24hours. Some people have it good and they produce blood in about an hour, not a whole lot but enough to replace the blood you would lose if you got a cut and lost a lot.

No... haemoglobin does not transport carbon dioxide...coz it is our waste which we breathe out....we only take oxygen and after combining with haemoglobin it becomes oxyhaemoglobin.....but if we breathe in pollution for long..... it forms carboxyhaemoglobin.... and it's very harmful to us.

The protein hemoglobin, found in the red blood cells, is what makes blood red.
