Blood

About every month a woman gets rid of an egg from her womb (period) and the 'blood' that is expelled during a period is the old "blood rich" lining of ones womb.

At the beginning of a period, the blood looks redder because it is freshly being sloughed off (sliding off, sliding away) from the walls of the uterus. As the period progresses, the blood becomes darker, indicating it is old blood. (Meaning: If a doctor saw bright red blood, it indicates a new "bleed"-- anywhere in the body. Old blood is dark red to light or dark brown, meaning old blood and therefore of less concern unless it is in vomit.)

No, the mothers and fetus blood supplies do not mix because some babies are born with different blood types to the mothers and mixing the two different blood types could be deadly to the baby.

Individuals working in healthcare may be placed at-risk for HIV infection during occupational exposure. It is important to report incidents immediately when they occur and seek proper medical care.

Coming in contact with another person's blood is a risk for a variety of bloodborne illnesses. There are preventative measures that can be taken that help reduce a person's risk of infection in some cases.

Report the incident ASAP and discuss your options with your supervisor.

It is just new blood, you get the dark blood often? Which is the older blood. But yes, it is just new fresh blood, you know when you get a cut on you knee is somewhere? You then get a scab and it's just as it se scab has come of and then you get the fresh blood. I hope this helped.

white blood cells

Platelets are net fibers that cover wounds and stop the external bleeding and helping it heal

it makes it easier for the lungs to get rid of carbon dioxide.and makes sure only blood with oxygen not carbon dioxide travels to the rest of thebody

It actually is low for a platelet count just came from the doctor two days ago and mine was at 23 the put me on on steriods for four days to bring it up will update when i find out if it brought them up

That means you have an increase of white blood cells in your urine, it could mean you have an infection in your gential area, seek professional help.

Well they measure hemgb. In many diff forms.

Such as:

Hglb. Serum which range is 1-4 mg

(iron-containing oxygen transporting meralloprotein in RBCs)

Hglb. AC1 >7%

(form of Hmglb. Measures primarily to identify avg. plasma glucose concentration)

And norm "known" hglb (the one u were most prob referring to) for

Male- 13.2-17.5

Female-11.5-16

The general term for pathologic changes to circulating blood cells is blood dyscrasia. Some of the categories would be morphologic changes to the cells (such as sickle cell animal, microcytosis, etc.), increased numbers of immature blood cells (such as seen in regenerative anemai), gross nuclear changes (usually indicative of neoplastic changes) and inappropriate cell numbers (either too high or too low).

Its in its purest form when its unexposed to oxygen. The CO2 in the air mixing with the blood cause it to turn red, whereas blood is actually purple when it is unexposed to oxygen.

120 is a very low number for sodium, and may result in seizure activity. The normal range for sodium is 135 to 145 mEq/L (millequivelents per liter.)

Just to add to this, my sodium is 122 and my doctor said that this is very near critical. If you have a blood sodium level at 120 your doctor should be taking steps to correct it and find the cause.

There are four main components to blood; plasma, red blood cells, white blood cells and platelets. The liquid that suspends the blood cells and platelets is the plasma.

Why is it important to keep the blood healthy?

Platelets are cell fragments which are an important part of blood clotting. Similarly to red blood cells, they don't have a nucleus, but they are a lot smaller than red blood cells. When there are too few platelets, wounds don't close as well and you bleed more. Conversely, when there are too many, your blood clots too easily and blood clots might form without there being a wound - leading to thrombosis. However, the range of platelet counts that are healthy is very large, unlike for other blood cells. If you're on the lower end, somebody with five times as many platelets as you might still be perfectly healthy.

How they work: When a blood vessel is injured, blood comes into contact with the protein mesh underneath the vessel wall. This mesh contains collagen. Blood contains platelets, but also a protein called Von Willebrand Factor (VWF), which sticks to collagen. Once it is stuck down, VWF itself becomes sticky for platelets which are also in the blood. This way, VWF becomes like glue stripts for platelets to stick onto an injury. This causes platelets to activate and stick to each other, forming a plug over the injury. There are more details to what platelets do, but this is their main function.

Plasma is the light yellow liquid in which red and white blood cells and platelets are suspened. it also dissolves the nutrients that travel in blood.

Hemoglobin is the oxygen carrier.

Eating carbs increases your blood sugar level. When the body detects a rise in blood sugar level, the pancreas produces insulin, which is a hormone thaat converts sugar (glucose) into an insoluble, storage form (glygogen). Alternatively, the sugar is converted to, and stored as, fats. Glygogen and fats are then used to raise the blood sugar level at times when it falls below normal.

The erythrocyte (RBC), leukocyte (WBC) and the platelets are all formed in bone marrow. While the erythrocyte and leukocyte are produced from the hematopoietic stem cells, the platelets are are derived from fragmentation of precursor megakaryocytes.

arterial blood

Yes, it induces a heart attack, that's why doctors, nurses and such, flick the needle to remove the air bubble.

----------- Answer -----------

Putting air in your vein will form bubbles like putting air in water. However, bubbles in your vein have no where to go but toward your heart/lungs. There, they will circulate to other organs via the arteries. This condition is called air embolism. These bubbles can cause obstructions at some of the small arteries causing heart attacks, strokes, or other ischemic injuries to other organs.
