Blood

Blood is a bodily fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. In many species, it also carries hormones and disease-fighting substances. In this category, you will find questions about the blood in your body, including blood types, blood diseases, and the function of blood.

What happens if you lose 2 pints of blood?

One would be dead or close to it. The person would be in severe shock and could be dying. This is an emergency situation. Losing two pints of blood is dangerous, much less 2 Liters. Call 911 if this is an emergency or see your healthcare professional for additional information pertaining to this question.

Why does plasma color is pale yellow?

it could be yellow but it depends on what plasma you mean

What happens when normal Red blood Cells are placed in hypotonic solution?

Hypotonic means that the concentration gradient is lower than what ever your comparing it to (in this case a red blood cell) since the net movement of solute goes from high to low concentration gradient solutes will move out of the red blood cell causing water to go into the cell. This will cause the cell to swell up and eventually Lyse.

What is a Neutrophile?

"Neutrophila" is a misspelling of neutrophilia.

Red blood passes through the smallest what in single file?

The tiniest tubes that carry blood are the capillaries. These connect arteries and veins.

What is a white blood cell with a solid nucleus and clear cytoplasm?

Why do you expect them not to have nucleus?! Every cell has a nucleus. Red Blood Cells don't becuz they're specified to have more Hb to carry O2. White Blood Cells in common with many other cells have nucleus to control their activities, regulate their secretory, in one word, to arrange their life!

White Blood Cells have nucleus due to below reasons:

-they must have antibodies to detect antgenes and prevent them from teasing us! [these antibodies are protein based and they're built from a genetic code which is in the nucleus!]

-they must have nucleus to regulate their growth, cell division, and differention in order to build plasmocytes and memory cells.

-They must have, to secrete antibodies to attack antigenes.[must have genes to be transcripted to mRNA and at last be translated on Ribosomes which are located on RERs.]

Can o blood type contract the aids virus?

Yes. No blood type is immune from the HIV virus.

Why do red blood cells take oxygen to the working muscles?

Red Blood cells take oxygen to the working muscles as it is required for respiration.

Is plasma hot?

Human blood temperature is 37 degrees C or 98.6 degrees F, the same goes for the plasma found in blood.

The plasma found in your blood is not the same as the 4th state of matter of the same name. In physics and chemistry, plasma is a state of matter similar to gas of high temperatures in which a certain portion of the particles are ionized.

Blood plasma is the straw-colored/pale-yellow liquid component of blood that normally holds the blood cells in whole blood in suspension.

Which substances are removed from blood plasma by the kidneys?

The waste products of metabolism are removed from your blood. Urea and creatinine is too toxic for your brain. They are removed from your blood by your kidneys. The extra water and sodium as well as potassium and other salts are removed by your kidneys. The drug metabolites are also removed by your kidneys. The urine becomes acidic or alkaline to preserve the pH of your body.

What causes a low lymph blood count?

There are several things that can cause low lymphocytes in your blood. Lymphocytes are the white cells in your blood which are your bodies defense system against viral problems and infections.

Low white cell count can be caused by many things as I've mentioned above & it really depends on how low your lymphocytes are. But basically low lymphocytes are caused by immunity problems (weak immune systems) or infections. Low lymphocytes can also sometimes indicate a blood disorder. See a hematologist for more intense blood testing.

What are the conflicts in under the blood red sun?

Tomi's father and grandfather are arrested, and Tomi has to learn how a Japanese kid will live in Hawaii during WWII.

Why are platelets important in physical activitysports?

platelets form blood clotting, so when a performer has an injury, such as a cut or graze, platelets in the blood form fibres and (blood clots, preventing blood flow) and a scab is formed over the wound to prevent infection.

What is the stimulus for red cell production?

The body's chemical signal to make more red blood cells is erythropoietin. Triggers for releasing this chemical include low oxygen levels in the blood stream, anemia (lack of red blood cells) and increased oxygen demand (such as by starting a vigorous cardio exercise program).

How do you rebuild white blood cells?

If you have a high wbc count then most likely you have some sort of infection and you need to go see your doctor. He/she may prescribe an antibiotic, depending on what kind of infection you have.

In any given 3mm of blood what is the approximate ratio of the number of red blood cells erythrocytes to white blood cells leukocytes?

Blood cells are predominantly red cells. They outnumber the white cells by a factor of 1000:1 to 2000:1 in normal humans.

The composition of blood is 55% plasma and 45% formed elements. The formed elements are mostly red blood cells, which make up 44% of total blood volume.

The remaining 1% consists of white blood cells and platelets.

Appx. 700:1

Blood consists of formed elements (red blood cells, white blood cells and platelets) and plasma. Red blood cells (erythrocytes) account for 99.9% of cells. Plasma 55%, and Cells 45%.

What low blood count dangerous?

What can you eat to raise your red blood platelets if anything, and is it dangerous. I had a blood test that showed my Red blood platelets are low, and the doctor said come back in 60 days, is it dangerous to wait that long? thanks...

What is a normal rbc?

Red blood cells, whose size, shape and hemoglobin levels are within the normal standards.

Diameter: 6-8 micrometers

Shape: Biconcave (Dough-nut shaped)

Hgb level:

* Males: 13-18 g/dL * Females: 12-16 g/dL

Mostly, any deviations from those reference ranges can be defined as a form of anemia, e.g. microcytic hypochromic anemia; which means anemia characterized by a small sized RBC with low levels of Hb

The above levels are for Hemoglobin only, so to answer the question more completely, the levels for RBC's are: · Males: 4.71mm³ - 5.14mm³ · Females: 4.2mm³ - 4.8mm³

What are different kind of white blood cells?

Leukocytes are divided into granulocytes and agranulocytes:

1. Granulocytes (have granules in their cytoplasm).

a.Neutrophils are the most common. Eat disease organisms (phagocytes).

b.Eosinophils kill parasites

c.Basophils release heparin and histamine, may move from blood to go to site of infection and are called mast cells

2.Agranulocytes (without granules)

a.Monocytes largest white cell moving to tissues as a macrophage.

b.Lymphocytes longest lasting (up to years) involved in antibody actions.

The red blood cell will become turgid because water will move from the glucose solution to the red blood cell.

How do the blood and blood vessels work together?

Blood is composed of a fluid portion and a solid portion made of blood cells, also known as formed elements. About 45% blood is made up of blood cells. These are of three types: erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets). Erythrocytes help in the transportation of oxygen to the cells of the body with the help of hemoglobin (respiratory pigment) also due to which they appear red in color. These are biconcave in shape. They live for just four months and are without a nucleus, so they cannot reproduce. Leukocytes are white in color and larger in size and they defend the body against pathogens. Thrombocytes are fragmented cells.Their role is in blood clotting.

Blood vessels are the pathways for the flow of blood. These are of three types: arteries, veins, and capillaries. These three differ from each other due to their structure of walls which is related with their function.
