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.

How does hemoglobin carry 02 in the blood?

It attaches itself to red blood cells(erythrocytes). Hemoglobin is what transports oxygen from the lungs to the rest of the body.

What is a fasting blood test?

Fasting blood sugar is a medical test that measures the level of glucose (sugar) in your blood after an overnight fast. This test is usually performed in the morning before you have eaten anything and is used to diagnose and monitor diabetes, a condition in which the body is unable to properly regulate blood sugar levels.

A normal fasting blood sugar level is typically between 70 and 100 mg/dL (milligrams per deciliter) or 3.9 and 5.5 mmol/L (millimoles per liter). A level between 100 and 125 mg/dL or 5.6 and 6.9 mmol/L is considered prediabetes, while a level of 126 mg/dL or 7.0 mmol/L or higher indicates diabetes.

Fasting blood sugar is usually measured through a simple blood test, which involves drawing a sample of blood from a vein in your arm. The test is quick and relatively painless, and it is an important tool for managing and preventing diabetes-related complications.

If you prefer to purchase the book from a different retailer, simply search for "Smart Blood Sugar" on their website and follow their purchasing process.

What is a normal platlet count?

A normal platelet count is 250K to 400K per mm3 of blood.

What is straw colored and carries solid parts of the blood?

The straw coloured liquid that makes up a lot of blood is called Plasma.

Plasma is not blood type specific, so it can be given immediately in event of blood loss when the casualties blood group is not known.

The body can regenerate a pint of plasma in about a day, so it is possible to donate this more often than a donation of normal blood, as the red cells take longer to regenerate.

What causes enlarged white blood cells?

I've recently had blood tests and been told white white blood cell count was 106 which it seems is high. I had shoulder surgeri in november and i am still suffering a lot of pai. Swollen legs and extreme tiredness. Any connection in symptoms?

Which part of the blood carries water around the body?

The part of the blood cell that carries water around the body are the plasma cells

What is HCT use for in blood work?

The HCT blood panel tests for an individual's hematocrit. What the hematocrit refers to is the percentage of someone's blood, by volume, that is made up of red blood cells.

How is platelets transported?

Similarly to Red blood cells, Platelets are collected from bone marrow, transported via diffusion and then destroyed in the spleen 120 days later.

What tissue has no direct blood supply?

Tough to answer when the question is phrased so poorly, but a lot of tendons and ligaments have poor blood flow since they are avascular.

So, tendons and ligaments.

Does the blood alcohol concentration rise more slowly in a experienced drinker?

No. However, the effects tend to occur more slowly as a result of tolerance to alcohol.

How is phagocytes similar to lymphocytes?

A phagocyte is a cell that "eats" something, like for example a pathogen/ antigen. Like a pacman kind of cell (sorry for being a child of my generation ;-). Now, being a lymphocyte says nothing more than that the cell is a part of the humoral immune system. And since a B-lymphocyte eats an antigen in its process of immunological defence, it is also a phagocyte. Hence, phagocyte is a classification that decribes the MO of the cell.

There are also other phagocytes like for example macrophages (they eat a lot), monocytes or dendritic cells.

What is cold plasma pen?

A cold plasma pen is a medical device that generates cold atmospheric plasma for various therapeutic applications, particularly in dermatology and aesthetics. It works by producing ionized gas that can promote wound healing, reduce inflammation, and stimulate collagen production. Cold plasma treatment is non-invasive and typically used for skin rejuvenation, acne treatment, and other skin conditions. It is considered safe with minimal side effects and often requires little to no downtime for patients.

Is blood red because iron?

Blood is red because oxygen makes contact with it.

Why is artificial blood used instead of real blood?

What would happen if the blood is not filtered?

If urine wasn't filtered in the kidney, the particles in the urine would cause your genitals to explode.

Is antibodies the same as white blood cells?

No, not even close.

White blood cells are cells that circulate in your blood and lymph.

B-cells are a type of white blood cell that start producing antibodies when they are shown what the antibody is needed for. For example, if your body has a bacterial infection, other cells 'pick up' debris from these bacterial cells, and 'show' these debris pieces to the B-cells. These B-cells then transform into 'plasma cells', which start producing antibodies specific for that particular bacteria.

Antibodies basically 'stick' to any of that same bacteria that they find around your body, acting as a flag, so that your other immune cells can find it and attack it.

What is the function of a thrombocyte?

Platelets (thrombocytes) are the smallest type of blood cell. They are important in blood clotting. When bleeding occurs, the platelets swell, clump together, and form a sticky plug that helps stop the bleeding. If there are too few platelets, uncontrolled bleeding may be a problem. If there are too many platelets, there is a chance of a blood clot forming in a blood vessel. Also, platelets may be involved in hardening of the arteries (atherosclerosis).

What does Oxygen bind to the of deoxyhemoglobin?

Oxygen binds to the Fe(II). This causes a shift of the Fe(II) to be in plane with the porphyrin ring and it pulls the His in, which all increase the oxygen affinity.

Why do elderly people have a decrease in hematocrit?

including chronic and recent acute blood loss, some cancers, kidney and liver diseases, malnutrition, vitamin B12 and folic acid deficiencies, iron deficiency, pregnancy, systemic lupus erythematosus

White blood cells that ingest bacteria to prevent infe ction?

they're called phagocytes (literally, phago = eat, cytes = cells)

When someone can't stop bleeding?

There are various causes of slow blood clotting. A rare, but fairly well known condition, is Hemophilia. A person with Hemophilia is called a Hemophiliac. Only about 400 babies with the condition are born each year in the US. Most of the disorders in the body's ability to form blood clots to stop bleeding involve an hereditary absence of a clotting factor in the blood.

Clotting factors are proteins carried in the blood that help form blood clots. They form the clots working with platelets, cells that were formed in the bone marrow, that are also in the blood. The platelets stick together to stop up an injured blood vessel with a clot that is held together with the help of the clotting factor proteins. Hemophiliacs can be helped by injections or intravenous infusions to replace the missing clotting factors.
