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.

Is the function of leukocytes blood coagulation?

False- the leukocytes participate in protecting the body from infection; Coagulation is a complex process by which blood forms clots. ex: if you cut or stick yourself and blood begin to flow, immediately the blood forms a kind of thickness (like a film coating on the outside) and the blood begins to slow down, this forms a clot. The platelets immediately forms a plug as you will at the site.

The proteins in the blood is called the coagulation factor or the clotting factors to stop the blood from flowing more as the plug gets strong as it stops the blood.

So in otherwords, no it is not the function of the leukocytes it protects inside from foreign objects

Hope I explained it in a way you catch what its meaning.

Why does blood clot outside the body and not inside?

Blood in the body is constantly moving, and is in liquid form. Any cut you get that bleeds - signals the body to produce platelets - which clump (or clot) together to form a seal over the cut. As the cut heals, the scab falls off - leaving new skin underneath.

What causes high level of basophils in blood?

High levels of Basophils generally correspond to an active allergic response. Normal levels generally vary from zero to 2% of the existing white blood cells. Their elevation does more to establish that a higher WBC is due to a natural, proper physiological response rather than a disease process. I wouldn't worry (which is, I assume what your physician also told you) but if you would like to do something about it, you can start by examining what you are consuming or exposing yourself to that may be causing the allergic response (which is probably also not anything to worry too greatly about.)

Why does blood come out of your mouth if you get shot?

You could have cut your mouth. Additionally, you could have sustained serious head or other internal injuries if the accident (incident) was severe enough. Bleeding from the mough is something that needs to be promptly assessed. The souce of the blood might be the sinus cavities in the head, or it might be coming up from the lungs or stomach. And this is different from bleeding from a cut or tear in the tissues of the mouth. If the cause is a severe head injury or other internal injuries, immediate emergency care is the order of the day. You can be bleeding into your thoracic or abdominal cavity and not know it. And this can be fatal in short order. It's a 911 situation. Call for emergency medical care to come to the scene.

How low does your Hb need to be before they do a blood transfusion?

normal hemoglobin level is between 12-18 g/dL. elderly patient's may be slightly less.

Which organ passes oxygen to blood?

The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.

Why red blood cells do not contain blood vessels?

Red blood cells are too small to contain blood vessels. They are cells and they travel in blood vessels.

What is the role of a platelet?

Platelets help your blood to clot.
The blood is composed of 4 main things: white blood cells, red blood cells, blood platelets and the straw coloured fluid that they float in, called plasma.

The function of blood platelets is to form a clot (scab) over the area that was cut, so that the blood doesn't keep oozing out of the cut.

Blood platelets form clots.

What is the main ingredient in human blood?

What does it mean if you have blood in your poop?

If you have blood in your feces you may have hemorrhoids. The above poster is correct, but you could also have what they fissures which are small cuts in the rectal area causing bleeding. If this continues please see your doctor and they will take a stool sample from you (you can do it at home) and give you a small package and you will put a sample of your stool on that and then you more than likely can take it to a lab closest to you (your doctor will give you instructions.) The best way to attain a stool sample is to lift the toilet seat, put a piece of Saran Wrap across the toilet hole (leaving a small pocket to collect the feces) and then put the toilet seat lid on top of the Saran wrap. Once finished just take the stick that comes with the kit and scoop a little out and brush it across the ribbed card that is given. Fold it up, put the date, your name and the time you took the stool sample and follow the doctors instructions.

How many binding sites does hemoglobin have?

Hemoglobin has four binding sites for oxygen molecules. Each hemoglobin molecule consists of four subunits, and each subunit can bind one oxygen molecule, allowing hemoglobin to carry up to four oxygen molecules in total. This tetrameric structure is crucial for its function in transporting oxygen from the lungs to tissues throughout the body.

What does Occupational Exposure to blood borne pathogen?

Occupational exposure to blood-borne pathogens means work-related accidents like needlesticks or splashes to mucous membranes of someone else's blood or bodily fluid that might contain pathogens like HIV or hepatatis virus. Occupational exposures are possible job hazards for health care workers, cleaning staff, and emergency responders.

What happens to the body when hemoglobin levels are below 5?

Normal blood results vary from lab to lab depending on what equipment they use. At the one I use, normal Hbg for women is 11.7-15.5, MCH is 27-33, and MCHC is 32-36. Your results are not that far off normal. There is no way to tell from a simple blood count if you have internal bleeding, but with results this good, it is highly unlikely. Anemia is the most common cause of low hemoglobin. MHC is mean corpuscular hemoglobin. It is a measure of the hemoglobin in red blood cells. Smaller numbers would indicate a microcytic anemia. MCHC is mean corpuscular hemoglobin concentration. Dilution (lower numbers) usually means a condition like iron deficiency anemia. However, these numbers all by themselves indicate nothing. They are taken along with all the rest of the blood count, any other tests that were done, and the clinical picture. The results shed no light on why you have pain under your rib cage.
