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.

Why is there a low hemoglobin level in Kidney Diseased patients?
While the kidney is normally thought of as an excretory organ, it is also an important endocrine organ (ie, one that produces hormones). One of the hormones it produces is called erythropoietin (EPO), which stimulates the production of red blood cells (RBCs). RBCs are basically sacs of hemoglobin that carry oxygen around. The amount of hemoglobin varies according to the number of RBCs in the blood. And the number of RBCs in the blood is controlled by EPO. In kidney disease, EPO production decreases because the kidney is malfunctioning. As a result, RBC count decreases, as does hemoglobin.
Is basophil an Innate or Adaptive Immune system?
No, the first line of the immune system is the intact skin, mucous membranes and their secretions, normal microbiota all are physical barriers.
What supplys blood to the lower body?

What blood alcohol concentration can be used to determine if you are under the influence on a boat?
It depends on local legislation.
Erythrocyte sedimentation rate used to detect and monitor the activity of inflammation as an aid in the diagnosis of the underlying causes of conditions such as especially temporal artheritis or polymyalgia rheumatica. It is considered nonspecific and not diagnostic of any particular disorder.
ESR stands for erythrocyte sedimentation rate. this is a test that indirectly measures the level of inflammation is in the body.
normal readings are

Women over 50 years old---- less than 30 mm/hr
Children Westergren method,
Newborn--------------------------0 to 2 mm/hr

What does it mean when women get black blood?
The meaning behind darker blood varies depending on where the blood is coming from: Darker blood from menstruation could mean that the blood is old because periods are not regular. Dark blood from your veins could mean something like you have too much iron in your blood. Veinous blood as well as fresh menstrual blood should always be bright to deep red, not burgundy or black. If blood is dark you should have it checked out by a doctor.
What is a test for platelet plug formation is?
when the endothelium of blood vessels get ruptured due to any reason(such as trauma) revealing the subendothelial layer, the platelets swing into action quickly to minimize blood loss so as to maintain homeostasis.first of all they release certain biomolecules such as serotonin so as to cause vasoconstriction.simultaneously they on coming in contact with certain proteins of the subendothelial layer release certain biomolecules that attract more and more platelets to the site of injury forming a plug so as to minimize the blood loss.this aggregated form of platlrts is called platelet plug or sometimes called the white clot.this step is the primary one in initiating clotting of blood.
What kind of infection is possible with a high white blood count?
Since white blood cells are tasked with fighting infection, pretty much any infection will cause your body to make them. Unfortunately, some diseases are very apt at hiding from these white cells or they render them ineffective in some way.
Does a blood test test for anemia?
A simple and common blood test used to test for anemia is CBC or the complete blood count. Technically you do not even need a CBC to just test for anemia. A simple Hemoglobin level can detect anemia. But a CBC will give your doctor some more information about the anemia if detected in your blood test. A CBC not only gives you your Hemoglobin level but it also gives you the counts of different types of cells in your blood. It will also give your doctor some more clues about possible causes of the anemia. Simply stated, anemia means a low hemoglobin level in the blood. A hemoglobin level below 8 is critical anemia and normally requires blood transfusion.
Why could you have low hemoglobin levels?
Low hemoglobin is cause from a slow bleed somewhere . Or it could even be a bleed that is heavier .Alot of blod disorders could cause it .I would say slow bleed .
I'd like to confirm that low hgb is caused by anemia or hemorrhage (bleeding).You can get anemia if you lack iron or if you have one or more of the various diseases that cause your body to not make new red blood cells (e.g. aplastic anemia), destroy red blood cells (e.g. sickle cell anemia), or bleed a lot (e.g. hemophilia).
Hemorrhaging (bleeding) due to external or internal injury can cause you to become anemic from loss of red blood cells.
What does a white blood count of 500 in urine mean?
Leukocytes in the urine indicate an infection or some type of damage. This is a nonspecific finding so further testing is necessary for a definitive diagnosis.
Why am i peeing blood and hot?
You could have a UTI. Schedule an appointment with your doctor before it gets bad. I didn't know what it was either, and didn't take care of it. That resulted with me being in the hospital for 5 days because it turned into a kidney infection. In the meantime, take azo cranberry pills and you can go to any vitiman store and get "d-manose" made by solray. You can't take enough of those.

What would happen to your cell if a hypotonic solution is place directly into your blood stream?
Swell and possibly burst depending on how hypotonic the solution was and how much of it was injected. However the human body has evolved many simple and complex ways to deal with these situations and therefore a small amount of hypotonic solution will likely cause no effect to your cells.
In which organ does most digested food enter the blood?
It is absorbed into the blood through the vili in the small intestine.
What might happen to blood flow if you increased the number of blood cells?
Well, first of all, an increase of white blood cells usually means you are sick. This is because the white blood cells are used to protect your body. as far as im concerned, nothing happens to the bloodflow.
How much blood does red crosss take?

What is a low mean platelet volume?
The mean platelet volume measures the size of the platelets.
This figure will be low when there is aplastic anemia, myelosuppression as a result of chemotherapy, in Wiskott-Aldrich syndrome, sarcoma of the bone since blood cells are manufactured in the bone marrow, and a couple of other conditions.
There is a cellular component, this would include red 'cells', white cells, and platelets. There is also a matrix portion, known as serum, this is different from plasma, where plasma is a part of serum.
What test determines if a patient has a blood clot in the femoral vein?
A simple ultrasound can show most "blood clots" (thrombosis, singular... thrombi, plural).
How a leg ultrasound is performed
The patient is asked to remove slacks (pants, trousers) and is given a gown. The underwear can stay on. The patient rests on an exam table which may be slightly elevated to make it more comfortable for the technician. The patient is often flat or the head of the table may be slightly elevated for comfort.
The technician drapes a folded sheet over the groin / privates area, and the gown is pulled up to about the waist. The technician applies a gel--- which has usually been warmed -- to the inside of the leg, high up near the underwear. This means the patient's legs are spread slightly; often the patient must turn that leg outward, bent at the knee in order to give enough room. The technician runs a special tool along the area; the tool also has gel applied on the end which allows for easy movement across the skin. The technician turns or tips the tool in order to best see the vein or artery. The test includes from the top of the femoral artery and vein, down the inside of the thigh, to the back of the knee. They may also view the area right on the groin where the femoral pulse can be felt at the very top of the leg (thus, the underwear elastic is moved to the side).
During the test, the technician may turn the audio off or on periodically. When "on", you will hear how the sound of bloodflow through your artery or vein.
After the test
After the test, the technician (or patient) wipes off the remaining gel with towels. After cleaning up, the patient re-dresses and, if out-patient, often returns home. IF the technician thinks the patient needs immediate care, the patient will receive that info before leaving.
Other
Other tests may be performed as well, especially if an artery is blocked.
Also, routine blood tests are often drawn to check platelets and other blood components. Note that platelets can become "thick" and sticky if a person is chronically dehydrated.
Treatment
If diagnosed with a thrombosis, medication is immediately started to break up the clot. Heparin (IV) is given if hospitalized. All oral meds must be taken as directed, usually with weekly blood testing. The patient may need to change the foods they eat if on clot-busting meds; some foods interfere.
Sometimes, surgery is needed to remove the clot or to insert a "stent", a small screen-like device that prevents clots from traveling up the body to the heart, lungs, or brain as an embolism.
Prevention
Besides lowering triglycerides through dietary measures, patients also need to drink plenty of water / fluids. If you drink alcohol, remember that alcohol causes dehydration, so drink a glass of water at least 1x an hour. All people who sit for long periods risk getting clots in the legs-- therefore, stand every 2 hours at least. Walk for a few minutes if you can, or flex onto your toes while standing. While sitting, flex each foot, toes toward leg and relax; repeat on each side several times during every hour, especially if taking a long car or airplane trip. Avoid falling asleep in a chair with your feet down. Report any pain or redness in the calf immediately so the Dr can evaluate for thrombosis.
What helps in the formation of a blood clot?
the part of the blood that closes a wound is called the platelets.
