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.

Where do B lymphocytes develop immunocompetence?
Both type of lymphocytes are made in the bone marrow and only the B - Lymphocytes mature in the bone marrow, whereas the T Lymphocytes travel to the thymus gland where they mature.
What does a high white blood cell count in an alcoholic signify?
No only that, But they can destroy brain cells and seriously make you a little slow or mentally retarded. Excessive alcohol can damage the immune system because the alcohol will prevent nutrients from feeding your immune system. The alcohol is absorbed into your bloodstream through your stomach. Once in the bloodstream, alcohol will reduce the white blood cell count in the body. The lower the number of white blood cells, the more difficult it is to fight off disease. Alcohol also combines with red blood cells for the process of "blood mudding." In this process, red blood cells clump together and cause smaller blood vessels to plug up. This reduces the flow of oxygen to many vital organs. With less than an optimal amount of oxygen, your organs and your immune system will not operate at peak efficiency.
Amount of AlcoholTaking one or two drinks a night is not likely to harm your immune system. Three or more drinks a night is a significantly different story. If an individual drinks enough alcohol to get impaired or drunk, it is also enough to cause weaknesses in the immune system. When you drink enough to get drunk, you are also producing an nutrition deficiency. This will weaken your immune system. Additionally, the consumption of alcohol impairs the function of B-lymphocytes, which produce antibodies in the blood. These antibodies ward off viruses and other diseases that may attack the body.Which of the formed elements contains hemoglobin and transports respiratory gases?
I do believe that the answer is erythrocytes. Erythrocytes are the formed element in blood that transport oxygen and carbon dioxide.
What is the term for blue skin from lack of oxygen in the blood?
It could be anemia, or it could be carbon monoxide poisoning.
Hypoxia
Actually, hypoxia can be characterized as cellular oxygen deficiency and may occur if too little oxygen enters the blood. The correct answer would be anemia.
Anemia
simply anemia
Anemias
anemia
Anemia is a blood condition where their is either a reduced amount of hemogloblin molecules, or the inability to efficiently bind oxygen molecules to hemoglobin. Hemoglobin molecules are located within red blood cells. As red blood cells pass through the lungs, the hemoglobin unloads carbon dioxide and exchanges it for oxygen. Up to four oxygen molecules can bind to each hemoglobin molecule. Hemoglobin then transports the newly loaded oxygen molecules throughout the systemic portion of the cardiovascular system, where they are once again exchanged for carbon dioxide at the tissues (and the oxygen is unloaded into the tissues). Individuals with anemia cannot transport adequate amounts of oxygen to tissues because their is either not enough oxygen molecules bound to hemoglobin, or the hemoglobin are not properly functioning as they should. Amemia is the most common type of blood disorder. Hope this helps!

How many blood cells die in the human body each second?
2 million are produced in the red bone marrow every second.
2 million are thus also killed in the spleen in order to keep the balance.
The cells live for about 120 days
so you have about 2E13 red blood cells in your body at one time.
Pigment produced by the destruction of hemoglobin in the liver is called?
When the erythrocytes are destroyed, haemoglobin breaks down, the heme part of it goes through a series of transformation:
Heme → biliverdin (green pigment)
biliverdin → bilirubin (orange-yellow pigment)
Bilirubin + blood albumin → bound bilirubin (in peripheral blood)
Bound bilirubin + glucuronic acid → conjugated bilirubin. (in liver)
Conjugated bilirubin + intestinal bacteria → several pigments, including
- stercobolin (orange-brown pigment, excreted in feces) and
- urobilinogen (reabsorbed into bile/blood, finally excreted in urine)
Why does our body remove water and salts from the blood?
When we consume sugar, our bodies manufacture insulin in order to take the sugar out of our blood. If we eat too much sugar, it is turned into fat.
What are normal hemoglobin levels or amounts of iron for neonates?
Normal levels of hemoglobin for neonates are 17 - 22 g/dl.
What happens if you have high platelet count?
Having a high platelet count may result to thrombosis, meaning, blood clot formation in the blood vessels. This is quite dangerous since there may be a chance that this blood clot (called thrombus) maybe dislodged (now called, embolus). The embolus (emboli-plural) now circulates in your system and may get stuck in an artery causing obstruction in blood flow. This is dangerous if the emboli obstructs a major artery, depending on the organs involve, it may lead to myocardial infarction (heart attack)congestive heart failure, renal failure, cerebrovascular accident (stroke), etc.
Do Phagocytic cells ingest pathogens and cellular debris?
The phagocyte that digests cellular debris and pathogens in the human body are called macrophages, or macrophagocytes.
Does the liver filter blood as well as kidneys?
Yes, both organs filter blood. Although, they filter blood in different ways, but in many cases work together. The liver picks out chemicals and such that need to be chemically changed for many different reasons. For instance, it can pull fat molecules out of blood for packaging and transport to fat stores, or it can pull toxins out and turn them into non-toxic forms. Basically, the liver does most of the biochemistry in your body, and since it uses the blood stream as a means of transporting things with the rest of the body, must filter it in order to grab all of the things it needs to work with.
The kidneys filter blood in a drastically different way. They let small stuff fall out of the blood randomly into them. Then, they decide whether the randomly fallen-out molecule is useful or not. If it is, they pull it back into the blood. If it isn't, they let it continue down the path toward urine for removal from the body. For instance, the less-toxic molecule that used to be a toxin would be dropped into the kidneys and let to fall into the urine collection for excretion, while sugar molecules would be picked out and shoved back into the blood so that they could feed cells.
How much water is in the human blood?
Blood is 55% Plasma, and plasma is about 90-92% water, which makes blood about 50% water. So in one liter of blood there is about half a liter of water.

What is the total volume of the blood in your body?
You have about five liters of blood in your body. You have two liters of the cells and three liters of the plasma in your blood.
What is the medical term meaning systolic?
Systolic Pressure (the other is Diastolic) is the squeezing of the ventricles as they push blood out of the heart and along the arteries to either the body or the lungs.
Diastolic Pressure is when the heart is at its most relaxed after the Systolic squeezing.
ie a Blood Pressure reading of 120/80mm Hg (which is the ideal) is 120mm HG Systolic Pressure - when there is the most force pushing the blood - over 80mm HG - when there is the least force behind the blood flow.
systolic reading denotes the force of contraction of heart and diastolic reading represents relaxation of heart
Is your iron low if your period blood is an orange color?
It's very possible. The only way to find out what's going on is talking to an OB/GYN doctor, an RN, or just a doctor. Good luck
What colors would you use to represent blood?
Blood is usually red, though old English Folklore says that Royalty's blood is blue. This is not true. Human blood is a deep, scarlett red.
The blood appear red due to TIR(total internal reflection) but the individual red blood cell appear deep yellow However normally when dead your blood hardens and bursts your veins blood then appears brown
Are leukocytes red blood cells?
Leukocytes are among the formed elements of blood. They fight infection and identify and neutralize other "foreign" invaders. The formed elements of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Is a white blood count of 69 too high?
I don't know what amount of blood you are measuring from, but the average amount of white blood cells per cubic millimeter of blood is between 2,000 and 7,500.
How soon can a pregnancy test show you are pregnant?
First Response Early Result can tell on the first day of your missed period. And can sometimes tell before your missed period. It is best to get the two strip kit and test and a week later test again to be sure of pregnancy or no pregnancy.
Answersome tests can tell as soon as three dayswhat test tells as soon as 3 days??just curious
well on the day of your missed period is advised I know its a long wait!(im 20weeks) but I waited til my second day and got an immediate a little faint positive and at that time i was a little over 5 weeks. best to wait until missed period but no sooner then 3 days for accurate answers...best advice i can give
What is the renal threshold for glucose?
When the blood glucose level exceeds about 160 - 180 mg/dl (8.9 - 10 mmol/l), the proximal tubule becomes overwhelmed and begins to excrete glucose in the urine. This point is called the renal threshold of glucose (RTG) hope that this answer might help you and it is taken from wikipedia.
