If you assume the density of blood is 1.060 gmL what is the mass of 6.56 pints of blood in grams?
1 pint = 0.568 l 6.56 pints = x liters X liters * 1060 g/ liter = 3949.6448 g = 3,9496448 kg ~ 4 kg For x u need to make calculation but i just did it on calculator and than multiplied so i do not have intermediate outcome
Lymphocytes can live for weeks to years, depending on the specific type. B cells can live for a few days to several weeks, while memory T cells can persist for a lifetime. Factors such as the type of lymphocyte, presence of infections, and overall health can influence their lifespan.
What are the principle of hemolysis?
Hemolysis comes from the Greek word Òhemo-Ó which means ÒbloodÓ and ÒlysisÓ meaning ÒloosingÓ, Òsetting freeÓ or ÒreleasingÓ of the red blood cells. The basic principle of hemolysis is called blood agar, a rich component that contains 5-10 percent blood.
What is another name for a white blood cell?
Another name for a white blood cell would be a leukocyte.

Function of a red blood cell is?
The main function of a red blood cell is to transport oxygen from the lungs to the body's tissues and organs, and to carry carbon dioxide back to the lungs to be exhaled. This process is vital for sustaining life and providing cells with the oxygen they need to produce energy.
How long does it take for a red blood cell to reproduce?
Red blood cells do not reproduce, as they do not contain a nucleus or organelles necessary for cell division. They are produced in the bone marrow and have a lifespan of about 120 days before being broken down and recycled by the body's immune system.
What are the stages of mitosis?
The five basic stages of mitosis are: interphase, prophase, metaphase, anaphase and telophase.
In prophase, the genetic material in the nucleus condenses and the duplicated chromosomes become visible. The nucleolus disappears and the nuclear envelope begins to break down, spindle fibers also start extending from both poles of the cell. In metaphase, the duplicated chromosomes become aligned in the center of the cell, spindle fibers attach themselves to the centromere of the chromosomes. In anaphase, the stage of mitosis in which the duplicated sets of chromosomes separate and two identical groups move to opposite poles of the cell. in telophase, a nuclear membrane re-forms around each new group of chromosomes.
The difference in electrophoretic pattern between normal hemoglobin A and hemoglobin S is due to a single amino acid substitution. In hemoglobin S, a glutamic acid is replaced by a valine at position 6 of the beta-globin chain. This change causes hemoglobin S to have a different charge, leading to its characteristic migration pattern on electrophoresis.
How serious is a hemoglobin count of 16.5 in a woman?
A hemoglobin count of 16.5 g/dL in a woman is considered high, but not necessarily a cause for concern on its own. It could be due to factors such as dehydration, smoking, or living at high altitudes. However, if it is a persistent elevation, it may warrant further investigation to rule out conditions like polycythemia vera or lung disease.
What might happen if too much water moved into a cell?
If too much water moves into a cell, it could cause the cell to swell and possibly burst. This is known as lysis and can ultimately lead to cell damage or death.
Why are platelets essential to survival?
Platelets are essential for blood clotting, which helps prevent excessive bleeding from injuries. Without platelets, individuals would be at risk of hemorrhage and unable to stop bleeding, which could potentially be life-threatening. Platelets also play a role in repairing damaged blood vessels and contributing to the immune response.
Erythropoitein which stimulates red blood cell production is produced by the?
Kidneys!
it is not known that exactly where the erythrropoitein form in kidney.
it is most likely that it is secreted by renal tubular epithelial cells
Why does hemoglobin decrease in diarrhea?
There are a number of reasons why hemoglobin may decrease in diarrhea. Some of these causes could be from a vitamin B12 deficiency, folate deficiency, colorectal cancer, alcoholism or lymphoma.
What important property is in plasma?
An important property of plasma is that it is an ionized gas. It is the fourth state of matter and different from the other three because its free electrons are very mobile. This makes plasma a very good conductor of both heat an electricity.
Platelets are small, disc-shaped cell fragments with no nuclei. They are the smallest type of blood cell and play a key role in blood clotting by forming clots to stop bleeding. Platelets are typically 2-4 micrometers in diameter.
Why is the temperature of blood higher than the body temperature?
The temperature of blood is the same as the body temperature, which is approximately 98.6°F (37°C). Blood helps regulate body temperature by carrying heat away from internal organs to the skin, where it can be released. If blood temperature were higher than body temperature, it could lead to overheating and damage to the body.
How do white blood cells defend the body?
White blood cells defend the body by recognizing and attacking foreign invaders such as bacteria, viruses, and other pathogens. They can engulf and destroy these invaders or produce antibodies to help neutralize them. White blood cells also play a role in regulating the immune response and promoting healing.
What carries other wastes from each body cell?
The circulatory system carries waste products (such as carbon dioxide) away from body cells to be eliminated by the lungs or kidneys.
What is the advantage of automatic blood cell counter?
The primary advantages would be speed (and thus throughput) and statistical accuracy.
Automated Cell counters actually count vastly more physical cells than are normally possible with a manual cell count, even though they analyze a smaller sample by volume.
The only potential problem of note with automatic cell counters is that they can be confused by certain types of abnormal cell, which can necessitate a further manual examination if the sample. More modern cell counters will produce error cdes of various sorts wen they encounter the unusual, though this was not always the case in the past.
What happens to red blood cells that are agglutinated?
red blood celld that are agglutinated are destroyed by the immune system. If they remain in your system as damaged it is unhealthy. This is because it can cause major problems such as organ failure.
What is the absolute number of white blood cells in the differential?
The absolute number of white blood cells in a differential count refers to the actual count of each type of white blood cell present in a microliter of blood. This count helps determine if there are any abnormalities in the distribution of white blood cells.
How does passive transport affect red blood cells?
Passive transport allows substances like oxygen and carbon dioxide to move freely across the cell membrane of red blood cells without the need for energy. This process helps maintain the proper balance of these gases, allowing red blood cells to efficiently transport oxygen to tissues and remove carbon dioxide from the body.
Why is hemoglobin said to combine reversibly with oxygen?
As I understand it, and very simplistically, I think it means that the bonding is easily reversible. In other words, the O2 is readily bound to haemoglobin but is also readily released depending on the partial saturation levels of Oxygen (PO2) that are encountered by the RBC. * In the pulmonary capillaries the PO2 is high and therefore the amount of O2 bound to Hb is also high (fully saturated). In the systemic capillaries the PO2 is low and hence the O2 dissociates with the Hb and diffuses into the tissue cells. (The Hb is then said to be partially saturated). Although PO2 is the major factor in the binding of O2 to Hb, other factors also effect this process. * Acidity: Lactic acid and carbonic acid generated during exercise lowers the pH of the blood which promotes the release of O2 from Hb. Hence the exercising tissues which require extra O2 help create a situation where more O2 is available. * PCO2 effects the transport and delivery of O2. Increased metabolic activity of the tissue cells produces more CO2 as waste, which promotes release of O2 from Hb through an associated decrease in pH (see above point) and also as part of an O2/CO2 cycle. It goes something like this:
In the pulmonary capillaries, O2 diffuses from the alveolus into the RBC. It binds to Hb to create oxyhaemoglobin and H+ ions. Bicarbonate ions combine with the H+ ions to create carbonic acid which, under the influence of the enzyme carbonic anhydrase, dissociates into CO2 and water. The CO2 diffuses into the alveoli and is expelled by the lungs.
The RBC then travels in the blood to the systemic capillaries and CO2 diffuses from the tissues (as a waste product of tissue cell metabolism) into the RBC. A small percentage of the CO2 binds to the globin in Hb, forming carbaminohaemoglobin, this causes O2 to dissociate from the haem part of the Hb. The O2 then diffuses from the RBC into the tissue cells.
Most of the CO2, under the influence of the enzyme carbonic anhydrase, combines with H2O to become Carbonic acid which then dissociates into Bicarbonate ions (HCO3-) and H+ ions. The H+ ions promote the dissociation of O2 from the haemoglobin by taking the place of the O2 in the Hb molecule. * Increased temperature also has a minor effect of promoting the release of O2 from the Hb. Anatomy and physiology books such as "Anatomy and Physiology - From Science to Life" by Jenkins Kemnitz and Tortora is a fabulous resource for understanding the intricacies of this process.
