What is meant by Chromasia?

-chromasia combining form denoting staining or pigmentation.

What erythropoiesis means?

(eh-RITH-roh-poy-EE-sis) The formation of red blood cells in blood-forming tissue. In the early development of a fetus, erythropoiesis takes place in the yolk sac, spleen, and liver.

What is a reticulocyte?

Reticulocytes are newly produced, relatively immature red blood cells (RBCs). A reticulocyte count helps to determine the number and/or percentage of reticulocytes in the blood and is a reflection of recent bone marrow function or activity.

What is RBC and its function?

The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted. …

What is the most abundant component of blood plasma?

Sodium is the most abundant ion carried in plasma and contributes most of the plasma osmolarity.

What is a Polychromatophil?

The polychromatophil is an immature red blood cell which has already lost its nucleus. An elevated number of polychromatophils suggests an increased production of erythrocytes by the bone marrow (erythroid hyperplasia) in response to anemia.

Which is the largest blood cell?

Monocytes are the largest cells of the blood (averaging 15–18 μm in diameter), and they make up about 7 percent of the leukocytes.

What are the functions of blood?

Blood has many different functions, including:

• transporting oxygen and nutrients to the lungs and tissues.
• forming blood clots to prevent excess blood loss.
• carrying cells and antibodies that fight infection.
• bringing waste products to the kidneys and liver, which filter and clean the blood.
• regulating body temperature.

What happens if reticulocyte count is high?

High values A high reticulocyte count may mean more red blood cells are being made by the bone marrow. This can occur after a lot of bleeding, a move to a high altitude, or certain types of anemia.

How do you fix reticulocyte count?

Because the reticulocyte count is expressed as a percentage of total RBCs, it must be corrected according to the extent of anemia with the following formula: reticulocyte % × (patient Hct/normal Hct) = corrected reticulocyte count.

What is the main function of RBC?

What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.

What is the meaning of the word chromatic?

Who are the people who do chromasia training?

Chromasia Training is run by Libby and David Nightingale. Find out more about them here.

When do non cancerous cells show hyperchromasia?

A nucleus can show hyperchromasia for different reasons. Non-cancerous cells often show hyperchromasia when they are injured. Pathologists sometimes describe these cells as reactive. Some cancers are also made almost entirely of cells showing hyperchromasia. In this situation, the hyperchromasia used to support the diagnosis.
