Erythrocyte
|
|
Erythrocyte An erythrocyte is more commonly known as a red blood cell, which is the most numerous type of blood cell. Erythrocytes contain the red pigment hemoglobin and are responsible for oxygen transport. In humans, the number of erythrocytes in the blood varies between 4.5 and 5.5 million per cubic millimeter. They survive for about four months and are then destroyed in the spleen and liver.

In humans, the number of erythrocytes in the blood varies between 4.5 and 5.5 million per cubic millimeter. They survive for about four months and are then destroyed in the spleen and liver.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Cell
Fundamental structural unit of all life. The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.
Hemoglobin
Hemoglobin is a substance contained within the red blood cells and is responsible for their color. It has the unique property of combining reversibly with oxygen and is the medium by which oxygen is transported within the body. It takes up oxygen as blood passes through the lungs and releases it as blood passes through the tissues.
Oxygen
A chemical element essential for sustaining life.
Spleen
The organ that cleans blood and makes white blood cells.
Liver
The largest organ in the body. The liver carries out many important functions, such as making bile, changing food into energy, and cleaning alcohol and poisons from the blood.

Reddish discoloration and swelling of the limbs in response to cold. Erythrocyanosis is particularly common in children and more common in women than men.
Erythrocyte (red blood cell, red cell, red corpuscle)
Red blood cell that delivers oxygen to tissues and removes carbon dioxide and other waste products.
Erythrocyte sedimentation rate
blood test that measures the speed at which red blood cells settle on the bottom of a test tube; high sedimentation rate signals possible inflammatory disease.
Erythrodermic psoriasis
A particularly inflammatory form of psoriasis that often affects most of the body surface. It is the least common form of psoriasis and most commonly appears on people who have unstable plaque psoriasis, where lesions are not clearly defined. The erythrodermic form of psoriasis is characterized by periodic, widespread, fiery redness of the skin. The erythema (reddening) and exfoliation (shedding) of the skin are often accompanied by severe itching and pain. Swelling may also develop.
Erythroleukemia
A form of acute myeloid leukemia (AML) involving the cells that give rise to the erythrocytes (the red blood cells). In this type of leukemia, the body produces large numbers of abnormal, immature red blood cells. Erythroleukemia is classified as acute nonlymphocytic leukemia (ANLL) of the M6 type.
Erythromycin
An antibiotic derived from the bacterium Streptomyces erythreus which is especially effective against gram positive bacteria. This antibiotic is often used to treat people who are allergic to penicillin, to treat penicillin-resistant infections and acne.

Erythrophobia
An abnormal and persistent fear of blushing. Sufferers of erythrophobia experience undue anxiety even though they realize their fear is irrational. Their anxiety results from worry about being the focus of attention and the subject of embarrassment. Attempts to suppress blushing often have the opposite effect. Sufferers of erythrophobia tend to avoid social gatherings and workplace projects that require them to interact with, or speak before, groups of co-workers.
Erythroplakia
A reddened patch with a velvety surface found in the mouth.
Erythropoiesis
The formation of red blood cells.
Erythropoietin (EPO)
A hormone produced by the kidney that promotes the formation of red blood cells in the bone marrow. EPO is a glycoprotein (a protein with a sugar attached to it). Human EPO has a molecular weight of 34,000.
Erythropoietin test
A test of the hormone erythropoietin (EPO) in blood. An abnormal level of EPO may mean bone marrow or kidney disease or EPO abuse.
PREVIOUS AND NEXT TERMS--------------------------------------
Epithelium
A thin layer of cells that covers the internal and external surfaces of the body, including body cavities, ducts and vessels.
Erythrocyte
Ejaculation
Ejaculation is the process of ejecting semen from the penis, and is usually accompanied by orgasm as a result of sexual stimulation. It may also occur spontaneously during sleep (called a nocturnal emission), due to stimulating of the prostate or, rarely, due to prostatic disease.
Eukaryotic
The living world is divided into two classes of organism. Eukaryotic and, much simpler, prokaryotic organisms such as bacteria. Generally eukaryotes are diploid and their cells have internal organelles, such as nuclei. Prokaryotes are haploid with much simpler cells.
Enzyme
A cellular protein whose shape allows it to hold together several other molecules in close proximity to each other. In this way, enzymes are able to induce chemical reactions in other substances with little expenditure of energy and without being changed themselves. Basically, an enzyme acts as a catalyst.
Eicosanoid
A hormone derived from a polyunsaturated fat. Eicosanoids are made by every cell in the body. As autocrine hormones, they are constantly produced by the cell to sample the external environment. "Good" eicosanoids generate AMP.
