Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing hemoglobin whose function is to transport oxygen.
Red blood cells that contain the protein hemoglobin, which is the site where oxygen is carried in the blood.
Hemoglobin-containing cells (manufactured in the bone marrow) that transport the oxygen from the lungs to the body tissues where it is needed.
Red blood cells formed in red bone marrow.
The red blood cells, leukocytes.
Mature red blood cell. The function of this nonnucleated, biconcave disk containing hemoglobin is to transport oxygen.
Mature red blood cell (RBC), which contains the pigment hemoglobin, the main function of which is to transport oxygen to the tissues of the body. A red blood cell is a biconcave disc with no nucleus. It is the main cellular element in the blood; in 1 cubic milliliter of blood there are usually 4,500,000- 5,000,000 erythrocytes in males, 4,000,000-,500,000 in females.
A red blood cell. The erythrocyte is rich in hemoglobin, a protein that binds easily with oxygen and serves to transport it through the blood. Erythrocytes form in the bone marrow where they lose their nuclei before passing into the bloodstream, meaning that they cannot reproduce. Erythrocytes have a life span of about 120 days, after which they break down in the spleen and are destroyed.
A blood cell containing the pigment hemoglobin, the principal function of which is the transport of oxygen. A mature erythrocyle has no nucleus and its shape is that of a biconcave disk, approximately 7 μm in diameter. There are normally about 5 x 10¹² erythrocytes per liter of blood.
The biconcave red blood cells that carry oxygen from the lungs to the tissues, and return carbon dioxide. They have an excess of membrane, some of which may be lost in various disorders, as a result of which they become progressively more spherical and rigid. Erythrocytes, which have no nuclei, are formed during erythropoeisis from erythroblast cells in the bone marrow, and each mm³ of blood contains 5 million of them. They are by far the largest constituent among the blood cells and they contain large amounts of the oxygen carrier haemoglobin They have a life of about 120 days after which they are absorbed by macrophages, the blood’s scavenging cells. Most components of the erythrocytes, including the red pigment haemoglobin, are reused, though some of the pigment is broken down to the waste product bilirubin.
Red blood cells, also referred to as erythrocytes or red blood corpuscles, play a vital role in the bloodstream. These essential blood components are primarily responsible for transporting oxygen to various tissues throughout the body and facilitating the removal of carbon dioxide from those tissues.
