Red blood cells (RBCs), also called erythrocytes are the most common type of blood cell and the vertebrate organism’s principal means of delivering oxygen (O2) to the body tissues-via blood flow through the circulatory system.
Red blood cells take up oxygen in the lungs or gills and release it into tissues while squeezing through the body’s capillaries.
The cytoplasm of a red blood cell is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells.
In humans, mature red blood cells are flexible and oval biconcave disks. They lack a cell nucleus and most organelles, in order to accommodate maximum space for hemoglobin.
Approximately 2.4 million new red blood cells are produced per second in human adults.
The cells develop in the bone marrow and circulate for about 100-120 days in the body before their components are recycled by macrophages. Each circulation takes about 20 seconds. Approximately a quarter of the cells in the human body are red blood cells.
I will now show a transition of videoclips of red blood cells from low magnification to high magnification: (40x to 100x to 400x).
