All about Blood Cells
Red Blood Cell
Red blood cells, or erythrocytes, contain the hemoglobin that carries oxygen and carbon dioxide around the body. (Erythro means red in Greek, and cyte translates to cell.) Hemoglobin gives red blood cells their Characteristic color. When it is oxygen-rich, it appears reddish; when oxygen-poor, it is darker and bluish.
Although erythrocytes are flexible (which permits them to squeeze through capillaries), they typically have a distinctive biconcave shape that helps maximize surface area to facilitate the exchange of gases.
White Blood Cell
White blood cells, or Leukocytes, are your body’s white knights. If an enemy germ invades you, they ride to the rescue and fight to the death.
There are several different kinds of leukocytes, and each has special skills to help protect you. Neutrophils race to the scene when bacteria attack. B cells neutralize viruses and T cells move in for the coup de grâce.
Plasma is the pale liquid that makes up about 55% of your blood. The other blood components are suspended in plasma, and it allows them to travel through the blood vessels and around your body!
Plasma itself plays a critical role in carrying waste products to the kidneys, liver, and lungs where they can be removed from the body. Plasma also helps maintain normal blood pressure and helps regulate the body’s temperature.
Platelets, or thrombocytes, are the smallest cells (or cell fragments) in the blood. Under the microscope, they normally look like little disks, or plates!
The primary purpose of platelets is to prevent bleeding by creating blood clots, and the average person has between 150,000 to 400,000 platelets in every drop (or microliter) of blood.
Antibodies are Y-shaped proteins produced by the body’s immune system to help identify foreign interlopers such as viruses, bacteria, or toxic chemicals.
While the bodies of antibodies come in a few specific types (or isotypes), the tips (or paratopes) can be custom made, like a lock to a key, to attach only to specific parts (or epitopes) of an antigen. There are more than 10 billion combinations to this lock!
