Formed Elements (table) Flashcards
-are commonly called red blood cells
-is a biconcave disk, thick around its rim and thin at its center. this shape gives the cell a greater surface area for an exchange of gases in the lungs and at the tissues.
Erythrocytes
Mainly, transport oxygen and carbon dioxide.
Erythrocytes
Have various functions, depending on type.
Leukocytes
Phagocytizes microorganisms.
Numbers increase in bacterial infections.
Neutrophil
Releases histamine to promote inflammation and heparin to prevent unnecessary clot formation. Numbers increase with allergies.
Basophil
Attacks some worm parasites.
Numbers can increase with allergies.
Eosinophil
Leaves the blood to become a macrophage in the tissues
Phagocytizes bacteria, dead cells, and other debris
Monocyte
Red, biconcave disks with no nucleus;
7.5 um in diameter
Erythrocytes
Spherical cells that must be stained to be seen
Leukocytes
Faint granules; nucleus with multiple lobes connected by a filament; stains pink to purple; 10-12 um in diameter
Neutrophil
Prominent granules that stain blue-purple; lobed nucleus; 10-12 um in diameter
Basophil
Prominent granules that stain orange to bright red; lobed nucleus; 11-14 pm in diameter
Eosinophil
Large cell, two to three times the size of an RBC; nucleus that is round, kidney-shaped, or horseshoe-shaped;
contains more cytoplasm than a lymphocyte; 12-20 um in diameter
Monocyte
Is important for the immune system.
Produces antibodies and other chemicals to fight foreign pathogens and is important for tumor control.
Lymphocyte
Form platelet plugs and release clotting factors
Thrombocytes
Cell fragments surrounded by a membrane; 2-4 um in diameter
Thrombocytes
Round nucleus with little cytoplasm;
6-14 um in diameter
Lymphocyte
cells and cell parts are called
