Definitions Flashcards
Receptor:
DETECTS STIMULI
Half-life:
AMOUNT OF TIME IT TAKES FOR BLOOD CONCENTRATION OF A HORMONE TO BE REDUCED TO HALF OF THE ORIGINAL AMOUNT RELEASED
EPO:
HORMONE (MADE MAINLY BY KIDNEYS); INCREASES RATE OF PRODUCTION OF ERYTHROCYTES
Infundibulum:
PHYSICAL CONNECTION BETWEEN HYPOTHALAMUS & PITUITARY GLAND
Isthmus:
CONNECTION BETWEEN THE RIGHT & LEFT LOBE OF THYROID
Agglutination:
PROCESS OF CELLS CLUMPING DUE TO CROSS-LINKING BY ANTIBODIES
Diapedesis:
PASSAGE OF LEUKOCYTES THRU BLOOD VESSEL WALLS
Chemotaxis:
PROCESS THAT ATTRACTS LEUKOCYTES TO SPECIFIC AREAS
Centrifuge (and understand what it does):
DEVICE THAT SEPARATES BLOOD COMPONENTS BY SPINNING (USED IN PHLEBOTOMY)
Hemopoiesis:
MAKES NEW FORMED ELEMENTS
Hemoglobin:
PROTEIN, ALLOWS OXYGEN TO BIND
Erythrocyte:
RED BLOOD CELLS
Leukocyte:
WHITE BLOOD CELLS
Megakaryocytes:
PRODUCES PLATELETS
Vasoconstriction & Vasodilation (and how do these contribute to temperature regulation?):
VASOCONSTRICTION: LESS HEAT LOSS. VASODILATION: MORE HEAT LOSS
