Part 2 Flashcards
How long are lymphocytes able to live for?
They are able to live for YEARS. Most other blood cells live for hours, days, or weeks
The number of red blood cells and platelets remains steady while that of white blood cells
Varies depending on invading pathogens and other foreign antigens
The process of producing blood cells is
Hemopoiesis(hematopoiesis)
Red blood cells (erythrocytes) contain the protein
Hemoglobin
Function of hemoglobin
Used to carry oxygen to all cells and to carry some carbon dioxide to the lungs
Each hemoglobin molecule contains an iron ion which allows each molecule to bind to
Four oxygen molecules
Red blood cells have no nucleus or other organelles and are
Bioncave discs
Bioncave discs allow red blood cells to carry
Oxygen efficiently
Hemoglobin is involved in
Regulating blood flow and blood pressure via the release of nitric oxide (NO)
Nitric oxide causes vasodilation, this
Improves blood flow and enhances oxygen delivery
Red blood cells also contain carbonic anhydrase
Which catalyzes the conversion of carbon dioxide and water to carbonic acid
Carbonic acid transports about ______ of Carbon dioxide and water to carbonic acid
70%
Red blood cells can live for only about
120 days
Dead blood cells are removed from the circulation by the
Spleen and liver
What happens to breakdown products from the red blood cells?
They are recycled and reused
