Blood carries substances to the cells by putting them into the interstitial fluid so it is the _____
Transport- oxygen, nutrients, waste
Protection- clotting, immunity = white blood cells (WBC), interferon, complement
are all Functions of __________
Characteristics of blood:
Alkaline: 7.4 pH avg.
8 % of body weight (if you weighted 100 pounds, and lost all your blood you would lose 8 pounds)
Blood volume: 1.2 gallon female, 1.5 gallon male
Temperature of the blood is a little higher then body temperature, WHY?
Red blood cells, white blood cells
Cells of the blood are mostly _____ (RBCs). The rest, only 1%, is basically platelets and ____ (WBCs)
Centrifuging blood forces cells to separate from plasma.
Hematocrit is the % of total volume of cells
Normal crit = females ____ avg., males ___ avg.
white blood cell
What is in the buffy coat __ __ __s after Centrifuging blood forces cells to separate from plasma?
Mature RBCs are called _______ (red, cells)
Contains oxygen-carrying protein called hemoglobin. Anatomy- 7.5 microns, biconcave disc- can get into small places. Gets energy anaerobically So it doesn't need the oxygen that it's carrying.
__________count ("Tic") measures the rate of erythropoiesis and so can give an indication of RBC creation.
membrane fragility -- lysis in narrow channels in the spleen through a process called ____________
_______ is a form of hypoxia due to obstruction of blood flow, some diseases related to hypoxia: stroke, trauma, heart attack, multiple organ failures, cancer, respiratory diseases, and hemorrhagic stroke.
Neutrophils, Eosinophils, Basophiles
are all _________, and White blood cells (leukocytes ). These types stain.
Lymphocytes, and Monocytes are all _________, and White blood cells (leukocytes ). And do not stain.
Circulating WBCs do not stay in bloodstream
granulocytes leave in 8 hours
monocytes leave and transform into macrophages
WBCs provide long-term ______lasting decades to fight off invaders*
This cell stains Reddish to violet granules in cytoplasm.
Older neutrophils are called polymorphonuclear (PMN) leukocytes or "POLYS"
(increase in bacterial infections)
*phagocytosis of bacteria
releases antimicrobial chemicals*
(increase in parasitic infections or allergies)
phagocytosis of antigen-antibody complexes, allergens & inflammatory chemicals
release enzymes destroy parasites such as worms
(increase in chicken pox, sinusitis, diabetes)
*secrete histamine (vasodilator)
secrete heparin (anticoagulant)*
the cops of the body
The blood is a transport system (cop car) for monocytes as they fight infection in tissues
They go into tissue and become macrophages (macro= big, phage= eater)
