blood Flashcards
moves O2, CO2, nutrients, wastes, hormones, and stem cells through out body
transport function of blood
Inflammation, limit spread of infection, destroy microorganisms and cancer cells, neutralize toxins, and initiate clotting
protective function of blood
Fluid balance, stabilizes pH of ECF, and temperature control
regulative function of blood

thicker

blood is a _____ connective tissue
fluid
blood with all components
whole blood
liquid matrix of blood
plasma
cells and cell fragments of blood
formed elements
used to separate components of blood
centrifuge
heaviest and settles to the bottom in centrifuge
Red blood cells (erythrocytes)
thinner middle “buffy” layer in centrifuge. 1% of total volume
white blood cells and platelets
rises to top in centrifuge. 55% of total volume
plasma
Mix of water, proteins, nutrients, electrolytes, nitrogenous wastes, hormones, and gases
plasma
Makes up 46-63% of blood. Similar to interstitial fluid. Different types of proteins. Too large to leave vessels.
plasma
organ synthesizing most plasma proteins
liver
3 major plasma proteins
albumins, globulins, fibrinogen
Contributes to osmotic pressure of blood. Largest number of plasma proteins.
albumins
35% of plasma proteins and are antibodies. Transport- binds ions, hormones, lipids, and other compounds.
globulins
4% of plasma proteins. Form large strands of fibrin to make blood clots
fibrinogen
plasma is __% water
92
Lipids, amino acids, glucose, vitamins, cholesterol, and minerals
organic nutrients in plasma
Urea, uric acid, creatinine, bilirubin
organic wastes in plasma
