Patm Correct Answer: 760 mm Hg (mercury)
PN2 (partial pressure of nitrogen in air) Correct Answer: Patm * PN2 (760 * 0.78) = 592.8 mm Hg
PO2 (partial pressure of oxygen in air) Correct Answer: Patm * PO2 (760 *

Patm Correct Answer: 760 mm Hg (mercury)
PN2 (partial pressure of nitrogen in air) Correct Answer: Patm * PN2 (760 * 0.78) = 592.8 mm Hg
PO2 (partial pressure of oxygen in air) Correct Answer: Patm * PO2 (760 * 0.21) = 160 mm Hg
Alveolus Correct Answer: tiny air sacs of lungs which allow for rapid gas exchange
Atmospheric pressure Correct Answer: pressure exerted by weight of atmosphere
Boyle's Law Correct Answer: P x V = k. Inverse relationship between pressure and volume for fixed amount of gas at constant temperature. Pressure * Volume = Constant K
Capillaries Correct Answer: tiny, branching blood vessels that form a network between arterioles and venules
Hemoglobin (Hgb) Correct Answer: protein in blood cell that binds O2. Normal level: 12 g/dL. iron rich protein that helps RBCs carry O2 from lungs to rest of body. 1g of Hgb carries 1.39 mL
Partial Pressure Correct Answer: pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own
Partial pressure of a gas dissolved in liquid Correct Answer: = partial pressure in air above water
Pgas Correct Answer: = Fgas (friction of gas) x Ptotal
Dalton's law Correct Answer: Ptotal = P1 + ... + Pn. In a mix of non-reacting gases, the total pressure exerted = sum of partial pressures of individual gases
Total Oxygen in Blood Correct Answer: = O2 dissolved + O2 bound to hemoglobin
Kidneys Correct Answer: conserve water, filter toxins or byproducts of metabolism, getting rid of excess dietary fluid and salt
Concentration gradient Correct Answer: gradual change in concentration of solutes present in a solution between 2 regions
Dialysate Correct Answer: part of mixture which passes through membrane in dialysis. Solution of pure water, electrolytes, and salt, like bicarbonate and sodium
Dialysis kidney Correct Answer: process of removing waste products and excess fluid from body
Edema Correct Answer: puffiness caused by excess fluid trapped in body's tissues. Increased hydrostatic pressure, decreased oncotic pressure
extracellular space Correct Answer: intravascular + intrastitial space. 1/3 of body.
glomerulus Correct Answer: cluster of nerve endings, spores, or small blood vessels (cluster of capillaries around end of kidney tubule), where waste products are filtered from blood
hydrostatic force/pressure Correct Answer: fluid pressure. water moves from high hydrostatic pressure to low hydrostatic pressure
