Document Summary

40 pre midterm 60 post midterm. all multiple choice, some t or f and some fill in the blanks. The lungs and kidneys regulate blood acid/base balance by independently controlling 2 major (cid:272)o(cid:373)po(cid:374)e(cid:374)ts of the (cid:271)ody"s (cid:373)ajor (cid:271)ufferi(cid:374)g syste(cid:373: co2 in the lungs and hco3 in the kidneys. Buffers: substance that reversibly consumes or releases h: minimizes ph changes. Balance depends on the lungs and kidneys. There are also ammonia, ammonium and phosphate buffers: more unbound acid will shift the equilibrium of acids and conjugate base toward the conjugate base. The most important physiological buffer pair is co2 and. There is an eq between co2 and bicarbonate in the ecf. Carbonic anhydride converse co2 and h2o to h+ and hco3. Increase in co2 shifts the eq to the right, meaning the blood becomes more acidic change in diffusion distance can be caused by edema in the lungs, causing respiratory alkalosis.
