- If protein concentration decreases (due to malnutrition), net flow of fluid out of capillaries would INCREASE - Deprivation of glucose in blood: bad for the body - Adrenal gland hormones: disassemble the muscles (proteins break down, releasing amino acids, and converted to glucose by the liver) gluconeogenesis Blood - Ca2+ and H+ must be strictly maintained o Too much Calcium: excitable cells’ activity is suppressed to the point at which slightly elevated calcium level results in slowed heart rate/activity - pH of H+/HCO 3 - is balanced out at 7.4 o –NaHCO3 buffer is the most rapid, with the lowest capacity

Unformatted text preview: o –Respiratory System o Kidney, slowest and highest capacity-Albumin: protein o (when in abundance, exerts osmotic pressure) o Can bind many lipophillic hormones -Platelets: fragments of cells-Time = (distance) 2 Gas exchange:-Gas molecules move by diffusion, so there must be a concentration gradient-Air: mostly Nitrogen, some Oxygen, CO2, H2O-Surfactant in the alveoli: reduces the surface tension; preventing alveoli from shrinking/contracting-Premature babies have breathing problems because they have trouble inflating their lungs and nothing flows the way it should...
