What is the blood pressure in the aorta? How does this compare with the pulmonary artery?
BP in the aorta is 120 mm Hg / 80 mm Hg, and normal pulmonary-artery pressure is about 14 mm Hg at rest. Outline the Starling forces in the pulmonary capillaries: Also known as Starling’s Law of Capillaries: Starling defined four variables for capillary circulation, namely, BHP, IFOP, BCOP and IFHP. BHP: Blood hydrostatic pressure is the pressure by which fluid flows toward the outside of capillaries. Remember, fluids don’t want to “move”, so when blood is flowing through capillaries, fluid tends to move outward into the interstitial space. BHP ~ 35 mm Hg. IFOP: Interstitial fluid osmotic pressure is the pressure by which interstitial space (with the help of interstitial proteins, ions, etc.) pulls out fluid from the capillaries. Because there are not many proteins, ions, etc. in interstitial space, IFOP ~ 1 mm Hg. IFHP: Interstitial fluid hydrostatic pressure is the pressure by which fluid flows toward the inside of capillaries. However, since interstitial fluid is already at rest, in
