Question

1. Surfactant is needed to

decrease blood flow to well oxygenated alveoli

reduce friction between the lungs and the walls of the thoracic cavity

increase blood flow to well oxygenated alveoli

facilitate the movement of gases across the alveolar cells

reduce surface tension which opposes the expansion of the lungs

2. Glomerular filtration is driven by

contraction of Bowman's capsule

contraction of the afferent arteriole and glomerulus

active transport

blood pressure in the glomerulus

osmosis

3. The pleural sac

accumulates in lungs in congestive heart failure

stimulates red blood cell production

lubricates movement of the lungs

activates the extrinsic pathway of blood coagulation

removes particulates from the airway epithelium

4. As blood flows through a capillary,

hydrostatic pressure is the same at both ends of the capillary

colloid osmotic pressure is greater at the venous end than at the arterial end

colloid osmotic pressure is greater at the arterial end than at the venous end

hydrostatic pressure is greater at the arterial end than at the venous end

hydrostatic pressure is greater at the venous end than at the arterial end
