which of the following processes move substances across capillary walls

• vesicular transport

• diffusion

• filtration

• reabsorption

• all of the above are responsible for moving substances across capillary walls

blood colloid osmotic pressure is largely due to _______

• the proteins in the blood, and it promotes reabsorption

• the proteins in the blood, and it promotes filtration

• the high amount of water in the blood, and it promotes diffusion out of the capillaries

• the high amount of water in the blood, and it promotes filtration from arterioles

• the pressure generated by the heart, and it favors osmosis into the arteriole end of the capillary bed

which of the following cartilages is largest

• corniculate cartilage

• epiglottic cartilage

• cricoid cartilage

• thyroid cartilage

• arytenoid cartilage

excitation of the vasomotor center results in ________

• increased parasympathetic activity and predominantly more vasodilation than vasoconstriction

• increased sympathetic activity and predominantly more vasoconstriction than vasodilation

• decreased autonomic activity that decreases heart rate and constricts blood vessels

• increased autonomic activity that increases heart rate and dilates blood vessels
