-How are capillaries organized?

A) Each arteriole narrows until it becomes a capillary, after which it increases in diameter to become a venule.

C) Capillaries branch off of arterioles to form a bed, or network, of many capillaries.
D) Capillaries branch into sinusoids where the exchange of nutrients and gases takes place.
