What is petechiae? a. excessive fluid in tissues b. rupture of veins c. rupture of arteries d. weakness of capillaries

I think the answer is the letter B

I would say D.

Tiny round brown-purple spots due to bleeding under the skin, may be in a small area due to minor trauma or widespread due to blood-clotting disorder.

Capillaries are tiny blood vessels in the body’s tissues in which the exchange of oxygen and carbon dioxide take place.

I'd say 8. i'd u don't so what u should u don't get what u want.
