When you get a paper cut on your thumb, are you cutting into an artery, a vein or a capillary

It would be a capillary because capillaries in your hands and fingers are closely packed together, meaning paper cuts can cause a lot of bleeding because of how concentrated blood can be in your hands.

Singular third person pronouns are “he,” “she,” “it,” “his,” “hers,” “him” and “her,” and third person plural pronouns are “they,” “them” and “their.” the number of people to which you are referring should always match the pronoun you choose (“he” to refer to one male, “they” to refer to more than one male).
