Answer:
"Hem-" is a prefix derived from the Greek word "haima," which means blood.
Step-by-step explanation:
The breakdown of the word parts in the term "hemarthrosis" is as follows:
"Hem-" is a prefix derived from the Greek word "haima," which means blood.
"-arthr-" is the combining form derived from the Greek word "arthron," which means joint.
"-osis" is a suffix derived from the Greek word "-osis," which denotes a condition or state.
Therefore, the breakdown of the word parts in "hemarthrosis" is:
Hem- + -arthr- + -osis
This term refers to a condition characterized by bleeding into a joint, specifically the presence of blood in a joint cavity.
