question 30

a catheter is a tube inserted into a vessel. when we add the suffi
it describes the process of placing a catheter in a vessel.

-ion
-ization
-rrhaphy
-emia

Explanation:

• For the first question: The word root "ventricle" comes from Latin. In medical terminology, it refers to one of the pumping chambers of the heart. The term "little belly" (venter in Latin) is related to its etymology. The heart chamber where blood first enters is the atrium. A hat - related meaning is not relevant to the medical word root. A large vessel leading from the heart is an artery (e.g., aorta).
• For the second question:
• The suffix “-ion” is used to form nouns denoting an action or process. “Catheterization” is the process of placing a catheter.
• The suffix “-ization” means the action or process of becoming or making. But “catheterization” is the more specific medical term for the process of placing a catheter.
• The suffix “-rrhaphy” means suturing (e.g., herniorrhaphy - suturing of a hernia).
• The suffix “-emia” means a condition of the blood (e.g., anemia - lack of red blood cells).

Answer:

• First question: "little belly"; one of the pumping chambers of the heart
• Second question: -ization
