Question

question 9
which component of blood is responsible for oxygen transport?
plasma
red blood cells
platelets
white blood cells
carbonic anhydrase

Explanation:

Red blood cells contain hemoglobin, which binds to oxygen and transports it throughout the body. Plasma is the liquid part of blood that transports nutrients, hormones, etc., but not oxygen. White blood cells are for immune function. Platelets are for blood clotting. Carbonic anhydrase is an enzyme (not a blood component in the context of the options' categorization here) that helps with carbon dioxide - related reactions.

Answer:

Red blood cells
