The question is asking about the major role of the skin. Here's a breakdown of each answer choice and an explanation of what they mean:
A. Retention of oxygen and excretion of carbon dioxide: This means that the skin would be responsible for holding on to oxygen and getting rid of carbon dioxide, which is not correct. The primary organs responsible for this function are the lungs.
B. Absorption of vitamin A and certain drugs: This means that the skin can absorb vitamin A and some drugs, meaning they can enter the body through the skin. This is true! The skin is capable of absorbing certain substances, including vitamin A and certain medications.
C. Storage of fatty tissue for energy: This means that the skin stores fatty tissue to be used as energy, which is not accurate. The skin does have a layer of fat beneath it, but its main role is not to store energy.
D. Synthesis and storage of proteins: This means that the skin is responsible for producing and storing proteins, which is not correct. While the skin does have proteins present in its structure, it is not the primary site for protein synthesis and storage.
Based on the options provided, the correct answer is B. The skin plays a major role in absorbing vitamin A and certain drugs.
