Which of the following is not transferred by alveoli?

Step 1: Define the Problem

Identify what alveoli transfer and determine which option is not part of this process.

Step 2: Break Down the Problem

1. Understand the function of alveoli in the respiratory system.
2. List the substances typically transferred by alveoli.

Step 3: Apply Relevant Concepts

Alveoli are tiny air sacs in the lungs where the exchange of gases occurs. They primarily transfer:

• Oxygen from the air to the blood.
• Carbon dioxide from the blood to the air.

Step 4: Analysis, Verify and Summarize

Analyze the options provided in the question to determine which substance is not typically transferred by alveoli.

Final Answer

The substance that is not transferred by alveoli is nutrients. Alveoli are involved in gas exchange, not nutrient transfer.
