Verified step by step guidance

Understand the anatomy of the respiratory system: The respiratory system is composed of several structures including the trachea, bronchi, bronchioles, and alveoli.

Identify the function of each structure: The trachea is the windpipe that connects the larynx to the bronchi. The bronchi are the main passageways into the lungs, and they branch into smaller bronchioles.

Recognize the role of alveoli: Alveoli are tiny air sacs located at the end of the bronchioles. They are crucial for gas exchange, allowing oxygen to enter the blood and carbon dioxide to be expelled.

Visualize the structure: Imagine the respiratory tree, where the trachea is the trunk, bronchi are the branches, bronchioles are the twigs, and alveoli are the leaves or clusters at the end.

Conclude with the correct identification: Based on the description of 'very small grape-like clusters found at the end of each bronchiole,' the correct answer is alveoli.
