Smaller tubes within the lungs; Made up of spongy, elastic tissue that stretches as you breathe; Which of the following structure is where cellular respiration occurs in the cell?
Understand the Problem
The questions are asking about anatomy and cellular biology, specifically focusing on respiratory structures and the site of cellular respiration. It is essential to understand the roles of various components in the lungs and cells.
Answer
Bronchioles, Alveoli, Mitochondria
The final answer is bronchioles for the smaller tubes, alveoli for the spongy tissue, and mitochondria for cellular respiration.
Answer for screen readers
The final answer is bronchioles for the smaller tubes, alveoli for the spongy tissue, and mitochondria for cellular respiration.
More Information
The bronchioles are the smaller tubes in the lungs, leading to alveoli, which have elastic walls that facilitate breathing. Cellular respiration occurs in mitochondria, the powerhouse of the cell.
Tips
Confusing bronchioles with alveoli or bronchi is common; remember that bronchioles are smaller branches of the respiratory system leading to alveoli.
