which of the following is not a function of the respiratory system?
assists with homeostasis of body ph
distributes oxygen to cells
filters air
warms air

Explanation:

To determine the non - function of the respiratory system, we analyze each option:

1. Assists with homeostasis of body pH: The respiratory system can adjust the levels of carbon dioxide (and thus carbonic acid) in the blood, which helps maintain blood pH. So this is a function of the respiratory system.
2. Distributes oxygen to cells: The respiratory system is responsible for bringing oxygen into the body and getting it to the alveoli. However, the distribution of oxygen to the cells is mainly the job of the circulatory system (the blood, pumped by the heart, carries oxygen to the cells).
3. Filters air: The respiratory system has structures like the nasal cavity with cilia and mucus that filter out dust, pollen, and other particles from the incoming air. So this is a function of the respiratory system.
4. Warms air: The nasal cavity and other upper respiratory tract structures warm the incoming air to body temperature. So this is a function of the respiratory system.

Answer:

B. Distributes oxygen to cells (assuming the options are labeled A - D in order: A. Assists with homeostasis of body pH, B. Distributes oxygen to cells, C. Filters air, D. Warms air)
