1. during respiration,

, and
are produced.

Explanation:

1. Cellular respiration requires oxygen, which is taken in by the respiratory system.
2. Hairs and fluid (mucus) in the nose trap dirt and particles during inhalation.
3. Gas exchange in the lungs occurs between blood and alveoli.
4. Alveoli are surrounded by capillaries.
5. The heart is the muscular organ that drives the circulatory system.
6. The main blood vessels in the circulatory system are arteries and veins.
7. Ingestion, digestion, absorption, and elimination are the four tasks of the digestive system.
8. For cellular respiration, glucose and oxygen are required.
9. During respiration, carbon dioxide, water, and usable energy are produced.
