Answer 1

Humans use their respiratory system to inhale oxygen and exhale carbon dioxide. It also allows people to talk, laugh, and sing.

Major organs involved include the nose and mouth, nasal passages, trachea, bronchi (singular: bronchus), lungs, alveoli, and diaphragm.

The respiratory system has a close relationship with the circulatory system, oxygenating blood for tissues to survive and expelling carbon dioxide as waste.
