Answer:
The two body systems that interact to produce inhalation in humans are respiratory and muscular systems (option A).
Explanation:
Inhalation is the first phase of the breathing process, which depends on the respiratory system and consists of the entry of air into the lungs.
The process of inhalation implies a mechanical work to overcome the negative intrathoracic pressure, allowing the entrance of air. This work is done by the diaphragm, external and internal intercostal muscles and the abdominal muscles.
For this reason inhalation depends on the interaction of the respiratory and muscular systems.
