Question

Inhalation of a poison​ causes:

A. absorption by the trachea.
B. absorption in the alveolar capillary.
C. aspiration.
D. increase in secretions.

Answer 1

Inhalation of a poison can cause absorption in the alveolar capillary, where the poison enters the bloodstream through the thin walls of the alveoli and is distributed throughout the body.

Step-by-step explanation:

Inhalation of a poison can cause absorption in the alveolar capillary. When a poison is inhaled, it can enter the bloodstream through the thin walls of the alveoli, which are tiny air sacs in the lungs surrounded by capillaries. This allows the poison to be rapidly distributed throughout the body.

For example, if someone inhales carbon monoxide, it can be absorbed into the bloodstream through the alveoli. Carbon monoxide binds to hemoglobin in red blood cells, preventing them from carrying oxygen effectively and leading to oxygen deprivation in the body.
