Which four body systems interact to allow a person to sneeze? A) Muscular, immune, nervous, respiratory B) Nervous, respiratory, circulatory, skeletal C) Respiratory, endocrine, skeletal, circulatory D) Lymphatic, skeletal, respiratory, muscular

The four body systems that interact to allow a person to sneeze are the muscular system, immune system, nervous system, respiratory system (Option A).

• Sneezing can be defined as an involuntary expulsion of air that helps to remove irritant particles from the nose and/or throat.

• In the first place, the brain (i.e., the nervous system), when the respiratory epithelium (i.e., the respiratory system) is irritated, the endings of the cranial nerve sends a signal message to the brain to induce a sneeze reflex.

• The muscles involved in sneezing include the chest muscles, abdominal muscles, diaphragm, and muscles that control vocal cords.

• Sneezing is a fundamental immune response aimed at clearing the respiratory system of harmful pathogenic microorganisms (e.g. bacteria) and viruses.

In conclusion, the body systems that interact to allow a person to sneeze are the muscular system, immune system, nervous system, respiratory system (Option A is correct).

Answer:

A

Explanation:

Muscular, immune, nervous and respiratory systems are involved in the process of sneezing. Sneezing is the natural defense mechanism of the human body. When any foreign particle enters the respiratory system then it irritates the respiratory epithelium and sends a signal to the brain through the 5th trigeminal nerve and sneezing reflex starts which involved skeleton muscles and respiratory system.
