Summary Introduction

To write:

The effects on the organs of the body when the smooth muscles in the bronchioles constrict, causing breathing to be difficult.

Introduction:

In bronchioles, the condition in which the smooth muscles of the bronchus contracts. It is controlled by the parasympathetic nervous system. Antigens, asthma, and inflammatory responses thus narrowing the bronchioles, and reducing air flow and reduce oxygen exchange. Such constriction is a protective mechanism for the respiratory system.

Explanation of Solution

The condition in which the smooth muscles of the bronchus contracts is controlled by the parasympathetic nervous system. Antigens, asthma, and inflammatory responses thus narrowing the bronchioles, and reducing air flow and reduce oxygen exchange. Such constriction is a protective mechanism for the respiratory system. Smooth muscles usually contract the bronchi when they contract and dilate the bronchi when they relax and this is mostly a protective feature since it allows regulation of the amount of air that can enters the lungs. Antigens, asthma, and inflammatory responses thus narrowing the bronchioles, and reducing air flow and reduce oxygen exchange. Such constriction is a protective mechanism for the respiratory system.
