The primary stimulus for breathing is the bronchioles in the lungs reacting to a build-up of carbon dioxide. When carbon dioxide levels are too high, the body reacts by taking in oxygen and expelling carbon dioxide.Know More
Breathing can be manually controlled by the body to a point. When carbon dioxide levels rise too high and reach the medulla oblongata, the body involuntarily takes a breath. Cellular respiration produces carbon dioxide at a faster rate than oxygen production. This causes the lungs to respond through increased ventilation, providing an additional oxygen supply.
Carotid bodies in the carotid artery respond to changes in environmental oxygen loss when the carbon dioxide levels remain unchanged. They help regulate breathing to provide the necessary amount of oxygen to survive in oxygen-sparse environments.Learn more about Zoology
A paradoxical bronchospasm is the constriction of the bronchioles that occurs after a person uses an inhalant intended to reduce the symptoms of COPD or asthma. The reaction is the opposite of the intended reaction, because the medication that triggers the bronchospasm is meant to dilate the bronchioles.Full Answer >
Bronchiolitis obliterans with organizing pneumonia, or BOOP, is inflammation and clogging of the bronchioles, alveoli and the small bronchi walls with connective tissue, according to Mayo Clinic. This condition only occurs in rare cases.Full Answer >
The University of Southern California Keck School of Medicine describes the bronchioles as hollow structures that allow air to travel in and out of the lungs. The four types of passageways in the lungs are the trachea, bronchus, bronchi and bronchioles.Full Answer >
Clara cells are dome-shaped cells found in the bronchioles of the lungs that have short microvilli. Clara cells are also known as bronchiolar exocrine cells.Full Answer >
