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
Pulmonary parenchyma is a term for lung tissue, including bronchioles, interstitium and alveoli, reports Radiopaedia.org. The function of the parenchyma in the lungs is to exchange oxygen and carbon dioxide.Full Answer >
The type of muscles that control the size of the bronchioles in the lungs are known as smooth muscles. Smooth muscles are found in both walls of the bronchioles and arterioles located in both lungs. They happen to be the only kind of muscle found in the lungs.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 >
The stimulus threshold is the minimum change in a sensory stimulus that can be detected at least half of the time. Sensory receptor cells detect stimuli and changes of stimuli from the outside world and translate them into electrical signals that the brain can interpret.Full Answer >
