What is Breathing?
Breathing or respiration, is a process that involves the process of inhalation and exhalation of gases. It takes place in the lungs, where gaseous exchange occurs. Inhalation starts with the contraction of the diaphragm and intercostal muscles, which expands the chest cavity. Due to this, the pressure inside the lung decreases causing air to rush in. Oxygen is then transported to tissues through the bloodstream, while carbon dioxide, a metabolic waste product, is carried back to the lungs. Exhalation involves the relaxation of muscles, reducing lung volume, and expelling carbon dioxide.
Gas exchange in the lungs occurs in millions of small air sacs called alveoli. The breathing rate is the number of breaths taken per minute which is around 12 to 20 breaths per minute. It increases during running, or after exercise and decreases at rest.
Mechanism of BreathingFAQ’s – Mechanism of Breathing
Mechanism of Breathing is the process by which organisms inhale oxygen and release carbon dioxide. It involves the inhalation of air, where the diaphragm and intercostal muscles expand the chest cavity, allowing air to fill the lungs. During exhalation, the muscles relax, decreasing lung volume and expelling carbon dioxide. The respiratory center in the brainstem regulates this rhythmic cycle. The gaseous exchange takes place in the alveoli, where oxygen diffuses into the bloodstream, and carbon dioxide is released for removal.
Intrapleural breathing helps in maintaining respiratory efficiency. This rhythmic process ensures a continuous exchange of gases necessary for cellular function. In this article, we will discuss breathing, the mechanism of breathing, and Intrapleular breathing in detail.
