Respiration is an important process for the survival of all living beings on earth. While all terrestrial vertebrates breathe exclusively through lungs, some species of amphibians can switch to using their skin to breathe while underwater, and some do not use lungs at all. They have various other modes of respiration like plasma membrane, gills, skin, trachea, etc. Pulmonology specializes in the mode of respiration that takes place through the lungs and the various maladies that can ail each of the organs involved in the process. The term may sound simple, but if we look at the studies and researches that go on involving the organs, their anatomy, physiology, and functions, we find that the underlying concepts are surprisingly vast. Owing to this extensiveness of curriculum, students often look for Pulmonology academic assistance through online tutoring, and rightfully so!
According to our Pulmonology homework help experts, some important organs that play a part in our breathing are the nose, trachea, lungs, and diaphragm. In the simplest explanation of the events, we breathe when air enters and exits our body through the nasal cavity. The fine hair-like structures inside the nose called cilia lock in all the dirt particles and stops them from entering the lungs. Parallelly, the mucous secreted inside keeps the passage moist and also regulates the temperature of the air that flows inside. But that is not all; pulmonary respiration is a complex process that involves multiple steps for its completion, and our Academic Writing Help specialists explain them all.
The pulmonary system is a network of tissues and organs that help us breathe. It includes the organs of the airways like the larynx, trachea, lungs, bronchioles, alveoli, capillaries, and blood vessels. The muscles that control our lungs are also a component of the pulmonary system. All these organs function in tandem to circulate oxygen throughout our body and eliminate the waste byproduct as carbon dioxide.
As we inhale air, it rapidly travels to the pharynx or throat. From there, it proceeds through the larynx to go into the trachea. Inside the lungs, the trachea cleaves into two to form the left and right bronchus. They each then progressively split into thin, branching filaments called bronchioles. The smallest of the bronchioles culminate in tiny, round sacs of air and are called the alveoli. Alveoli are grape-like structures that inflate when we inhale and deflate when we exhale.
Through a complex biochemical process, the alveolar sacs release oxygen into the bloodstream and absorb the carbon dioxide in its place. This exchange occurs in the lungs through the alveoli and a web of minuscule blood vessels known as capillaries, which are positioned in the membranes of the alveoli. This allows oxygen and carbon dioxide to diffuse and pass freely from the respiratory system to the bloodstream.
Once it hits the arteries, oxygen molecules promptly bind to the RBCs that travel back to the heart. Simultaneously, the CO2 molecules in the lungs are eliminated from the body through the process of exhalation.
Aside from inhaling and exhaling, the pulmonary system also performs a multitude of tasks like:
