Essay On Human Respiratory System

ACLS Guide to the Human Respiratory System

The human respiratory system consists of organs responsible for taking in oxygen and expelling carbon dioxide gas. Oxygen in air enters through the upper respiratory tract, which begins with the nose and the mouth, and is carried into the pharynx, the trachea, and into the lungs, where the exchange of gases occurs.

The Human Respiratory System

Human life depends on the presence of food, water and oxygen in order to sustain the body’s various functions. Every cell in the body needs oxygen to carry out its functions, including converting food to energy, reproduction, repairing damage, and more. The function of the respiratory system is to supply oxygen to the body. You may not know it, but you normally

It also helps to humidify and regulate the temperature of air passing from the environment and into the body.

In the nasal cavity, which lies behind the nose in the middle part of the face, the air is conditioned to pass through the pharynx. It is the part of the throat behind the mouth and nasal cavity, which forms part of the digestive and the respiratory system. It also plays an important role in vocalization.

At the base of the tongue is the epiglottis, an extension of a connective tissue that closes the voice box or larynx when swallowing food or water. The larynx conducts air to the lower respiratory tract and is involved in the production of sounds (voice).

Lower Respiratory Tract

The trachea, or windpipe, is a tubular organ that connects the larynx to the lungs. It is lined with special cells that produce mucus. From the trachea, air passes to the right and left lungs through their corresponding bronchi. Each bronchus divides into bronchioles, which are smaller tubes that carry air further down to the air sacs, also called
