Anatomy: The Respiratory System

The purpose of the respiratory system is breathing, also called ventilation. The process of periodically moving air into and out of the lungs allows alveolar air that releases oxygen and absorbs carbon dioxide to exchange fresh air from the atmosphere. Ventilation is achieved from the system by alternating the direction of the pressure gradient of the air flow between the atmosphere and the alveoli by swelling and bouncing of the lungs. Contraction of the inspiratory muscle causes indirect expansion and contraction of the lung by continuously dilating and compressing the thoracic cavity after the lungs move.

In humans and other mammals, the typical respiratory system anatomy is the respiratory tract. The road is divided into upper airway and lower airway. The upper tract includes the throat above the nose, nasal cavity, paranasal sinus, throat, and throat. The lower section (Figure 2) contains the lower part of the larynx, trachea, bronchi, bronchioles and alveoli. The branch airway of the lower channel is usually called respiratory trachea or tracheobronchial tree (Figure 2). The interval between consecutive branch points along each branch of "tree" is often called branch "generation" and there are about 23 adults.

Why is the respiratory system? Indeed, every book on scuba diving, including Open Water's instruction manual, contains some information on respiratory anatomy and physiology. Why is this material important to explain scuba diving? First, it helps to explain the underlying cause of the main problems caused by stress - decompression and air embolism. Secondly, it helps to explain the processes that are important for each diving, so: breathe air under water. If you are already satisfied with the basic anatomy and physiology of the respiratory system, please proceed to Part D. If not, please read. (These materials are closely related to the rest of this book, so they are not listed in the appendix.) What is the function of the respiratory system? The function of the respiratory system is conceptually very simple: it draws oxygen from the atmosphere and removes carbon dioxide from the blood

Overview of respiratory system The main function of respiratory system is gas exchange. Air enters the inhalation (inhalation); passes through the respiratory pathway, exchanges oxygen (O 2) at the tissue level releasing carbon dioxide (CO 2); and removes carbon dioxide during expiration ). Acid-base balance is also a function of the respiratory system. The respiratory system consists of upper respiratory tract and lower respiratory tract and thorax. Upper respiratory tract - It consists of nose, mouth, throat, and throat - add moisture to the lungs with air. The lung is made up of 5 lungs. There are three on the right side and two on the left side. Cough reflex and mucous fimbrial clearance are mechanisms of protection of the upper respiratory tract
