Respiratory System: Organs, Facts, Anatomy & Function
What is the respiratory system? Your respiratory system is the organs and structures in your body that allow you to breathe. It includes your lungs, nose, mouth and the tubelike structures (airways) that connect them. You also have muscles and blood vessels that support your respiratory system, and ribs to protect it. These parts work together to bring oxygen into your body when you inhale and ...

The respiratory system is made up of organs and other parts of the body involved in breathing when you exchange oxygen and carbon dioxide.
Respiratory system - Wikipedia
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. In land animals, the respiratory surface is internalized as linings of the lungs. [1] Gas exchange in the lungs occurs in millions of small air sacs. In mammals and reptiles, these are called alveoli, and in ...

Other body systems that work with the respiratory system include the nervous system, lymphatic system , and immune system. The image shows an enlarged view of the airways and lungs, as well as the trachea; bronchial tubes, or bronchi; and bronchioles. The image also shows a close-up view of gas exchange at the alveoli.
Human Respiratory System - Functions, Diagram, Organs
The human respiratory system is vital for sustaining life, as it facilitates the exchange of gases—oxygen (O₂) and carbon dioxide (CO₂)—between the body and the external environment. The primary function of the respiratory system is cellular respiration, which provides chemical energy for the body’s metabolic functions. However, the system also serves several other important ...

Upper Respiratory Infection: Causes, Symptoms & Treatment
Symptoms and Causes What are the symptoms of an upper respiratory tract infection? Symptoms of upper respiratory infections depend on the cause and what part of your body is affected. Infections can lead to swelling in parts of your respiratory tract, causing conditions like pharyngitis, laryngitis and epiglottitis, which can have different ...
Respiratory tract - Wikipedia
The respiratory tract is the subdivision of the respiratory system involved with the process of conducting air to the alveoli for the purposes of gas exchange in mammals. [1] The respiratory tract is lined with respiratory epithelium as respiratory mucosa. [2] Air is breathed in through the nose to the nasal cavity, where a layer of nasal mucosa acts as a filter and traps pollutants and other ...
