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.The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this ...
WebMD explains how your lungs and respiratory system work by taking in air, removing oxygen and breathing out carbon dioxide.
The respiratory system provides oxygen to the body’s cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and ...
Go inside the human body and see first-hand how the respiratory system works. Vivid animation and real-life examples demonstrate the respiration process, including the transfer of oxygen into the ...
The Respiratory System: Pathway of OxygenThe respiratory tract conveys air from the mouth and nose to the lungs, where the gases oxygen and carbon dioxide are exchanged between the alveoli and the capillaries.Encyclopædia Britannica, Inc. The middle floor of the pharynx connects anteriorly to the ...
Your respiratory system’s primary function is to breathe in air, absorb oxygen into the bloodstream and breathe out carbon dioxide. We are all born with the same respiratory system organs that function the same way, but some of us end up, for a variety of reasons, needing a little help with our respiratory function.
Respiratory System Definition. The respiratory system consists of the set of organs involved in the uptake of oxygen from the atmosphere and the release of carbon dioxide generated during aerobic respiration.This gas exchange is also called breathing or external respiration.Organs specialized for breathing usually contain moist structures with large surface areas to allow the diffusion of gases.
Respiratory system, the system in living organisms that takes up oxygen and discharges carbon dioxide in order to satisfy energy requirements. In the living organism, energy is liberated, along with carbon dioxide, through the oxidation of molecules containing carbon. The term respiration denotes ...
The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, aids the body in the exchange of gases between the air and blood, and between the blood ...
