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 ...
The lungs are not capable of expanding to breathe on their own, and will only do so when there is an increase in the volume of the thoracic cavity. [73] This is achieved by the muscles of respiration, through the contraction of the diaphragm, and the intercostal muscles which pull the rib cage upwards as shown in the diagram. [74]
Lung volumes and lung capacities refer to the volume of air in the lungs at different phases of the respiratory cycle. The average total lung capacity of an adult human male is about 6 litres of air. [1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath.
t. e. Respiratory epithelium, or airway epithelium, [1] is a type of ciliated columnar epithelium found lining most of the respiratory tract as respiratory mucosa, [2] where it serves to moisten and protect the airways. It is not present in the vocal cords of the larynx, or the oropharynx and laryngopharynx, where instead the epithelium is ...
Description. Respiratory system complete en.svg. English: the respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body. Image renamed from Respiratory system complete.svg. Français : Le système respiratoire est composé des voies respiratoires, des poumons, et ...
Pulmonary circulation. The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs. In the lungs the blood is oxygenated and returned to the left atrium to ...
Pulmonary function testing is a diagnostic and management tool used for a variety of reasons, such as: Diagnose lung disease. Monitor the effect of chronic diseases like asthma, chronic obstructive lung disease, or cystic fibrosis. Detect early changes in lung function. Identify narrowing in the airways.
