Pulmones

Los pulmones humanos son estructuras anatómicas de origen embrionario endodérmico, pertenecientes al aparato respiratorio, se ubican en la caja torácica, delimitando a ambos lados el mediastino. Sus dimensiones varían, el pulmón derecho es más grande que su homólogo izquierdo (debido al espacio ocupado por el corazón). Poseen tres caras; mediastínica, costal y diafragmática, lo irrigan las

arterias bronquiales, y las arterias pulmonares le llevan sangre para su oxigenación.

Lungs

Human lungs are anatomical structures of endodermal embryonic origin, belonging to the respiratory tract, are located in the chest, both sides delimiting the mediastinum. Its dimensions vary, the right lung is larger than its left counterpart (because the space occupied by the heart). They have three faces; mediastinal, and diaphragmatic rib, which supply the bronchial arteries and pulmonary arteries carry blood him for oxygenation.

LUNG

The lung is the essential respiratory organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function is to extract oxygen from the atmosphere and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, a process of gas exchange in the respiratory system.

The air that enters, or ventilates, the lungs enters the body through the mouth or nose, and travels through the pharynx, larynx, and trachea (windpipe).

Anatomía y características

Los pulmones están situados dentro del tórax, protegidos por las costillas y a ambos lados del corazón. Son huecos y están cubiertos por una doble membrana lubricada (serosa) llamada pleura. Están separados el uno del otro por el mediastino.

Anatomy and features

The lungs are located inside the chest, protected by the ribs and on both sides of the heart. They are hollow and are covered by a lubricated double membrane (serosa) called the pleura. They are separated from each other by the mediastinum.
