The Respiratory System

each of the two organs in the chest that helps one breathe

The lungs are essential organs responsible for exchanging oxygen and carbon dioxide with the bloodstream during respiration.

(anatomy) the hollow organ in the throat that contains the vocal cords and provides an air passage to the lungs

The larynx, commonly known as the voice box, is located at the top of the trachea and houses the vocal cords.

(anatomy) the membranous tube in the body that carries air from the throat to the bronchi

The trachea, also known as the windpipe, is a tube-like structure that connects the larynx to the bronchi, allowing air to pass in and out of the lungs.

the passage with ringed cartilages in the respiratory system that carries air from the throat to the lungs

(anatomy) the muscular body partition that separates the chest and abdomen

The diaphragm contracts and relaxes to control breathing.

(anatomy) the muscular body partition that separates the chest and abdomen

a flap-like structure that prevents food and liquids from entering the windpipe during swallowing

a small airway in the respiratory system that leads from the bronchi to the alveoli in the lungs

a major airway in the respiratory system that branches off from the trachea and leads to the lungsea

A tumor was discovered in her right bronchus during a routine check-up.

a thin membrane that lines the lungs and the inner surface of the chest cavity, providing a protective covering

the fluid-filled region between the visceral and parietal layers of the pleura that facilitates lung movement

a prominent, shield-shaped structure in the neck that protects the larynx and aids in sound production

a ring-shaped structure in the neck that supports the trachea and aids in the regulation of airflow during breathing

thin muscular bands in the larynx that vibrate to produce sound during speech and singing

elastic bands of tissue located within the larynx that vibrate to produce sound during speech and singing

the point in the trachea, or windpipe, where it divides into two smaller branches called the left and right main bronchi, which then lead to the respective lungs, facilitating the flow of air during breathing

small, air-filled sacs in the lungs where oxygen and carbon dioxide are exchanged between the air and bloodstream during respiration

a pair of mucous membrane folds in the larynx that help protect the airway and assist in sound modulation

a small airway in the lungs that connects respiratory bronchioles to alveolar sacs, facilitating the exchange of oxygen and carbon dioxide in the alveoli

a passage in the respiratory system that carries air from the trachea into the lungs
