Respiratory System - Coggle Diagram
Respiratory System
Major functions of the respiratory system
receive oxygen
remove carbon dioxide
filter air
transport air into air sacs
upper respiratory structures and functions
Nose
The nose is the entrance and exit of airways and the hair removes all particles from air
nasal cavity
The nasal cavity is the space posterior to the nose and it is divided medially by naval septum
sinuses
The para nasal or sinuses open into the nasal cavity, is lined with mucous membrane, and reduces weight of skull
pharynx
The pharynx or the throat is the passageway for air and food and it produces sound or speech.
Lower respiratory structures and functions
Trachea
The trachea also known as the windpipe in a cylindrical tube in the thoracic cavity, it splits into the left and right primary bronchi and its inner wall is lined with ciliated mucus
Bronchial Tree
The bronchial tree is a branched mucous membrane lined tubular airway
Larynx
The larynx transports air in and out of the trachea, it keeps particles out of the trachea, it houses the vocal cords, and is the Adam's apple
Lungs
The lungs are soft, spongy, cone shaped organs that are separated medially by the mediastinum
Layers of Pleurae
The Parietal Pleurae is the outer layer
The Serous Pleurae lubricates the pleural cavity.
The pleurae is a double layered serous membrane
The Visceral Pleurae is the inner layer
Mechanisms of inspiration and expiration
The mechanisms of inspiring are the air moves from higher to lower pressure, the diaphragm contracts and moves down, enlarging the thoracic cavity
The mechanisms of expiration are the passive process of elastic recoil, the diaphragm and intercostal muscles relax, and the surface tension is increased in alveoli decreases volume
Volume and pressure relationships in thoracic cavity
