Respiration |
Major Organs: Nose, Nasal Cavity, and Para-nasal Sinuses |
|
|
Learn the Tale 22.1 of Resp. |
Continued... |
|
|
Respiratory Zone: Site of Gas Exchange |
Exchange of Gas takes place in the bronchioles, alveolar ducts, and alveoli, rest of the structures only conduct the air |
|
|
The Nose |
Moistens and warms the entering air Filters and cleans Air House the Olfactory Receptors |
|
|
Nasal Cavity |
Roof: ethmoid and sphenoid bones Floor: hard and soft palates Olfactory Mucosa: line all throughout the nasal cavity and rest of the structures Helps infections travel to ears, eyes, mouth, or lower respiratory region. |
|
|
Tonsils |
A lot of immune cells present that fight off infections, bacteria, viruses of the upper respiratory tract |
|
|
Paranasal Sinuses |
Lined by the same respiratory epithelium that lines the pharynx |
|
|
Voice Production |
Pitch is determined by the length and tension of the vocal cords
|
|
|
Larynx |
"Voice Box" Controls the air we inhale and exhale and adds vibrations to generate sound Valsalva's maneuver: closing some of the region of the upper resp tract (trumpet players) |
|
|
Epiglottis |
Controls the amount of air the we expire to generate voices and other daily noises such as laughing, sneezing etc |
|
|
Trachea |
Composed of three layers: Mucosa Submucosa Adventitia |
|
|
Bronchi |
Air can undergo almost 23 orders of branching that increase surface area to be able to conduct the exchange of gases Called the respiratory tree Divides into right and left bronchi Right Bronchi is wider, shorter, and more vertical than the left Bronchioles are less than 1mm in diameter Walls that make these bronchioles are very thin which help in gas exchange |
