Respiratory System Day 1

Frontal Sinus (1) Nasal Cavity (3) Right Lung (13) Right Bronchus (14) Alveoli (17) Capillaries (18) Terminal Bronchiole (15) Diaphragm (25) Sphenoidal Sinus (2) Nasopharynx (4) Oropharynx (5) Laryngeal pharynx (6) Larynx and vocal Cords (8) Esophagus (9) Trachea (10) Mediastinum (12) Visceral Pleura (21) Parietal Pleura (20) Sternum (23) Epiglottis (7)

A, I: Sinuses Cavities that are filled with mucous. Moisten the air and surrounding tissue

B. Nasal Cavity Cilia: filters the incoming air Add to your diagram https://www.youtube.com/watch?v=CHAznLTcB14

T. Epiglottis Cartilaginous flap that prevents food from going into the lungs

J, K, L. Pharynx Contracts to move food to the esophagus https://www.youtube.com/watch?v=Ri8bBhw9msQ https://www.youtube.com/watch?v=pNcV6yAfq-g

N. Esophagus Muscular tube that automatically pushes food downward to the stomach

M. Larynx and Vocal Cords Vibrate and enable you to talk https://www.youtube.com/watch?v=Gv4evDGLgjQ

O.) Trachea Provides air to the lungs Contains cartilage to keep the pipe open Secretes mucous: provides moisture and kills bacteria https://www.youtube.com/watch?v=VQnfRc3ODgs https://www.youtube.com/watch?v=v9sJVicR9PY#t=104.615454

D. Bronchus Branch off of the trachea; take air to the lungs https://www.youtube.com/watch?v=v9sJVicR9PY#t=104.615454 https://www.youtube.com/watch?v=oGB5VaWmhuA

G. Terminal Bronchioles Branch off of the bronchus Contain alveoli for gas exchange http://blausen.com/en/video/how-lungs-function/

E. Alveoli: Gas exchange: Oxygen goes from the alveoli to the capillaries CO2 goes from the capillaries into the alveoli Alveoli Expanding: http://www.thevisualmd.com/read_videoguide/?idu=13388&q=%20alveolus Alveoli and Capillaries: https://www.youtube.com/watch?v=d-f3RL0KiUg

F.) Capillaries Warms air Gas Exchange

R. Parietal Pleura Fluid filled, lines the thoracic cavity (rib cage)

Q. Visceral Pleura Fluid filled, lines the lungs, decrease friction as lungs expand https://www.youtube.com/watch?v=Aw9OJLTlClQ&t=43s
