Study Notes
Respiratory System Anatomy
- Composed of 6 major parts: mouth, nose, lungs, larynx, trachea, and diaphragm.
- Stomach muscles assist with breathing.
- Airways, including those in the respiratory system, total 1,500 miles (NY to Dallas) in length.
- Sinuses regulate air temperature and humidity.
- Plants are crucial for breathing as they absorb CO2 and release O2.
Upper Respiratory System
- Mouth: Entry and exit point for oxygen.
- Nose: Primary entry point for oxygen.
- Sinuses: Hollow spaces that adjust air temperature and humidity.
- Pharynx: Moves air from the mouth/nose to the trachea.
- Larynx: Connects pharynx and trachea, involved in sound production.
- Epiglottis: Flap preventing food from entering the trachea.
- Trachea: Connects the pharynx to the lungs, supported by rings of cartilage.
Lower Respiratory System
- Bronchial Tubes: Filter air to ensure only clean air reaches the body.
- Mucus: Sticky substance in bronchial tubes that catches dirt and germs.
- Cilia: Hair-like structures in the bronchial tubes that remove germs.
- Lungs: Take in oxygen and expel carbon dioxide.
Respiratory Physiology
- Breathing occurs continuously and automatically.
- Gas exchange occurs between the body's cells and the external environment.
- Air primarily composed of Nitrogen (78%), Oxygen (21%), and Carbon Dioxide (0.04%).
- Inspiration: Diaphragm contracts, pulling air into the lungs, creating a flat shape.
- Expiration: Diaphragm relaxes, pushing air out of the lungs, returning to a dome shape.
Respiratory System Conclusion
- Air is warmed, moistened, and filtered before it reaches the alveoli.
- Alveoli are the primary site of gas exchange in the lungs, transferring oxygen from the lungs to the capillaries.
- Without oxygen, cells and the body cannot function properly, leading to death.
Common Respiratory Ailments
-
Asthma: Airway blockage due to swelling.
-
Respiratory Infections: Infections affecting the upper or lower respiratory system.
-
Chronic lung conditions such as Cancer and Cystic Fibrosis.
-
Triggers for asthma include: cold air, exercise, smoke, and allergens.
-
Upper respiratory infections: middle ear infections, tonsillitis, sinusitis, and the common cold.
-
Symptoms include: coughing, sneezing, congestion, fever, aches, and sore throat.
-
Lower respiratory infections: bronchitis, pneumonia, and tuberculosis.
-
Lung Cancer: Uncontrolled growth of abnormal cells in the lungs causing tumors.
-
Cystic Fibrosis: Genetic condition causing thick mucus buildup in the lungs leading to recurring infections.
