Study Notes
Key Components of the Respiratory System
- Diaphragm: The primary muscle responsible for inhalation and exhalation.
- Hemoglobin: A protein in red blood cells that transports oxygen throughout the body.
- Epiglottis: A flap that prevents food from entering the windpipe during swallowing.
Respiratory Functions
- Cilia: Tiny hair-like structures that help move mucus out of the lungs and throat.
- Heat Addition: Blood warms the air as it passes through the nasal cavity.
- Mucus Production: Sinuses generate mucus that moisturizes inhaled air.
Anatomical Structures
- Larynx: Known as the voice box, it vibrates to produce sound.
- Nose: The preferred entry point for air, equipped with filters to trap particles.
- Septum: The wall that divides the nasal cavity, increasing surface area for air processing.
- Alveoli: Tiny air sacs in the lungs where gas exchange occurs.
Processes of Respiration
- Internal Respiration: Refers to gas exchange between blood and body cells.
- External Respiration: Essentially synonymous with the act of breathing.
- Pulmonary Artery: Carries deoxygenated blood from the heart to the lungs.
Breathing Mechanics
- Diaphragm Movement: Must move downward to create a vacuum for inhaling air.
- Carbon Dioxide Management: Increased levels trigger faster breathing, especially after exercise.
Breathing Control
- Medulla Oblongata: Brain region that regulates the rate of breathing.
- Response to CO2 Levels: The brain monitors carbon dioxide concentration to adjust breathing accordingly.
Additional Insights
- Lung Structure: The right lung consists of three lobes, while the left lung has two.
- Lymphatic Function: Lymph helps combat infections and is part of the immune system.
- Tongue's Role: It controls the epiglottis, ensuring the proper passage of air and food.
Interconnectedness of Systems
- Pharynx: Connects the mouth, nose, and ears for coordination of breathing and swallowing.
- Ear Connection: The ear is connected to the pharynx, indicating an integrated structure among senses and respiration.
Physiological Responses
- Recovery Rate: A measure of fitness, indicating how quickly normal breathing returns after exertion.
- Breathing and Swallowing: Cannot occur simultaneously due to the epiglottis blocking the air passage when swallowing.
