Study Notes
Respiratory System
- The respiratory system, composed of organs and other body parts, facilitates the exchange of gases: taking in oxygen and expelling carbon dioxide.
- This process ensures oxygen is delivered to the bloodstream for distribution throughout the body and removes carbon dioxide, a waste product of metabolism.
Nose
- The nose is the respiratory system's gateway, responsible for filtering, warming, and moistening inhaled air.
- It also houses the nasal cavities, essential for the sense of smell.
- Internal nares or choanae are the openings to the pharynx, while external nares are the external nostrils.
- Nasal conchae, or nasal turbinates, are folds in the mucous membrane that increase air turbulence, ensuring most air contacts the mucous membranes.
Pharynx
- The pharynx is a common passageway for both food and air.
- It connects the nasal and oral cavities to the trachea, allowing for breathing and swallowing.
- The pharynx is divided into three sections:
- Nasopharynx: Contains the pharyngeal tonsils (adenoids) that aid in immune defense.
- Oropharynx: The back portion of the mouth containing the palatine tonsils, also aiding in immune defense.
- Laryngopharynx: The bottom section of the pharynx where the respiratory tract splits into the esophagus and larynx.
Larynx
- The larynx, known as the voice box, is composed of vocal cords that vibrate to produce sounds as air passes through.
- The larynx is essential for talking, shouting, and other vocal sounds.
- It is a short, cylindrical airway leading to the trachea.
Trachea
- The trachea, or windpipe, is a tubular structure connecting the larynx to the bronchi.
- It facilitates the passage of air into and out of the lungs.
- The trachea is composed of several cartilaginous rings, providing flexibility.
Bronchi
- Bronchi are large tubes branching from the trachea, leading air to the right and left lungs.
- There are two types of bronchi:
- Right Main Bronchus: Serves the right lung.
- Left Main Bronchus: Serves the left lung.
- Bronchi deliver air from the trachea into the lungs for gas exchange.
Bronchioles
- Bronchioles are small, branching airways within the lungs.
- They connect the bronchi to alveoli, where gas exchange occurs.
- The primary function of bronchioles is to carry air deep into the lungs, facilitating gas exchange.
Alveoli
- Alveoli are tiny, sac-like structures in the lungs where the exchange of oxygen and carbon dioxide happens between air and blood.
- Each alveolus is one cell thick surrounded by blood vessels.
- Alveoli are responsible for exchanging oxygen and carbon dioxide with the blood.
Lungs
- The lungs are two cone-shaped organs within the chest, responsible for breathing by absorbing oxygen and expelling carbon dioxide.
- Each lung has a concave base resting on the muscular diaphragm.
- The left lung is divided into two lobes by an oblique fissure: Left Upper Lobe (LUL) and Left Lower Lobe (LLL).
- The right lung is divided into three lobes by oblique and horizontal fissures: Right Upper Lobe (RUL), Right Middle Lobe (RML), and Right Lower Lobe (RLL).
Diaphragm
- The diaphragm is a sheet of smooth muscle situated below the lungs.
- It plays a crucial role in breathing, contracting and relaxing to help draw air into the lungs and expel it.
Taking Care of Your Respiratory System
- Avoid smoking and exposure to secondhand smoke.
- Exercise regularly, aiming for at least 30 minutes of moderate exercise most days of the week.
- Maintain a healthy diet and stay hydrated.
- Get annual checkups with your healthcare provider.
- Stay current with vaccinations against respiratory infections, such as influenza, COVID-19, and RSV.
