Study Notes
Respiratory System Overview
- Mouth and nose serve as entry and exit points for air in the respiratory system.
- Alveoli sacs facilitate gas exchange between blood and atmosphere in the lungs.
- The trachea, or windpipe, divides into left and right primary bronchi.
Key Structures and Functions
- The diaphragm is a dome-shaped muscle crucial for breathing.
- Cilia are hair-like structures that keep air passages clean.
- The larynx produces sound as air passes through it and contains the thyroid cartilage, also known as the Adam's apple.
Anatomy of the Respiratory System
- Thoracic cavity houses the lungs, occupying most of the space.
- Bronchial tubes are the branches the trachea divides into.
- Each lung lobe: the left lung has two lobes and the right lung has three.
Respiratory and Circulatory Interactions
- The circulatory system transports oxygen and carbon dioxide between body cells and the respiratory system.
- Blood enters the lungs via the pulmonary artery.
- Alveoli are the smallest respiratory branches, allowing for gas exchange with surrounding capillaries.
Passageways and Air Flow
- The pharynx connects mouth and nasal cavities; it serves both respiratory and digestive functions, leading air to the larynx.
- External nares, or nostrils, open the nasal cavities to the environment.
- Nasal conchi are extensions that separate passageways in the nasal cavity.
Nasal Functions and Conditions
- Air is warmed, moistened, and filtered by the nose.
- Sinuses are openings in the skull that connect with nasal cavities.
- Allergic rhinitis refers to nasal allergic reactions.
Pharynx and Ear Connections
- The oropharynx is where the digestive and respiratory pathways intersect.
- Eustachian tubes connect the nasopharynx to the middle ear.
- Pharyngeal tonsils are lymphatic tissue located at the posterior wall of the nasopharynx.
Larynx Anatomy
- Thyroid cartilage, known as Adam's apple, is the largest cartilage in the larynx.
- Cricoid cartilage connects the trachea to the larynx, resembling a signet ring.
- The glottis refers to the opening of the larynx.
Vocalization and Sound
- Vocal chords vibrate due to exhaled air from the lungs, producing sound.
- Men typically have lower pitch voices due to longer vocal chords.
- Cartilage supports the trachea through a series of C-shaped structures.
