Study Notes
Respiratory System Functions
- The primary function of the respiratory system is to bring oxygen into the body and remove carbon dioxide.
Breathing Process
- The diaphragm is responsible for the act of breathing, playing a crucial role in the process of inhalation and exhalation.
Ventilation
- Adequate ventilation depends on the coordination of the diaphragm and intercostal muscles.
Gas Exchange
- The alveoli, tiny air sacs in the lungs, are involved in gas exchange with the blood, exchanging oxygen and carbon dioxide.
Respiratory System Components
- The upper respiratory system includes the nose, mouth, and throat, and its main function is to warm, humidify, and filter the air we breathe.
- The lower respiratory system consists of the trachea, bronchi, bronchioles, and lungs.
- The pleural membrane, a thin layer of tissue, plays a crucial role in the respiratory system, facilitating the expansion and contraction of the lungs during breathing.
Respiratory Process
- The first process of the respiratory system is inhalation, which involves the contraction of the diaphragm and the expansion of the lungs.
- The bronchioles, small airways in the lungs, are responsible for directing air to the alveoli, where gas exchange occurs.
Lungs and Gas Exchange
- The alveoli, where gas exchange occurs, are responsible for exchanging oxygen and carbon dioxide in the lungs.
- The pulmonary capillary, a network of tiny blood vessels surrounding the alveoli, plays a crucial role in gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
Respiratory System Protection
- The upper respiratory system, particularly the nose and mouth, are responsible for protecting the body from foreign matter, such as dust, bacteria, and other pathogens.
