Study Notes
Overview of the Respiratory System
- The Respiratory System delivers oxygen to the Cardiovascular System for transport to body cells.
- Oxygen is crucial for cellular activities, providing the energy needed for their functioning.
- The system also removes carbon dioxide, preventing harmful accumulation in tissues.
Essential Functions
- Uninterrupted functioning is critical; even a short interruption can cause irreparable damage and lead to death.
- Besides gas exchange, the Respiratory System helps maintain acid-base balance, essential for normal tissue function.
- It protects against pathogens and toxic substances inhaled during breathing.
- Smell-detecting cells assist with olfaction and play a role in speech production.
Process of Respiration
- Respiration involves two phases: inhalation and exhalation.
- Inhalation: air enters the lungs, oxygen travels to the heart, and is pumped into the bloodstream.
- Cellular respiration occurs as cells consume oxygen and produce carbon dioxide as a byproduct.
- Exhalation: carbon dioxide moves from cells to the bloodstream, returns to the heart, and is expelled through the lungs.
Structure of the Respiratory System
- Comprised of the upper respiratory tract (nose and pharynx) and lower respiratory tract (larynx, trachea, bronchi, and lungs).
- The trachea, or windpipe, branches into bronchi leading to the lungs.
- Bronchi further divide into smaller branches called bronchioles.
- The lungs are integral organs, coordinating with the circulatory system to oxygenate the body and eliminate carbon dioxide.
