Flashcards
Pulmonary ventilation
Pulmonary ventilation
The process of breathing in and out, involving expansion and contraction of the lungs to exchange gases.
External respiration
External respiration
The movement of oxygen ($O_2$) from the lungs into the bloodstream and carbon dioxide ($CO_2$) from the bloodstream into the lungs.
Internal respiration
Internal respiration
The movement of oxygen ($O_2$) from the bloodstream into the body cells and carbon dioxide ($CO_2$) from the body cells into the bloodstream.

Study Notes
Respiratory System Overview
- The respiratory system facilitates the intake of oxygen and removal of carbon dioxide, vital for metabolic processes.
- Oxygen is essential for chemical reactions producing energy, while carbon dioxide is a waste product.
- The respiratory system transports oxygen from the atmosphere to the body cells and carbon dioxide from cells to the atmosphere.
- Air quality, including temperature, moisture, pollutants, and particulates, varies and influences the respiratory process.
Respiratory System Organs
- Nose: Initial air passageway.
- Pharynx: Passage for air and food.
- Larynx: Voice box.
- Trachea: Windpipe, leading to the lungs.
- Bronchi: Two branches leading to each lung.
- Bronchioles: Smaller branching tubes within the lungs.
- Lungs: Major organs involved in gas exchange.
- Alveoli: Tiny air sacs in the lungs where gas exchange occurs.
- Diaphragm: Muscle enabling inhalation and exhalation.
- Pleura: Membrane surrounding the lungs.
- Intercostal muscles: Muscles between the ribs assisting breathing.
Respiratory Processes
- External respiration: Gas exchange between the lungs and the blood.
- Internal respiration: Gas exchange between blood and body cells.
Air Conditioning and Filtration
- Inhaled air is warmed or cooled to body temperature and moistened.
- Dust and particles are trapped by mucus lining the respiratory tract.
Cellular Respiration
- Cellular respiration requires oxygen and produces carbon dioxide.
