Study Notes
- Lungs and the respiratory system are the main focus.
Factors Affecting Breathing
- Exercise can impact one's ability to breathe.
- Altitude is a factor that affects breathing.
- Weight/obesity is also a factor.
- Smoking affects breathing,
- Anxiety affects breathing.
- Drugs affect breathing.
Vital Capacity
- Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation.
Gaseous Exchange and Breathing
- Breathing involves body movements that allow air to enter and leave the lungs.
- Gaseous exchange (in alveoli) refers to the movement of gases across a respiratory surface.
- Respiration is the release of energy from the breakdown of food in cells.
Characteristics of Gaseous Exchange Surfaces
- Large and moist surface area is a characteristics, allowing substances to dissolve easier, making it ready for diffusion.
- Thin membranes are a characteristic.
- A short diffusion pathway is a characteristic.
- Copious/rich blood supply is a characteristic.
Aerobic Respiration
- Respiration involves chemical reactions that break down nutrient molecules in living cells to release energy.
- Aerobic respiration needs oxygen.
Anaerobic Respiration
- Anaerobic respiration releases of a relatively small amount of energy in cells by the breakdown of food substances.
- Aerobic respiration does not need oxygen.
Industrial and Domestic Applications of Anaerobic Respiration
- Anaerobic respiration can be found in the production of biogas, buttermilk, yogurt, and cheese.
- Anaerobic respiration is also found in wine-making, baking, and brewing industries.
