Study Notes
Respiration Overview
- Respiration involves the exchange of gases crucial for cellular metabolism.
- Breathing consists of inhalation (drawing air in) and exhalation (pushing air out).
- During inhalation, the diaphragm contracts, expanding the chest cavity.
- During exhalation, the diaphragm relaxes, allowing the chest cavity to decrease in size.
- Aerobic respiration requires oxygen, while anaerobic respiration occurs in the absence of oxygen.
Unique Respiration Methods in Animals
- Some animals utilize plasma membranes for gas exchange.
- Skin can function as a respiratory surface in certain species.
- Insects often rely on a tracheal system for efficient transport of oxygen.
- Aquatic organisms use gills to extract oxygen from water.
- Lungs are the primary respiratory organs in many terrestrial animals.
Components of the Respiratory System
- Trachea: A flexible tube that conducts air from the throat to the lungs.
- Bronchi: Two major branches stemming from the trachea, leading directly into the lungs.
- Bronchioles: Smaller, hairlike tubes within the lungs that branch off from the bronchi and lead to alveoli.
- Alveoli: Tiny air sacs within the lungs where gas exchange occurs; they have a large surface area to optimize this process.
