* Nose: Takes in air, filters it, and warms it.
* Nasal passages: Lead to the pharynx.
* Pharynx: Connects the nasal passages to the trachea (windpipe).
* Trachea: Carries air to the lungs.
* Lungs: The primary organs of respiration, where oxygen is taken into the blood and carbon dioxide is released.
* Diaphragm: A muscle that helps the lungs expand and contract, allowing air to move in and out.
The process of breathing is similar to humans:
1. Inhalation: The diaphragm contracts and flattens, increasing the volume of the chest cavity. This creates a lower pressure in the lungs, drawing air in through the nose and trachea.
2. Exhalation: The diaphragm relaxes, returning to its dome shape. This decreases the volume of the chest cavity, forcing air out of the lungs.
Adaptations for breathing:
Wolves have some adaptations that help them breathe efficiently, especially while running long distances:
* Large lungs: They have larger lungs relative to their body size compared to humans.
* Efficient oxygen uptake: Their red blood cells have a high affinity for oxygen, allowing them to efficiently transport oxygen throughout the body.
* Strong respiratory muscles: Their powerful diaphragm and intercostal muscles help them draw in large volumes of air.
These adaptations allow wolves to breathe effectively during strenuous activities like hunting and running.
