How do white tailed deer get oxygen?

White-tailed deer, like all mammals, get oxygen through breathing. Here's how it works:

* Inhalation: The deer takes in air through their nostrils, which leads to their nasal passages. The air is then filtered and warmed before traveling through the trachea (windpipe).

* Lungs: The trachea branches into two bronchi, which lead to the lungs. In the lungs, the air reaches tiny air sacs called alveoli.

* Gas Exchange: The alveoli are surrounded by tiny blood vessels called capillaries. Oxygen from the inhaled air diffuses across the thin walls of the alveoli and into the capillaries. At the same time, carbon dioxide (a waste product) diffuses from the blood into the alveoli to be exhaled.

* Exhalation: The deer expels the carbon dioxide-rich air through their nostrils.

This process of gas exchange in the lungs ensures that the deer's blood is constantly supplied with oxygen and that carbon dioxide is removed. This is essential for their survival.
