Circulatory System
There are three important organs of the deer's circulatory system that deserve particular attention--the heart, lungs, and spleen.
Heart. Whitetail Deer, like most mammals, have a four chamber heart which circulates blood through the circulatory system. It transfers oxygen and nutrients throughout the body and carries away carbon monoxide and waste materials for disposal.
Lungs. The Whitetail's Lungs perform the same function as in all mammals, transferring oxygen into and carbon monoxide out of the blood circulated through the aveoli.
Spleen. The spleen is an important producer of blood cells--primarily Lymphocytes. Erythrocytes can be stored in large amounts. The spleen of deer belongs to the blood-storing type, which is characteristic of endurance runners. Therefore, spleens of animals that die minutes after being wounded will be of much lower weight than spleens of animals that die instantly.
