Birds have very efficient cardiovascular systems that permit them to meet the metabolic demands of flight (and running, swimming, or diving). The cardiovascular system not only delivers oxygen to body cells (and removes metabolic wastes) but also plays an important role in maintaining a bird's body temperature.The avian circulatory system consists of a heart plus vessels that transport:
The heart is the driving force behind the avian circulatory system, and the vessels of the vascular system are the highways for oxygen, energy, and waste transport. Behind the feathers, a complex and fascinating collection of processes unfolds within these systems to support the diverse array of bird species at home on planet Earth.

Dogs with advanced degenerative mitral valve disease (ACVIM Stages C and D as well as advanced Stage B2) will be considered for open heart mitral valve surgery on a case-by-case basis after preoperative testing is evaluated by our team. Screening can be performed by your local cardiologist.
In general, the larger the species, the slower the rate of SA node discharge and the slower the heart rate. Birds can have a resting heart rate of ~115–130 beats/min, with active heart rates up to 670 beats/min, depending on size and species. Hummingbirds can have an active heart rate of >1,200 beats/min.
Heart Structure. Birds have a relatively large, four-chambered heart that pumps blood through the circulatory system. The heart is asymmetrical since each chamber of this muscular organ creates different pressure. Pumping blood to the lungs, for instance, requires less power than pumping to the rest of the body tissues. Chambers of the avian heart
