Avian Anatomical System
Introduction
Anatomy is the science of the structure of an animal it is derived from the Greek word meaning “to cut up” according to Merriam-Webster. It is important to gain an understanding about the Avian Anatomical System because understanding it is essential when caring for a poultry flock or developing a successful cost-effective environment for them. Learning about the Avian Anatomical System includes fully understanding the external and internal anatomy of the bird. In doing so you will be able to effectively recognize when something is wrong and how to take the crucial steps to correct the problem. Furthermore, understanding the breakdown of the avian is crucial in recognizing a healthy avian verses sick or diseased …show more content…
Like humans the avian relies on their digestive systems to stay healthy as well as nourished. A bird can go without food for many hours because they have a digestive system that is more rapidly and proficient than many other vertebrate groups. The main sections of the avian digestive system are composed of the alimentary canal or digestive tract in addition to partner structures. We find that the ‘canal’ consist of the oral cavity, pharynx, esophagus and crop depending on the bird. Then there is the stomach, proventriculu, gizzards, both small and large intestine -Bird Digestion. The functions are vast The digestive system in birds include many organs that perform specific functions beginning with the first peck of food from the mouth or beak and ending with waste from the opening of the vent. For birds it is said the mouth is not that important in the digestive system. However, it is interesting that most birds have salivary glands, yet the beak and tongue helps birds maneuver nutriment that they swallow up. Chickens do not need teeth because they have a gizzard they use to grind up and break down food that is absorbed and used along the way. This helps to overcome the fact that they do not have teeth. According to information provided by the Digestive Physiology of Birds -Vivo, “Birds have a glandular stomach, or …show more content…
Reproductive System The male and female reproductive systems are different in the fact that rosters have two testes located internally in the body, Ductus Deferens that delivers the semen from the testes to the phallus and a Rudimentary phallus which is an internal protuberance. Females or hens normally have one left ovary as well as an Oviduct that produces the egg white and shell around the yolk. Their vent is also the opening from the digestive system but serves as the urinary tract and the reproductive tract.
Respiratory System for bird includes nine air sacs that are located in the neck area and body cavity that inflates the lungs and exchange air in and out.
Skeletal System “The skeletal system provides the strong framework for the support and protection of the remainder of the systems, organs and tissues that make up the body of the fowl. Bird bones that are homologous to bones found in other animals have evolved over time to enhance the ability of the bird to fly. While fowls are not able to fly well, they still retain that ability to some extent”, according to Poultry Cooperative Research Centre
