Chicken Flight essays

Chicken Flight essays A chickens wing size in proportion to its body is very small compared to other birds. Supporting this idea is the evidence found in the lab measurements that were made last week: the chickens leg alone weighed approximately 215 g, where as a single wing weighed only 72 g. If the weight of a chicken is estimated and compared to the wing, then it is evident that a wing with so little muscle and mass could not support the massive weight of the chicken. Chickens also cant fly because of heart complications. The heart is essential to flight because it provides oxygen to the muscles that will be used. When one has a small heart in comparison with their body, movement must be minimized as to not strain the heart.. The proportion of heart size to body mass is naturally larger in birds (.8%) than in mammals (.6%) because of the endurance the heart needs to fly. Although similarities do exist, the chickens heart is much different than that of the Humans. Chickens have a very high metabolic rate where as humans have a medium one. A chickens heart can beat up to 300 beats per minute. The kind of muscle present in the wings of the chicken is also a major factor in their lack of ability to fly. White meat signifies the absence of major exercise, while dark meat shows constant exercise. In the domesticated chicken, which mostly sits and walks around, the dark meet is found in the leg and thigh area, whereas the white meat is in the wings (Lab). The absence of dark meat in the wing area is another indicator that chickens lack the necessities to fly because they are deficient in the muscles they need. ...
