Bird anatomy - Wikipedia
WebA bird’s wing produces lift and thrust during the downstroke. The air is deflected downwards and also to the rear. The bird reduces its angle of attack and partially folds its wings on the upward stroke so that it passes through the air with the least possible resistance. WebBirds have relatively small lungs that are rigid and not contractile like those of mammals, in which lungs expand and contract during the breathing cycle. Another critical difference is the absence of so-called air sacs in mammals. Such structures help birds to regulate air flow through their respiratory system. [10] Birds also lack the diaphragm. WebBirds have a system of air sacs in their ventilation system. The air sacs in dinosaurs work to produce a unidirectional flow where air enters and exits the lung at the same rate, … grassroots project management software free
