Erythropoiesis (from Greek 'erythro' meaning red and 'poiesis' meaning to make) is the process which produces red blood cells (erythrocytes).
Birds and mammals have the following characteristics in common: they are vertebrates, meaning they have an internal skeletonthey are warm-bloodedthey breathe using lungs, so â¦ have full respiratory systems they have circulatory systems. Most mammals give live birth, but there is a sub-group known as monotremes, which are the egg-laying mammals. 2  This group includes just the platypus and the echidna. 3  They are still mammals because, like all mammals, they feed their young on mothers' milk.
Answered by The Community. Making the world better, one answer at a time. Bird lungs have the same basic features as human lungs, such as a trachea, bronchi, lungs and capillaries etc, however birds' lungs operate in a cycling of air manner rather than a mixing action as in humans.ammals have blind-ending sacs (alveoli), whereas birds have air capillaries-which are loops between the parabronchi where gas exchange occurs. It should also be noted that unlike mammals, birds do not have a diaphragm-which means they can store air in their abdomen. 5 people found this useful.
