Structural Support Systems, Respiratory Systems, Excretory Systems in Various Animal Species

All different structures have the same exchange gas function. After oxygen has reached the cells of the blood or organism, some kind of circulatory system is needed to move nutrients and other substances throughout the body. Because of the size of the elephant, their organ structures need to be very large. Besides being different in size, the elephant's circulatory system resembles all mammals with a four-chamber heart and is effective for pumping blood through the blood vessels.

Eleven organ systems of the body are hulls, muscles, bones, nerves, circulation, lymph, respiratory, endocrine, urine / excretion, reproductive and digestive. Eleven organ systems have their own functions, but each organ system directly or indirectly depends on all other organ systems. In addition to having overlapping functions, the structures of various organ systems overlap. For example, the gonads of men and women belong to the reproductive and endocrine systems. Therefore, from an educational point of view, it is useful to divide the body into different organ systems. This minimizes the reality of these system interdependencies.

The respiratory system (also called breathing apparatus, ventilator) is a biological system consisting of specific organs and structures for exchanging gas of animals and plants. Anatomy and physiology to achieve this goal will vary greatly depending on the size of the living being, the living environment and the history of its evolution. In terrestrial animals, the respiratory surface is internalized in the inner layer of the lungs. Gas exchange in the lung occurs in millions of small air cells called alveoli in mammals and reptiles, but the atrium occurs in birds. These microscopic balloons have a very rich blood supply that keeps air in intimate contact with blood. These balloons communicate with the external environment via airway systems or hollow tubes, the largest of which is the trachea, which branches into two major bronchi in the middle of the chest. In birds, the bronchioles are called parabronki
