The respiratory system is the network of organs and tissues that help you breathe. Organ systems perform a specific task. This system affords protection of vital organs and permits locomotion of the organism; the bone marrow in the middle of long bones makes immune cells. The organs are of two types, namely tubular or hollow organs and compact or parenchymal organs. An organ system is a group of organs that work together as a biological system to perform one or more functions. Organs of the integumentary system include hair, nails, sebaceous glands, sudoriferous glands, and the largest organ of the body, the skin. Other aspects of its function include regulating electrolytes in body fluids and maintaining normal pH of the blood. An organ is a unique anatomic structure consisting of groups of tissues that work in concert to perform specific functions.
