What is the respiratory organ?

The respiratory organ is an organ that is part of the respiratory system in the body. It cooperates with other respiratory organs to facilitate the gas exchange, which is the absorption of oxygen into the body and the expulsion of carbon dioxide. The upper respiratory organs such as the nose, the oral cavity and the pharynx are used to filter and moisten the air as it passes into the body. The lower respiratory system facilitates gas exchange with blood. They are responsible for a gas exchange where oxygen is transported to the blood, which is a process known as inspiration. After expiry, carbon dioxide is removed from the blood. The upper respiratory system is responsible for air filtering as it moves down to the lower respiratory system. And Well, the well -known respiratory organ, nose, contains a lobby with hair that filters large dust particles from the air. The following from the nose is the pharynx, which is also part of the digestive system.

working together in the lower respiratory system are lungs, broncHi, larynx, also known as voice box and trachea. The larynx containing vocal cords is made of cartilage and regulates air flow. Moving down from the larynx is the respiratory organ called the trachea, a tubular tract that is divided into two bronchi; They lead to the lungs.

The air is pushed through these airways, down to the lungs. Here the primary bronchi branch into smaller passages is called secondary bronchi and these divisions into even smaller tubes called bronchioles. The lungs are the respiratory organ placed in the pleural cavities. They contain alveoli that perform gas exchange with blood in the lung capillaries. The blood is oxygenated and carbon dioxide is removed and sent back towards the upper respiratory organs.

respiratory organs of different types also exist in other animals. In some small animals, the skin is the respiratory organ where the air is replaced by the body surface. Fish have gills to breathe in water and some scorpions and spiders use primitive lung forms called Lung book. Are made of punchingIt absorbs tissues with a large surface area that absorbs the maximum amount of oxygen. Some arthropods and invertebrate breath through the openings in their body, which transport air directly to the organs where it is absorbed.
