Main parts of the human respiratory system include the mouth, nasal cavity, lungs, bronchial tubes, diaphragm and trachea, according to National Heart, Lung, and Blood Institute. Other facets of the respiratory system are the larynx, epiglottis, alveoli and the blood vessels that carry oxygen away from the lungs.Know More
Air passes through the mouth, nasal cavity, larynx, trachea and bronchial tubes before reaching the lungs. The NHLBI explains the mouth and nose moisten the air before reaching further into the respiratory system. The epiglottis separates the trachea from the esophagus, and the flap of skin prevents food and drink from entering the lungs. The trachea, or windpipe, splits into two bronchial tubes that each go into a lung. Healthline explains the upper respiratory tract is located outside the chest cavity, and the lower respiratory tract are parts of the system lower than the larynx.
The diaphragm is a powerful muscle below the lungs that expands and collapses the organs when humans inhale and exhale. The NHLBI reveals the diaphragm is the main muscle used for breathing. Other breathing muscles line the ribs and collarbone. The respiratory system works by exchanging oxygen and carbon dioxide at the cellular level inside tiny alveoli. The aveloli are round air sacs at the end of tiny air tubes called bronchioles. Bronchioles are small airways that branch off from the bronchial tubes that go into each lung, according to the NHLBI.Learn more about Human Anatomy
The parts of the alimentary canal listed in order are the mouth, pharynx or throat, esophagus, stomach, small intestine and large intestine. The alimentary canal is the digestive system and includes the parts of the body with which food comes in contact from eating to waste elimination.Full Answer >
The respiratory system includes several types of tissue, including bronchi and bronchioles, as well as lung interior, pleural membrane and alveoli, according to InnerBody. The epiglottis is a thin piece of tissue covering the wind pipe, reports the National Heart, Lung, and Blood Institute.Full Answer >
The respiratory system is made up of the lungs, trachea, bronchi and diaphragm. These organs help people to breathe. Humans need to breathe to deliver oxygen to the body and rid the body of carbon dioxide, a waste gas that is produced by the body's cells.Full Answer >
The primary function of the respiratory system is to provide oxygen to every part of the body through the process of inhaling oxygen and exhaling carbon dioxide. The respiratory system consists of tissues and organs inside the body that allow people to breathe. This system includes blood vessels, the lungs, airways and certain muscles. The major airways of the respiratory system include the nose, windpipe, mouth, bronchial tubes and larynx.Full Answer >
