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 respiratory system helps maintain homeostasis by regulating the intake of air into the body and by removing carbon dioxide from the blood, which in turn assists the circulatory system's function and many other operations in the body. Homeostasis is the overall equilibrium of the body's internal organs and functions. Without these internal systems being properly balanced it can lead to a number of issues in the human body, including death, depending on the severity of the imbalance.Full Answer >
According to the Franklin Institute, the main purpose of the respiratory system is to supply oxygen to the blood, which delivers oxygen to all parts of the body. This is performed through respiration (i.e., breathing), which involves inhaling oxygen and exhaling carbon dioxide. Through an exchange of gases, the respiratory system acquires oxygen for the blood.Full Answer >
The upper half of the respiratory system consists of the nasal cavity, larynx and pharynx, while the lower half consists of the trachea, bronchi and lungs. The upper part of the system conducts gases, while the lower part is responsible for gas exchange.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 >
