Made up of the lungs and a series of passageways leading into and out of the lungs.
The lungs and related structures.
The series of organs and passages which take air into the lungs, and exchange oxygen for carbon dioxide.
The system of breathing apparatus including the nose, pharynx, larynx, tonsils, bronchi, and lungs.
The system that takes oxygen from the air and passes it on to the bloodstream, subject to a variety of lung and breathing disorders.
The group of organs that brings oxygen from the air into the bloodstream and expels the waste products, including carbon dioxide. The organs of the respiratory system accomplish the physical process of breathing to bring air into the body and then expel it, as well as the more complex biochemical process of respiration to fuel the cells of the body with oxygen.
The combination of organs and tissues associated with breathing. It includes the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and lungs and also the diaphragm and other muscles associated with breathing movements.
All the organs and tissues associated with the act of respiration or breathing. The term includes the nasal cavity and pharynx, along with the larynx, trachea, bronchi, bronchioles and lungs. The diaphragm and other muscles, such as those between the ribs, are also part of the respiratory system which is responsible for oxygenating the blood and removing carbon dioxide from it.
The organs involved in the interchange of gases between an organism and the atmosphere. In humans, this system consists of the air passageways and organs (nasal cavities, pharynx, larynx, trachea, and lungs, including bronchi, bronchioles, alveolar ducts, and alveoli) and the respiratory muscles.
Body system consisting of the lungs and air passages; enables respiration, supplying the body with oxygen and eliminating carbon dioxide as a waste product.
The organs that are involved in breathing. These include the nose, throat, larynx, trachea, bronchi and lungs.
The organs tasked with transporting oxygen from the air to the bloodstream and eliminating carbon dioxide.
The upper section of the respiratory system comprises dual nasal passages, the pharynx (throat), the larynx (voicebox), and the trachea (windpipe). The lower portion of the respiratory system encompasses two lungs enveloped by a double membrane called the pleura, along with the lower airways encompassing bronchi and smaller bronchioles. These structures are safeguarded by the ribcage. The airways culminate in numerous sac-like alveoli, where vital gas exchange occurs with the surrounding intricate network of blood vessels. These minute vessels link to larger pulmonary vessels for transportation to and from the heart.
The process of breathing involves the diaphragm, a domed muscle, and the muscles of the abdomen and chest, which encompass the intercostal muscles found between the ribs. The respiratory center situated in the brainstem governs respiration.
Certain respiratory system disorders can impact the air passages, leading to blockage of airflow either into or out of the lungs. On the other hand, there are disorders that influence lung tissues, leading to an inadequate exchange of oxygen and carbon dioxide. Additionally, specific conditions (like poliomyelitis) can hinder the chest muscles and diaphragm, impairing the expansion of the lungs and thereby affecting the functioning of the respiratory system.
