What are the parts of the lungs and their functions?
The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. The bronchioles eventually end in clusters of microscopic air sacs called alveoli.
What are the parts of the lungs?
Lungs. Bronchial tubes/bronchi. Bronchioles. Air sacs (alveoli)
How many parts of the lungs are there?
You have two lungs, the left lung and the right lung. The left lung is slightly smaller and has a notch to give room for the heart. Each lung is divided into lobes—the left lung has two and the right lung has three—which are similar to balloons filled with sponge-like tissue.
What are the 2 main functions of the lungs?
The lungs’ main role is to bring in air from the atmosphere and pass oxygen into the bloodstream. From there, it circulates to the rest of the body. The organs require help from surrounding structures in the body in order to breathe properly.
What are the 5 lobes of the lungs?
The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes. Only the right lung has a middle lobe.
Which lung is upper?
The right upper lobe of the lung is located in the right superior corner of the thoracic cavity lateral to the trachea and esophagus. It is superior to the horizontal and oblique fissures, which separates the upper lobe from the middle and lower lobes of the right lung.
What is lung function?
The most important function of the lungs is to take oxygen from the environment and transfer it to the bloodstream. The lungs are the major organs of the respiratory system , which helps provide the body with a continuous supply of oxygen.
What are lung bases?
Anatomically, the lung bases refer literally to the inferior concave surfaces of the lungs which directly contact the hemidiaphragms. However many radiologists, and other clinicians, use the term more generally to refer to the basal region of the lung, which like the lower zones, has no formal definition.
