Anatomy and physiology of lung. The mediastinal surface faces the midline. Each lung is composed of smaller units called lobes. Anatomy of lungs airways.
The organs of the respiratory system include the nose pharynx larynx trachea bronchi and their smaller branches and the lungs which contain the alveoli. As they spread to the ends of the lungs they eventually form a grape like structure known as the alveoli. Gross anatomy of the lungs.
Anatomy and physiology of the respiratory system osmosis. Figure 2221 gross anatomy of the lungs. The larynx or voice box routes air and food into the proper channels.
On the inferior surface the lungs are bordered by the diaphragm. The nasal passages are particularly designed to act as an air conditioner. The diaphragm is the flat dome shaped muscle located at the base of the lungs and thoracic cavity.
Anatomy and physiology of the lungs bronchi gradually form more generations like a tree branch and become smaller and smaller. The diaphragm is the flat dome shaped muscle located at the base of the lungs and thoracic cavity. The apex of the lung is the superior region whereas the base is the opposite region near the diaphragm.

The costal surface of the lung borders the ribs. On the inferior surface the lungs are bordered by the diaphragm. Air is taken in via the upper airways the nasal cavity pharynx and larynx through the lower airways trachea primary bronchi and bronchial tree and.
The respiratory system refers to the series of organs responsible for gas exchange in the body. The lungs are pyramid shaped paired organs that are connected to the trachea by the right and left bronchi. Shown to the right.
The primary function of the upper airways is to prepare the inspired air for entry into the lungs. As a nurse it is important you know the basics about lung anatomy and the physiology of gas exchange because it will help you understand respiratory disorders. Gross anatomy of the lungs.
Anatomy physiology of the respiratory system the respiratory system is situated in the thorax and is responsible for gaseous exchange between the circulatory system and the outside world. The diaphragm is the large dome shaped muscle that contracts and relaxes during breathing. Fissures separate these lobes from each other.
The right lung is shorter and wider than the left lung and the left lung occupies a smaller volume than the right.
