The lungs are pyramid-shaped, paired organs that are connected to the trachea by the right and left bronchi; on the inferior surface, the lungs are bordered by the diaphragm. The diaphragm is the flat, dome-shaped muscle located at the base of the lungs and thoracic cavity.

How we reviewed this article: The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, aids the body in the exchange of gases between the air.
Human Lungs Anatomy
Respiratory system (Systema respiratorum) The respiratory system, also called the pulmonary system, consists of several organs that function as a whole to oxygenate the body through the process of respiration (breathing).This process involves inhaling air and conducting it to the lungs where gas exchange occurs, in which oxygen is extracted from the air, and carbon dioxide expelled from the body.

The Respiratory System (Structure and Function) (Nursing) Part 1
What do lungs do? Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung. For your lungs to perform their best, your airways need to be open when you inhale and when you exhale.

The lungs also get rid of carbon dioxide, a waste product of the cells. The lungs are a pair of cone-shaped organs made up of spongy, pinkish-gray tissue. They take up most of the space in the chest (thorax). The lungs are surrounded by a membrane (pleura). The lungs are separated from each other by the mediastinum, an area that contains the:

Each lung consists of: Apex - The blunt superior end of the lung. It projects upwards, above the level of the 1st rib and into the floor of the neck. Base - The inferior surface of the lung, which sits on the diaphragm. Lobes (two or three) - These are separated by fissures within the lung.

Lungs Diagram. Labeled Diagram of the Human Lungs Lungs are an excellent example of how several tissues can be compactly arranged, yet providing a large surface area for gaseous exchange. The current article provides a labeled diagram of the human lungs as well as a description of the parts and their functions.

Functionally, the lung is divided into a series of bronchopulmonary segments. The bronchopulmonary segments are the largest subdivision of a lobe. They are separated from adjacent segments by connective tissue septa and are also surgically resectable. They are 10 bronchopulmonary segments in the left lung and 8-10 in the left lung [9].

The Nasal Cavity. The nasal epithelium (Figure 20.6.1 20.6. 1 is lined with ciliated pseudostratified epithelial with goblet cells and this makes up the mucosal layer. Deep to this layer will be numerous bipolar cell nuclei. You will also find Bowman's (olfactory) glands that secrete mucus to help lubricate the mucosal layer and to dissolve.
