The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain, it is known as involuntary muscle—it cannot be directly controlled by the conscious mind. Gross Anatomy of a Skeletal MuscleMost skeletal muscles are attached to two bones through tendons.
Muscles move by shortening their length, pulling on tendons, and moving bones closer to each other.

Lungs and Respiratory System of the Chest – Posterior (Back) View. [Continued from above] . . .
Atmospheric air enters the body through the mouth and nose and arrives in the chest through the trachea, or windpipe. The trachea is a large open tube lined with rings of cartilage. The cartilage of the trachea provides a flexible rigidity that maintains an open airway to and from the lungs at all times. At its inferior end the trachea branches into two bronchi that each enter one of the lungs.
Inside the lung each bronchi further branches into several smaller secondary bronchi, which in turn further branch into many smaller tertiary bronchi and finally branch into many tiny, flexible bronchioles. The inner lining of the bronchial tree is made of ciliated simple columnar epithelium with goblet cells. What Is Asthma?
