The xiphoid process functions as the site of attachment for several structures of the upper respiratory system, including the diaphragm, the rectus abdominis muscle and the transversus thoracis muscle. The cartilaginous projection may appear in several variations of shape depending on the genetics of the individual.Continue Reading
In some individuals, the process may be split into two segments. Alterations of this process do not have a negative consequence on the health of the individual. The xiphoid process attaches to three muscles that have several functions. The diaphragm is involved in respiration, and it separates the thoracic cavity from the abdominal cavity. The rectus abdominal muscle serves to support the spinal cord during activity that involves physical exertion. It supports other organs in the abdominal region and the intestines. It also functions to support normal respiration. The transversus thoracis muscle lines portions of the abdominal cavity.
Xiphoidalgia or xiphodynia is a rare disorder involving the process. It involves inflammation or tenderness of the process. Some symptoms of the disease include nausea and pain that radiate to the back, neck and shoulder. Symptoms may worsen after performing certain physical activities, such as bending or twisting. Relief may occur with the use of analgesics and other treatments.Learn more about Organs
According to About.com, the function of the rectus femoris muscle is to enable knee extension and hip flexion. The rectus femoris, along with five other hip flexors, is responsible for flexion that draws the legs towards the trunk of the body.Full Answer >
The primary function of the respiratory system is to provide oxygen to every part of the body through the process of inhaling oxygen and exhaling carbon dioxide. The respiratory system consists of tissues and organs inside the body that allow people to breathe. This system includes blood vessels, the lungs, airways and certain muscles. The major airways of the respiratory system include the nose, windpipe, mouth, bronchial tubes and larynx.Full Answer >
The respiratory system draws in fresh air from the environment, exchanges oxygen for waste gases in the lungs and expels the spent air back into the environment before taking another breath. The oxygen is then circulated through the body to fuel the metabolism of the cells.Full Answer >
Bronchioles are tiny airways that carry oxygen to alveoli, or air sacs, in the lungs and help stabilize breathing in the respiratory system, according to About.com. Bronchioles are lined with smooth muscular walls that constrict or expand to regulate airflow and prevent irritants from passing further along the respiratory tract.Full Answer >
