PARAAORTIC BODY Meaning and
Definition
-
The paraaortic body, also known as aortic bodies or paraganglia, refers to a collection of small, bean-shaped glandular structures located in close proximity to the abdominal aorta. These bodies are part of the autonomic nervous system and play a crucial role in regulating oxygen and carbon dioxide concentrations in the blood.
The paraaortic bodies are composed of specialized cells called chief cells, which are highly vascularized. They receive blood supply from branches of the abdominal aorta and are intimately associated with sympathetic nerve fibers. These glands function as chemoreceptors, which means they respond to changes in the chemical composition of the blood.
Their primary function is to sense and regulate oxygen and carbon dioxide levels in the blood, thereby contributing to the body's overall homeostasis. When there is an increase in carbon dioxide concentration or a decrease in oxygen levels, the paraaortic bodies relay this information to the brain. In response, the brain triggers changes in breathing rate, heart rate, and blood vessel constriction, in order to restore the balance.
Additionally, the paraaortic bodies also release hormones called catecholamines, such as epinephrine and norepinephrine, into the bloodstream. These hormones further influence various physiological processes, including blood pressure regulation, metabolic rate, and stress response.
In summary, the paraaortic bodies are small glandular structures located near the abdominal aorta, responsible for monitoring and responding to changes in blood oxygen and carbon dioxide levels. They help regulate breathing rate, heart rate, blood pressure, and release hormones to maintain the body's equilibrium.

Etymology of PARAAORTIC BODY
The word "paraaortic body" is derived from combining two terms: "paraaortic" and "body".
"Paraaortic" refers to the location near or alongside the aorta, which is the largest artery in the human body. The term is constructed by combining the prefix "para-" meaning beside or alongside, and "aortic", which refers to the aorta.
"Body" in this context refers to an anatomical structure that is distinct or separate from surrounding tissues.
Therefore, the etymology of the term "paraaortic body" suggests an anatomical structure that is located adjacent to the aorta.
