Pulmonary hypertension is a rare lung disorder in which the arteries that carry blood from the heart to the lungs become narrowed, making it difficult for blood to flow through the vessels. As a result, the blood pressure in these arteries -- called pulmonary arteries -- rises far above normal levels.
Homeostatic Control Mechanisms Homeostatic Control Mechanisms are devices for maintaining or restoring homeostasis. They involve virtually all of the bodyâs organs and systems.
Human body include mechanisms that help regulate the body, this includes organs, glands, tissues and cells. The adjusting of these enables the body to constantly be in a steady state. The main mechanisms of homeostasis are body temperature, body fluid composition, blood sugar, gas concentrations, and blood pressure. Blood Pressure. Pressure by which the blood is pumped around the body is controlled by a homeostatic mechanism. Body Temperature.
