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.
The body's homeostatic control mechanisms, which maintain a constant internal environment, ensure that a balance between fluid gain and fluid loss is maintained. The hormones ADH (Anti-diuretic Hormone, also known as vasopressin) and Aldosterone play a major role in this.uman homeostasis (homeostasis is from Greek: á½Î¼Î¿Î¹Î¿Ï homoios, similar and ÏÏÎ¬ÏÎ¹Ï stasis, standing still) is the property of homeostasis within the human body. The human body manages a multitude of highly complex interactions to maintain balance or return systems to functioning within a normal range.
