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.
Cell regulation is a broad term used to describe the many processes that occur within a cell that are aimed at maintaining homeostasis. Homeostasis is a balanced condition in which cell avoids harmful extremes of any form through various active or passive regulatory processes. Regulation processes moderate everything from the growth and replication rates of cells to the salt levels and acidity of the cellular environment.
