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.
Any kind of homeostatic imbalance in the body could trigger severe illnesses. An internal state of balance is maintained by a term called homeostasis. In order for the body to be balanced, it must maintain five functions. (1) atmospheric pressure (2) nutrients (3) oxygen (4) water (5) body temperature.
