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.
This adjusting of physiological systems within the body is called homeostaticregulation .Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector .The receptor receives information that something in the environment is changing.ome of the functions you will learn about inthis book are not specifically about homeostasis (e.g. how muscles contract), but in order for all bodily processesto function there must be a suitable internal environment. Homeostasis is, therefore, a fitting framework for theintroductory study of physiology.
