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.
2. Use regulation of body temperature to illustrate maintenance of homeostasis by a feedback mechanism. 3. Use regulation of normal blood pressure to illustrate how the nervous system and the endocrine systems are both involved in maintaining homeostasis.4. Use the regulation of blood pH to illustrate that there are short-term and long-term mechanisms for maintaining homeostasis. 5.ody Systems and Homeostasis. The internal environment of the body is tissue fluid, which bathes all cells making up the body. The composition of tissue fluid must remain constant if cells are to remain alive and healthy. Tissue fluid is nourished and purified when molecules are exchanged across thin capillary walls.
