Homeostasis and the Body Systems

Since all tissues and organs contribute to maintain homeostasis, all organ systems are directly or indirectly playing a role. Nervous system Working as the body’s primary control center, this control the activities of almost every other organ in the body. Autonomous nervous system stimulates/inhibits secretions from the hypothalamus It controls contractions of skeletal and erector… Read More ›

Baroreceptor Mechanism

Arterial blood pressure is normally regulated within a narrow range, with a mean arterial pressure typically ranging from 85 to 100 mmHg in adults. It is important to tightly control this pressure to ensure adequate blood flow to organs throughout the body. This is accomplished by negative feedback systems incorporating pressure sensors (i.e., baroreceptors) that… Read More ›

Human Physiology and Homeostasis

Human physiology is the branch of biological science that explains the specific characteristics and mechanisms of our body that help it to function as a living organism. Homeostasis is the process by which the body maintains its internal environment at optimum conditions to function as a living being Homeostasis: maintenance of near-constant internal conditions in… Read More ›
