Homeostasis: positive/ negative feedback mechanisms
If you study biology or medicine, having a solid understanding of homeostasis is extremely important. All living systems are based on maintaining an internal environment and equilibrium. In homeostasis, positive and negative feedback mechanisms balance inputs, outputs, and responses. Most control mechanisms use a negative feedback loop, but some, like childbirth would be considered positive feedback.
The Cardiovascular System: Blood Vessels
Blood Vessels are often compared to a system of pipes with liquid circulating in them, but this analogy is only a starting point. Unlike pipes, blood vessels are extremely dynamic structures that constrict, relax, pulsate, and proliferate. In this article, we’ll examine the structure and function of these important circulatory pathways. If these pathways get […]
