Homeostasis Biology 2: Form and Function. Overview Homeostasis = maintenance of constant internal environment Physiological controls –Negative feedback.
KIDNEY STONES. nephrolithiasis (kidney calculi or stones) is well- documented common occurrences in the general population nephrolithiasis (kidney calculi.
Homeostasis the steady-state physiological condition of the body Ability to regulate the internal environment important for proper functioning of cells.
ARTICULATIONS WHAT IS A JOINT? A site where two or more bones meet. Provides mobility Weakest point of skeleton.
Excretory: Disposal & Osmoregulation Excretion: Disposal of nitrogen-containing wastes Osmoregulation: Control of gain and loss of water and solutes Osmoregulation.
Water Balance & Excretion 9.4 & 9.5. Osmoregulation process of actively regulating the osmotic pressure of bodily fluids and cells hyperosmotic (hypertonic)
