Levels of Organization and Homeostasis Quiz

Homeostasis refers to the maintenance of a stable internal environment within the body. Examples of homeostatic mechanisms include receptors detecting changes in body temperature, set points for maintaining blood sugar levels, and effectors like sweat glands regulating body temperature.

The factors homeostatically regulated in the body include the concentration of nutrients, O2 & CO2, waste products, pH, water, salt, electrolytes, volume, pressure, and temperature.

The circulatory system transports O2, CO2, nutrients, waste, electrolytes, and hormones. The digestive system breaks down nutrients for absorption and supplies water & electrolytes. The respiratory system facilitates gaseous exchange. The urinary system removes excess salts, water, acid, and waste products. The skeletal system provides support and supplies Ca2+. The muscular system enables locomotion. The nervous system coordinates most activities.
