The human body is a complex system of organs and tissues that work together to sustain life. The brain, heart, lungs, liver, kidneys, and other organs all play important roles in maintaining the body's functions. The brain controls thought, emotion, and movement through the nervous system. It also regulates various bodily functions such as hunger, thirst, and sleep. The heart pumps blood throughout the body, supplying oxygen and nutrients to tissues and organs. The lungs breathe in oxygen and expel carbon dioxide through respiration. The liver filters waste products from the blood and produces bile for digestion. The kidneys filter waste and excess fluids from the blood, producing urine that is excreted from the body. Other vital organs include the pancreas, which regulates blood sugar levels, and the skin, which protects the body from external damage.
