The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).
Chemical waste like excess water, minerals, and salt are filtered from the blood by the kidneys and secreted into the urine. Urine is transported from the kidneys to the bladder through ureters.
