Hi!
There are two process that do these jobs, and they both occur at the cell membrane. Endocytosis is the take in of materials such as food into the cell. There are two types of endocytosis: Phagocytosis and Pinocytosis. Phagocytosis makes the cytoplasm of the cell extend and "surround" the food and packages it into a vacuole. Pinocytosis sets up "traps" along the cell membrane to tract and collect food. Exocytosis is the excretion of waste products out of the cell. Here is how Prentice Hall Biology described it "The membrane of the vacuole surrounding the material fuses with the cell membrane, forcing the contents out of the cell." This is like a counter part of endocytosis, the process by which cells take in materials from outside the cell.
Good Luck
The Exceretory System
The skin primarily eliminates waste products through sweat glands by releasing water, salts, and small amounts of urea. The respiratory system eliminates waste products, such as carbon dioxide, through exhalation. The urinary system filters waste products, such as urea, excess salts, and water, from the blood to form urine, which is then excreted from the body.
The body typically eliminates water through urination within 1 to 2 hours after drinking it.
The body typically processes and eliminates water through urine within 1 to 2 hours after drinking it.
Sponges eliminate carbon dioxide and cellular wastes through diffusion. As water flows through their pores, oxygen and nutrients are absorbed, while waste products are released into the surrounding water. Sponges do not have specialized organs for excretion, relying instead on passive diffusion.
The excretory system, including kidneys, eliminates waste.

The digestive system eliminates solid wastes through the large intestine and rectum. Waste material, in the form of feces, is stored in the rectum before being expelled through the anus during defecation.

Urinary - Rids body of nitrogen containing wastes & Conserves body water or eliminates excesses. Includes the Kidneys, bladder, & ureter

The kidneys are responsible for excreting water, excess fats, and various catabolic wastes from the body through the production of urine.
