Explanation:

  1. bladder- A hollow, muscular organ at the bottom of the abdomen that holds and discharges urine.
  2. chyme- Partly digested food that is passed from the stomach to the small intestine.
  3. digestion- The process by which food is converted into a form that can be used by cells.
  4. villi-Hair-like parts of the small intestine that absorb nutrients from food.
  5. esophagus- A muscular tube which transports food from the pharynx to the stomach
  6. urine- A liquid filtered from the blood by the kidneys and discharged by the body as waste.

Further Explanation:

During digestion, food is chemically and mechanically broken down into smaller particles. For instance, with lipids, this begins in the mouth, where food is mechanically crushed, and mixed with saliva to allow water based enzymes like lingual lipase to work- it's then transported to the stomach via the esophagus.  

Next in the stomach, a churning action mixes food with stomach secretions as chyme. The enzyme gastric lipase acts on lipids, breaking them up into their components. Then phospholipids, bile acids, bilirubin, and cholesterol are combined into bile in the liver, which when secreted into the duodenum of the small intestine; this comes from its storage site, the gall bladder, and functions as an emulsifier or as a detergent. These hold the fats and water together and increase the surface area of lipids, which can be further digested by enzymes so the nutrients are further broken down for absorption into the bloodstream.

After digestion, the process of absorption occurs within villi of the small intestine. Villi are small finger-like projections from epithelial cells of the small intestine; due to the projections, they have increased surface areas for absorption. Absorption involves several processes such as:

  •    endocytosis
  •    passive diffusion
  •    facilitated diffusion
  •    active transport
  •    secondary active transport (co transport)

Excretion, describes the removal of metabolic waste from the body, it typically involves the skin, lungs, kidneys, and liver. Urine, excess urea and water, is excreted from the bladder where it is stored before excretion through the urethra.
