Waste Removal Cell vs. Human Organism

Human Waste Removal • • • • Excretory (Urinary) System Digestive System Respiratory System Integumentary System

Human Excretory (Urinary) System •

Kidneys - The human kidneys are the major organs of bodily excretion. The product of the kidneys is urine.

Kidney Function • • The kidneys filter the bloodstream in order to get all of the toxins out of your body, and also regulate certain body fluids.

Kidneys are vital organs that function to keep the blood clean and maintain chemical balance within.

Human Digestive System Also Gets Rid of Waste • • Liver - filters out harmful substances and turns them into bile.

Food travels to the esophagus, stomach and intestines. After most of the nutrients are removed from the food mixture there is waste left over — this excess exits the body through the anus in the form of stool.

Digestive System

Human Respiratory System • Rids the body of the cellular waste carbon dioxide.

Integumentary System (Skin) • Sweat rids the body of extra salts and some other impurities.

How Cells Get Rid of Waste • • • • Vacuole Lysosome Diffusion Also note that in cellular respiration, the mitochondria takes in Oxygen + Glucose and releases ATP (energy), Water (waste) and Carbon Dioxide (waste)

Cell Vacuole • Vacuole – membrane-bound sac that plays roles in intracellular digestion and the release of cellular waste products. In animal cells, vacuoles are generally small.

Cell Lysosome • Lysosome - they digest worn out or excess organelles, food particles and viruses or bacteria. They fuse with vacuoles and dispense their enzymes into those vacuoles, digesting their contents.

Cell Diffusion • Diffusion takes away the waste carbon dioxide produced by the cell. Diffusion is simply the movement of substances from an area of higher concentration to an area of lower concentration.
