HOW DO KIDNEYS WORK?

Click here to view an animation on how a kidney works.

EXCRETORY SYSTEM

Click here for a great animation on how the kidney filters blood. Why is glucose returned to the blood but urea is removed from the blood? Can you explain what happens to water? How do the kidneys help maintain a balance in water levels in our bodies? When you sweat, do your kidneys produce a dilute urine or a concentrated urine? Why?

RESPIRATORY SYSTEM

SWALLOW animation

Click here to observe the process of swallowing and how the epiglottis prevents the food from going into the trachea.

PANCREAS

The human pancreas is an amazing organ with two main functions: [1] to produce pancreatic endocrine hormones (eg, insulin & glucagon), which help regulate many aspects of our metabolism and [2] to produce pancreatic digestive enzymes. Click here to read more.

DIABETES

Diabetes is a disease in which your blood glucose, or sugar, levels are too high. Glucose comes from the foods you eat. Insulin is a hormone that helps the glucose get into your cells to give them energy. Click here to access an interactive tutorial on diabetes. Click here to read more information about diabetes.

RESPIRATORY SYSTEM

Breathing moves air in and out of the respiratory system. During the respiratory process, gases are exchanged within the body. This animation illustrates how oxygen is carried to the blood as a result of inhalation and carbon dioxide is removed from the body during exhalation.
