| Define the villi | Tiny hair-like projections that line the inside of the small intestine. They contain blood vessels and help absorb nutrients. |
| Define the function of digestive enzymes | These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. |
| What is the waste product from the breakdown of proteins? | Ammonia |
| Define a nephron | A nephron is the structural and functional unit of the kidney. It regulates the concentration of water and minerals such as sodium by filtering the blood and reabsorbing the important nutrients. |
| What is the structure of a nephron? | Glomerulus, Bowman’s capsule, proximal and distal tubules, Loop of Henle, collecting tubule |
| Define the function of the Loop of Henle | To recover water and sodium chloride from urine. |
| Define selective reabsorption | The process where molecule are reabsorbed from the filtrate as they pass through the nephron. |
| Define the function of glomerulus | The glomerulus filters your blood |
| Define the function of the proximal tubules | Reabsorption of filtrate in accordance with the needs of homeostasis |
| Define the function of the distal tubules | Regulating extracellular fluid volume and electrolyte homeostasis. |
| Define the function of the collecting tubule | Transportation of urine and absorption of water |
