Each organ on the left belongs to the digestive or excretory system. Match each organ to its correct function on the right.
1. Esophagus - moves food from the back of the mouth to the stomach
2. Stomach - uses muscle contractions and acid to physically digest food
3. Small intestine - breaks down food with chemical digestion, absorbs nutrients and passes them to the blood
4. Large intestine - absorbs water from digested food
5. Rectum - stores feces until it is expelled from the body
6. Liver - produces bile to help fats absorb into the bloodstream
7. Gall bladder - stores bile until it is needed by the body
8. Pancreas - produces a juice containing enzymes and bicarbonate and releases it into the small intestine
9. Kidneys - clean and filter impurities from the blood using tiny structures called nephrons
10. Urinary bladder - stores urine until it is expelled from the body
11. Skin - releases waste products and water when you sweat or perspire
12. Lungs - release carbon dioxide and water each time you exhale
Answer (2)
The question involves matching organs to their specific functions in the digestive and excretory systems. Here is a detailed breakdown of the organs and their corresponding functions:
Esophagus - The esophagus is a muscular tube that moves food from the back of the mouth to the stomach through a series of muscle contractions known as peristalsis.
Stomach - The stomach uses muscle contractions and gastric acid to physically and chemically digest food, turning it into a semi-liquid form called chyme.
Small intestine - The small intestine is responsible for breaking down food further through chemical digestion, absorbing nutrients into the bloodstream, and transferring waste products to the large intestine.
Large intestine - The large intestine absorbs water and salts from the remaining indigestible food matter, transforming it into feces.
Rectum - The rectum stores feces until it is expelled from the body through a process called defecation.
Liver - The liver produces bile, a substance that helps in the emulsification and absorption of fats into the bloodstream.
Gall bladder - The gall bladder stores bile produced by the liver until it is needed for digesting fatty foods in the small intestine.
Pancreas - The pancreas produces a digestive juice containing enzymes and bicarbonate, which it releases into the small intestine to aid in the digestion of carbohydrates, proteins, and fats.
Kidneys - The kidneys clean and filter impurities from the blood using tiny structures called nephrons, which help in the removal of waste products and excess substances, forming urine.
Urinary bladder - The urinary bladder stores urine until it is expelled from the body through the urethra during urination.
Skin - The skin releases waste products and water through sweat during perspiration, helping in temperature regulation and excretion.
Lungs - The lungs release carbon dioxide and water vapor each time you exhale, as part of respiration and the body's waste removal process.
Overall, this question tests your understanding of the digestive and excretory systems, recognizing the role of each organ within these vital processes.
Each organ mentioned plays a specific role in either the digestive or excretory system, from moving and digesting food to filtering blood and expelling waste. Understanding these functions helps clarify how our bodies process nutrients and eliminate waste. This knowledge is vital for recognizing the importance of these systems in maintaining overall health.
