Here's a breakdown:

* Digestive Organs: These organs work together to break down food and absorb nutrients. They include the stomach, small intestine, large intestine, liver, gallbladder, and pancreas.

* Excretory Organs: These organs remove waste products from the body. The most important one is the kidneys, which filter waste from the blood and produce urine. The bladder stores urine before it is excreted.

While the abdomen houses the majority of these organs, some organs involved in excretion are located elsewhere:

* Lungs: These expel carbon dioxide, a waste product of respiration.

* Skin: This excretes sweat, which contains salts and other waste products.
