* Nitrogenous waste: Primarily in the form of urea, produced from the breakdown of proteins.
* Excess water: Monkeys drink water and get some from their food, but excess water needs to be excreted.
* Salts: These are regulated to maintain proper electrolyte balance.
Components of the Monkey Excretory System:
* Kidneys: The primary organs of the excretory system. They filter waste from the blood and produce urine.
* Ureters: Tubes that carry urine from the kidneys to the bladder.
* Bladder: A sac that stores urine until it is excreted.
* Urethra: The tube that carries urine from the bladder to the outside of the body.
Other Mechanisms of Excretion:
* Lungs: Monkeys exhale carbon dioxide, a waste product of respiration.
* Skin: Monkeys sweat, which helps to remove excess water and salts.
* Liver: The liver plays a role in breaking down toxins and waste products.
Interesting Note: Monkeys have a unique digestive system that allows them to extract nutrients from fruits and leaves, producing relatively little solid waste. This is why monkey droppings are often small and relatively dry.
