Answer 2

Anatomy of Fish Excretory Organs

Fish have specialized organs for excretion, including the kidneys and the gills. These organs play a crucial role in maintaining the osmotic balance and removing waste products from the fish's body.

Kidneys

Fish kidneys are responsible for filtering waste products from the blood and regulating the water and ion balance in the body. The kidneys of fish are relatively simple compared to those of mammals. They consist of numerous nephrons, which are the functional units responsible for filtration and reabsorption. The nephrons filter waste products, such as ammonia, urea, and uric acid, from the blood and excrete them as urine.

Gills

Gills in fish serve a dual purpose: respiration and excretion. While fish primarily use gills for extracting oxygen from water, they also eliminate certain waste products through the gills. Ammonia, a byproduct of protein metabolism, is excreted across the gill membranes into the surrounding water. This process is known as ammonia excretion.

Osmoregulation

Fish live in a watery environment, and maintaining the right balance of water and ions in their bodies is crucial for their survival. Fish have adapted various mechanisms to regulate osmotic balance. Some fish, like marine teleosts, drink seawater and excrete excess salt through specialized cells in their gills. Freshwater fish, on the other hand, excrete large amounts of dilute urine to get rid of excess water and retain essential ions.
