Solution
The correct option is D Liver
Mammals like humans and rabbits, many terrestrial amphibians and marine fishes mainly excrete urea and are called ureotelic animals. Urea forms when dietary proteins make amino acids after digestion. The liver breaks down excess amino acids to make ammonia, then converts this into urea, which is less toxic in the body than ammonia. Organisms that cannot easily and safely remove nitrogen as ammonia convert it to a less toxic substance, such as urea, via the urea cycle/ornithine cycle, which occurs mainly in the liver and released into the blood, which is filtered and excreted out by the kidneys.
Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.
The kidneys are a pair of bean-shaped organs on either side of spine, below the ribs and behind belly. The kidneys' job is to filter the blood.
The spleen is part of our lymphatic system, which fights infection and keeps body fluids in balance.
So, the correct answer is 'liver'.
