Modes of Excretion
In this study material, we can learn about various modes of excretion among a wide range of organisms; the primary excretory wastes are Ammonia, Urea, Uric acid and Guanine.

Get answers to the most common queries related to the NEET UG Examination Preparation.
Ans:In humans, apart from the basic excretion process, various other wastes are produced and excreted in diverse methods. For example, kidneys create uric acid, lungs purify the blood by removing CO2, and finally, our skin loses waste through sweat.
Ans: These wastes are produced as residues of cellular metabolic activity in the form of ammonia, urea produced in the liver, and uric acid created by the conversion of ammonia in some creatures. Many animals have urine production as the primary method to expel nitrogenous wastes, while others create faeces.
Ans: No. Proteins do not accumulate in the body. Instead, they are metabolised to repair and build the body, resulting in the production of waste materials like ammonia and urea. These are then removed from the body through various modes of excretion.
Ans: Suppose the waste materials produced in metabolic processes are not removed from the body promptly. In that case, the waste materials will accumulate within the body and prevent the body’s functioning at the cellular level. Over an extended period, it can lead to organ failures or even complete system failures, endangering the life of the individual or living organism.
Ans: Plants also produce waste products during processes like photosynthesis in the form of oxygen and water vapour during the day and carbon dioxide at night. These gases are removed from the plant system through tiny pores on the leaves called stomata. Some other types of waste accumulate in the bark and flow out as resin.
