Carbon dioxide dissolves in water easily to form an acidic solution which can lower the ph of cells. this can reduce the activity of enzymes in the body which are essential for controlling the rate of metabolic reactions. a common mistake is to think that faeces (poo) is excreted by the body.
3 Excretion Notes Pdf Kidney Urinary System Through excretion, urea is removed which prevents it from reaching toxic levels in the body. What is excretion? excretion, which is the removal of waste products formed by metabolism, ensures that these waste products (like co2 and nitrogenous wastes) do not build up to toxic levels. Chapter 7 e»cretion and egestion excretion: remove of excretory products: urea, removed excretory organs: kidney, egestion: removal of of metabolism; egested material is called excretion in humans urea: made in the name products made during water and carbon dioxide; can cause damage to cells if not and skin; form part of the excretory system. The excretory system overview: the kidneys are one of the three organs of excretion (lungs skin). the kidneys remove ammonia, urea, and uric acid, and maintain water balance.

Excretion is defined as the process by which organisms get rid of waste products during its metabolism. it is the removal of waste products of metabolism which are harmful or would in time interfere with normal functions of organisms. Waste products of protein metabolism are excreted, water and electrolyte levels are controlled and ph (acid–base balance) is maintained by excretion of hydrogen ions. In human and other complex animals, the organs of excretion are the lungs, kidneys, liver, and skin. these organs work with the circulatory, nervous, and endocrine system to keep the body’s internal environment constant. on other words, these organ systems maintain homeostasis. Urine is the waste product which contains excess water, salts and spent hormones and drugs. water, salts and urea are the excretory products of skin in the form of sweat. kidneys excrete urea and excess water and salts urea is formed in the liver from excess amino acids.
