Egestion vs. Excretion
Egestion is the passing out of undigested material from the body in the form of feces, through the anus while Excretion is a common term discussing the separation and throwing off toxic substances or waste materials from the body and tissues of a plant or animal. Egestion is the act of excreting useless or undigested material from a cell or the digestive tract in a unicellular or multicellular organism whereas Excretion is the elimination of waste products and toxic materials of excess substances and metabolism from organisms. Egestion occurs through mouth and anus, and excretion occurs from three major organs like the kidney, skin, and lungs. Excretion control osmotic pressure in the organism. Egestion is the final stage of feeding and contains undigested food, mostly cellulose in humans at the end of the alimentary canal is being passed out of the anus as feces whereas excretion is an important process for maintaining the digestive system in all living forms. Egestion is simply passing out undigested food from the end of the large intestine in the form of feces while wastes of excretion release in the form of urine and sweat. Egestion is carried out only in the animals on the contrary excretion is carried out both in plants and animals.
What is Egestion?
Egestion refers to the removal of the undigested material of food from the body. It is the final stage of feeding animals. Feces may contain complex food like fibers, pathogens as well as dead cells. Egestion may help to remove semi-solid feces by the digestive tract through the anus in animals. Sometimes before elimination Egestion is made in the large intestine and is stored in the rectum. Egestion occurs by exocytosis in protozoans. The egestion process is as follows: Indigestible materials are pushed to large intestine by peristalsis. Electrolytes and water have absorbed from the chyme. Undigested food material is fed by E-coli in the colon and produces vitamin B12, Vitamin K, B1, and B2. Chyme gets converted into semi-solid feces. Pellets of feces enter the rectum. Reflex action occurs through peristalsis in colon and rectum, pushing forces to move feces towards the anus. As the feces reach anus, involuntary relaxation cause defecation and voluntary action cause feces to expelled through the anus.
What is Excretion?
Excretion refers to the discharge of metabolic wastes from the body produced by plants and animals. Excretion is an essential process of all life forms. Skin, kidneys, and lungs are three major organs of excretion. Sweat glands produce sweat in the skin. Excretion material contains, urea, water, and salt. Excreting sweat helps retain the body cool in hot environments. When breathing, the lungs remove some water and excess carbon dioxide. Excretions occur through the kidneys remove excess water, salts, and urea to inhibit a contaminated build-up of these elements in the body. Wastes can consist of metabolic waste products and nitrogenous by-products such as, excess water, excess salts, carbon dioxide ammonia, urine, and sweat through which the organisms control osmotic pressure. Excretion also helps in promoting homeostasis. Plants excrete excess water by guttation and transpiration. The leaf drops in plants are also by excretion process. These are known as Excretophores. Saps and gums are the types of excretion in plants. Excretion is carried out both in plants and animals. The excretory system expels toxic wastes which otherwise accumulate in the body of human beings. Excretion helps through sweating in maintaining the body temperature of humans. Dogs have a limited number of sweat pores, and they use panting for the discharge of excess body temperature.
