Liquid eg: by skin (sweating) basic unit of kidney: nephron (specialised cells) millions of nephron present in one kidney deoxygenated blood kidney to heart 2 ureters, sends wastes to urinary blood renal vein heart waste product: ammonia kidney kidney converts ammonia to urea right kidney is slightly down than left kidney.

Excretion Notes Pdf Biology Physiology In this chapter, you will learn the mechanisms of elimination of these substances with special emphasis on common nitrogenous wastes. ammonia, urea and uric acid are the major forms of nitrogenous wastes excreted by the animals. Excretion excretion is the removal of the metabolic wastes of an organism. wastes that are removed include carbon dioxide, water, salt, urea and uric acid. all excreted wastes travel at some time in the blood. humans produce waste products that must be removed from their body. •the circulatory system carries oxygen, nutrients, and hormones to tissues of the body and removes waste product (like carbon dioxide) away from tissues of the body. Counter current flow of filtrate in two limbs of henle's loop and two limbs of vasa recta maintain a concentration gradient in the medullary interstitium interstitial fluid and dilutes the filtrate as it moves up.

Several organs take part in human excretion. the lungs, skin, liver, and the transport system play important roles; however, the main excretory organs are the kidneys. Excretion from the lungs gaseous or volatile substances can pass from the blood circulation into the alveoli by passing across the endothelium and epithelium of the alveolar membrane. The excretory organs maintain constant internal environment required by the body cells by conserving certain substances and eliminating wastes like urea, uric acid, sweat, carbon dioxide and bile pigments. Egestion should not be confused with excretion because most of the contents of the faeces, apart from the bile pigments, have not taken part in reactions in the cells of the body.
