Practice Other Topics from Excretory Products and Their Elimination

This topic describes the human excretory system. The human excretory system consists of a pair of kidneys, a pair of ureters, a urinary bladder and a urethra. It discusses the structures of the excretory system in detail.

This topic describes urine formation. The three main processes involved in urine formation, namely, glomerular filtration, reabsorption and secretion, are discussed here in detail.

The topic discusses the function of the tubules. The functions of the Proximal convoluted tubule, Henle’s loop, distal convoluted tubule and collecting duct are discussed.

This topic describes the mechanism of concentration of the filtrate. The process of the counter-current mechanism is discussed here. Human kidneys can produce urine nearly four times concentrated than the initial filtrate formed.

This topic describes the regulation of kidney function. The factors responsible for regulating the functioning of the kidneys are discussed in detail here.

This topic describes the process of micturition. It discusses the process involved in the release of urine from the body. An adult human excretes, on average, 1 to 1.5 litres of urine per day.

This topic discusses the role of other organs involved in the process of excretion. Other than the kidneys, lungs, liver, and skin also help eliminate excretory wastes.

This topic discusses some of the disorders of the excretory system. The process of haemodialysis, the role of artificial kidneys, and kidney transplantation are also discussed here.
