Tubule example sentences

A comparison of the volume of the filtrate formed per day (180 litres per day) with that of the urine released ( 5 litres), suggest that nearly 99 per cent of the filtrate has to be reabsorbed by the renal tubules.JGA is a special sensitive region formed by cellular modifications in the distal convoluted tubule and the afferent arteriole at the location of their contact.Testis is composed of seminiferous tubules and stromal or interstitial tissue.At this stage the chromosomes align at the equator and the microtubules from opposite poles of the spindle get attached to the kinetochores (Figureure 4) of sister chromatids.Presence of such interstitial gradient helps in an easy passage of water from the collecting tubule thereby concentrating the filtrate (urine).ADH facilitates water reabsorption from latter parts of the tubule, thereby preventing diuresis.The tubule continues further to form a highly coiled network – proximal convoluted tubule (PCT).The efferent arteriole emerging from the glomerulus forms a fine capillary network around the renal tubule called the peritubular capillaries.Each nephron has two parts – the glomerulus and the renal tubule.Aldosterone causes reabsorption of Na+ and water from the distal parts of the tubule.Protonephridia, nephridia, malpighian tubules, green glands and the kidneys are the common excretory organs in animals.Malpighian tubules help in the removal of nitrogenous wastes and osmoregulation.The renal tubule starts with a double walled Bowman's capsule and is further differentiated into a proximal convoluted tubule (PCT), Henle's loop (HL) and distal convoluted tubule (DCT).Aldosterone acts mainly at the renal tubules and stimulates the reabsorption of Na+ and water and excretion of K+ and phosphate ions.DCT and collecting duct allow extensive reabsorption of water and certain electrolytes, which help in osmoregulation: H+, K+ and NH3 could be secreted into the filtrate by the tubules to maintain the ionic balance and pH of body fluids.
