A low pressure reabsorptive system surrounding all portions of the tubules.This arrangement permits rapid movement of solutes and water between the fluid and the tubular lumen and the blood and capillaries .The peritubular capillaries rejoin to form the venas channels by which blood leaves the kidneys and empties into the inferior vena cava
Urine formation involves:the filtration of the blood by the glomerulus to form an ultrafiltrate of urine .The tubular reabsorption of electrolytes and nutrients needed to maintain the constancy of the internal environment and the secretion of waste materials . Filtration occurs as blood flows into the glomerulus from its afferent arteriole and plasma moves through the glomerular capillaries into Bowman's space. From Bowman's space the glomerular filtrate moves into the tubular segments of the nephron. Here through tubular reabsorption, electrolytes and nutrients move from the filtrate back into the blood stream Here also through tubular secretion substances move from the peritubular capillaries into the urine filtrate.
