Loop example sentences

In some of the nephrons, the loop of Henle is very long and runs deep into the medulla.The proximity between the Henle's loop and vasa recta, as well as the counter current in them help in maintaining an increasing osmolarity towards the inner medullary interstitium, i.e., from 300 mOsmolL–1 in the cortex to about 1200 mOsmolL–1 in the inner medulla.In due course of time the meander loop cuts off from the river and forms a cut-off lake, also called an ox-bow lake.The flow of filtrate in the two limbs of Henle's loop is in opposite directions and thus forms a counter current.Due to continuous erosion and deposition along the sides of the meander, the ends of the meander loop come closer and closer.Similarly, small amounts of urea enter the thin segment of the ascending limb of Henle's loop which is transported back to the interstitium by the collecting tubule.A minute vessel of this network runs parallel to the Henle's loop forming a 'U' shaped vasa recta.A counter current mechanism operates between the two limbs of the loop of Henle and those of vasa recta (capillary parallel to Henle's loop).The descending limb of loop of Henle is permeable to water but almost impermeable to electrolytes.Though original GATT rules were applicable to trade in agriculture, these suffered from certain loopholes such as exemption to member countries to use some nontariff measures such as customs tariffs, import quotas and subsidies to protect interests of the farmers in the home country.The Malpighian corpuscle, PCT and DCT of the nephron are situated in the cortical region of the kidney whereas the loop of Henle dips into the medulla.A hairpin shaped Henle's loop is the next part of the tubule which has a descending and an ascending limb.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).The above described transport of substances facilitated by the special arrangement of Henle's loop and vasa recta is called the counter current mechanism (Figureure.The Henle's loop and vasa recta play a significant role in this.
