The Henle's loops of these nephrons are thin and long and extend almost upto the tips of medullary papillae. The peritubular capillaries associated with these Henle's loops are also very thin and in the form of thin loops extending almost upto the tips of medullary papillae.

Patil Medical College PowerPoint Presentation: Definition Components Mechanism Factors Functions Other systems of counter current mechanism Applied aspects Definition : Definition A counter current system refers to a system in which the inflow runs parallel to, counter to, and in close proximity to the out flow for some distance. The counter current flow system is formed by U shaped tubules.

The normal kidney has tremendous capability to vary the relative proportions of solutes and water in the urine. The maximal concentrating ability of the kidney depends on how much urine volume must be excreted each day, to void the body of waste products of metabolism and ions that are ingested. A normal 70 kg human must excrete about mOsm of solute each day. When osmolarity of the body fluids increases above normal the posterior pituitary secretes more ADH. This increases the permeability of the distal tubule and collecting duct to water.

Understanding Heat Exchangers

Romina Ronquillo. Heat exchangers are devices designed to transfer heat between two or more fluids—i. Depending on the type of heat exchanger employed, the heat transferring process can be gas-to-gas , liquid-to-gas , or liquid-to-liquid and occur through a solid separator, which prevents mixing of the fluids, or direct fluid contact. Other design characteristics, including construction materials and components, heat transfer mechanisms, and flow configurations, also help to classify and categorize the types of heat exchangers available. Finding application across a wide range of industries, a diverse selection of these heat exchanging devices are designed and manufactured for use in both heating and cooling processes. This article focuses on heat exchangers, exploring the various designs and types available and explaining their respective functions and mechanisms. Additionally, this article outlines the selection considerations and common applications for each type of heat exchanging device.

Kidneys filter blood in a three-step process. First, the nephrons filter blood that runs through the capillary network in the glomerulus. Almost all solutes, except for proteins, are filtered out into the glomerulus by a process called glomerular filtration. Second, the filtrate is collected in the renal tubules. Most of the solutes get reabsorbed in the PCT by a process called tubular reabsorption.

This passive process is known as countercurrent exchange. The concentration of urine is controlled by antidiuretic hormone, which helps the kidneys to.

To dry food, a heat exchanger is needed so that the flue gas can be separated from the clean warm air to protect the food from contamination by the smoke, soot and ash. An analytical procedurewas developed to analyze the thermal and hydraulic performance of the DPHE with and without ribbing. Direct heating and Indirect heating on one base so comparisons can be made easily. In general, the heat exchangers used in regeneration may be classified as either regenerators or recuperators.

    The countercurrent term comes from the fact that the descending and ascending loops are next to each other and their fluid flows in opposite directions countercurrent.
