Question

What happens to useful substances which flow into nephridia along with the waste? Name the hormone which helps in the reabsorption of water in kedney. What is haemodialysis?

Answer 1

In case of humans, its not nephridia-its nephron. (i) Process of re-absorption occurs through Renal tubule. Substances like water,glucose, Na+, amino acids gets reabsorbed in the proximal tubule. The filterate then passes through loop of Henle where more reabsorption of water takes place. (ii) ADH (Anti-diuretic hormone) (iii) Hemodialysis:- when kidneys fail to function, large amount of wastes get accumulated in blood resulting in excess fluid and high blood pressure.In hemodialysis, only a few drops of blood are allowed to flow, through a special filter that removes wastes and extra fluid. The detoxified blood is then returned to the body.The special filter used in dialysis consists of a number of tubes with semi-permeable lining, suspended in a tank filled with the dialysis fluid. F

Answer 2

Answer:

Process of readsorption occurs through renal tubular. Substances like water, glucose, aminoacid gets readsorbedin the proximal tubular. The filtrate passes through loop of henleWhere more readsorption of water takes place the harmoneWhich helps in re adsorption of water in kidneys is ADH anti diuretic harmony.. Haemodilasis is a process in whichKidneys fails to function, large amount of wastes get accumulatedIn the blood resulting excess fluid and high blood pressure occurs. Only a few drop of blood are allowed to flow through a special filter thattemoves wastes and excess water. The detoxification blood is then returned into the body
