In this article we will discuss about:- 1. Meaning of Glomerular Filtration Rate 2. Advantages 3. Determinants 4. Forces Affecting 5. Estimation. Meaning of Glomerular Filtration Rate (GFR): Amount of filtrate formed by both kidneys together in unit time is called GFR. It is about 20% of the renal plasma flow. Normal value is 125 ml/min or 180 L/day. It [...]
The normal kidney has tremendous capability to vary the relative proportions of solutes and water in the urine. They can excrete urine with an osmolarity as low as 50 mOsm/L, when there is excess water in the body and ECF osmolarity low. They can also excrete urine with a concentration of 1200-1400 mOsm/L, when there is a deficit of water [...]
In this article we will discuss about:- 1. Definition of Acid-Base Homeostasis 2. Response to an Acid-Base Imbalance 3. Regulation. Definition of Acid-Base Homeostasis: Acid-base homeostasis is the part of human homeostasis concerning the proper balance between acids and bases, in other words, the pH. The body is very sensitive to its pH level, so strong mechanisms exist to maintain [...]
