Kidneys are present in pair form, and they are bean-shaped in appearance. Kidneys in the body are present on both side they are present below the ribs and behind the abdomen. The primary function of kidneys is the filtration of blood. In kidney glomerulus and Bowman’s capsule are known as the main filtering unit that both are termed as renal corpuscle. A glomerulus is a sandwich between two arterioles that are responsible for the increase and decrease of blood pressure flow. The glomerulus is known as capillaries bed that capillaries are surrounded by podocytes which further leave finger-like projection between capillaries known as filtration slits. Slits are considered to be critical because they have to filter the blood.These slits filter blood depending on the size of particles like protein can not cross whereas salts, water and small sized particles have to be filtered (“Renal physiology: Glomerular filtration”, 2018).

When a person consumes a liter of distilled water rapidly, it will be absorbed into the blood due to which the colloidal osmotic pressure of blood will decrease.Water will diffuse out of the blood, and it will reduce the colloidal osmotic pressure in the interstitial and other extracellular body fluid as well. As a result, water will diffuse from interstitial fluid into the cells, and it will raise the intracellular fluid (“Fluid, Electrolyte, and Acid-Base Balance”, 2018).

In the Kidney and its Composition,the presence of fluid in the body is considered to be necessary because it is responsible for the lubrication, it helps in digestion, for the transport of oxygen and nutrients even it also protects the body.For the performance of body functions PH level of the body should be varied according to the body. Each body section has different mechanisms for the regulation or maintenance of PH. E.g. for water balance, electrolyte and as well as acid-base balance urinary system is present.In the human body, lacttic acid is the significant waste product of metabolism. Lactic acid is a strong acid on the other hand for the maintenance of body PH sodium bicarbonate and carbonic acid buffers are present in the blood (“pH of the Blood – 3 – Control mechanisms – M J Bookallil”, 2018).
