How many gram of potassium is there in 10 years old's body?? |
|
Answer» Answer: plz mark me as brainliest answer and follow me Guys ...... Explanation: Potassium is present in all body tissues and is REQUIRED for normal cell function because of its role in maintaining intracellular fluid volume and transmembrane electrochemical gradients [1,2]. Potassium has a strong relationship with sodium, the main regulator of extracellular fluid volume, including plasma volume. The total amount of potassium in the ADULT body is about 45 millimole (mmol)/kg body weight (about 140 G for a 175 pound adult; 1 mmol = 1 milliequivalent [mEq] or 39.1 mg potassium) [3]. Most potassium resides intracellularly, and a small amount is in extracellular fluid [2-4]. The intracellular concentration of potassium is about 30 times higher than the extracellular concentration, and this difference forms a transmembrane electrochemical GRADIENT that is maintained via the sodium-potassium (Na+/K+) ATPase transporter [4]. In addition to maintaining cellular tonicity, this gradient is required for proper nerve transmission, muscle contraction, and kidney function. Potassium is absorbed via PASSIVE diffusion, primarily in the small intestine [2,4,5]. About 90% of ingested potassium is absorbed and used to maintain its normal intracellular and extracellular concentrations [3,5]. Potassium is excreted primarily in the urine, some is excreted in the stool, and a very small amount is lost in sweat. The kidneys control potassium excretion in response to changes in dietary intakes, and potassium excretion increases rapidly in healthy people after potassium consumption, unless body stores are depleted [2,6]. The kidneys can adapt to variable potassium intakes in healthy individuals, but a minimum of 5 mmol (about 195 mg) potassium is excreted daily in urine [3]. This, combined with other obligatory losses, suggests that potassium balance cannot be achieved with intakes less than about 400–800 mg/day. |

Sclerenchymatous tissues are dead tissues. explain |
Answer» Sclerenchyma, in plants, support tissue composed of any of various kinds of hard woody cells. Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary WALLS containing lignin. The cells are rigid and nonstretchable and are usually found in nongrowing regions of PLANT bodies, such as the bark or mature STEMS. Sclerenchyma is one of the THREE types of ground, or fundamental, tissue in plants; the other two types are parenchyma (living thin-walled tissue) and collenchyma (living support tissue with irregular walls). Sclerenchyma cells occur in many different shapes and sizes, but two main types occur: fibres and sclereids.I hope this helps u out |
