1. What is reabsorption, when referring to the kidneys?
In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood. Substances are reabsorbed from the tubule into the peritubular capillaries.
2. What substances are reabsorbed in the kidney?
Sodium/proton exchanger, which enables reabsorption of bicarbonate. Glucose, amino acids and other substances diffuse out of the epithelial cell down their concentration gradients on passive transporters and are then reabsorbed by the blood capillaries.

Please be descriptive! thank you in advance!
1. Explain how solutes and water are reabsorbed in the kidney tubules. Be sure to include the reabsorption of Na+, glucose, water, Cl-, Ca++, K+ etc. Include in your discussion how the various solutes are reabsorbed (i.e. sodium, glucose, amino acids) and the concept of renal threshold and saturation. Discuss the process of filtration. In your discussion, describe the filtration membrane in the renal corpuscle and the pressures involved in filtration. Discuss how...

Creatinine is formed from creatine. It is excreted by the kidneys with little reabsorption. When a patient follows a meat restricted diet, the size of the patient’s somatic protein pool is directly proportional to the amount of creatinine excreted. Significant predictors of urinary creatinine concentration included age group, sex, race/ethnicity, body mass index, and fat-free mass. For instance, males excrete more creatinine than female. Additionally, the body does not distinguish between dietary creatine, which is converted to creatinine, from endogenously...
