The recommended daily amount of drinking water for humans varies. [1] It depends on activity, age, health, and environment.In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for females over 18; it assumes about 80% from drink and 20 ...
An ideal pH within the human body ranges from 7.35 to 7.45. [2] When the pH of the body falls below 7.35, an acidemia occurs. [2] Similarly, when the pH of the body rises above 7.45, an alkalemia occurs. [2]
Water intoxication can be prevented if a person's intake of water does not grossly exceed their losses. Healthy kidneys can excrete approximately 800 millilitres to one litre of fluid water (0.84–1.04 quarts) per hour. [15] However, stress (from prolonged physical exertion), as well as disease states, can greatly reduce this amount. [15]
Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). [1] The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism. [1]
In some cases, reabsorption is indirect. For example, bicarbonate (HCO 3 −) does not have a transporter, so its reabsorption involves a series of reactions in the tubule lumen and tubular epithelium. It begins with the active secretion of a hydrogen ion (H +) into the tubule fluid via a Na/H exchanger: In the lumen

A June 2022 study affirmed that the ability to balance is linked to a longer life, finding that those who failed to stand on one leg for a 10-second balance test were associated with an 84% ...
Assessing fluid status is key in differentiating between the two. In TACO, the patient will always have a positive fluid balance and will often present with hypertension, jugular venous distension, elevated BNP, peripheral edema, and will respond well to diuretics. In contrast, TRALI is not associated with fluid overload and the patient may ...
