What should my body water percentage be for my age?
Water as percentage of body weight in adults
| Adults | Ages 12 to 18 | Ages 19 to 50 |
|---|---|---|
| Male | average: 59 range: 52%–66% | average: 59% range: 43%–73% |
| Female | average: 56% range: 49%–63% | average: 50% range: 41%–60% |
What is the greatest regulator of water intake?
The thirst center is in the hypothalamus of the brain. As the body loses water, the thirst center in the hypothalamus is stimulated, thus causing you to drink. The kidneys are the primary regulator of water output. Water regulation occurs mainly through the action of antidiuretic hormone (ADH) on the collecting duct.
Is urine output equal to water intake?
Water intake is obtained from fluid and food in the diet, and is mostly lost through urine output.
What is the most abundant cation in intracellular fluid?
potassium
What is the major cation found in intracellular fluid?
Potassium is the principal intracellular cation, with more than 98% of the body’s potassium found in the intracellular fluid. In the resting state, the cell membrane conductance for potassium is greater than sodium.
What is the most abundant cation found in the blood?
- Sodium. Sodium is the major cation of the extracellular fluid.
- Potassium. Potassium is the major intracellular cation.
- Chloride. Chloride is the predominant extracellular anion.
- Bicarbonate. Bicarbonate is the second most abundant anion in the blood.
- Calcium.
- Phosphate.
What is the most common intracellular anion?
Phosphate
What are the two major solutes in body fluids?
The dissolved substances in a solution are called solutes. In the human body, solutes vary in different parts of the body, but may include proteins—including those that transport lipids, carbohydrates, and, very importantly, electrolytes.
What anions are inside a cell?
Intracellular and extracellular fluid of neurons contain various kinds of charged ions. These include sodium (Na+), potassium (K+), and chloride (Cl-). Additionally, these fluids contain many negatively charged protein molecules called anions (A-).
Is calcium a cation or anion?
Positive and Negative Ions: Cations and Anions
| Family | Element |
|---|---|
| Potassium | Potassium cation |
| IIA | Beryllium |
| Magnesium | Magnesium cation |
| Calcium | Calcium cation |
What are some examples of cations?
Some examples of cations, or positive ions, include the following:
- Aluminum – Al. +3
- Barium – Ba. +2
- Bismuth – Bi. +3
- Cadmium – Cd. +2
- Calcium – Ca. +2
- Cesium – Cs. +
- Chromium (III) – Cr. +3
- Cobalt – Co. +2
What are the most common cations?
The most abundant cations present in water are calcium (Ca), magnesium (Mg), sodium (Na), and potassium (K); the most abundant anions are bicarbonate (HCO3), chloride (Cl), and sulfate (SO4).
Which one is a cation?
What is a cation? A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
Which cation is the smallest?
The smallest cation and the smallest anion are respectively
- A. H+ and H-
- B. H+ and F-
- C. Li+ and H-
- D. Li+ and F-
