The concentration of water in the blood is primarily controlled by the hormone vasopressin, also known as antidiuretic hormone (ADH). Produced by the hypothalamus and released by the posterior pituitary gland, ADH regulates water reabsorption in the kidneys, allowing the body to retain or excrete water as needed. Additionally, the kidneys play a crucial role in maintaining water balance through filtration and reabsorption processes. Together, these mechanisms help ensure proper hydration and osmotic balance in the bloodstream.
Nephrons basically assist the kidneys with some of its functions. Its main function is to regulate the concentration of water and sodium salts. It does this by filtering the blood.
If human blood is put in salt water, the water molecules in the human blood will lead to the lower concentration of water molecules. This process is called diffusion- water molecules going from high concentration to low concentration.
When a solution has the same concentration of water molecules and solutes as a red blood cell, it is considered an isotonic solution. In an isotonic solution, there is no net movement of water into or out of the red blood cell, maintaining its normal shape and function.
Distilled water would have a higher concentration of water molecules compared to red blood cells. Red blood cells have solutes dissolved in them, so they have a lower concentration of water molecules relative to distilled water. This concentration gradient would result in osmosis moving water into the red blood cells to equalize the concentrations.
The kidneys are the organs that directly regulate the concentration of water in the blood by filtering excess water and solutes from the blood to form urine. They also help maintain proper balance of electrolytes in the body by reabsorbing or excreting them as needed.
The greatest concentration of water in this scenario would be inside the red blood corpuscle. Sea water is a hypertonic solution compared to the inside of the cell, meaning it has a higher concentration of solutes. Water would flow out of the cell into the sea water in an attempt to equalize the concentration, causing the cell to shrink.
No. Rather, the CO2 concentration controls the pH. Other factors control concentration, such as temperature, pressure, contamination, and availability of CO2.
Nephrons have the same function in all kidneys. They allow the excretion of water, sodium and urea to form urine. They serve the function of removing waste chemicals such as metabolites and drugs from the body. Excretion of sodium and water is also important in the nephron as it allows the kidney to control blood pressure and blood volume.

Osmosis is the movement of water molecules from a region of high concentration to a region of low concentration through a selectively permeable membrane. If there is a high solute concentration outside the cell, water will leave body cells by osmosis - leading to plasmolysis (cell shrinking). If there is a high water concentration it will enter the cell by osmosis and the cell will burst.
Water is absorbed into the blood through the process of osmosis in the small intestines and kidneys. In the small intestines, water moves from an area of low solute concentration in the intestines to an area of high solute concentration in the blood. In the kidneys, water is reabsorbed from the filtrate back into the blood to maintain proper hydration levels in the body.
