When the pH of the extracellular fluid drops, indicating acidosis, the kidneys respond by increasing the excretion of hydrogen ions (H+) and reabsorbing bicarbonate (HCO3-) to help restore normal pH levels. They also produce new bicarbonate ions to further buffer the acidity. This renal compensation works alongside respiratory mechanisms to help regulate the body's acid-base balance.

What happens when the pH of the extracellular fluid declines?
When the pH of the extracellular fluid declines, it becomes more acidic. This can disrupt cellular functions, affect enzyme activity, and potentially lead to health issues such as acidosis. The body has buffers and regulatory mechanisms to help maintain the pH within a narrow range to ensure proper functioning.
Are the principal ions in extracellular fluid sodium and chloride and bicarbonate?
Yes, the principal ions in extracellular fluid are sodium, chloride, and bicarbonate. Sodium and chloride are the major cations and anions, respectively, while bicarbonate helps regulate pH balance in the body.
What is the main buffer in the extracellular fluid?
The main buffer in the extracellular fluid is the bicarbonate buffer system, which consists of bicarbonate ions and carbonic acid. This system helps to regulate the pH of the blood by maintaining a balance between H+ ions and bicarbonate ions.
What is the most abundant anion in extracellular fluid?
Extracellular fluid refers to all body fluid outside of cells. The most abundant anion in the extracellular fluid is chloride (Cl-).
Why pH for eye drops is 7.4?
The pH of 7.4 for eye drops is chosen because it matches the pH of tears, which are around 7.4. This helps to minimize irritation or discomfort when the drops come into contact with the eyes. Maintaining a pH similar to that of tears also helps to maintain the natural environment of the eye's surface.
What are the solutes that maintain balance between intracellular and extracellular fluid?
Electrolytes such as sodium, potassium, chloride, and bicarbonate help maintain balance between intracellular and extracellular fluid by regulating fluid and pH levels. These solutes play a crucial role in various physiological processes such as nerve conduction, muscle function, and maintaining proper cellular function.
Do neuroglia regulate extracellular fluid composition?
Yes, neuroglia help regulate extracellular fluid composition by assisting in the maintenance of ion concentrations, pH balance, and nutrient delivery in the brain and spinal cord. Astrocytes, a type of neuroglia, play a crucial role in this physiological regulation by creating a barrier between the blood vessels and the neurons.
What term describes the environment outside the cell?
The term that describes the environment outside the cell is the extracellular environment. It consists of the surroundings in which the cell exists, including factors like temperature, pH, and nutrients present in the surrounding fluid.
Does cell metabolism tend to lower or raise the pH of the ECF?
Cell metabolism tends to lower the pH of the extracellular fluid (ECF) by producing acidic byproducts such as carbon dioxide and lactic acid. The removal of these acids by the body's buffering systems helps maintain the pH within a normal range.
Where in the human body are buffers found?
Buffers are found throughout the human body, including in the blood, intracellular fluid, and extracellular fluid. These buffers help maintain a stable pH by absorbing or releasing hydrogen ions to prevent drastic changes in acidity or alkalinity. Examples of buffer systems in the body include bicarbonate in the blood and proteins in cells.
What is the pH of amniotic fluid?
Amniotic fluid has an alkaline pH (7.1 to 7.3)
