response.
3. Describe the process of osmosis and its significance in cellular function.
Osmosis refers to the diffusion of gases in the bloodstream, affecting
respiration.
Osmosis is the passive movement of water across a semipermeable
membrane, crucial for maintaining cellular fluid balance.
Osmosis is the process of cell division that leads to tissue growth.
, Osmosis is the active transport of nutrients into cells, which is essential
for energy production.

6. Describe the potential effects of acidosis on the central nervous system
(CNS).
Acidosis can lead to CNS depression, resulting in symptoms such as
restlessness, confusion, and seizures.
Acidosis enhances CNS activity, causing increased alertness and
energy.

ions into the cells?
Decreased mitochondrial function
Increased membrane permeability
Dilation of the endoplasmic reticulum and other organelles
9. Which statement is true about potassium ions in acid base balance?
Acidosis causes potassium to move FROM cells into the
extracellular fluid (plasma) in exchange for hydrogen ions
Acidosis causes potassium to move INTO cells from the extracellular
fluid (plasma) in exchange for hydrogen ions
Alkalosis causes potassium to move INTO cells from the extracellular
fluid (plasma) in exchange for hydrogen ions
Alkalosis causes potassium to move FROM cells into the extracellular
fluid (plasma) in exchange for hydrogen ions
10. If a patient presents with fatty infiltration of the liver due to a high-fat diet,
what dietary changes would you recommend to prevent further liver
