Excessive loss of water from the extracellular fluid (ECF) leads to a rise in osmotic pressure in the ECF which causes cells to shrink as water leaves by osmosis.
True
False
The Correct Answer is A
True: When the ECF becomes hypertonic due to water loss (e.g., dehydration), water moves out of the cells into the ECF by osmosis, causing cellular shrinkage.

Correct Answer is E
Explanation
A. Tongue: The tongue assists in mechanical digestion and swallowing, making it an accessory organ.
B. Liver: The liver produces bile, aiding fat digestion, and is an accessory digestive organ.
C. Pancreas: The pancreas secretes digestive enzymes and bicarbonate, making it a key accessory organ.
D. Salivary glands: These produce saliva, initiating starch digestion-also accessory organs.
E. Spleen: The spleen is part of the lymphatic and immune system, not involved in digestion-not a digestive organ.
Correct Answer is C
Explanation
A. Because it saves one step in its synthesis: Zymogen secretion is about preventing premature activation, not simplifying synthesis.
B. So it will start digesting intracellular proteins of the chief cells more quickly: This would be harmful-zymogens prevent self-digestion of the cells that produce them.
C. So it acts only in the stomach lumen and does not digest intracellular proteins: Pepsin is secreted as inactive pepsinogen to prevent it from digesting the proteins inside chief cells. It is only activated to pepsin in the acidic environment of the stomach lumen.
D. So it can start digesting dietary proteins more quickly: Speed is not the reason for secreting it as a zymogen-safety is.
