Worked Solution & Example Answer:An investigation was carried out where the composition of mammalian blood was compared before and after it had passed through different organs - HSC - SSCE Biology - Question 10 - 2006 - Paper 1
Step 1
Which organ would produce this result?
Answer
To answer this question, consider the functions of each organ listed in the options:
-
Gall Bladder: Primarily responsible for storing bile. It doesn't significantly affect blood gas levels.
-
Kidney: Involved in filtering blood and may alter levels of electrolytes but it's not directly related to the changes regarding carbon dioxide or oxygen in a significant way.
-
Pancreas: Secretes digestive enzymes and hormones, but again does not have a major role in altering blood gas composition.
-
Small Intestine: This organ is involved in digestion and absorption of nutrients but also contributes to the gaseous exchange and can lead to increased CO2 due to digestion processes and cellular respiration.
Given the increase in carbon dioxide levels and digestion product levels, along with a decrease in oxygen levels, the organ that is most likely to produce this result is the Small Intestine (Option D).
