question 13

lymph capillaries called lacteals are located in the:
spleen.
liver.
thymus.
small intestine.

Explanation:

• Question 12: Plasma has a higher protein content compared to lymph and interstitial fluid. Proteins are large molecules that cannot easily pass through the capillary walls to enter the interstitial space (and thus lymph, which is formed from interstitial fluid). So, lymph and interstitial fluid have a lower percentage of proteins.
• Question 13: Lacteals are specialized lymph capillaries. They are located in the villi of the small intestine. Their main function is to absorb dietary fats. The spleen is involved in filtering blood and immune - related functions. The liver has functions like detoxification, protein synthesis, and metabolism of nutrients. The thymus is important for T - cell maturation.

Answer:

• Question 12: lower; proteins
• Question 13: small intestine.
