Hints

Open one hint at a time and try again before the next.

Hint 1

Lymph is the fluid that escapes from capillaries into the spaces between cells. What is it called?

Hint 2

Think about what the lacteals in the villi absorb, and where the extra fluid around cells finally goes.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. Lymph is also called tissue fluid (extracellular fluid).

    1 mark

  2. Function 1: lymph carries digested and absorbed fats from the small intestine (through the lacteals).

    ½ mark

  3. Function 2: it drains excess fluid from the intercellular spaces back into the blood. (It also contains lymphocytes that help fight infection.)

    ½ mark

Answer: Tissue fluid; it carries absorbed fats from the intestine and returns excess tissue fluid to the blood (also fights infection).

Where the marks are

  • Gives the other name: tissue fluid / extracellular fluid (1 mark)
  • States any two functions: transport of fats, draining excess fluid to blood, fighting infection (½ + ½ marks)
