The diagram shows a model of a nephron and its associated blood vessels.
This model has been criticised for being a poor representation of a nephron. Which of the following statements explain(s) this?
1. The rubber tubing at B is not split up into numerous branches like the capillary network of the glomerulus.
2. The rubber tubing at B should be continuous and not contain small pores.
3. The stem of the thistle funnel (E) is not coiled to represent the convoluted tubules of the nephron.
A 1 only
B 1 and 3 only
C 2 and 3 only
D 1, 2 and 3
I am not able to understand this question......it Is really confusing.
