Talk:Hypophyseal portal system

clarification needed
Explain/clarify why the word "tolerate" is used in this sentence: "The fenestrae structure of the hypophyseal portal system needs only a small amount of hormones to tolerate a rapid exchange between the hypothalamus and the pituitary gland to stimulate an accurate effect in the respective target organs in the body." Should the world be "enable" or "tolerate"? — Preceding unsigned comment added by 209.212.5.67 (talk) 21:48, 8 October 2014 (UTC)
