If Henles loop were absent from mammalian nephron which of the following is to be expected
Urine will be more dilute because of concentration of urine due to counter current mechanism. loop of henle of juxtra glomenular nephrons take part in counter current mechanism. So if the loop of henle will absent then that counter mechanism will not take part in system so there will be no issues of concentration of urine.
So, the correct option is 'The urine will be more dilute'.
