Word of the day: stoma
A stoma in medical terms is an artificial opening between a hollow organ and the outside of the body constructed to permit the passage of body fluids or waste products.
Two types of operation give rise to such a stoma: a clostomy which creates an opening for faeces or a urostomy which creates an opening for urine.
I had never come across the word stoma until I read a novel called “Unexpected Lessons In Love” [my review here].
