Three patients in an intensive care unit are examined by a doctor. One patient has brain damage from a severe stroke. Another had a heart attack that severely damaged their heart muscle. The last patient has a disease that attacks and breaks down connective tissue in the body. All three patients have stabilized and will survive, but only one will have a full functional recovery through regeneration. Which one and why? (this is NOT the one with the liver don't put that one) thank you:)​
