If a body system such as the digestive system fails to work properly what would happen to the organism?

If the digestive system fails to function properly, the organism would struggle to break down and absorb essential nutrients from food, leading to malnutrition and energy deficiencies. This can result in weight loss, weakened immunity, and increased susceptibility to infections. Additionally, waste products may not be eliminated effectively, potentially causing toxicity and further health complications. Overall, the organism's overall health and vitality would be significantly compromised.
