The effects of cystic fibrosis include respiratory and digestive issues.
The correct answer is "respiratory and digestive issues." Cystic fibrosis is a genetic disorder that affects various organs in the body, primarily the respiratory and digestive systems. The disease causes thick, sticky mucus to build up in the lungs, leading to difficulty breathing, recurrent lung infections, and eventually, lung damage. It also affects the digestive system, blocking the pancreas and preventing enzymes from reaching the intestines to break down food properly. This can result in poor absorption of nutrients and weight loss.
