The Gas Exchange System
- Sticky mucus forms in the lungs due to non-functioning CFTR channels.
- Sticku mucus cannot be cleared by beating celia.
- The mucus then traps dust and bacteria.
- Leading to the increase of chance of lung infection due to pathogens in the mucus
- The mucus blocks airways making gas exchange in the lungs less efficient

The Digestive System
- The pancreatic duct becomes blocked by sticky mucus, leading to the relase of digestive enzymes being reduced.
- The lower concentration of enzymes within the small intestine reduces the rate of digestion,
- Because of this food is not fully digested in the time it takes to pass through the small instestine.
- Therefore nutrients cannot be absorbed.

The Reproductive System
- In females, sticky mucus collects in the cervix, leading to mucus plug developing.
- Sperm cannot penetrate the mucus so the chance of contraception is reduced.
- Males often lack sperm ducts or if present they become particulary blocked by mucus.
- Leading to a reduction in the number of sperm present in each ejaculate.
