Background information I would give to the student: This question is a perfect example which shows that if you really understand the topic, it becomes easier to remember the facts for the questions relating to it. Although the majority of the lesson is described with reference to the gaseous exchange system, the impaired functioning of the digestive system in terms of the blockage of the pancreas and liver secretions is considered and discussed and the students are challenged on their understanding through a range of exam-style questions.

Mucus is normally slippery and protects the linings of the airways, digestive tract, and other organs and tissues. Visit our dedicated information section to learn more about MDPI. When a CFTR protein with the delta F508 mutation reaches the ER, the quality-control mechanism of this cellular component recognises that the protein is folded incorrectly and marks the defective protein for degradation.

Cystic fibrosis (CF) is the number-one life-shortening inherited disease of young people. This leads into the section of the lesson which considers the inheritance of cystic fibrosis in an autosomal recessive manner and then focuses on the change in the primary structure of the channel which results from one of over 1500 different gene mutations. Cystic fibrosis is a genetic disorder caused by a recessive allele. ; Daher, W.; Kremer, L.

CFTR is a type of protein classified as an ABC (ATP-binding cassette) transporter or traffic ATPase. How does cystic fibrosis affect the digestive system? Less than half the price of our monthly plan. My arguments against the abortion of a cystic fibrosis child are that children with the disease should be allowed to live because they wont have a long live and they should be taken care from professionals. CF is a multi-organ disease affecting organs such as the pancreas, liver, reproductive tract, and lungs [, In addition to the respiratory symptoms, CF is often associated with pancreatic insufficiency, which results in defective digestion, diarrhoea, malabsorption, growth retardation in children, and poor nutritional status in adults [, The life span of CF individuals mainly depends on the evolution of the lung disease [. ; Ribeiro, M.P. In CF, the inherited CF gene directs the body's epithelial cells to produce a defective form of a protein called. Spallanzani, University of Pavia, 27100 Pavia, Italy. Intracellular pathogens evolved to infect, colonise, and duplicate within host cells, managing to hide from the host immune system [, This lack of appropriate classical therapies has different causes, including antimicrobial resistance (AMR) which could have several mechanisms, such as the misuse of antimicrobials in both the healthcare and veterinary sectors.
