Answer:
The correct answer will be option- Muscles do not get oxygen
Step-by-step explanation:
The respiratory system is a set of organs which work together to provide oxygen to the cells and exhale the product in the form of carbon dioxide.
In some medical conditions like pneumonia, cystic fibrosis and many others the respiratory system fails to work properly as a result of which the carbon dioxide gets accumulated in the blood.
The accumulation of blood also affects the transport of oxygen to the muscles which lead to less production of ATP in the muscles and cause "muscular dystrophy". The symptoms also include the bluish color of various organs of the body like eyes and lips.
Thus, option- Muscles do not get oxygen is the correct answer.
