Meconium ileus, in newborns, may indicate the presence of cystic fibrosis
Cystic fibrosis is a genetic disorder mainly associated with cells capable of producing mucus. These cells are found in sweat glands, digestive system and lungs belonging to respiratory system. Thus, the abnormality in mucus production, in sticky and thick nature, disrupts the normal functioning of human body. They block the ducts and tubes, which can result in life threatening condition.
The mutation responsible for cystic fibrosis occurs in the gene CFTR, which is abbreviated form of Cystic fibrosis trans membrane conductance regulator. The primary function of gene is to regulate the exchange of fluids and salts present in the cells.
Meconium ileus refers to the inability of bowel movement in the newborn. This occurs due to thick and sticky mucus, which is indicative of cystic fibrosis, as discussed above.

Answer:
Homeostasis
Explanation:
Homeostasis is a mechanism of the body which involves negative feedback loops that helps the body to maintain a stable internal environment when there is an external or internal change.
An example of homeostasis in the human body is the regulation of the internal temperature of the body. When there is a change in the normal body temperature, for example, if your temperature drops sharply below 37 degrees Celsius, homeostasis kicks off in the body to maintain the normal body temperature. Homeostasis uses thermoregulation mechanism which triggers shivering to raise the body temperature in an attempt to return it back to normal.
Homeostasis also makes it possible for the body to maintain the balance of water and other substances in the body like calcium in our body. For example, when the calcium level drops below normal level, the parathyroid gland secretes hormone which helps in the increasing of blood calcium levels.
Homeostasis s a essential mechanism that helps keeps the body in a balance and functional state.
