Answer:
The correct answer given below:
Step-by-step explanation:
Red blood cells contain the protein Haemoglobin. When red blood cells are old or injured, the spleen breaks them down and converts the heme from their hemoglobin into Bilirubin. The liver further converts it into Bile which is stored in the Gall bladder. When you eat fat, the cells of your small intestine release the hormone Cholecystokinin. Contraction of the Gall bladder forces the Bile into the Duodenum, where it emulsifies fats and aids in their digestion.
