What is the large intestine primarily responsible for?

The large intestine plays a vital role in the digestive system, with its primary responsibility being the removal of water from waste products. As food is digested, it passes through the small intestine where nutrients are absorbed. The remaining waste then enters the large intestine, which extracts water and salts from this material, helping to consolidate it into a more solid form before excretion. This process is crucial for maintaining hydration and electrolyte balance in the body.

While the other options mention important functions, they do not accurately capture the primary role of the large intestine. For instance, absorbing nutrients is primarily the function of the small intestine. The production of blood cells occurs in the bone marrow and not in the large intestine. Bile, produced by the liver, is stored in the gallbladder and has no significant role in the large intestine's functions. Therefore, the large intestine's main responsibility indeed revolves around removing water from waste products.
