Final answer:
The gallbladder secretes bile to the duodenum to break down fats. Bile is formed by the liver and stored in the gallbladder. The pancreas produces most fat-digesting enzymes. Both the liver and pancreas contribute to the digestion of fats. The correct answer is C.
Step-by-step explanation:
c. The gallbladder secretes bile to the duodenum, which uses it to break down fats. It is considered an accessory organ because food does not directly pass through it.
Bile is formed by the liver and stored in the gallbladder. The pancreas produces most fat-digesting enzymes. Both the liver and pancreas contribute to the digestion of fats.
Bile is formed by the liver. It is a digestive juice crucial for the breakdown of fatty components in food within the duodenum of the small intestine. The gallbladder is a sac-like organ that stores and concentrates bile produced by the liver and secretes it into the small intestine as needed for digestion. The pancreas also contributes to digestion by secreting digestive juices containing enzymes that digest fats, carbohydrates, and proteins into smaller molecules.
Regarding the production of most fat-digesting enzymes, the answer is the pancreas. It secretes digestive juices that contain enzymes to digest fats, among other substances. While the gallbladder does play an important role in digestion by secreting bile to help break down fats, it does not produce the enzymes itself.
Bile is formed by the liver. Among the options provided, option B is the correct answer. The liver is a vital organ in the human body responsible for various functions, one of which is the production of bile. Bile is a yellowish-green fluid that plays a crucial role in the digestion and absorption of fats in the small intestine. The liver produces bile continuously, and it is then stored and concentrated in the gallbladder, which is not listed as an option in this case.
Bile contains bile salts, cholesterol, bilirubin, and other substances. Its primary function is to emulsify fats, breaking them down into smaller droplets to facilitate the action of enzymes that digest fats. The emulsification process increases the surface area of the fat particles, allowing lipase enzymes to efficiently break them down into fatty acids and glycerol. This breakdown is essential for the absorption of fat-soluble vitamins and nutrients in the small intestine. Additionally, bile helps in the elimination of waste products like bilirubin from the body.
While the pancreas does play a role in digestion by producing enzymes, it is not directly responsible for the formation of bile. The spleen, on the other hand, is primarily involved in filtering blood and is not a part of the digestive system.
