แบบทดสอบระบบย่อยอาหาร

The digestive system starts in the mouth where food is broken down into smaller pieces through chewing and mixed with saliva. This process is the first step in the digestion of food and prepares it for further breakdown and absorption in the rest of the digestive system.

Exercising immediately after eating can cause indigestion or discomfort in the stomach due to the body's blood flow being directed towards the muscles being used during exercise, rather than towards the digestive system. This can result in symptoms such as bloating, gas, or stomach cramps, which are commonly referred to as "จุกเสียด" in Thai.

The tongue is responsible for mixing food with saliva in the mouth.

The correct answer is "ผลิตน้ำดี". The liver is responsible for producing bile, which helps in the digestion and absorption of fats in the small intestine. Bile also aids in the elimination of waste products from the body. Therefore, the liver's role in producing bile can be considered as its function in producing "good" or "healthy" fluids for digestion.

The correct answer is "กระเพาะอาหาร" (stomach). The stomach is responsible for both breaking down and temporarily storing food. It secretes digestive enzymes and acids to break down food into smaller particles, and it also contracts to mix the food with these digestive juices. The stomach then gradually releases the partially digested food into the small intestine for further digestion and absorption.

Pepsin is an enzyme that functions as a protease, meaning it breaks down proteins into smaller peptides. It is produced in the stomach and plays a crucial role in the digestion of proteins. Pepsin works by cleaving the peptide bonds between amino acids, which allows for the absorption and utilization of amino acids by the body. Lipase, rennin, and amylase, on the other hand, are enzymes that are involved in the digestion of fats, milk proteins, and carbohydrates, respectively.

The correct answer is the large intestine. The large intestine is responsible for the elimination of waste materials and undigested food from the body. It absorbs water and electrolytes from the remaining indigestible food matter, forming feces which are then eliminated through the rectum. The small intestine, on the other hand, is responsible for the absorption of nutrients from digested food.

Lipase is an enzyme that breaks down fats into smaller molecules, such as fatty acids and glycerol. It plays a crucial role in the digestion and absorption of dietary fats in the small intestine. Lipase is produced by the pancreas and is released into the small intestine where it acts on the fats present in the food. Therefore, Lipase is responsible for the breakdown of fats.

Amylase คือ เอนไซม์ที่ช่วยย่อยแป้งให้เป็นกลูโคส ซึ่งเป็นน้ำตาล ซึ่งจะช่วยให้แป้งที่เราทานเข้าไปในร่างกายสามารถดูดซึมและย่อยได้ง่ายขึ้น

The process of digestion in the stomach takes approximately 3-4 hours. During this time, the stomach uses its muscular contractions and digestive enzymes to break down the food into smaller particles and mix it with stomach acid. This allows for the absorption of nutrients and the elimination of waste products.
