Answers
1) Mouth
2) Liver
3) Small Intestine
Answer:
The parts of digestive system are-
Mouth-Teeth, salivary glands, and the tongue are all parts of the mouth. The process of digestion starts in the mouth, where the teeth aid by breaking and grinding the food molecules, followed by saliva combining with the food particles. This is the starting of the digestive tract.
Pharynx- The pharynx is a fibromuscular, Y-shaped tube-like structure that is connected to the mouth's tip. It helps chewed food move from the mouth and through the esophagus.
Esophagus- The esophagus is a muscular tube that is 25 cm long and connects the throat to the trachea. It is the top portion of the digestive system and is primarily responsible for moving food particles from the mouth to the stomach.
Stomach- The stomach is a hollow, musculoskeletal organ that is located under the diaphragm on the left side of the abdominal cavity. It is a crucial organ that works by keeping food in storage, giving the body adequate time to digest meals, and producing the hydrochloric acid and digestive enzymes needed to keep the digestive process going.
Small Intestine- The small intestine is a portion of the lower gastrointestinal system and is a long, thin tube-like structure that is around 9 to 10 feet long. Just beneath the stomach, which is entirely coiled and has folds and ridges, lies the small intestine.
Large Intestine- The large intestine is a thick, long, tube-like organ that is between four and five feet in length. It may be found directly below the stomach and covers the lateral and superior margins of the small intestine. It works by soaking up water and aiding in the decomposition of waste to extract tiny nutrients.
Liver- The liver is a sizable, triangular-shaped, reddish-brown digestive organ that is situated to the right of the stomach. It works by digesting the food that has been absorbed from the small intestine and producing bile, which aids in the small intestine's ability to digest fat.
