What is a long and narrow muscular tube that relaxes and contracts moving swallowed food into the stomach?
The long and narrow muscular tube you’re referring to is the esophagus. It connects the throat to the stomach and uses coordinated muscle contractions, known as peristalsis, to propel swallowed food downwards. The esophagus plays a crucial role in the digestive process by ensuring that food reaches the stomach efficiently.

What is the function of the muscle in the stomach?
It contractS and relaxes to churn the food and mix it with the bile and other digestive enzymes.
What muscular organ squeezes food into chyme?
The stomach mixes food, swallowed saliva, and gastric juices into a substance called chyme.
When the cardiac sphincter relaxes food enters the?
The cardiac sphincter or aka GE junction contracts at the distal end of the esophagus. So food enters into the stomach when the cardiac sphincter is relaxed.
What pushes food into the stomack?
Peristalsis, a series of coordinated muscle contractions, helps push food from the esophagus into the stomach. These contractions create a wave-like motion that propels the food forward through the digestive system. Additionally, the lower esophageal sphincter relaxes to allow food to enter the stomach and then contracts to prevent backflow.
What makes the sound of the stomach rumbling?
Stomach rumbling is caused by the movement of gas and fluids in the gastrointestinal tract as it contracts and relaxes during digestion. The sound is amplified when there is little food in the stomach, allowing the air and fluids to move more freely.
Where does food go immediately after it is swallowed?
After food is swallowed, it travels down the esophagus, a muscular tube connecting the mouth to the stomach. The process is facilitated by a series of coordinated muscle contractions called peristalsis. Once it reaches the stomach, the food is mixed with gastric juices for further digestion.
What is pyloric pump?
The pyloric pump is a muscular valve located between the stomach and the small intestine, specifically at the junction of the pylorus of the stomach and the duodenum of the small intestine. Its main function is to regulate the flow of partially digested food from the stomach into the small intestine. The pyloric pump contracts and relaxes to control the release of chyme (partially digested food) into the small intestine for further digestion and absorption. Dysfunction of the pyloric pump can lead to issues such as gastroparesis or delayed gastric emptying.
What hole allows food from the stomach into the small intestine?
The hole that allows food from the stomach into the small intestine is called the pylorus. It is a muscular valve located at the lower end of the stomach. When it relaxes, it allows the partially digested food (chyme) to pass from the stomach into the small intestine.
After chewing the food is swallowed and passes down the to the .?
After chewing, the food is swallowed and passes down the esophagus. It travels through this muscular tube via a series of contractions called peristalsis. Eventually, the food reaches the stomach, where it undergoes further digestion.
What structure do mammals have that performs the same function as the gizzard?
Mammals have the stomach that performs a similar function to the gizzard. The stomach in mammals contracts and grinds food with the help of stomach acids and muscular movements to break down food particles for digestion.
Is the stomach mechanical digestion or chemical digestion?
It is both: Mechanical: The stomach is a muscular sack. It contracts and relaxes, sloshing and squeezing the food inside to break it down and to ease the job of the 'chemicals'. Another example is how many birds swallow stones to enhance the crushing and churning in their stomachs. Chemical: The conditions and enzymes within the stomach contribute to chemical digestion. Hydrochloric acid, for example, creates an acidic environment that denatures proteins; whilst enzymes such as pepsin react at a molecular level with peptides to cleave them apart.
Food when swallowed enters?
When food is swallowed, it first enters the esophagus, a muscular tube that connects the throat to the stomach. From there, rhythmic contractions called peristalsis push the food down into the stomach, where it is mixed with gastric juices for further digestion. The process of swallowing is coordinated by various muscles and involves the epiglottis, which prevents food from entering the windpipe.
