Short Essay On Human Digestive System

At the end of the esophagus, a muscular ring or valve called a sphincter (pronounced: SFINK-ter) allows food to enter the stomach and then squeezes shut to keep food or fluid from flowing back up into the esophagus.The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces.The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus.

The first step in the digestive process happens before we even taste food.

Just by smelling that homemade apple pie or thinking about how delicious that ripe tomato is going to be, you start salivating — and the digestive process begins in preparation for that first bite.

The large intestine's main job is to remove water from the undigested matter and form solid waste (poop) to be excreted.

The Digestive System The digestive system is a group of organs that perform the process by which food, containing nutrients, is eaten and broken down into different components.

The inner wall of the small intestine is covered with millions of microscopic, finger-like projections called villi (pronounced: VIH-lie).

The villi are the vehicles through which nutrients can be absorbed into the blood.Swallowing, done by muscle movements in the tongue and mouth, moves the food into the throat, or pharynx (pronounced: FAIR-inks). A soft flap of tissue called the epiglottis (pronounced: ep-ih-GLAH-tus) closes over the windpipe when we swallow to prevent choking.From the throat, food travels down a muscular tube in the chest called the esophagus (pronounced: ih-SAH-fuh-gus).This breakdown makes it possible for the digested material to pass through the intestinal wall into the blood stream. The digestive process contains many different steps that take place in many different organs. Digestion begins in the mouth, well before food reaches the stomach.When we see, smell, taste, or even imagine a tasty meal, our salivary glands in front of the ear, under the tongue, and near the lower jaw begin making saliva (spit).Waves of muscle contractions called peristalsis (pronounced: per-uh-STALL-sus) force food down through the esophagus to the stomach.A person normally isn't aware of the movements of the esophagus, stomach, and intestine that take place as food passes through the digestive tract.An acidic environment is needed for the digestion that takes place in the stomach.By the time food is ready to leave the stomach, it has been processed into a thick liquid called chyme (pronounced: kime).
