El Aparato Digestivo y la Digestión | Videos para Niños

Summary

In this educational video, viewers are introduced to the digestive system and the process of digestion. The journey of food through the body is explained, starting from the mouth where digestion begins, passing through the pharynx, esophagus, and stomach, and ending in the small intestine where nutrients are absorbed. The role of the liver and pancreas in aiding digestion is highlighted. The video also covers the large intestine’s role in absorbing water from undigested substances, which then forms feces. The video concludes with a lighthearted reminder of the human body’s fascinating yet sometimes unpleasant processes.

Takeaways

• 😀 The digestive system transforms food into simpler substances called nutrients.
• 😀 Nutrients are transported by the blood to be used by the body and converted into energy.
• 😀 The digestive system is a long tube that processes food, starting with the mouth.
• 😀 The teeth in the mouth cut and grind food, which then travels through the pharynx.
• 😀 The pharynx is a shared cavity for both the digestive and respiratory systems.
• 😀 The esophagus carries food from the pharynx to the stomach.
• 😀 The stomach mixes food with gastric juice to aid in digestion.
• 😀 Digestion finishes in the small intestine, where nutrients are absorbed.
• 😀 The small intestine is about 7 meters long and performs the final stages of digestion.
• 😀 Waste that cannot be digested travels to the large intestine, where water is absorbed and feces are formed.

Q & A

What is the purpose of digestion in the human body?

The purpose of digestion is to transform food into simpler substances called nutrients, which are then transported by the blood to be used by the body for energy.

What is the digestive system composed of?

The digestive system is made up of a long tube through which food travels, and includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus.

What role do the teeth play in digestion?

The teeth cut and grind the food, which begins the process of digestion in the mouth.

What is the pharynx and what role does it play in digestion?

The pharynx is a cavity shared by both the digestive and respiratory systems. Food passes through the pharynx after being chewed before moving on to the esophagus.

What is the function of the esophagus in digestion?

The esophagus is a tube that carries food from the mouth to the stomach, allowing it to continue its journey through the digestive system.

How does the stomach assist in digestion?

The stomach is a widening of the digestive tract that mixes food with gastric juices, breaking it down further before it moves to the small intestine.

What happens in the small intestine during digestion?

In the small intestine, digestion is completed. Juices produced by the liver and pancreas help transform food into nutrients, which are then absorbed into the blood through the walls of the small intestine.

How long is the small intestine, and why is its length surprising?

The small intestine is almost 7 meters long, which is as long as a soccer goal. It is surprising because it fits inside the human body despite its length.

What happens to food that the human body cannot use?

Food that the body cannot use passes into the large intestine, where it is stored and processed. Water is absorbed from these substances, and they form feces.

What is the final step of digestion before waste is expelled from the body?

The waste, now formed into feces, passes through the large intestine and is expelled from the body through the anus.
