Digestive System

Front

What connects the mouth to the stomach?

Back

esophagus

Answer explanation

The esophagus is the muscular tube that connects the mouth to the stomach, allowing food to pass through. The epiglottis prevents food from entering the windpipe, while the pylorus is a part of the stomach, and the tongue aids in swallowing.

Front

Nutrients from digested food are absorbed in which digestive organ?

Back

Small Intestine

Answer explanation

Nutrients from digested food are primarily absorbed in the Small Intestine, where the majority of digestion and absorption occurs, making it the correct answer. The Stomach mainly breaks down food, while the Large Intestine absorbs water.

Front

What does the esophagus do?

Back

it pushes food into the stomach

Answer explanation

The esophagus is a muscular tube that transports food from the mouth to the stomach. Its primary function is to push food into the stomach through coordinated contractions, making "it pushes food into the stomach" the correct choice.

Front

What absorbs water?

Back

large intestine

Answer explanation

The large intestine is primarily responsible for absorbing water from indigestible food matter, making it the correct choice for the question about water absorption.

Front

absorbs nutrients

Back

small intestine

Answer explanation

The small intestine is the primary site for nutrient absorption in the digestive system. It efficiently absorbs vitamins, minerals, and other nutrients from digested food, making it the correct answer.

Front

Why do we eat?

Back

Front

A disease in which stomach acid goes up into the esophagus, causing burning pain and sometimes ulcers.

Back

GERD (acid reflux)

Front

absorbs water into bloodstream

Back

large intestine

Answer explanation

The large intestine absorbs water from indigestible food, helping to form solid waste. The gall bladder stores bile, and the liver processes nutrients, but it is the large intestine that primarily absorbs water into the bloodstream.

Front

Digestive organ, where most chemical digestion and absorption of food take place organ.

Back

small intestine

Answer explanation

The small intestine is the primary digestive organ where most chemical digestion and nutrient absorption occur, making it the correct answer. The pancreas and liver play supporting roles but are not the main sites for these processes.

Front

large muscular sac that continues the mechanical and chemical digestion of food

Back

stomach

Answer explanation

The stomach is a large muscular sac that plays a crucial role in the mechanical and chemical digestion of food, breaking it down before it moves to the small intestine for further digestion and nutrient absorption.
