Nutrient Transport in Animals

Question 1

Which statement best describes how nutrients from digested food are transported to the cells of the body?

Accepted Answer

Nutrients are absorbed through the walls of the small intestine into the bloodstream, which then carries them to cells throughout the body.

Answer

Nutrients are stored in the large intestine until the body needs them.

Answer

Nutrients are taken up directly by the muscles from the stomach.

Answer

Nutrients travel through the lymphatic vessels directly to the brain.

Question 2

Aisha eats a granola bar and drinks a cup of water before her piano lesson. After the food is broken down in her small intestine, which statement best explains how the glucose from the granola bar and the water she drank reach the cells in her right hand?

Accepted Answer

The glucose and water are absorbed into tiny blood vessels in the small intestine, travel in the blood pumped by the heart through arteries to the hand, and then leave the capillaries to enter the hand’s cells.

Answer

The glucose and water first travel to the liver through the portal vein, are stored there, and are later released into a special “nutrient pipe” that sends them straight to the hand’s cells.

Answer

Red blood cells carry the glucose and water inside themselves, move through the arteries to the hand, and then burst open inside the hand’s cells to release the nutrients.

Answer

The glucose enters the lymphatic vessels, while the water stays in the bloodstream; both travel to the hand through the lymph system and then directly into the hand’s cells.

Question 3

Which statement correctly describes how nutrients from digested food enter the bloodstream after passing through the small intestine?

Accepted Answer

Nutrients are absorbed through the walls of the villi into tiny blood vessels called capillaries, which then carry them to the heart.

Answer

Nutrients are broken down further by the liver before entering the blood through the gallbladder.

Answer

Nutrients are taken up by the large intestine and then travel directly to the heart through the lymphatic vessels.

Answer

Nutrients are filtered by the kidneys and then released into the bloodstream.
