“Saddle Up That Cell” from The Circulatory Story written by Mary Corcoran; illustrated by Jef Czekaj

See the red thing that looks like an inner tube without the hole? It’s an erythrocyte, and it’s one of the three cellular components, or formed elements, of blood. (We’ll meet the other components later.) An erythrocyte is also known as a red blood cell, and it’s your ride. This red blood cell is just one of millions found in a drop of blood. These cells carry oxygen. No, they don’t carry it in a suitcase or a backpack. Instead, the oxygen attaches to a chemical called hemoglobin that’s found in red blood cells. With hemoglobin’s help, blood can transport oxygen to all parts of the body, including cells and tissues, which need a constant supply of oxygen (O2 ) in order to work. Nice job, Red!

Which piece of text evidence best shows the meaning of transport?

• “looks like an inner tube without the hole”

• “It’s an erythrocyte”

• “cells carry oxygen”
