6.2: Using Veins and Venules – Student Edition (Human Biology)

Difficulty Level: At Grade Created by: CK-12

Begin this section with Activity 5-1: The Direction of Blood Flow. This activity effectively illustrates what veins are and what they do.

Review the vocabulary terms artery, arteriole, capillary, venule, and vein. Discuss how they work together to get blood with nutrients and oxygen to cells, transfer nutrients and oxygen to and remove wastes from cells, and then transport wastes, such as carbon dioxide away from the cells.

Review the Apply Your Knowledge and the Review Questions.

Throughout and at the end of the section, refocus students' attention to the key ideas using posters or overhead transparencies.

Observing Veins Students observe the veins in their hands after swinging and holding one of their hands at their side and above their head.
