Blood composition and functions

Start with the components

Begin with a Blood mind map that shows plasma, red blood cells, white blood cells and platelets alongside blood functions. Several maps share that title, so look at their content to find one that suits your study. The note Functions of the blood also introduces the main components and describes plasma as the liquid that carries substances in blood.

Use the map for an overview, then read the note to add detail. You can return to the map as you work through the rest of the page.

Focus on cells and functions

The White Blood Cell (WBC) mind map looks more closely at leucocytes, including where they are made, their shape and their role in fighting disease. Other Blood maps include red blood cells, platelets and plasma, with functions such as transport, defense and clotting.

For another way to study these terms, use the flashcard deck The Blood. Its prompts cover plasma, plasma proteins and functions of the blood system. Compare the prompts with a map as you work through them.

Use quizzes and maps together

After studying a general map, try Blood quiz or Biology - Blood Components. Use the questions as a starting point for checking what you remember, then return to a relevant map or note to study a topic again.

For a narrower focus, the page also lists Blood Clotting and Leukocytes quizzes. A blood clotting mind map and the White Blood Cell (WBC) map give you related material to study alongside them.

Connect to the unit

Blood composition and functions is a section of the Circulatory System unit in Biology and natural sciences. The Circulatory System mind map links blood with transport around the body and protection against disease. It also describes blood being pumped away from the heart, giving a broader context for the blood resources on this page.
