oxygen and carbon dioxide.
Which side of the heart contains oxygen-poor blood? why?

Which vessels move blood away from the heart? What type of blood are they carrying?
Arteries take oxygen rich blood.
Which vessels carry blood to the heart? Which type of blood are they carrying?
Veins take oxygen poor blood back to the heart.
Explain how the structure of the capillary makes diffusion possible?
Because the capillary walls are very small.
What are the major components of blood? What are the functions of each?
Plasma – carry red blood cells
Platelets – help form blood clots
Red Blood Cells – Carry oxygen
White blood cells – fight disease
What is blood mostly made of?
