Unit 3 Exam Review

Match the blood part to their job.

• Carry Dissolved Nutrients

• Plasma

• Clot Blood

• Red Blood Cells

• Carry Oxygen

• Platelets

• Fight Infections

• White Blood Cells

Match what the blood part with its structure (what it looks like)

• Has spiky branches

• Red Blood Cells

• Larger, disc shaped

• Plasma

• Liquid component of blood

• Platelets

• Smaller, flexible, disc shaped w/ dents

• White Blood Cells

How does the structure (shape) of red blood cells help them function (do their job)?

• The flexibility allows red blood cells to fit through capillaries and the dents allow them to carry more oxygen.

• Red blood cells have a thick outer layer to protect against damage.
• Red blood cells are square-shaped to maximize surface area.
• The spherical shape of red blood cells prevents them from deforming.

• Platelets

• Not being able to get nutrients

• White Blood Cells

Blood plasma is mostly made of...?

• Glucose

• Nitrogen

• Water

• Vitamins

Since plasma is mostly made of water what symptom might a person have if they are dehydrated?

• Less water means they would have thinner blood = faster flow of nutrients

• Less water would meant that they have thicker blood = slower flow of nutrients

• The blood would not be affected.
