Cardiovascular diseases interfere most directly with the normal functioning of system?

Explain the difference between arteries and veins.

•Arteries carry blood AWAY from heart. Veins carry blood to the heart.

•Arteries are larger, more muscular and elastic than veins.

•Arteries carry blood under higher pressure than veins. •Veins have valves to prevent the backflow of blood. Arteries do not have valves.

Explain what occurs in capillaries and why.

The exchange or diffusion of substances into or out of the capillary.

Capillaries are extremely small and have a VERY thin lining that allows for diffusion to occur.

Identify the part of the heart being described.

1. Receives oxygenated blood.2. Wall that separates the right and left side

of the heart.3. Large artery that carries oxygenated blood

to the rest of the body.4. Veins that carry oxygenated blood from

the lungs back to the heart.5. Pumps out deoxygenated blood.

Blood Type Antigens Antibodies

AB

ABO

Fill in the table below with the correct antigens and antibodies for each blood type.

antigen A and antigen Bnone

anti-B antibodiesanti-A antibodiesnone

Both anti-A and anti-B antibodies

What makes blood type O the universal

donor?•Type O blood does not have any antigens, so they can be given to any blood type.

What makes blood type AB the

universal recipient?•Type AB blood has both A and B antigens, so they can receive any blood type.

Which of the blood types in the ABO system may safely be given to a person with AB blood?

1. O or AB, only 2. A or B, only 3. B or AB, only 4. A, B, AB, or O
