State that the coronary arteries supply heart muscles with oxygen and nutrients

Explain the relationship between the structure and function of arteries
• Thick wall to withstand high blood pressure.
• Thick outer layer of longitudinal collagen and elastic fibers.
• Thick layers of circular elastic and muscle fibers.
• walls stretch and recoil for the blood to go from the heart to the small intestine.
• Narrow lumen to help maintain the high pressure..

Explain the relationship between the structure and function of capillaries
• Has pores to allow plasma and phagocytes to diffuse in or out.
• Connects the vein and artery
• Moist and thin for diffusion and has a short diffusion distance.
• Narrow diameter and large quantity allow for a large exchange of materials through diffusion

Explain the relationship between the structure and function of veins
• Thin layers with a few circular elastic and muscle fibers.
• Thin walls to allow the muscles to squeeze the veins
• Thin outer layer of longitudinal collagen and elastic fibers.
• Valves for blood to stay and not flow backwards.
• Wide lumen to accommodate for the slow flowing of blood

State that the following are transported by the blood: nutrients, oxygen, carbon dioxide, hormones, antibodies and heat

State that blood is composed of plasma, erythrocytes, leukocytes, (Phagocytes and lymphocytes) and platelets.
