Circulatory system

Chapter 5.2 Moving blood through the body (pages 109-118)

1. Identify and Label structure of the heart, blood vessels, valves and chambers

2. Describe and compare the function of blood vessels

3. Explain how the heart transports nutrients around the body via pulmonary and system circulation

Success criteria

1. Identify and Label structure of the heart, blood vessels, valves and chambers

   Types of Valves and why? prevent backflow

   • Pulmonary -from pulmonary artery into right ventricle

   • Aortic/semilunar - from aorta into left ventricle

   • Triscuspid - from right ventricle into right atrium

   • Mitral (bicuspid) - from left ventricle into atrium

   vessels

   atria - receives blood

   ventricle - pump blood to upper and lower body

   • thicker/muscular → need to contract

   • right ventricle goes to lungs less bigger → needs less force

   • left goes to whole body =bigger →needs more force

   vena cava - carries blood from upper and lower body towards right atrium

   Pulmonary vein - carries blood from lungs towards left atrium

   Aorta - carries blood from left ventricle to cells of body

   pulmonary artery - carries deoxygenated blood from right ventricle towards lungs

2. Describe and compare the function of blood vessels

   Veins - carry blood towards heart (usually deoxygenated blood except pulmonary vein)

   Capillaries - link between arteries and veins

   • Enables cells to get requirements from blood and pass waste onto blood

   • Structure 1 cell thick → allow substances to pass between blood and surrounding cells

   arteries carry blood away from heart ( usually oxygenated blood except pulmonary artery)

3. Explain how the heart transports nutrients around the body via pulmonary and system circulation
