A. Content Objective: How structure of arteries, veins and capillaries aids in the movement of molecules around the body.
B. Language Objective: Explain the structure of veins, arteries, and capillaries relate to their structure and how the cardiac cycle causes the heart to pump blood.
C. Syllabus Details:
i. Arteries convey blood at high pressure from the ventricles to the tissues of the body
ii. Arteries have muscle cells and elastic fibres in their walls.
iii. The muscle and elastic fibres assist in maintaining blood pressure between pump cycles
iv. Blood flows through tissues in capillaries. Capillaries have permeable walls that allow exchange of materials between cells in the tissue and the blood in the capillary
v. Veins collect blood at low pressure from the tissues of the body and return it to the atria of the heart
vi. Identification of the blood vessels as arteries, capillaries or veins from the structure of their walls
