What this set covers
Digestion, circulation and breathing are covered together: small and large intestine, peristalsis, bile, arteries, veins and capillaries, heart chambers, double circulation, coronary arteries, platelets, plasma, trachea, alveoli and diaphragm.
- Common mix-up
- Students often mix up arteries and veins: arteries carry blood away from the heart at high pressure, while veins have valves and return blood to the heart at low pressure.
- Review tip
- Trace one drop of blood around the double circulation from the left ventricle and back, naming each vessel and chamber, then check your route against a labeled heart diagram.
