| What does the cardiovascular system deliver? | oxygen & nutrients to the tissues of the body |
| What does the cardiovascular system remove? | waste products (carbon dioxide & lactate) |
| Thermoregulation | maintaining body temperature (to ensure you don't overheat) |
| Vasocontriction | narrowing the blood vessels to reduce blood flow (to increase temperature) |
| Vasodilation | widening the blood vessels to increase blood flow (to decrease temperature) |
| Sinoatrial Node (SAN) | sends an impulse to the right atrium causing the muscular walls to contract. The contraction forces blood from the atrium down into the ventricles |
| Atrioventricular Node (AVN) | slows down the signal from the SAN. This allows the ventricles to fill with blood before contraction |
| Bundle of His | a specialist muscle cell that transports impulses from the AVN (found in the walls of the ventricles) |
| Purkinje Fibres | allow the ventricles to contract which pushes blood out of the heart |
