Blood vessels
Arteries = blood vessels with thick, muscular walls that transport blood from the heart to the organs 

Capillaries = very small blood vessels

Veins = blood vessels that transport blood from the organs back to the heart
- Valves = prevent blood from flowing back; they are present in many veins and in and around the heart

Coronary arteries = arteries around the heart

Coronary veins = veins that transport oxygen-poor blood from the heart to a vena cava

Blood pressure
= force with which blood pushes against the walls of blood vessels

Diastolic pressure = blood pressure during heartbeat pause; this is the lowest pressure

Healthy blood pressure for young people = around 110/70 millimetre of mercury
