What is the bottom chamber of the heart?

What side has the aorta artery and pulmonary vein
Right (Left Atrium + Ventricle)

Why does the atria have a thinner muscular wall?

The SAN is the heart’s natural what?

What is the P wave in a Electrocardiogram?
What represents the contraction
What is the T wave in a Electrocardiogram?
What represents ventricle repolarisation
What is a pulse oximeter?
Measures blood oxygen saturation with a sensor which shows light (amount of blood absorbed)
What is a Arterial Blood Gas Assessment?
Blood sample taken from the wrist to get saturation of oxygen in blood
What is a CapillaryBlood Gas Assessment?
Blood sample taken from the earlobe to get saturation of oxygen in blood
What is the blood pressure of a healthy 18-year old male?
120/80
What is the artery structure?
Thick wall, elastic fibres, smooth endothelial lining
