1. Blood FLOW
Blood flows from atrium to the ventricles
Systemic circuit – Blood flow between the body and heart
This blood leaves through the aorta
Pulmonary refers to lungs
Pulmonary arteries to the lungs
Pulmonary veins take blood away from the lungs to the heart
From the body, blood returns to the right atrium

2. Away from the Heart:
Pulmonary artery, Aorta
To the heart:
Pulmonary vein, Vena Cava (body veins)
Blood carries – oxygen, nutrients

3. Heart Rate Zone
How much exercise you need to do to strengthen your heart without hurting it
Lower target rate = 145 bpm: how much exercise you need to benefit your heart
Upper target rate = how much exercise you can do before you hurt your heart
Resting Heart rate: Your heart rate when you’re not exercising
Low resting heart rate – Your heart doesn’t work as hard – so when you start exercise it won’t increase as much
A lower resting rate indicates a heart in better shape
