What does blood do
Transports oxygen

What do platelets do and look like
Cell fragments that forms scabs and blood clots
What does plasma look like and do
Yellow liquid that carries minerals
Vein characteristics
Has valves so blood doesn’t back flow
Thin walls as blood is at low pressure
Flexible to push blood back to heart
Artery characheteristics
Have muscular walls so they don’t burst under high pressure of blood
Capillaries characteristic

Vena cava and pulmonary artery
What does LORD stand for
Left oxygenated right deoxygenated
What goes into left atrium from lungs
Pulmonary vein
What comes out left ventricle to the body
Aorta
What comes in right atrium form the body.
Vena cava
What leaves right ventricle up to lungs
Pulmonary artery
How to tell who’s fittest
Lowest heart rate resting
Lowest heart rate during exercise
Lowest recovery time
How do heart attacks occur
Coronary artery is blocked meanjng blood to heart muscles restricted causing no oxygen to cardiac muscle meaning heart muscle dies causing heart attack
