Flexibility
Range of movement at a joint Cardiovascular Endurance
- Deoxygenated blood then enters the right atrium
as it fills it forces the tricuspid valve open and blood flows into the right ventricle
- Blood is then ejected out of the right ventricle into the pulmonary artery which takes blood to the lungs for oxygenation. The semi-lunar valves close to stop backflow into the ventricle
- Gaseous occurs at the lungs and the blood becomes oxygenated
- Oxygenated blood then passes through the pulmonary vein to the left atrium
- Blood fills the left atrium and forces the bicuspid valve open. Blood enters the left ventricle
- Blood is ejected out of the left ventricle via the aorta in order to deliver oxygen around the body What is heart rate?
The number of times the heart beats per minute What is stroke volume?
cardiac output = heart rate x stroke volumne Define all parts of the heart
Pulmonary Artery
Pulmonary vein
Right atrium
Right ventricle
Inferior vena cava
Tricuspid valve
Semi-lunar valves
Septum
Left ventricle
Bicuspid valve
Left atrium
Pulmonary vein
Pulmonary artery
Aorta How is blood distributed around the body during exercise
Blood goes around the body
Delivers oxygen to working muscles
Muscles that need oxygen the most receive it the most instead of other areas What is an artery?
A blood vessel that carries oxygenated blood away from the heart Describe the structure of arteries
-narrow lumen to maintain high blood pressure What is a capillary?
Very tiny
