What side of the heart is oxygenated blood?
Left side (right on paper)
What side of the heart is deoxygenated blood?
Right side (left on paper)
Flow of blood through the heart?
Blood flows into the right atrium, moves to the right ventricle, and is pumped to the lungs to pick up oxygen. Oxygen-rich blood then returns to the left atrium, flows into the left ventricle, and is pumped to the rest of the body through the aorta
What is cardiac output?
the volume of blood pumped by the heart in one minute
How do you calculate cardiac output?
Stroke volume X heart rate
How does a heart beat?
What is systolic?
The top number when messuring blood pressure. This is the pressure when the blood is abkle to force its way through the artery
What is diastole?
The bottom number pon
What makes the lub noise?
When the AV valves shut at the beginning of ventricular systole
What makes the dub noise?
When the AV valves shut at the end of systole/beginning of diastole
What are blood vessels?
They form a network of tubes carrying blood between the heart and body cells
What are Arteries?
They carry blood from the heart under very high pressure
Away from the heart
Have thick elastic walls
Carries oxygen rich blood (except the pulmonary artery)
What are Arterioles?
Smaller branched arteries that attach to capillaries
What are Capillaries?
Connect arterioles to venules
thin walled and porus (lots of holes)
Allow materials such as gases and fluids to be exhanged with the body cells
What are Veins?
carries blood to the heart under low pressure
thinner walled than arteries
contain one way valves to prevent backflow
Carry oxygen poor blood (except the pulmonary veins)
What are Venules?
theyre small veins that join larger vein to capillary
How do you messure blood pressure?
a sphygmomanometer
What is unhealthy blood pressure?
above 140/90
What is a systemic system?
What is a pulmonary system?
What are different heart and vessel problems?
What are components of blood?
