circulation ( mini quiz )

Pulmonary

To do with lungs

Artery

Away from heart

Atriums

Receives blood

Ventricles

Chambers that pump blood out of heart

Veins

Brings blood into heart

Valves

Prevents backwards flow of blood

Septum

A wall of tissue that separates two sides of the heart

Deoxygenated blood enters the heart through the ________

Vena cava

After leaving the vena cava the ______ blood goes to the ____

Deoxygenated, right atrium

After leaving the right atrium the ______ blood goes through the ____ to get to the _____

Deoxygenated, atrioventricular valve, right ventricle

After being ____ out of the right ventricle the ______ blood makes its way through the ____-_____ ____

Pumped, deoxygenated, semi-lunar valve

The semi lunar valve takes the deoxygenated blood to the ______

pulmonary artery

The pulmonary artery then takes the _____ blood to the _____ to pick up ___

Deoxygenated lungs oxygen

After leaving the lungs the ______ blood re enters the heart via the _______

Oxygenated, pulmonary vein

After re entering the heart through the pulmonary vein the _______ blood is then taken to _______

Oxygenated, Left atrium

The ______ blood then leaves the left atrium via the _______ valves and arrives at the _____

Oxygenated, atrioventricular, left ventricle

Oxygenated, aorta

Name parts ABCDE

Aorta, right atrium, right ventricle, left atrium, left ventricle

Name parts ABCD

Vena cava, pulmonary veins, pulmonary artery, septum

Name parts AB

Semi - lunar valves , atrioventricular valves

Describe the structure of an artery and why each thing is there

• Narrow lumen - maintains high blood pressure

• Thick muscle layer - withstand high pressure surges

• Elastic layer allows artery to stretch and bend

OVERALL POINT - WITHSTAND HIGH PRESSURE SO BLOOD CAN MOVE FASTER

Describe the structure of a vein and why each thing is there

• large lumen - allows lots of blood to flow through

• Thin walls - doesn’t need to withstand pressure

• Contains valves - prevents back flow of blood on its way back to the heart

• Contains elastic layers but very thin - still able to bend and stretch but less as they are thin

OVERALL POINT - AS MUCH BLOOD BACK TO HEART AS POSSIBLE

Describe the structure of a capillary and why each thing is there

• overall extremely small - fits between cells

• Very thin walls - short diffusion path way

• No elasticlayer shirt diffusion pathway

OVERALL POINT - SDP

Pulmonary Arteries carry ____ blood

Deoxygenated

Pulmonary Vein carries ____ blood

Oxygenated
