Heart + Blood Flashcards
What circulatory system is the heart
A double circulatory system
Left and right hand side
Is always opposite
What does the right ventricle do
The right ventricle pumps deoxygenated blood to the lungs
What does the left ventricle do
The left ventricle pumps blood to the body
Where and what does the aorta do
The aorta is on the left hand side so it delivers oxygenated blood to the body
Where and what does the pulmonary vein do
The pulmonary vein is on the left hand side so it contains oxygenated blood from the lungs
Where and what does the pulmonary artery do
It is on the right hand side so it delivers deoxygenated blood to the lungs
Where and what does the Vena Cava do
It is on the right hand side so it contains deoxygenated blood from the body
What type of blood is on the right hand side of the heart
Deoxygenated blood
What type of blood is on the left hand side of the heart
Oxygenated blood
What do you valves between the atrium and ventricle do
They prevent the back flow of the blood and open to let blood through
What is the heartbeat controlled by
A group of cells in the right atrium that acts as a pacemaker
What are artificial pacemakers
Artificial pacemaker are electrical devices used to correct irregularities in the heart rate
Name characteristics for arteries
Arteries take blood away from the heart
Arteries are under high-pressure with a pulse
They have thick permeable walls and a small lumen
They have no valves and carry oxygenated blood (except the pulmonary artery)
Name characteristics of veins
Veins take blood to the heart
Blood in the veins is on the low pressure and flow smoothly
Veins have thinner walls are not permeable and a large lumen
Valves in the veins prevent back flow of blood and carry deoxygenated blood
