what are the 3 types of heart vessels?
capillaries, veins and arteries
what does the circulatory system do ?
transport oxygen and nutrients
what are the top chambers of the heart called?
The atria ( atrium singular)
what are the bottom chambers called?
ventricles
valves
prevent the blood from going backwards ensuring that it flows in the correct direction
where does blood first flows into the heart?
vena cava and the pulmonary vein
in terms of chambers where does blood first enter?
left artium and right artium
where is the pulmonary vein coming from
the lungs
what type of blood is in the pulmonary vein?
oxygenated blood
where is the vena cava coming from
looped around the body back to heart
what type of blood is in the vena cava?
De-oxygenated blood
when the atria contract they…
push the blood into the ventricles
in a instant the ventricals push the blood back up…
into the pulmonary artery and aorta
where does the pulmonary artery go to?
the lungs since it is de-oxygenated blood
where does th aorta lead to
the oxygenated blood goes around the body to oxygenate it
what are the pacemaker cells
located in the rightt atrium and they produce electrical impulses causing the contractions
Artificial pace maker
small device just under the skin that sends electrical current to the heart
ARTERY
any vessel that carries blood away from the heart
vein
any vessel that carries blood to the heart
PULMONATRY ARTERY IS STILL A ARTERY
it still carries blood away from the heart
how does the heart get its own oxygenated blood
smaller arteries around the organ called coronary arteries
