The Human Circulatory System Flashcards
What is the blood on the left side of the heart?
= oxygenated
What is the blood on the right side of the heart?
= deoxygenated
Where does blood leave the heart ?
= arteries “away from the heart”
= this is high pressure: increases every time heart contracts
= continually moves foward between contractions
What artery carries blood from the heart to the lungs?
= pulmonary artery
=carries deoxygemated blood
What is the aorta?
= carries oxygenated blood from the heart to the bpdu
= aorta divides- these arteries carries the blood to differenr organs
What artery supplies blood to the kidney?
= renal ateries
Before blood reaches the organs where does it pass?
= aterioles
Where does oxygenated blood go once it reaches the organs?
= cappilaries
= site of gas exchange
= oxygen diffusing from the blood to the to the body cells
= co2 diffuses from body cells to blood
= blood pressure is lower and no longer surging in pulses
What are veins?
= carry deoxygenated blood away from the organs to the heart
= low pressure
= not surging in pulses
What are veins from the kidneys to the heart called?
= renal veins
What is the vena cava?
= veins connect into one large vein
= returns deoxugenated blood into the heart
What are the pulmonary vein?
= oxynegated blood travels from the lungs to the heart
What is the coronary artery?
= branches from the aorta
= supplies the heartmuscle with oxygen and nutrients
=
What does a closed system mean?
= blood remains in the blood vesells
What is a double system?
= passes through the heart twice in each circuit
= one circuit delibers vlood to heart to lngs
- one takes blood fro heart to the body
