The Heart and Circulation
- The Heart is mainly made
up of muscle tissue
- An ARTERY is a blood vessel carrying
blood AWAY from the heart.
- A VEIN is a blood vessel carrying
blood TO the heart
- A capillary is a very small blood vessel, very
thin to allow substances to move in and out
- It contains valves to make the blood flow
throughout the chambers without backflow
- A double circulatory system is when
blood travels through the heart
twice as it flows through the body
- The difference between ARTERIES and VEINS is
that....
- VEINS - Have a valve, thinner muscles
and walls, carries detox blood
- ARTERIES - Uses elastic pumps, the recoil
keeps pressure high, carries ox blood
- VEINS - Have a valve, thinner muscles
and walls, carries detox blood
