- The circulatory system
- The blood,heart and blood vessels
make up the circulatory.
- It removes waste
chemicals like carbon
dioxide from the cells to the
lungs and other wastes
from cells to the kidneys
- The circulatory system
transports useful things
like oxygen from the
lungs to the cells and
digested food from the
small intestine to the
cells
- The circulatory system also transports
hormones, antibodies and blood proteins
- The blood,heart and blood vessels
make up the circulatory.
- Blood circulation
- The heart is the pump
which circulates the blood
through the blood vessels
- Blood flows in arteries away
from the heart to the different
organs of the body
- Blood flows back to the
heart in veins
- The smallest blood vessels that
connect arteries to veins are
capillaries
- Cells are very close to
capillaries so they receive a
good supply of oxygen and food
materials from these capillaries,
this also enables them to have
their carbon dioxide and other
wastes removed efficiently
- The heart is the pump
which circulates the blood
through the blood vessels
- A double circulation
