one bone to another.

sacks called alveoli.
oxygen is delivered from the air through
the respiratory passages into the air
sacks in the lungs. Oxygen move int the
Respiratory Process blood in the capillaries. Carbon dioxide
moves from blood to air sacks through
respiratory passages and is expelled
through mouth or nose.

heart is a pump that has four cham-

1) Kidney- filters waste products (urea,

2) Ureter-connected to kidneys, urine
flows out of kidney through ureter
