Red blood cells carry oxygen to all cells in your
body.
 Red blood cells also carry away carbon dioxide, a
waste gas.

Muscle Cells move different body parts.
Muscle cells are bundled together to form strong
fibers. In the bundle muscles have greater
strength for movement.
There are 3 types of muscle cells:
Skeletal muscle
Cardiac muscle
Smooth muscle
SKELETAL MUSCLE
Skeletal muscles move your head, arms, legs,
fingers, and toes.
 Skeletal muscles work in pairs to move bones
back and forth.
 Skeletal muscles are voluntary muscles meaning
you can control their movement.

SMOOTH MUSCLES
Smooth muscles are found in the walls of organs
such as the stomach, intestines, and bladder.
 Smooth muscles are involuntary muscles
meaning you can not control their movements.

CARDIAC MUSCLE
Cardiac Muscle make up the walls of the heart.
 Cardiac muscle squeezes and relaxes without
stopping.
 Cardiac muscle are involuntary meaning you can
not control their movement.
