Answer 2

Answer:

Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide.
3. involuntary: A muscle movement not under conscious control e.g. the beating of the heart. striated: The striped appearance of certain muscle types in which myofibrils are aligned to produce a constant directional tension. voluntary: A muscle movement under conscious control e.g. deciding to move the forearm.
