Final answer:
The three types of muscle tissues in the human body are skeletal, smooth, and cardiac muscle tissues. The two common functions of muscles are movement and maintaining posture.
Step-by-step explanation:
The three types of muscle tissues in the human body are skeletal, smooth, and cardiac muscle tissues.
Skeletal muscle tissue is attached to the bones and is responsible for voluntary movement, such as walking or lifting objects. It is under conscious control.
Smooth muscle tissue is found in the walls of organs and blood vessels. It is responsible for involuntary movements, such as digestion or contraction of blood vessels.
Cardiac muscle tissue is found only in the heart and is responsible for pumping blood. It has characteristics of both skeletal and smooth muscle tissue.
The two common functions of muscles are movement and maintaining posture. Muscles allow us to move our body parts and perform various actions. They also help maintain the alignment and stability of our body while standing, sitting, or moving.
