The function of muscular system is to move our body, so if I had no muscle in my fingers I wouldn't have been able to type this answer.
For muscle tissue there are three types of tissues: skeletal, cardiac, and smooth muscle. They provide posture and body support, locomotion, and heat production.
Hope you understand what I said
The alveoli are lined with mucus and are surrounded by a network of blood capillaries. They have very thin walls for gases to be absorbed through. An individual air sac is called an alveolus. The layer of moisture in the alveoli allows gases to dissolve so that they can diffuse quickly.
I hope that helps you!
Can you provide the graph? I can't answer the question if I don't know what it is ^^
