Thank you god for Smooth muscles

Did you know you have more than 600 muscles in your body? They do everything from pumping blood throughout 

the body to help you in your backpack heavy lifting. You control over certain muscles, while others - like your heart - do their work without thinking at all

Each muscle consists of the same material, a type of elastic tissue (sort of like this material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle

Smooth muscle - and sometimes also called involuntary muscle - and usually in the papers, or layers, with one layer of muscle behind the other. You can not control this type of muscle. Brain and body tell these muscles what to do without you even thinking about it. You can not use your muscles to make smooth muscles in your arm or jump in the air

But the smooth muscles in the work throughout the body. In the stomach and digestive tract, they contract (tighten) and relax to allow to make food journey through the body. Smooth muscle in handy if you're sick and you need to shake. Back muscles push the food from the stomach to come through the esophagus (say: IH-Sah-FUH-Goss) and out of the mouth

And are also found in the smooth muscle of the bladder. When you are comfortable, it allows you to hold in urine 

(Paul) until you get to the bathroom. After that contract so that you can pay the urine. These muscles are also in the woman's uterus, as a child develops. There they help to push the baby out of the mother's body when it is time to be born
