What is an example of a smooth muscle?

Answer 1

Digesting Food, and if anyone knows more, please tell me for my science homework! thx <3 :)

Digesting food has nothing to do with smooth muscle, it only intervenes in the transportation of food throughout the digestive system (by means of peristaltic movement), actual digestion is made by other types of tissue.

That aside, contraction and dilation of pupils, blood vessels, and airways also involve smooth muscle. There's also the movements of the thoracic diaphragm, which enables respiration. During childbirth, tha pain the woman suffers are because of the strong contractions of the smooth muscle in the uterus that's trying to push the baby to the outside. Let's see... what am I missing... oh yeah, there's also the anal and bladder sphincters' dilation and contraction, they either enable or stop defecation and urination respectively. Swallowing as well, it makes use of pretty much every pharyngeal muscle.

So tl;dr:

1) Breathing

2) Contraction and dilation of blood vessesls, airways and pupils

3) Swallowing

4) Peristaltic movement

5) Childbirth

6) Urination

7) Defecation

8) Vomiting.

I have the feeling I'm missing some stuffs but that's all I can remember at the moment. EDIT: remembered after reading another answer, add Vomiting to the list

Answer 2

Smooth muscles are found in the bladder, uterus, veins, arteries, etc. The actions that result from this are involuntary, such as digestion and your heart beating.
