2. Move movement possible

3. Move food through the digestive system with smooth muscle.

4. Muscle movements aids the flow of blood through the veins.

5. Muscle actions move fluid through the ducks and tubes associated with other body systems.

6. Also generates body heat keeping us warm.]]> 2021-10-19 14:48:37 UTC https://padlet.com/p1111748/4otm2ym90f49ohb1/wish/1827464756 Muscle Fatigue p1111748 https://padlet.com/p1111748/4otm2ym90f49ohb1/wish/1831709505 Muscle fatigue is a symptom where muscles perform worse overtime, this can be caused by a number of things such as age.]]> 2021-10-20 21:40:33 UTC https://padlet.com/p1111748/4otm2ym90f49ohb1/wish/1831709505 Spasm p1111748 https://padlet.com/p1111748/4otm2ym90f49ohb1/wish/1831722632 A spasm is a sudden involuntary contraction of muscle ]]> 2021-10-20 21:49:00 UTC https://padlet.com/p1111748/4otm2ym90f49ohb1/wish/1831722632 Clonic vs Tonic Muscle Spasms p1111748 https://padlet.com/p1111748/4otm2ym90f49ohb1/wish/1831792782 A tonic spasm is brief, often painful, unilateral muscle contractions lasting for thirty seconds to three minutes
