How does this system work with other systems?

The Skeletal System
Most of the muscular system exists for the exclusive purpose of interacting with the skeletal system. Muscles move bones in relationship to each other whenever you move your legs or arms. Smaller muscles move your jaws and fingers.
The Nervous System
The nervous system can be viewed as complex information-possessing systems whose input is the senses and whose output is the muscles. Sometimes the muscles act as input to the nervous system in sensors such as the golgi sensors, which tell us when muscles are overextended.
The Circulatory System
The circulatory system brings nutrients to the muscles and takes away wastes. The circulatory system also carries hormones that regulate muscular activity. The pump for the circulatory system is the heart--a muscle.
The Digestive System
The muscular system interacts with the digestive system in several places. The muscles of the jaw masticate food, and then muscles along the esophagus move food from the mouth to the stomach. Muscles along the intestines move digesting food along, and muscles control sphincters that isolate the sections of the digestive system.
The Respiratory System
The main interaction between the muscular system and the respiratory system is the diaphragm: a large, flat muscle that separates the lungs from the intestines. It is the movement of the diaphragm that causes the lungs to inflate and deflate.
The Endocrine System
When your muscles need energy, a signal will be sent to your brain to release more insulin from your pancreas, which will create more energy to be available for use.

Muscular System

-Organs
The three major organs in the muscular system is: Smooth Muscular tissue, Skeletal muscles, and Cardiac muscles
-Smooth Muscular tissue
Smooth muscle tissue function is usually involuntary. Smooth muscles tissue pushes food along the digestive tract and controls the flow of blood through blood vessels
-Skeletal Muscles
Muscle tissue can be skeletal, which helps hold the skeletal frame together, provide strength and mobility and enables humans to walk upright.
-Cardiac Muscles
The heart is made up exclusively of cardiac tissues and is one of the most muscular organs in the body,

The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Also the muscular system’s second function is the maintenance of posture and body position. Muscles often hold the body still or in a particular position rather than to cause movement. The muscles responsible for the body’s posture have the greatest endurance of all muscles in the body. The muscles hold up the body throughout the day without becoming tired. The final function of muscle tissue is the generation of body heat. Many small muscle contractions within the body produce our natural body heat.

Muscles make up 40% of your total body weight.

It takes half as long to gain muscle than it does to lose it.

The smallest muscles are found in the middle ear.
