The body is made up of 3 main types of muscles: skeletal muscles that connect through the tendons to our bones, heart muscle that is only found in the heart, and smooth muscle that covers blood vessels and some organs, such as the intestine and the uterus.
Muscles are what gives us almost complete control over our movements.
They are made up of muscle cells (fibers) that receive a signal from the nervous system, which by contracting the fibers allows the presence of force and movement, this produces almost all the movements we perform.
The muscular contraction is divided into 3: The first two shorten the muscle fibers and lengthen them generating opposite force, the biceps are shortened and the triceps are lengthened or relaxed, or when the muscular relationship is reversed, it is lowered, and the last is type contraction which creates a stabilizing force, which does not generate a change in length in the muscle fibers, but keeps the muscles rigid, the latter is what helps us in our posture, to stay on our feet.
Muscles, when working, use energy and create heat, providing more or less 85% of body heat and leave their mark on almost everything we do so it is.

how does the human body work?
The human body is composed of three main types of muscles, the first is the skeletal muscle that connects through the tendons to our bones, the second is the cardiac muscle that is found in the heart and the last is the smooth muscle that lines the blood vessels and certain organs. The skeletal muscles form the majority of the muscular system and make up about 30 to 40% of the body's weight and generate most of its movement. The cardiac and smooth muscles are administered by the nervous system that makes the heart beat approximately 3 billion times which supplies the body with oxygen and blood.

The human body does many functions: the muscular system has over 650 muscles covers the body and is the reason we can do a lot of functions like smile, run, jump and others. This muscular system it's made up of skeletal muscle, cardiac muscle and smooth muscle, all of them are a perfect team that work for us. They recieve signals from the nervous system and it produces almost all the movements we make. Skeletal muscles make up about 30-40% of the body's weight and generate most of its motion and are connected to the somatic nervous system wich give us almost complete control over their movements.

- How does the human body work?
Our body works because we have more than 650 muscles, so we can carry out different activities.
The muscular system has three main muscles, skeletal system, cardiac system, and smooth system; they are made of cells (fibers); When these cells (fibers) contract, movements or forces are generated that allow us to make any movement or be in balance.
Skeletal muscles connect through tendons to our bones. The cardiac and smooth muscles are controlled by the autonomic nervous system, it causes our hearts to beat and supply blood and oxygen to the body.

The human body work to complete system, the work is muscular, neuronal is a bigger system perfect coordinate, the human body is simple and complex in actios so eat, breathe, walk, sleep and others, this simple actions in actually are complex so every system joins to meet, for example the run, jum is the system muscular, sleep is system neuronal, why the human body is perfect forever.

the body works with the muscular system, which is composed of skeletal muscle, cardiac muscle and smooth muscle, are made up of muscle cells bundled tightly together. these reive signals from the nervous system than contract the fibres, wich in turn generates force and motion this produces almost all the movements we make

Every time we take a step, 200 muscles work in unison to make the body respond positively. The nervous system is made up of 3 main types of muscles. Skeletal muscle: connecting through the tendons. Cardiac muscle - found only in the heart. Smooth muscle that covers the blood vessels and some organs.

The human body is the set of physical structure and organs that make up the human being.
The human body is made up of the head, the trunk, the upper extremities, arms and the lower extremities, legs. As for its main chemical elements, it can be highlighted hydrogen (63%) and oxygen (25%.

1 found it interesting that the heart is what spreads heat in our body through our blood. 1 thing I am wondering about is how do people accumulate the different types of cells, I know they say through practice but what organs or things in the body allow them to grow while you practice.

The human body performs different actions, which are possible thanks to the mucular system, it is a network of 650 muscles in the all body hman, that is made up of three systems: a cardiac, muscular and smooth muscle system that together with the nervous system allows movement.
