Muscular System
The muscular system contains all the body muscles, that assist the bones in locomotion. Muscles are attached to the bones through tendons.
- Main organs: Muscles (skeletal, smooth, and cardiac).
- Smooth muscle (involuntary muscle) is present within the walls of blood vessels and thin organs like the stomach or intestines.
- Cardiac muscle (heart muscle) is an involuntary muscle tissue found only in the heart and is responsible for the pumping of the blood.
- Skeletal muscle (voluntary muscle) is a muscle tissue that is connected to the bones and participates in the functioning of different parts of the body. These muscles are also known as voluntary muscles as they are controlled by the nervous system in the body.
- Functions: Enables movement, maintains posture, generates heat, and supports various bodily functions like digestion and circulation.
Human Body
Human body is a single structure composed of billions of tiny components, which can be classified into four main groups: cells, tissues, organs, and systems. At the microscopic level, the cell is the most basic and fundamental unit that forms the foundation of the entire human body.
The human body is a highly organized system that performs various functions like movements, reproduction, growth, differentiation, respiration, digestion, and excretion. All these processes work together, in a balance, for the well-being of the individual and to sustain life.
