What are the 3 main functions of the skeleton?
The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
What is the function of the human body?
These many functions can be summarized in terms of a few that we might consider definitive of human life: organization, metabolism, responsiveness, movement, development, and reproduction.
What are three organs and their functions?
These are the main organs, as well as their primary function:
- The brain controls thoughts, memory and other organs.
- The heart pumps blood around the body.
- The lungs separate oxygen from the air and remove carbon dioxide from the blood.
- The stomach helps to digest food.
- The intestines absorb nutrients from food.
What are the 3 main functions of muscles?
The five main functions of the muscular system are movement, support, protection, heat generation and blood circulation:
- Movement. Skeletal muscles pull on the bones causing movements at the joints.
- Support. Muscles of the body wall support the internal organs.
- Protection.
- Heat generation.
- Blood circulation.
What is the primary function of this body system?
Body Systems, Functions, and Organs
| Body System | Primary Function |
|---|---|
| Reproductive | Reproduction |
| Nervous/Sensory | Communication between and coordination of all the body systems |
| Integumentary | Protects against damage |
| Muscular/Skeletal | Provides form, support, stability, and movement to the body |
What is the most important organ in your body?
Anatomy & Function The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.

What jobs do muscles?
Muscles pull on the joints, allowing us to move. They also help the body do such things as chewing food and then moving it through the digestive system. Even when we sit perfectly still, muscles throughout the body are constantly moving.
What are the body parts and their functions?
These are the brain, heart, kidneys, liver and lungs. The human brain is the body’s control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage and general perception of the world.

How are the different parts of the body working?
At each moment, your heart and lungs are working, and a variety of other things are occurring inside you, even as you sleep. Some of these you can feel but not control, such as digestion; others will forever elude your conscious detection. It is convenient to divide the many components of the body into systems based mainly on function.
When does the body perform its most effective functions?
In general, the body performs its functions least well at both ends of life – in infancy and in old age. During childhood, body functions gradually become more and more efficient and effective. During late maturity and old age the opposite is true.
What are the functions of the integumentary organ system?
The integumentary organ system includes the hair, nails and skin and acts as a barrier between the interior of the body and the outside world. It protects the body from damage and infiltration by microorganisms, and also keeps the fluids inside the body and helps maintain body temperature.
