Human body systems

Human Body Systems...

The human body system consists of 3 systems(so far)...

1. Integumentary system

2. Nervous system

3. Skeletal system

Integumentary system


The integumentary system is basically about the skin, hair, and nails.

  • It helps maintain homeostasis( temperature regulation and keeps body stable according to the surrounding)
  • It creates sweat( it creates sweat, when your hot, probably because your body needs to cool down.
  • It releases unwanted substances like sweat and oils.
  • It also helps in protecting our insides( ex: the skin protects our bones)
  • Certain layers in the skin have specific jobs(ex: The Fat layer insulates heat in the body).

Nervous system


The general idea of what the nervous system performs is...

  • Sensory: when the nervous system monitors what happens outside and inside of you, using receptors.
  • Integration: interprets messages sent to your brain
  • Motor: responds to information that is being sent to you brain

The nervous system is later broken down into 2 different parts...

1. Central nervous system

2. Peripheral nervous system

  • Central nervous system...
-The brain and spinal cord makes up the central nervous system

-The central nervous system interprets the messages sent to your brain

-It also sends directions, how to react, to certain actions you perform

-It also consists of the involuntary(breathing) and voluntary(you can control the actions that you perform).

  • Peripheral nervous system...
This is broken into 2 parts as well...
  • Somatic nervous system- it carries messages to the central nervous system
  • Autonomic nervous system- it carries the messages away from the central nervous system

Skeletal system


The skeletal system is broken down into 5 different parts...

  1. Supports: it helps shape the body and also give the body support.
  2. Protects: the skeleton protects our vital organs(ex: heart, lungs, brain).
  3. Movement: the joints and muscles help the us to move around. The skeletal system works with the muscular system.
  4. Hemopoiesis: this is the production of red and white blood cells that takes place in the bone marrow
  5. Storage: calcium and phosphorus is stored or located in here. These material helps our bones to grow stronger.
