Respiratory System

The human body

Brain and nervous system

It does this via the spinal cord, which runs from the brain down through the back and contains nerves that branch out to every organ and body part. When a message comes into the brain from anywhere

in the body, the brain tells the body how to react.

Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by the spine (vertebrae).

The nervous system is like a network that sends messages to different parts of the body and receives messages back from the body.

How the Nervous System Works

The basic functioning of the nervous system depends a lot on tiny cells called neurons.

The brain is like a computer that controls the body's functions.

The brain has billions of them.

They have many specialized jobs. For example, sensory neurons take information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain and back to the rest of the body.

Senses

1.- Sound waves entering our ears and causing our eardrums to vibrate.

2.- These vibrations are then transferred along the tiny bones of the middle ear and converted into nerve signals.

3.- The cortex then processes these signals, telling us what we are hearing.

1.- Taste buds react to chemicals in foods. Taste buds react to sweet, sour, salty, bitter and umami.

2.- Messages are sent from the taste buds to the areas in the cortex responsible for processing taste.

1.- Light entering the eye forms an upside-down image on the retina.

2.- The retina transforms the light into nerve signals for the brain.

3.- The brain then turns the image right-side up and tells us that we are seeing.

1.- Each nostril react to chemicals we breathe in 2.- They send messages along specific nerves to the brain

1.- The skin contains more than 4 million sensory receptors that gather information related to touch, pressure, temperature, and pain.

2.- It sends it to the brain for processing and reaction.

The Human Body

Organization of the Human Body

The human body is made up of millions of cells.

The cells combine together to create tissue.

The tissues combine together to create organs.

And organs join together to create the different body systems.

The human body is the entire structure of a human being.

It is made up of organs that are part of different body systems that allow the human body to work.

Circulatory

system

GOAL

The circulatory system moves blood around our body.

Blood carries oxygen and nutrients to different parts of our body.

At the same time it collects waste that our body does not need.

Bones and Muscles

Our locomotor system consists of our skeleton (bones) and muscles.

It allows our body to move. It also protects our organs and keeps us upright.

Muscles

Skeleton (Bones)

It is made up of bones.

Bones are hard, rigid and strong.

The bones of our skeleton are held together by connections called joints.

A muscle is a soft and elastic organ that produces movement.

They are connected to the bones

and move them by contracting and relaxing.

TRIVIA TIME

They connect bones.

TRIVIA TIME

There are three types:

- Flexible joints that allow the bones to move (elbow).

http://www.abcya.com/skeletal_system.htm

http://www.anatomyarcade.com/games/WAB/WAB.html

There are 206 bones in a skeleton.

They are of various types:

- long bones (femur).

- flat bones (scapula).

- short bones (vertebrae).

JOINTS

There are 600 muscles in our bodies.

When muscles contract they get shorter,

but when they relax they get longer.

- Semi-flexible joints which only allow the bones to move a little (vertebrae in spine)

- Fixed joints don't allow the bones to move (joints in the skull).

There are two types:

- Voluntary muscles: when we want to move them, our brain sends a signal to the muscles (biceps to flex the arm).

They are a group of small bones called vertebra that form the spine.

The spine supports the whole skeleton.

- Involuntary muscles: when we cannot control them and

It is a group of flat bones that protect our brain.

Respiratory system

Our body needs oxygen from the air in order to survive.

We use the respiratory system to breathe in air.
