What organs are involved in the Nervous

System?

Brain, spinal cord and nerves.

What are the three jobs of the Nervous

System?

1. Receive information from the external

environment2. Respond to information

3. Maintain homeostasis

If you are reading a book, what part of your

brain is helping you?

Your Cerebrum

A nerve impulse enters through the ___________ of the

neuron.

Dendrite

What organs make up your central nervous

system?

Brain and Spinal Cord

What organs are involved in the

Circulatory System?

Heart, blood and blood vessels

What are the two jobs of the circulatory

system?

Bring needed substances to cells, and

to carry waste away from cells.

Your heart is a hollow ___________ that pumps blood your whole life.

Muscle

What are the four things that make up blood?

1. Red Blood Cells2. White Blood Cells3. Platelets4. Plasma

List how blood flows through the body starting

with the Right Atrium

Right atrium Right Ventricle Pulmonary Artery Lungs

Pulmonary Vein Left Atrium Left Ventricle

Aorta Body Vena Cavas

What are the two jobs of the respiratory system?

Moves oxygen into the body and removes carbon

dioxide and water.

How are your lungs able to take in so much oxygen?

Due to the large surface area of the alveoli.

What is the large muscle that controls your

breathing?

Diaphragm

This is the part of the respiratory system that is shared with the digestive

system, also known as your throat.

Pharynx

What is the process that allows the carbon dioxide in the blood to move into

the alveoli and the oxygen to move into the blood?

Diffusion

What is the job of the ventricle?

Pump blood out of the heart

What is the name of the wall that separates the sides of the heart?

The septum

Describe how the circulatory system and respiratory system are

related using the following words:

alveoli, lungs, oxygen, carbon dioxide, capillary,

heart, and body.

Example:When you inhale, you bring oxygen into your

lungs. Inside the lungs, the alveoli fill with the oxygen. The capillaries that cover the alveoli

contain blood high in carbon dioxide. The oxygen leaves the alveoli and enters the blood. The carbon dioxide leaves the blood and goes into the alveoli. The capillaries then carry the

oxygen rich blood back to the heart to be pumped to the body. The carbon dioxide in the

alveoli gets exhaled out of your body.

Describe how a nerve impulse travels through a neuron using the following words: dendrite,

axon, axon tips, cell body, nerve impulse, neurotransmitter,

synapse, dendrite of next neuron, electrical, chemical

A nerve impulse starts out in a dendrite. It then travels though the cell body and then into the axon. Then the impulse reaches the axon tips. In order

to cross the synapse, neurotransmitters are released to

change the impulse from electrical to chemical. The neurotransmitters go

across the synapse and reach the dendrites of the next neuron. The impulse converts back to an electrical impulse and the impulse continues on.

Fill in the blanks. A ________________ starts in a sensory

neuron. The impulse travels up to the brain through _______________. Then

the nerve impulse travels to a _______________. The motor neurons send the impulse to a _____________

which then contracts.

A nerve impulse starts in a sensory neuron. The impulse travels up to the brain through interneurons. Then the nerve

impulse travels to a motor neuron. The motor neurons send

the impulse to a muscle which then contracts.
