• Organ systems
• Digestive system
• Enzymes
• Skeletal system
• Respiratory system
• Muscular system
• Nervous system
• Reproductive system
• Circulatory system

LEARNING GOALS:

I can....

• describe how organs work together in organ systems
• list the organs belonging to the different organ systems
• describe the general function of each organ in the different organ systems

3.1 Organ Systems

Fit the correct organ systems to the correct picture

Digestive system

Skeletal system

Nervous  system

Circulatory system

Respiratory system

Muscular system

Fit each term with the correct organ system

Motor neuron

Lungs

Hamstring

• Aorta
• Valves
• Blood
• Plasma
• Red blood cells
• White blood cells
• Platelets
• Circulatory system
• Diffusion
• Arteries
• Capillaries
• Veins 
• Heart

LEARNING GOALS: I can....

• describe the general components of a transport system and why they are important.
• describe the different types of blood vessels and their differences.
• list the parts of the heart.
• list the path of the blood flow through the heart.
• list the different components of blood and their functions.

3.2 Circulatory System

What do you remember
about Blood

Vein

Artery

Capillaries

Aorta

pulmonary artery

pulmonary vein

vena cava

right atrium

right ventricle

left atrium

left ventricle

tricuspid valve

aortic  valve

septum

apex

• Heart
• Atrium
• Ventricles
• Portal vein
• Coronary Arteries
• Clots
• Stroke
• Heart attack

LEARNING GOALS: I can....

• describe how the electrical signal travels through the heart and causes the three phases of the cardiac cycle.
• describe how blood pressure is created by the heart.
• follow the path of the blood through the circulatory system.
• name the arteries and veins based on the organs they are connected to.
• describe the role of the valves in the heart and how they create the heart tones.
• describe how blockages in the circulatory system can cause major problems for the body.  
•

• Nervous system
• Brain
• Spinal cord
• Central Nervous system
• Peripheral nervous system
• Stimulus
• Receptor cells
• Impulse 
• Coordinator
• Effector 
• Response 
• Neurons
• Sensory neurons
• Interneurons
• Motor neurones 

LEARNING GOALS:

I can....

• explain the function of the nervous system
• describe the components of the central nervous system 
• explain the process wherein the nervous system detects information from the environment and reacts to it
• describe the functions of the three different types of

3.4 Nervous system

What is the difference between the Central nervous system and the Peripheral nervous system?

Stimulus

integration center

Sensory neuron

Inter neuron

Motor neuron

Receptor

Effector

• Reflexes 
• Spinal cord
• Synapses
• Vesicles
• Neurotransmitters

LEARNING GOALS:

• explain how reflexes are different than a normal nervous system response.
• follow the chain of events that take place during a reflex arc.
• explain how impulses are passed from one neuron to the next.
• explain the function of neurotransmitters in spreading impulses.
• describe how drugs can connect to receptors and disturb impulses.

3.5 Spinal cord

Explain what a reflex is

The synapse

Receptor

Impulse

Postsynaptic membrane

Presynaptic membrane

Neurotransmitter

Vesicles

Impulse continues

The function of synapses are to

1. let drugs pass through
2. coordinate responses
3. pass the impulse to multiple neurons
4. check if the impulse is important enough

Substances like nicotine and alcohol can be addictive because..

1. they make more neurotransmitters
2. they bind to receptors enhancing or blocking impulses
3. they cause synapses to not work at all
4. they block the feeling of pain
