Provides:
- support 
- movement

muscles can only contract or relax, they work in antagonistic pairs

Organs: biceps, triceps, hamstrings

Slide 11 - Tekstslide

Reproductive System
Provides:
- Reproductive hormones
- Reproductive cells

These are different for both male and females. 

Organs: ovaries, uterus, testicles & penis

Slide 12 - Tekstslide

3.2 The Circulatory system

Slide 13 - Tekstslide

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.

Slide 14 - Tekstslide

Circulatory System
Provides your body with the transport of oxygen and nutrients around the body. 


Organs: heart, veins, arteries and capillaries 

Slide 15 - Tekstslide

How does this transport takes place?
By means of a pump (the heart).

This pump is connected to a large system of tubes that run all through the body. (bloodvessels).


Slide 16 - Tekstslide

Slide 17 - Tekstslide

Blood
Blood is made out of the following things:

  • Plasma:                           Water, nutrients, hormones, waste products
  • Red blood cells:          Hemoglobin for oxygen transport
  • White blood cells:      Defense against pathogens
  • Platelets:                        Helps to stop bleeding

Slide 18 - Tekstslide

3.3 The Heart

Slide 19 - Tekstslide

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.  

Slide 20 - Tekstslide

Aorta
pulmonary artery
pulmonary vein
vena cava
right atrium
right ventricle
left atrium
left ventricle
tricuspid valve
aortic  valve
mitral valve
pulmonary valve
septum
apex

Slide 21 - Sleepvraag

The Phases of the cardiac cycle
  • Atria contract → first peak, before the large peak
Pushes blood into the ventricles

  • Ventricles contract → large peak
Pushes blood out of the heart

  • Rest → last peak, after the large peak
Muscle relaxes, blood flows into the atria

Slide 22 - Tekstslide

What controls it.
Nerve cells in the right atrium produce electrical signals

Signal reaches both atria → contract

Signal runs down the wall and up the sides → ventricles contract → highest blood pressure

Moment without signal → rest → lowest blood pressure

Slide 23 - Tekstslide

Names of blood vessels
Arteries
named after the organ they go to
Veins
named after the organ they come from

Special mention: for the portal vein
Goes from the intestine to the liver. 
(Liver filters the blood)

Slide 24 - Tekstslide

Problems with the heart
Clots form and block the vessel

In the coronary artery → heart attack
In the brain → stroke


Slide 25 - Tekstslide

3.4 The Nervous system

Slide 26 - Tekstslide

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
neurons 

Slide 27 - Tekstslide

Your nervous system
Your nervous system is your bodies fast communication system:
  • Your CNS - Central nervous system (control system)
  • Your PNS - Peripheral nervous system (routers)


Slide 28 - Tekstslide

Signals
When your body observes stimuli from it's environment, the following cycle happens:
  • PNS - Your body receives a stimuli (senses)
  • CNS - Your brain/spinal cord coordinates a response.
  • PNS - Muscles / glands create a response


Slide 29 - Tekstslide

Neurones - Wires
Our body has 3 types of neurones:
  • sensory neurones - connects senses to the CNS
  • interneurones - the neurones within the CNS
  • motor neurones - connects the CNS to the effectors


Slide 30 - Tekstslide

3.5 The Spinal Cord

Slide 31 - Tekstslide

Learning goals
I can....
  • 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.

Slide 32 - Tekstslide

Reflexes
A reflex is also a response of your body, but then using your spinal cord as a coordinator instead of a your brain:
  • this is often used in cases of emergency



Slide 33 - Tekstslide

Synapses
Synapses are connections in your nervous system that use chemicals in stead of electricity:
  • synapses work with a chemical called neurotransmitters
  • the bag that holds the neurotransmitter is called a vessicle
