TEST
50% MULTIPLE CHOICE
50% OPEN QUESTIONS
10 MINUTE GLOSSARY IS OPTIONAL
Slide 2 - Tekstslide
CHECKLIST IN MAGISTER
respiration
ventilation
gas exchange
the heart
bloodvessels
blood
Slide 3 - Tekstslide
RESPIRATION
- function
- types
- chemical formula
- how does it work in the body
- warmblooded vs coldblooded
- red-& white muscle tissue
Slide 4 - Tekstslide
What is respiration?
The release of energy in cell, this happens in the mitochondria.
K.P. 62
Slide 5 - Tekstslide
What do we need it for?
working your muscles
transporting chemicals
absorbing food (active transport)
sending messages along nerves
buidling cells for growth
controling your body temprature
K.P. 63
Slide 6 - Tekstslide
Types of respiration:
aerobic respiration
anaerobic respiration
K.P. 73-74
Slide 7 - Tekstslide
Slide 8 - Tekstslide
Slide 9 - Tekstslide
warmblooded vs coldblooded:
remember from last year?
Slide 10 - Tekstslide
VENTILATION
- types
- steps
- organs of the respiratory system
Slide 11 - Tekstslide
K.P.68
Slide 12 - Tekstslide
Put the organs in the correct order
Air enters
the body
Gas exchange
Nasal cavity
Alveoli
Pharynx
Larynx
Bronchi
Bronchioles
Trachea
Slide 13 - Sleepvraag
Thoracic inhalation:
air is sucked into the lungs
intercostal muscles contract
ribs pull the plearul membrane open
the plearul membrane pulls open the lungs
ribs move up
Slide 14 - Sleepvraag
Thoracic exhalation:
air is pushed out of the lungs
intercostal muscles relax
ribs push the plearul membrane closed
the plearul membrane pushes the lungs closed
ribs move down
Slide 15 - Sleepvraag
Abdominal inhalation:
air is sucked into the lungs
abdominal muscles contract
the diaphragm moves down
the plearul membrane pulls open the lungs
the diaphragm pulls the pleural membrane open
Slide 16 - Sleepvraag
Abdominal exhalation:
air is pushed out of the lungs
abdominal muscles relax
the diaphragm pushes the pleural membrane closed
the pleural membrane pushes the lungs closed
the diaphragm moves up
Slide 17 - Sleepvraag
Slide 18 - Tekstslide
GAS EXCHANGE
- alveoli
- how does gas exchange happen
- where does it happen
- respiratory diseases
Slide 19 - Tekstslide
moisture the alveolus
High oxygen concentration.
High carbon dioxide concentration.
one cell layer thick
cappilaries around the alveoli
oxygen goes into the red blood cells
oCarbon dioxide goes into the air
Red blood cell transport gasses
Slide 20 - Sleepvraag
DISEASES:
ASTHMA
BRONCHITES
EMPHYSEMA
LUNG CANCER
DAMAGE FROM SMOKING/DRUGS
Slide 21 - Tekstslide
THE HEART
- parts & functions
- how does it work?
Slide 22 - Tekstslide
one way valve
As you can see, a valve only opens in one direction
Slide 23 - 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 24 - Sleepvraag
BLOODVESSELS
- different types
- various bloodvessels in the body
Slide 25 - Tekstslide
What route does paracetamol take before it reaches the brain?
Slide 26 - Tekstslide
Blood vessels types
Arteries - carry blood
away
from the heart
Veins - Carry blood
back
to the heart
Capillaries - go to every cell in the body (oxygen and co2 exchange)
Slide 27 - Tekstslide
Wall
Pressure
Speed
Valves
Artery

Slide 28 - Sleepvraag
BLOOD
- compostion
- parts and functions
Slide 29 - Tekstslide
Slide 30 - Tekstslide
Red blood cells
Main function: Carry oxygen
Red pigment: Haemoglobin, allows them to carry oxygen
Don't have a nucleus (more space!)
Slide 31 - Tekstslide
White blood cells
Function: Destroy pathogens
Pus: Dead WBC and the bacteria they killed
Do have a nucleus, don't have a fixed shape
Can squeeze through openings
Slide 32 - Tekstslide
Platelets
Not cells! Fragments of cells that have broken up
Important in
clotting
