Describe what a red blood cell is,
where it's found, what its main function is and how it is specialised for its job |
found in the plasma (liquid part of the body
carries oxygen around the body small, lots of them, contain haemoglobin, large surface area, biconcave - short diffusion time as its thinner |
|
|
Describe what a white blood cell is,
where its found what its main function is and how its specialised for its job |
found in the plasma
defends against disease produces 2 types of antibodies 1. lymphocytes - specific |
|
|
Describe what a platelet is,
where its found what its main function is and how its specialised for its job |
found in the plasma
forms clots small, quick to move to where it's needed and there are lots |
|
Label the heart
|
1. Right
2. left 3. Aorta 4. Pulmonary Artery (blood TO lungs) 5.Pulmonary Vein (blood FROM lungs) 6. Left atrium 7. Left Ventricle 8. Atrioventricular valves (AV Valves) 9. Vena Cava 10. Right atrium 11. Right ventricle 12. Semi lunar valves |
|
|
What does the vena cava do
|
Carries deoxygenated blood TO the RIGHT atrium
|
|
|
Pulmonary artery
|
Carries de-oxygenated blood AWAY from the RIGHT ventricle to LUNGS |
|
|
Aorta
|
Carries oxygenated blood AWAY from LEFT ventricle - pumps it around whole body
|
|
|
Pulmonary Vein
|
Carries oxygenated blood TO the LEFT atrium
|
|
Explain each stage of 1 and 2 of the cardiac cycle
|
1. Atrial system
- atrial contracts and force blood into ventricles - semi lunar valves close - AV valves open 2. ventricle system - Ventricles contract and force blood into arteries - semi lunar open - AV valves close |

|
What is an artery
what is its job and how is it adapted to its job |
a blood vessel
carries blood away from the heart to organs |
|
|
what is a vein,
what's its job how is it adapted for its job |
a blood vessel
carries blood from organs to the heart |
|
|
What is a capillary
what's its job and how is it adapted to its job |
a blood vessel carries blood through organs, bringing blood to the cells in the organs
it is small enough to fit between cells and allow materials to pass through walls easily |
|
|
Why are the veins and arteries shown in different colours?
|
The arteries are shown in red as the blood has been through the lungs and so have been oxygenated by the alveoli
The veins are shown in blue as the blood hasn't been through the lungs and so still have CO2 in them and so are de-oxygenated. |
