1. All coats and bags are stored out of the way.
2. No food / drink in the Lab- no exceptions.
3. During experimental processes all stools are stored
safely.
4. Everyone participates.

4. *
*Unit overview and how to achieve
*Identify the fluids found within human bodies
*Demonstrate body fluids diagrammatically
*Categorise different types of fluid

5. *Be here, on time, equipped!
*If you don’t understand something please ask
*Read the chapter in Stretch and Whitehouse book BEFORE the
lesson –ISBN 9781846907470
* Lesson resources will be on Canvass the day before your
lesson with me

*ROUND 1: Row 1 - Identify the body fluids you already know
*ROUND 2: Move right by three places and row 2 now identify the
fluids you are aware of.
*ROUND 3: Collaborate and Distinguish where they are found

8. *
*You will be split into 4 even groups, you will need to find some
space
*Draw a rough outline of a member of your group on the paper
provided (be very careful of clothes!)
*Combine your dating results and label as many fluids as you can
on the body
*Use correct biological terminology
*S&C – label the parts of the body as you go along in a different
colour

9. *
*Give your team a point for each fluid you
labelled.
*Give your team an extra point if you labelled
the following……

10. * Aqueous humour - the limpid fluid within the eyeball between the cornea and the lens
* Cytoplasm – the jelly like substance in the cell between the cell membrane and the nuclear
envelope
* Tears - made from water, mucin, lipids, lysozyme, lactoferrin, lipocalin, immunoglobulins,
glucose, urea, sodium, and potassium
* Plasma- Straw coloured watery fluid with 91% water, 7% plasma proteins, 25 different
dissolved salts, waste products, glucose, amino acids, hormones, antibodies and enzymes
* ECF (extracellular fluid) - liquid containing proteins and electrolytes including the liquid in
blood plasma and interstitial fluid
* ICF (intracellular fluid)- liquid contained inside the cell membranes
* Succus- digestive juices in the stomach for breaking down molecules
* Urine- liquid waste produced by the kidneys
* Mucous - aids in the protection of the lungs by trapping foreign particles that enter it, in
particular, through the nose, during normal breathing
Bonus point – what is the scientific name for the process of crying?
Answer - lacrimation

11. Fluids only INSIDE the body Fluids that are SECRETED from
the body

13. Use the space provided to interpret what
the graph shows.

14. If a Male weighed 80kg
How many kg would the
following categories be?
*Total body fluid
*Intracellular fluid
*Extracellular fluid
*Blood volume (plasma).
*

15. *
Q1: Find total body fluid
60% of 80kg TBW
50% = 40kg 10% = 8kg 60%= 48kg TBF (Total Body Fluid)
Q2: Find ICF value
ICF = 2/3 of TBF 1/3= 48÷3= 16kg 2/3= 16kgx2 ICF=32kg
Q3: Find ECF value
ECF= 1/3 of TBF
ECF= 16kg
Q4: Find Blood Volume
blood volume = 20% of ECF
ECF= 16kg 10% of 16kg=1.6kg 20%=3.2kg
Blood Volume= 3.2kg

17. *
*Locate a copy of BTEC Level 3 Health and Social Care Book 2.
*Read pages 148 – 155
*We are developing our knowledge on the intracellular fluids
found within the body.
*You will need to know about the differences between an
animal cell and a plant cell.
