Title: BTEC Applied Science Unit 11 Assignment 2
Description: Unit 11: Physiology of Human Body Systems – Assignment 2 The Structure and Function of the Respiratory System Task 1 Collect measurements of peak flow from twenty different individuals. Ideally this should be 10 males and 10 females. Calculate the mean peak flow and the range for each of the two groups. Explain clearly what the term “peak flow” means. Describe how peak flow readings would be affected by asthma. Explain why peak flow readings would be affected by asthma. This provides evidence for P4 Task 2 Describe how a spirometer would be used safely to measure : Tidal volume Vital Capacity Oxygen consumption Use a spirometer trace to calculate the above measurements for one member of your group This provides evidence for P4 Task 3 Complete the evidence for P4 by completing the booklet This provides evidence for P4 Task 4 You must explain How the lungs are ventilated. How the tissues in the lungs assist the function. The need for a ventilation system in multi-cellular organisms This provides evidence for M3 Exam board is Pearson ALL ASSIGNMENTS I HAVE UPLOADED ARE DISTINCTION GRADED.

Unit 11- Assignment 2- P4
Peak flow - The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) is a person's
maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used
to monitor a person's ability to breathe out air
...
wikipedia
...
The bronchi and bronchioles are constricted, so air cannot flow along them as quickly
...
Take a deep breath and fill your lungs with air
...
Blow air out of your mouth into the meter as hard as you can in one
blow
...
Re-set the meter and take two more readings
...
Spirometer
Lung capacity: The volume of air breathed in and out the lungs depends on a number of factors
...
This graph shows some of the volume changes that occur in the lungs during breathing
...
The tidal volume is the volume of air breathed in and out
with a normal breath
...
5 dm 3
...
5 dm3
...
Even when you have breathed out as much air as possible, there is still about 1
...
This is called the residual volume
...
Using a spirometer: Lung volumes can be measures using a piece of equipment called a spirometer
...
The floating container rises and falls as the person breathers in and out
...
The container has and arm attached to
it
...
The pen draws a trace on some graph paper on a rotating drum
...
This stops the person re-breathing
carbon dioxide, which would increase their breathing rate
...
Flow rates: Medical practitioners may also wish to measure the rate at which air can be expelled
from the lungs when a person forcibly breathes out
...
The forced expiratory volume per second is the volume of air that can be
breathed out in the first second of forces breathing out
...
These volumes can be
measured using a peak flow meter
...
5dm3 to 2
...
So the oxygen consumption is:
3

7 = 0
