The Respiratory System and Tissue Fluid for Applied Human Biology BTEC Level 3

A set of student notes on the following part of the spec. To the best of my knowledge from many emails back and forth with Pearson and careful review of the spec and PPQ’s so far.

Pearson BTEC Level 3 National Extended Certificate in Applied Human Biology

Unit 1: Principles of Applied Human Biology

A3 Cardiovascular and respiratory system
We will look at the relationship between the structure, function and processes of the cardiovascular and respiratory systems linked to health, looking at risk factors for certain conditions.
• The respiratory system structure and function:
o lungs, to include trachea, bronchi, bronchioles, alveoli
o lymph nodes, lymphatic vessels
o ventilation and gas exchange
o exchange of substances between blood and tissues
o formation of tissue fluid and lymph

• Causes and common symptoms of chronic obstructive pulmonary disease (COPD),

A6 Diagnostic techniques
• Basic methods, equipment, result format, unit of measurement and interpretation for the following diagnostic techniques:
o manual and automated observation of vital signs such as respiratory rate and temperature, including the normal ranges for these vital signs in adults
o observation of tissue perfusion and blood oxygen saturation
