Human Biology III (Cardiorespiratory Performance)

HUMAN BIOLOGY III (CARDIO RESPIRATORY PERFORMANCE) COURSE STRUCTURE
There are 7 lessons as follows:

1. The Science of Blood
2. Blood Pressure
3. Pulmonary Ventilation
4. Gas Exchange & Transport
5. Blood Flow & Gas Transport
6. Cardio Respiratory Control
7. Cardio Respiratory Disease

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.

SUMMARY OF COMPETENCIES DEVELOPED
On successful completion of the course you should be able to do the following:

• Explain the how blood affects human health, including its nature, how it works and its significance.
• Explain blood pressure and its relationship to health and fitness.
• Explain the physiology of pulmonary ventilation.
• Explain the physiology of gas exchange and transport.
• Explain relationship between blood flow and gas transport in the body.
• Explain the physiology of cardio-respiratory control.
• Explain the physiology of cardio-respiratory disease.

WHAT THE COURSE COVERS
Here are just some of the things you will be doing:

• Explain the functions of blood, including transportation, regulation and protection, including examples of the roles played by some of the different blood components in the performance of these functions.
• List fifteen different substances which are transported by blood.
• Explain the movement of blood through the human body, including:
  • where it moves
  • how it moves
