Lesson 31: Circulatory and Respiratory systems

Hi,

This set of powerpoint slides covers two chapters. They slides are clear and useful in understanding difficult concepts such as how skeletal muscles move blood upwards (against gravity) in the vein.

Here is a list of salient points to look out for in this lesson:

• parts of the circulatory system
• heart structure and the path of blood flow within it
• how the heart functions as a double pump
• functions of the systemic and pulmonary circulations
• how the kidney is involved in regulating the volume of blood and blood pressure
• the components of blood and their functions
• definition of respiration
• cellular respiration and breathing/gaseous exchange between lungs and the environment
• parts of the human respiratory system
• breathing mechanism
• components of cigarette smoke and the harmful effects of these components

Lymphatic system and its functions are not in our syllabus.

Functions of the brain in regulating the breathing rate is also taken out of our syllabus. However, the effect of increased carbon dioxide concentration in blood triggering increase in breathing rate is very much in our syllabus.
