Human Anatomy and Physiology 1
The Heart and
Cardiovascular
System
Mark D’Arcy (BSc
(Hons), MSc)
, Learning outcomes
1. Describe the basic anatomy of the heart including structure of
the muscle, chambers, valves, and the coronary system
2. Understand and explain the different parts of the cardiac cycle
3. Describe the mechanism of action and function of the cardiac
conduction system
4. Describe the basis and application of the electrocardiogram
5. Describe the role of Starling’s Law of the Heart in regulating the
intrinsic function of the heart
6. Understand the role of the heart as the pump of the cardiovascular
circuit
7. Understand the differences between the structures of arteries and
veins, and their roles in the cardiovascular system
, The cardiovascular system
• Functions
– transport of gases, nutrients,
hormones, water
– regulate body temperature
– immune protection
• 3 components
– Heart
– Vessels
– Blood
, The heart
• Anatomy
• Cardiac cycle
• Initiation of the heart beat
• Cardiac output
• Innervation
