Title: Cardiovascular System


1
Cardiovascular System
2
Functions of the Cardiovascular System
  • Transport
  • Immunological
  • Homeostasis

3
Cardiovascular System
  • Circulating fluid within the transportation
    system of a human is called?

4
Cardiovascular System
  • Complex system of vessels

Powered by an incredibly strong muscle
5
The Heart
  • Location
  • Size
  • Avg. contractions

6
  • Pericardium
  • Function
  • 4 major chambers
  • Atria
  • Ventricles
  • Septum

7
Circulation
  • Two separate pumps
  • Right side pulmonary circulation
  • Low O2 ? High O2
  • Left side systemic circulation
  • High O2 ? Low O2

8
Blood Flow Through Heart
9
  • Heart Valves
  • Four valves
  • Atrioventricular valves
  • Bicuspid valve (left)
  • Tricuspid valve (right)
  • Semilunar valves
  • Pulmonary semilunar valve
  • Aortic semilunar valve
  • Chordae tendonae

10
Blood Vessels
Arteries Capillaries Veins
11
  • The Heart Associated Great Vessels
  • Aorta
  • Pulmonary arteries
  • Vena cava
  • Pulmonary veins

12
Blood Pressure
  • Force of blood on the arteries walls.
  • Measured in mm/Hg
  • Systolic force felt on arteries when ventricles
    contact.
  • Diastolic force felt in arteries when the
    ventricle relax.
  • Adult avg. blood pressure 120/80
  • sphygmomanometer

13
  • Conduction System
  • Intrinsic conduction system (nodal system)
  • Special tissue sets the pace
  • Sinoatrial node
  • Atrioventricular node
  • Atrioventricular bundle
  • Bundle branches
  • Purkinje fibers

14
  • The Heart Conduction System
