  1. 1. CARDIOVASCULAR SYSTEM Presented By: Philomen Prem MBA Pharma# 10 Under the Guidance: Sippy Sir CARDIOVASCULAR SYSTEM Presented By: Philomen Prem MBA Pharma # 10
  2. 2. 3 Functions of the Heart • Generates blood pressure • Routes blood – Heart separates pulmonary and systemic circulation • Ensures one-way blood flow – Heart valves ensure one-way flow
  3. 3. Functions of the Heart • Regulates blood supply – Changes in contraction rate and force match blood delivery to changing metabolic needs – Most healthy people can increase cardiac output by 300–500%
  4. 4. Chambers of the heart
  5. 5. Blood Circulation  Deoxygenated blood returns to the heart via the superior and inferior vena cava, enters the right atrium, passes into the right ventricle, and from here it is ejected to the pulmonary artery.  Oxygenated blood returning from the lungs enters the left atrium via the pulmonary veins, passes into the left ventricle, and is then ejected to the aorta.
  6. 6. Serous membrane Continuous with blood vessels
  7. 7. Coordination of chamber contraction, relaxation
  8. 8. The Heart: Cardiac Output Cardiac output (CO) Amount of blood pumped by each side of the heart in one minute CO = (heart rate [HR]) x (stroke volume [SV]) Stroke volume Volume of blood pumped by each ventricle in one contraction
  9. 9. Conduction system of the heart Heart contracts as a unit Atrial and ventricular syncytia help conduct electrical signals through the heart Sinoatrial (S-A) node is continuous with atrial syncytium S-A node cells can initiate impulses on their own; activity is rhythmic
