Cardiac anatomy and physiology SPHS AP Biology

Normal cardiac anatomy Atrium are thin walled Ventricles thick muscular walls Left ventricle thicker than right Pulmonary Valve and Aortic Valve are exactly the same Tricuspid Valve and Mitral Valve are NOT identical.

Trace blood flow Which artery had deoxygenated blood?

Circulatory System anatomy What is the ‘job’ of the heart? How much blood do you have? Blood donation A, B, AB, O + or -- All oxygen is not used up the first time through the body. Hands only CPR

Capillary system

Coronary Artery Anatomy How does the heart get oxygen and nutrients to its own cells?

Coronary Artery disease- adult Blockage to coronary artery Fat, plaque and body’s response to those Cuts off blood flow to heart tissue Myocardial infarction “Heart Attack” What else is in this angiogram?

Cardiac stent vs Coronary Artery Bypass Graft (CABG)

Cardiac Conduction System The heart has an electrical system within it to coordinate the contraction in a timely manner.

Electrocardiogram (EKG)

1901 to present

Embryology

Fetal Heart Circulation Blood to baby through umbilical cord- carrying oxygen and nutrients Lungs filled with amniotic fluid Ductus Arteriosis open between Pulmonary Artery and Aorta Foramen Ovale open between Right and Left Atria

When things go wrong . . . Transposition of the Great Arteries d-TGA

Arterial Switch Operation

Coronary Artery Reimplantation

All done on a heart this size!!

When things go wrong . . . Hypoplastic Left Heart Syndrome HLHS
