Anatomy of the HEART
Intro to Sports Medicine
Mrs. Frasca

2. HEART FUNCTION To circulate blood around the body
Blood delivers oxygen, nutrients, and transports waste
All body systems are dependent on the heart

4. Basic Anatomy: Chambers
Four Chambers:
-Right Atrium
-Right Ventricle
-Left Atrium
-Left Ventricle

5. Basic anatomy: Valves
Heart Valves open and close allowing blood to flow to the appropriate places at the appropriate times
Heart Valves (4):
Tricuspid
Pulmonic
Mitral or Bicuspid
Aortic

6. Basic anatomy: nodes Nodes comprised of specialized
tissue that contain both muscle
and nervous tissue and are part of the
Cardiac conduction system!
Two Nodes of the heart:
Sinoatrial Node (SA node)
Coordinates contractions by sending
Electrical impulses that travel through the walls of the heart to make it contract.
Atrioventricular Node (AV node)
Receives electrical signal from SA node and delays it for about a 10th of a second then relays the ectrical signals to the atrioventricular bundle to deliver an impulse to the rest of the heart.

8. DRAW AND LABLE ACTIVITY!
 Pulmonary arteries
Aorta
Superior Vena Cava 
 Pulmonary Veins
 Left Atrium
Right Atrium 
 Aortic Valve
AV node 
 Mitral (Bicuspid valve)
----- Meeting Notes (10/13/14 10:14) -----
Students draw out heart
then lable structures one by one.
Tricuspid Valve 
 Left Ventricle
< Pulmonary Valve
Right Ventricle 
Inferior Vena Cava 

Add picture that has the direction of blood flow as a diagram… add to each slide where direction of blood flow is discussed.

11. Draw and label activity!
Blood Flow:

13. HEART sounds Lub Dub What are Doctors Listening For?
BICUSPID & TRICUSPID
VALVES CLOSING = LUB
PULMONARY & AORTIC
VALVES CLOSING = DUB
What are Doctors Listening For?
Two clicking sounds each beat as valves shut at two different times each beat. Extra clicks and whooshing sounds suggest that valve system is not sealing correctly and is malfunctioning!

14. hEART PROBLEMS HEART DISEASE: narrowing of
the small blood vessels that supply oxygen
to the heart– fatty plaque build up in the blood stream
HEART MURMER: a low grade sound that is caused by insufficient blood flow through the heart
HEART ATTACK: occurs when blood flow to apart of your heart is blocked for a long enough time that part of the heart muscle is damaged or dies
