Tricuspide valve
Takes blood from the right atrium to right ventricle
Pulmonary semilunar valve
Takes blood from the right ventricle into the pulmonary trunk
Systemic circuit
Supplies oxygenated blood to all tissues of the body and returns
it to the heart (LEFT SIDE)
Good blood is then taken to:
1) Pulmonary veins
2) Left atrium
3) Mitrol/Biscupid valve
4) Left ventricle
5) Aortic semilunar valve
6) Aorta
7) Entire body
Mitrol/bicuspid valve
Takes blood from left atrium to left ventricle
aortic semilunar valve
Takes blood from left ventricle into the aorta and then the rest of
the body
,Which vein takes the oxygenated blood to the left side of the
heart?
Pulmonary veins
Blood from ABOVE the diaphragm goes to the ___________
superior vena cava
Blood from BELOW diaphragm goes to the ___________
inferior vena cava
Mediastinum
Where the heart is located; space between the lungs
Base of heart
Wide, superior portion of heart, large vessels attach here; where
blood vessels come out
Apex
Tapered inferior end; tilts to the left
What is the size of the heart?
Adult = 10 oz, 3.5in wide at base; 5in from base to apex
- at any age, the heart is size of fist
Pericardium
Membrane/double-walled sac that encloses the heart
Structure of the pericardium
, 1) Fibrous pericardium
2) Serous pericardium (parietal and visceral layer and pericardial
cavity/fluid)
Fibrous pericardium
Outmost layer; tough, fibrous sac
Serous pericardium
Innermost later of pericardium
parietal layer of serous pericardium
Lines fibrous pericardium
Visceral layer of serous pericardium (epicardium)
Adheres to heart surface and outermost layer of heart itself
Pericardial cavity
Space between parietal and visceral layers of serous
pericardium; filled with 5-30mL of pericardial fluid
Pericardial fluid
Allows the heart to work smoothly without friction; prevents
friction so that we don't feel our heart working
Which layer of the pericardium is in contact with the heart?
Serous
Which layer of the serous pericardium touches the heart?
visceral layer
