Cardiovascular system (lecture) Flashcards
Perfusion
The delivery of blood per unit time per gram of tissue mL/min/g
The heart is effective at
Providing adequate perfusion to maintain the health of all body cells
Blood vessels include:
Arteries
Veins
Capillaries
Arteries: Transport blood away from the heart
Transport blood away from the heart
Vein:
Transport blood to the heart
Capillaries
Sites of exchange
The heart has how many chambers
4
Which side receives deoxygenated blood and where does it pump it to?
Right, the lungs
Which side receives oxygenated blood and where does it pump it to?
Left, The body
Pulmonary circulation
Includes movement of blood to and from the lungs for gas exchange
Systemic Circulation
Includes movement of blood to and from the systemic cells in the body
Coronary Circulation
Includes movement of blood to and from the wall heart
Where does gas exchange happen
The tissues in the heart wall
Coronary veins transport what?
Deoxygenated blood away from the heart wall
Coronary arteries transport ?
Oxygenated blood to the wall of the heart
Pericardium
Fluid filled sac that surrounds and protects the heart
What are the three layers of the Pericardium
Fibrous
Parietal
visceral
Fibrous Pericardium
Dense irregular connective tissue that encloses the heart but does not attach to it. Attaches at the diaphragm (inferiorly) and large arteries (superiorly)
Parietal pericardium
Simple squamous epithelium that adheres to the inner surface of the fibrous pericardium
