A&P Cardiovascular - Heart Flashcards
perfusion
The delivery of blood per unit per gram of tissue in units of mL/min/g - this maintains healthy pumping of blood to the heart
arteries
transport blood away from the heart
veins
transport blood to the heart
capillaries
smallest blood vessel with thin walls that allow for the movement of substances between blood and interstitial fluid
which side of the heart is responsible for receiving oxygen poor blood?
the right side receives oxygen poor blood and transports it to the lungs
which side of the heart is responsible for receiving oxygen rich blood
the left side receives oxygen rich blood and pumps it to the body
atrium
receives blood from veins
ventricle
receives blood from the atriums and pumps it into the arteries
the great vessels
the large arteries and veins that are directly connected to the chambers of the heart
where does the superior vena cavae drain blood from?
the head, neck, upper limbs, and superior trunk
where does the inferior vena cavae drain blood from?
lower limbs and inferior region of trunk
pulmonary circulation
movement of blood to and from the lungs for gas exchange
systemic circulation
movement of blood to and from the systemic cells
what are the layers of the heart?
fibrous pericardium, parietal layer of serous pericardium, and visceral layer of the serous pericardium (epicardium)
where is the heart located?
within the mediastinum of the thoracic cavity
fibrous pericardium
dense connective tissue that encloses the heart
parietal layer of the serous pericardium
simple squamous epithelium ith underlying layer of areolar connective tissue adheres to the inner surface of the fibrous pericardium
visceral layer of serous pericardium
simple squamous epithelium with underlying layer of areolar connective tissue forming the epicardium
pericardial sac
made up of the fibrous pericardium and parietal layer of serous pericardium which compose a loose bad around the heart
serous fluid
produced by the two layers of the serous pericardium
