lab quiz 2- heart chapter review

what is the position of the heart using anatomical terms

within the mediastinum, posterior to sternum/medial to lungs

which structures prevent the mixing of oxygenated and deoxygenated blood

interatrial and interventricular septa

left ventricle supplies

vena cava supply

right ventricle supplies

pulmonary veins supply

aorta

right atrium

pulmonary trunk

left atrium

the systemic circuit handles blood flow to

the pulmonary circuit handles blood flow to

to and form body and systemic tissues

to and from lungs

the following carry oxygenated or deoxygenated blood

pulmonary trunk/arteries

aorta

pulmonary veins

vena cava

deoxygenated

oxygenated

oxygenated

deoxygenated

what are the pectinate muscles

muscular ridges found within the atria and auricles

what are trabeculae carneae

the muscular ridges found in the ventricles

what superficially divides the ventricles

the interventricular sulcus

what internally divides the left and right ventricles

the interventricular septum

what is the entire path of blood through the cardiac system

vena cava/coronary sinus, RA, right AV valve, RV, pulmonary valve, pulmonary trunk, pulmonary arteries, lungs, pulmonary veins, LA, left AV valve, LV, aortic valve, aorta, body

layers of the pericardium

superficial tough fibrous layer

deep serous- visceral, parietal

layers of the heart from superficial to deep

epicardium, myocardium, endocardium

what attaches the AV valves to the walls of the ventricles

the tendinous cords

what do the tendinous cords attach to in order to prevent inversion of the AV valves

papillary muscles

what is the function of the auricles

increase capacity for blood

what does the coronary sinus divide

the atria and ventricles superficially

trace the conduction system through the heart

sinuatrial node

interatrial bundle and internodal pathways

atrioventricular node

atrioventricular bundle and bundle branches

subendocardial branches

what is the gateway to the ventricles in the hearts conduction system

the atrioventricular node

what branch off the aorta

the left and right coronary arteries

the circumflex branch supplies

the LA and posterior left ventriclet

the posterior interventricular branch supplies

the posterior ventricle walls and interventricular septum

the right marginal branch supplies

the lateral right atrium and ventricle

the left marginal branch supplies

the left lateral ventricle

the anterior interventricular branch supplues

the anterior ventricles walls and interventricular septum

the posterior veins of the left ventricle drains

posterior veins of left ventricle

the small cardiac vein drains

posterior right atrium and ventricle

the anterior interventricular vein drains

the anterior left and right ventricles and interventricular septum

the left and right marginal veins drain

the lateral portions of the left anf right ventricle

the middle cardiac vein drains

the posterior left and right ventricles
