Lungs
lines the pulmonary cavities, adhearing to the thoracic wall
What is parietal pleura
Located on the posterior aspect, formed mainly by the L atrium around T6-T9
What is the base of the heart
Produces either stenoisis or insufficiency. Both result in an increased workload for the heart.
WHat is Valvular Heart Disease
Carry well oxygenated blood from the lungs to the Left Atrium
What are the pulmonary veins ( 4 total right and left superior and inferior)
The pacemaker of the heart
SA node
Root of the lung is composed of structures entering and emerging from the lung at this location
Hilum
Receives deoxygenated blood from the IVC/SVC
Right Atrium
Entry of air into the pleural cavity results from a penetrating wound of the parietal pleura. May also occur as a result of leakage from the lung through an opening in the visceral pleura
WHat is pneumothorax
located in the submucosa of the bronchi, largey drains structures that form the root of the lung
What is the deep lymphatic
Innervated by the cardiac plexus
What is the AV node
Has 3 lobes- superior, middle, inferior
Right lung
Passage way fro deoxygenated blood to get to the lungs
Pulmonary arteries
Inflammation of the pericardium, usually causes chest pain. makes surfaces with pericardium rough which results in friction
WHt is pericarditis
Main vein of the heart. has 3 veins that dump into it:
Great cardiac: from the L
Middle Cardiac: from the R
Small Cardiac: from the R
slows the hart rates, reduces the force of the contraction and constricts the coronary arteries
what is the parasympathetic- vagus nerve
The names of the levels of bronchiols
What are: Principal (one to each lung)
lobal ( 2 to L lung, 3 to R lung to supply each lobe)
Tertiary: branching from lobual branch each segment is pyramidal ( 20-25 generations beyond that)
This structure is stronger than the other side due to the need to work harder
Left ventricle
no sound made during inhalation/exhalation however, inflammation of the pleurae makes the lungs surfaces rough. Pleural rub may be heard
What is pleuritis
Artery branches off into (2) supplying arteries- anterior interventricular and circumflex
what is the left coronary artery
Inituates and regulates the impulses for contraction, giving an impulse about 70 times per minute
what is the SA node
Visceral pleura
Only valve to be heard on the right side using a stethescpoe around intercostal space
Aortic
Suddon occlusion of a major artery by an embolus, the region of myocardium supplied by the occluding vessel becomes infarcted.
WHat is myocardial infarction
Originates in the L aortic sinus, runs in AV sulcus to give of branches to other arteries, distributes blood to most of LA and LV, IV septum, AV bundles and may supply the AV node
What is the left coronary artery
Distributes the signal to the ventricles through a bundle
what is the AV node
