Highest intercostal artery
Each of the following statements abut a pleural cavity is correct EXCEPT:
It is a large cavity when the lung is deflated
air moves freely in and out of it during respiration
It is a potential space between the layers of the pleura
It normally contains a capillary layer of fluid

Which of the following is an INCORRECT completion? The visceral pleura is -
Supplied by the bronchial arteries
Drained by veins which open into the pulmonary veins
Supplied by autonomic nerves which accompany the bronchial vessels
Very sensitive to pain, particularly near the root of the lung
Drained by lymphatic vessels that enter lymph nodes in the hilum of the lung
Correct statements about the bronchial arteries include each of the following EXCEPT:
they supply the substance of the lung tissue
They are small and pass along the posterior aspects of the bronchi
They supply the bronchi as far distally as the respiratory bronchioles
The 2 left bronchial arteries arise form the thoracic aorta
The single right bronchial artery usually arises form the aorta
One completion is INACCURATE, which one is it? The heart is
A hollow muscular organ
normally slightly larger than a clenched fist
Placed obliquely in the thorax
Situated so that most of its anterior surface consists of the left ventricle
Visible in routine radiographs of the chest and stands out in contrast to the clearer areas occupied by the air filled lungs
Encircles most of the superior part of the heart
Apex of the heart
right border of the heart
Base of the heart
Coronary groove (sulcus)
Apex of the lung
..................... is Formed by the right atrium
Apex of the heart
Right border of the heart
Base of the heart
Coronary groove (sulcus)
