Thorax/heart Flashcards
The aorta arises from the
Ventricle left
The strongest thickest muscle of the heart is located in the
Left ventricle
The pulmonary veins bring blood to the
Left atrium
The first vessel to branch off the aortic arch is the
Brachiocephalic trunk
What is the chief muscle of respiration
Diaphragm
The superior vena cava is formed by the junction of the
Brachiocephalic vein’s
What makes up the apex of the heart
Left ventricle
Collateral circulation between the inferior Venna cava and the superior Venna cava is supplied by
Azygos veins
What is not considered a Medistinal structure
The Lungs
What is located between the upper thoracic vertebra and the trachea
Esophagus
The heart is lined by serious membrane called
The pericardium
The middle layer of the heart wall
Myocardium
The diaphragm is attached to the lumbar spine via two tendinous structures termed
Crura
A hormone which is responsible for the development and mature ration of lymphocytes produced by the thymus gland
Thymosine
The 4 pulmonary veins bring oxygenated blood to the
left atrium
Another name for the medial angle of the lung is
Cardiophrenic sulcus
What artery supplies blood to the right atrium and right ventricle of the heart
The right coronary artery
The aperture that allows the passage of nerves vessels and viscera from the neck into the thoracic cavity is known as
Thoracic inlet
Chords of connective tissue
Cooper’s ligaments
Elevates the ribs
Levators costarum
Collateral circulation
Azygos vein
Opening on medial surface of the Lungs
Hilum
Covers lung surface
Visceral pleura
Semi lunar valve
Aortic valve
Carries deoxygenated blood to the lungs
Pulmonary arteries
Interior border of bony thorax
Sternum
Articulation between a rib cartilage and sternum
Sternocostal
A bony thorax articulates between the typical of the rib and the transverse process of the thoracic vertebrae
Costotransverse joint
How many lobes are in the right and left lung
3 right, 2 left
The narrow upper portion of the lung
Apex
The left side of the tracheobronchial tree there are how many secondary bronchi
2
The portions of the tracheobronchial tree that enters each lobe of the lung are termed
Secondary bronchi
The fissures are lined by
Visceral pleura
The heart and great vessels are located in the compartment of the mediastinum
The middle portion
The posterior border of the anterior portion of the inferior compartment of the mediastinum
Pericardium
The main Lymphatic vessel is the
Thoracic duct
Lymph nodes are easily recognizable on sectional images only when they are
Abnormal
The tough outer covering of the heart that is attached to the diaphragm
Fibrous pericardium
The layer of the heart wall that is in contact with the pericardium
Epicardium
Which chamber of the heart receives oxygenated blood from the pulmonary veins
The left atrium
The great vessel drains the head neck and upper limbs
Superior vena cava
The vein that provides collateral circulation for the thorax
Azygos vein
The main vein of the heart
Coronary sinus
How does the pectoralis major muscle of the interior thoracic wall assist with respiration
It helps expand thoraciccavity during inspiration
The diaphragm originates at the
Central tendon
Which opening in the diaphragm allows the passage of the Vagus nerve and esophagus
Esophageal hiatus
The suspensory or Cooper’s ligaments of the breast are part of what tissue of the breast
Mammory
Which layer of the pleura moves with respiration
Parietal pleura
The Superior border of the Superior compartment of the mediastinum
Thoracic inlet
The thymus gland is located in the anterior portion of the
Mediastinum
The lymph drainage for the body below the level of the diaphragm is provided by
Thoracic duct
The portion of the pericardium that has two layers that form the pericardial space
Serous pericardium
The inner endothelial layer of the heart
Endocardium
What chamber of the heart pumps blood through the aortic semi lunar valve
Left ventricle
Which great vessel is formed by the Anistomosis of the right and left common iliac vein’s
Inferior vena cava
The primary muscles of respiration act to elevate the ribs during inspiration
External intercostals
How many openings are in the diaphragm to allow for vessels organs into the abdminal cavities
Three
