The lungs of a corpse are seen from the middle: Both pulmonary blood arteries are found anterior to the bronchus, which means they are connected. Comparatively speaking, the pulmonary artery is superior to the pulmonary vein in that it has more robust and thicker walls than the latter.

Which vessel is the most posterior vessel arising from the arch of the aorta?
Approximately 65 percent of instances with right aortic arch with retroesophageal left subclavian artery have this configuration. The left subclavian is the most posterior artery on the arch and crosses the midline by traveling posterior to the esophagus, resulting in a midline crossing.
What is the basic unit of pulmonary structure?
The alveoli are the functional units of the lungs, and they serve as the location of gaseous exchange between the two chambers.
What is the basic unit of pulmonary structure called quizlet?
The alveoli are the structural and functional units of the respiratory system.
Which muscles aid in inspiration as well as flex the neck?
The sternocleidomastoid (SCM) muscle is a strap-like muscle that is responsible for the rotation and flexion of the head and neck. It is supplied with nerve fibers via the accessory nerve. This muscle may function as an auxiliary muscle during forced breathing, aiding with inspiration. Rib cage elevation and outward displacement are caused by this condition.
What is pulmonary arch?
The pulmonary arteries are blood vessels that convey blood from the right side of the heart to the lungs and back again. The term “pulmonary” refers to something that has an effect on the lungs in medical language. The blood is responsible for transporting oxygen and other nutrients to your cells. Your heart is a muscular pump that circulates blood throughout your body, allowing it to function properly.
Which aortic arch gives branches supplying the lungs?
The descending aorta is responsible for the formation of nine pairs of posterior intercostal arteries, a pair of subcostal arteries, two bronchial arteries for the left lung, and a few tiny branches to the oesophageal sphincter.
What is superior to the lungs?
The diaphragm is a flat, dome-shaped muscle that is placed at the base of the lungs and the thoracic cavity. It is responsible for breathing. The superior area of the lung is referred to as the apex, whereas the inferior region is referred to as the base, which is located near the diaphragm. The ribs are bordered by the costal surface of the lung. The mediastinal surface is the part of the body that faces the midline.
Which lung is higher than the other?
The right lung is much bigger and weights significantly more than the left lung. Because the heart is tilted to the left, the left lung is smaller than the right lung, and the left lung contains an indentation termed the cardiac impression to allow for the heart’s movement.
Where is the upper lobe of the lung?
This lung is positioned in the right superior corner of the thoracic cavity, lateral to the trachea and the esophagus, and it is the upper lobe of the right lung. It is located above the horizontal and oblique fissures, which divide the upper lobe of the right lung from the middle and lower lobes of the right lung, respectively.
What is the most inferior portion of the spinal cord called?
The spinal cord narrows at its inferior end, where it tapers to a point known as the conus medullaris, which gives birth to a significant number of massive nerve fibers known as the cauda equina. The cauda equina is a nerve that runs from the conus medullaris to the coccyx and descends into the spinal canal.
Which chamber of the heart receives the pulmonary veins?
The right atrium is the entry point for blood, which then passes through the right ventricle. The right ventricle is responsible for pumping blood to the lungs, where it is oxygenated. The pulmonary veins, which enter the left atrium, return the oxygenated blood to the heart, where it is pumped out again.
Which structure attaches the diaphragm to the lumbar spine?
It is connected to the xiphoid process and costal margin on the anterior side, the 11th and 12th ribs on the side opposite the xiphoid process, and the lumbar vertebrae on the back side. The crura, or tendinous bands, that connect the vertebrae to the rest of the body are responsible for the posterior attachment.
What muscles side flex the neck?
The scalene muscles aid in the flexion and side bending of the neck and spine. Known as the deep cervical flexors, this muscle group is made up of two muscles that run along the front of the cervical spine: the longus capitus and the longus colli muscles. The deep cervical flexor muscles aid in the forward flexion of the neck as well as the stabilization of the cervical spine.
Which muscle is involved with rotating and flexing the neck quizlet?
Which neck muscles are responsible for neck flexion? The neck is flexed by the anterolateral neck muscles ( sternocleidomastoid; anterior, middle, and posterior scalenes).
Which of the following muscles is involved in neck flexion?
This is called neck flexion, and the anterior scalene is responsible for it. The sternocleidomastoid (it’s in everything! ), longus capitis, and longus colli are some of the additional muscles that are involved in this process. Scalenes are responsible for neck flexion.
