Overall, perfusion increases more than ventilation at the base of the lung, resulting in lower V/Q ratios in the base of the lung compared to the apex. In a healthy individual, the V/Q ratio is 1 at the middle of the lung, with a minimal spread of V/Q ratios from 0.3 to 2.1 from base to apex.
Lung Anatomy & Function Lung Nodule, Lung Disease and Lung Infection
The apex of the lung is the superior region, whereas the base is the opposite region near the diaphragm. The costal surface of the lung borders the ribs. The mediastinal surface faces the midline. Figure 1. Gross Anatomy of the Lungs. Each lung is composed of smaller units called lobes. Fissures separate these lobes from each other.

Summary. The main function of the respiratory system is gas exchange (O 2 and CO 2 ). Ventilation is the movement of air through the respiratory tract into (inspiration) and out of (expiration) the respiratory zone ( lungs ). The. physiologic dead space. is the volume of inspired air that does not participate in gas exchange.

Structure Anatomy. The lungs are located in the chest on either side of the heart in the rib cage.They are conical in shape with a narrow rounded apex at the top, and a broad concave base that rests on the convex surface of the diaphragm. The apex of the lung extends into the root of the neck, reaching shortly above the level of the sternal end of the first rib.

Anatomically, the lung has an apex, three borders, and three surfaces. The apex lies above the first rib. The three borders include the anterior, posterior, and inferior borders. The anterior border of the lung corresponds to the pleural reflection, and it creates a cardiac notch in the left lung. The cardiac notch is a concavity in the lung.

By A. Mendelson, MD May 4, 2022. Please read the disclaimer. Lung apex is the term used to describe the very top of the lungs. This description can be found on many different types of reports from X-rays to MRI. Lung apex is a tough area to evaluate on x-ray because of all the overlapping structures, like ribs, clavicle and blood vessels.
Apex of the lung Pocket Anatomy
The lung apex is the very top of the lung. The lung apex is in the upper lobes of the lungs. A characteristic set of abnormalities is found here, although many common conditions like pneumonia and cancer can also be found. This area can be hard to evaluate well on X-rays because of overlying bones like the clavicle, ribs and blood vessels.

Apex of lung. The apex is a rounded tip of the superior end of each lung that projects at the level of the spinous process of the seventh cervical vertebrae (C7). It is situated above the superior thoracic aperture (thoracic inlet) posterior to the scalene muscles. More precisely, the apex is located in the root of the neck, approximately 1 - 2.

The apex of each lung is anteriorly related to the anterior ramus of spinal nerve T1, the stellate (cervicothoracic sympathetic) ganglion, and the superior intercostal artery found on the same side. The medial surface of the apex of the left lung is laterally related to the left brachiocephalic vein and left subclavian artery.

The apex of the lung is located where the upper lobe begins, while the base of the lungs is by the diaphragm, where the costal surface borders our ribcage. Each lung is divided into separate units known as lobes, which are separated by fissures. The right lung is split into three lobes: the superior, middle, and inferior.
8.2 The Lungs Fundamentals of Anatomy and Physiology
Each lung has a base resting on the diaphragm and an apex extending superiorly to a point approximately 2.5 cm superior to the clavicle. It also has a medial surface and with three borders- anterior, posterior and inferior. The broad coastal surface of the lungs is pressed against the rib cage, while the smaller mediastinal surface faces medially.

Lungs are a pair of respiratory organs situated in a thoracic cavity. Right and left lung are separated by the mediastinum. Texture -- Spongy. Color - Young - brown. Adults -- mottled black due to deposition of carbon particles. Weight-. Right lung - 600 gms. Left lung - 550 gms.

Anatomy. The right upper lobe of the lung is located in the right superior corner of the thoracic cavity lateral to the trachea and esophagus. It is superior to the horizontal and oblique fissures, which separates the upper lobe from the middle and lower lobes of the right lung.mycontentbreak. The right upper lobe begins at the apex, the.
