Nov 21, 2023 · Blood supply. The lungs have dual, parallel blood supply referred to as pulmonary and systemic circuits. The pulmonary circuit arises from the heart and brings deoxygenated blood to the lung for gas exchange. This circuit also takes oxygenated blood back to the heart to be redistributed to the rest of the body.

Abstract. Diffuse pulmonary ossification (DPO) is a rare condition of DLD (diffuse lung disease) characterized by the presence of metaplastic ectopic bone in the lungs and is less frequent in patients without a clear background of lung diseases. DPO is characterized by very small calcific nodules, often with bone mature located in both lungs ...

The lung roots, or hila (singular – hilum), are complicated anatomical structures containing the pulmonary vessels and the major bronchi, arranged asymmetrically. Although the hilar lymph nodes are not visible on a normal chest X-ray, they are of particular importance clinically. Often, hilar enlargement is due to enlargement of these nodes.The two lungs and their pleural sacs are situated in the thoracic cavity (figs. 22-1 and 22-2 ). The pleura is a thin, glistening, slippery serous membrane, inflammation of which is called pleurisy. The pleura lines the thoracic wall and diaphragm, where it is known as the parietal pleura.

Bone Structure. Compact bone is the hard material that makes up the shaft of long bones and the outside surfaces of other bones. Compact bone consists of cylindrical units called osteons. Each osteon contains concentric lamellae (layers) of hard, calcified matrix with osteocytes (bone cells) lodged in lacunae (spaces) between the lamellae.

The base of the lungs is concave to follow the contour of the diaphragm. The left lung is slightly smaller than the right lung because 2/3 of the heart is located on the left side of the body. The left lung contains the cardiac notch, an indentation in the lung that surrounds the apex of the heart.Lungs are the primary respiratory organs found in humans and most of the animals. Humans have two lungs - a right lung and a left lung. Read this article to learn in detail about the anatomy of lungs. ... The root of the lung is a structure that emerges from the hilum of the lung. The bronchus, lymphatic vessels, nerves, pulmonary artery and ...The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.The sternum is the elongated bony structure that anchors the anterior thoracic cage. It consists of three parts: the manubrium, body, and xiphoid process. The manubrium is the wider, superior portion of the sternum. The top of the manubrium has a shallow, U-shaped border called the jugular (suprasternal) notch.

This is in line with the sternal angle, but the carina may raise or descend up to two ...Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. Compact Bone. Compact bone is the denser, stronger of the two types of bone tissue (Figure 6.12). It can be found under the periosteum and in the diaphyses of long bones, where it provides ...To help adjust your breathing to changing needs, your body has sensors that send signals to the breathing centers in the brain. Sensors in the airways detect lung irritants. The sensors can trigger sneezing or coughing. In people who have asthma, the sensors may cause the muscles around the airways in the lungs to contract.The lungs are pyramid-shaped, paired organs that are connected to the trachea by the right and left bronchi; on the inferior surface, the lungs are bordered by the diaphragm. The diaphragm is the flat, dome-shaped muscle located at the base of the lungs and thoracic cavity.Airways can be divided into upper and lower. The upper and most of the lower airways are involved in the humidification of air during breathing and its conduction to the alveoli where oxygen exchange with the blood takes place. 3. Both the upper and lower airways create dead space.
