submucous plexus An autonomic nerve plexus extending from the cardiac plexus into the lungs along the right and left pulmonary arteries. Parasympathetic axons come from the vagus nerves, and sympathetic axons from the sympathetic trunk. Axons from the pulmonary plexus follow the bronchi and the bronchial vessels and provide the autonomic innervation inside the lungs.

The Cervical Plexus The Cervical Plexus. The cervical plexus is a network of nerve fibres that supplies innervation to some of the structures in the neck and trunk. It is located in the posterior triangle of the neck, halfway up the sternocleidomastoid muscle, and within the prevertebral layer of cervical fascia. The plexus is formed by the anterior rami (divisions) of cervical spinal nerves C1-C4.

Pulmonary circulation Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The term pulmonary circulation is readily paired and contrasted with the systemic circulation.

Heart Pulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart again. Deoxygenated blood leaves the heart, goes to the lungs, and then re-enters the heart; Deoxygenated blood leaves through the right ventricle through the pulmonary artery.From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.Blood is then pumped from the right ventricle through the pulmonary valve and into the pulmonary trunk of the pulmonary artery.he oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. This blood then enters the left atrium, which pumps it through the bicuspid valve, also called the mitral or left atrioventricular valve, into the left ventricle.

Pulmonary edema Pulmonary edema is an accumulation of fluid within the parenchyma and air spaces of the lungs. Classically it is cardiogenic (left ventricular) but fluid may also accumulate due to damage to the lung. This damage may be direct injury or injury mediated by high pressures within the pulmonary circulation.

Heart Anatomy Pulmonary hypertension is high blood pressure in the arteries of the lungs. It makes the right side of the heart work harder than normal. The right side of the heart pumps blood through the lungs, where it picks up oxygen. Blood returns to the left side of the heart, where it is pumped to the rest of the body.

Pulmonary circulation The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle of the heart, to the lungs, and returns oxygenated blood to the left atrium and ventricle of the heart. The term pulmonary circulation is readily paired and contrasted with the systemic circulation. The vessels of the pulmonary circulation are the pulmonary arteries and the pulmonary veins. A separate system known as the bronchial circulation supplies oxygenated blood to the tissue of the larger airways of the lung.

The Lungs and Respiration The pulmonary arteries form smaller blood vessels called arterioles which direct blood flow to the capillaries surrounding lung alveoli. The alveoli in the lungs are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries. Carbon dioxide also diffuses from the blood in the capillaries to the alveoli air sacs. The now oxygen rich blood is returned to the heart via the pulmonary veins. Carbon dioxide is expelled from the lungs by exhalation.

MADMAN BIOLOGY The pulmonary veins are the only veins in the body that carry OXYGENATED blood (from the lungs to the left atrium), and the pulmonary arteries are the only arteries in the bod … y that carry DEOXYGENATED blood (from the right ventricle to the lungs).hat is different about them is that the pulmonary artery carries deoxygenated blood (blood without oxygen) as … supposed to other arteries, which carry oxygenated blood. And the pulmonary vein carries oxygenated blood unlike other veins, which carry deoxygenated blood.

How do we breathe? (Lungs and Pleura) The lungs are surrounded by a double membrane called pleura. This membrane has two layers, a parietal pleura and a visceral pleura.The parietal pleura is attached to the chest wall and the visceral pleura covers the surface of the lungs.Between these layers of pleura is a potential space i.e. a space that doesn’t exist but it could exist if something goes wrong.his membrane has two layers, a parietal pleura and a visceral pleura. The parietal pleura is attached to the chest wall and the visceral pleura covers the surface of the lungs.

Pleural Thickening: How it affects the Lung Many of the organs and cavities throughout the body have a lining or membrane surrounding the tissue. The membrane surrounding the lungs is known as the pleura and its job is to support and protect the lung tissue. Pleural thickening of this lining leads to a problem in the functionality of the protective membrane.ven though pleural thickening affects only the lining of the lungs, it can lead to more severe problems. The signs and symptoms associated with the thickening can be from damage to the lining itself or any number of other complications which may have arisen.

The Lungs Pleura of the Lungs. Each lung is enclosed within a cavity that is surrounded by the pleura. The pleura (plural = pleurae) is a serous membrane that surrounds the lung. The right and left pleurae, which enclose the right and left lungs, respectively, are separated by the mediastinum.he major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body.

Choroid plexus The choroid plexus (CP) (from Greek khorion membrane enclosing the fetus, afterbirth; plexus: Mod.L., lit. braid, network) is a plexus of cells that produces the cerebrospinal fluid in the ventricles of the brain.here is also choroid plexus in the fourth ventricle, in the section closest to the bottom half of the cerebellum. The choroid plexus consists of many capillaries, separated from the ventricles by choroid epithelial cells. Fluid filters through these cells from blood to become cerebrospinal fluid.

Pulmonary Capillaries Summary Information: Pulmonary Capillaries. Pulmonary Capillaries: The pulmonary capillaries are tiny blood vessels that surround the alveoli of the lungs. The pulmonary capillaries receive deoxygenated blood from the small branches (arterioles) of the right pulmonary artery and left pulmonary artery and allow for the exchange of blood gasses with the alveoli. In this process, carbon dioxide is released from the blood and fresh oxygen is picked up.
