How the pulmonary circulation works The pulmonary circulation, together with the great or systemic circulation, forms the human circulatory system. It begins in the right heart: the blood, which is low in oxygen and loaded with carbon dioxide, coming from the body is pumped via the right atrium and the right ventricle into the truncus … Pulmonary Circulation: Structure and Function
The ascending lumbar vein is an ascending blood vessel that runs alongside the spine. In the right half of the body, it flows into the azygos vein, while on the left it flows into the hemiazygos vein. The ascending lumbar vein may provide a bypass route in cases of inferior vena cava embolism. What is … Ascending Lumbar Vein: Structure, Function & Diseases
Definition – What is the Foramen ovale? The heart consists of two atria and two chambers, which are normally separated from each other. However, the Foramen ovale represents an opening, which causes blood to pass from the right atrium to the left atrium in the fetus. Normally, blood would pass from the right atrium into … The Foramen ovale of the heart
What role does the Foramen ovale play in the baby After birth and as a result of a baby’s first breaths, there is a change in pressure within the lungs and heart. The blood no longer passes through the Foramen ovale, but passes through the natural lung and body circulation. The Foramen ovale is therefore … What role does the Foramen ovale play in the baby | The Foramen ovale of the heart
Paradoxical embolism Paradoxical embolism, also known as “crossed embolism”, is the transfer of a blood clot (embolus) from the venous to the arterial part of the bloodstream. The reason for this is a defect in the area of the heart septum, usually caused by an unclosed Foramen ovale. When the foramen ovale is closed, the … Paradoxical embolism | The Foramen ovale of the heart
Does a Foramen ovale require blood thinning? In the case of an open Foramen ovale it is not necessarily necessary to use blood-thinning medication. Thrombi can pass through the Foramen ovale, which is why the Foramen ovale indirectly increases the probability of a possible stroke in the brain or further embolisms within the large circulation. … Does a Foramen ovale require blood thinning? | The Foramen ovale of the heart
The pulmonary circulation, also called the small circulation, is part of the human cardiovascular system. It regulates the transport of blood between the heart and the lungs and is used for gas exchange, i.e., the absorption of oxygen into the blood and the release of carbon dioxide into the air we breathe. What is the … Pulmonary Circulation: Function, Purpose & Diseases
Definition As part of the “small” or pulmonary circulation, the right ventricle is located downstream of the right atrium (atrium dextrum) and pumps the oxygen-depleted blood into the pulmonary vessels, where it is again saturated with oxygen and then enters the body’s circulation via the left heart. Anatomy The heart lies rotated around its longitudinal … Right ventricle
Histology wall layering The wall layers are the same in all four heart interiors: The innermost layer is the endocardium, consisting of a single-layer epithelium, which is supported by the connective tissue lamina propria. The muscle layer (myocardium) is connected to the outside of this. The outermost layer is the epicardium. Blood supply The heart … Histology wall layering | Right ventricle
Diseases of the blood circulation Especially older people often suffer from circulatory disorders. One of the most well-known diseases is arteriosclerosis. This is a change in the innermost vascular layer in the small arteries. Cholesterol and calcium deposits cause the vessel to become increasingly narrow and prevent sufficient blood flow to the structures it supplies. … Diseases of the blood circulation | The human blood circulation
Definition The blood circulation consists of the heart and the blood vessels. The heart serves as a pump to pump the blood in the vessels through the body. For this purpose, the human body has a vascular system that branches out from the large vessels that originate directly from the heart to reach every part … The human blood circulation
Classification of the blood circulation The blood circulation is divided into a large circulation, the body circulation, and a small circulation, the lung circulation. In order to understand these two circuits, one must first understand the structure of the heart. The heart consists of two ventricles (ventricles) and two atria (atria). The left atrium and … Classification of the blood circulation | The human blood circulation
