An erectile tissue is a vascular plexus that can fill with blood. In the body, there are different erectile tissues that perform different functions and tasks. What is a corpus cavernosum? The medical term for erectile tissue is corpus cavernosus. It is a plexus of blood vessels. The vascular plexus can be arterial or venous. … Corpus Cavernosum: Structure, Function & Diseases
Fibrinolysis is characterized by the dissolution of fibrin by the enzyme plasmin. It is subject to complicated regulatory mechanisms in the organism and is in balance with hemostasis (blood clotting). Disturbance of this balance can lead to severe bleeding or thrombosis as well as embolism. What is fibrinolysis? The function of fibrinolysis is to limit … Fibrinolysis: Function, Role & Diseases
The pulmonary artery is an artery that carries deoxygenated blood from the heart to one of the two lungs. The two arteriae pulmonales are branches of the truncus pulmonalis, the pulmonary trunk that connects to the right ventricle of the heart. Sensuously, the two pulmonary arteries are referred to as the sinistra pulmonary artery for … Pulmonary Artery: Structure, Function & Diseases
The two heart valves that respectively connect the left atrium to the left ventricle and the right atrium to the right ventricle are called leaflet valves for anatomical reasons. The two leaflet valves function according to the recoil principle and, together with the other two heart valves, which are so-called semilunar valves, ensure orderly blood … Sail Valve: Structure, Function & Diseases
Uptake, entrapment, and digestion of non-cellular particles in a cell specialized for this process is called phagocytosis. Particle entrapment occurs through the formation of cavities (phagosomes) that, after particle uptake, fuse with specialized vesicles called lysosomes. They contain the enzymes necessary for digestion or degradation of the trapped particles. What is phagocytosis? Phagocytosis is the … Phagocytosis: Function, Role & Diseases
In the anterior chamber of each eye lies the angle of the ventricle, where the cornea, iris, and eye chamber meet. The most important function of this structure is to regulate fluid in the eye, keeping intraocular pressure at a normal level. In diseases of the ventricular angle, the fluid-regulating function of the structure may … Ventricular Angle: Structure, Function & Diseases
Sclerotherapy is the technical term for the induced and targeted formation of thrombus or sclerus during treatment with subsequent remodeling of the connective tissue. The medical term goes back to the Greek word “skleros”, which is translated as “hard”. Sclerotherapy results in artificial obliteration (hardening) of the treated tissue and vessels. The hardening or sclerotherapy … Sclerotherapy: Treatment, Effect & Risks
Definition The epithelium is one of the four basic tissues of the body and is also called the covering tissue. Almost all body surfaces are covered by epithelium. These include both external surfaces, such as the skin, and the internal surfaces of hollow organs, such as the bladder. The epithelium is an extensive group of … Epithelium
Epithelium of the eye The stomach is internally lined by the gastric mucosa, the innermost layer of which forms a single-layered, highly prismatic epithelium. This means that the epithelial cells have an elongated shape. The individual cells are connected to each other by special connections, so-called tight junctions. The epithelium and the adjacent layers form … Epithelium of the eye | Epithelium
Epithelium of the skin The skin (epidermis) is separated from the outside by a multi-layered cornified squamous epithelium. This provides mechanical protection, prevents the penetration of bacteria and prevents the body from drying out. It is called squamous epithelium because the uppermost cell layer consists of flat cells. Since these cells die constantly, turn into … Epithelium of the skin | Epithelium
Carcinomas Carcinomas, i.e. malignant tumors, can also develop in epithelia. Here there are different types, which arise from different types of epithelium. They must be distinguished from the so-called adenomas, which are benign tumors of glands of the epithelium. Papillomas are also benign epithelial growths.A carcinoma can develop from squamous epithelium, then one speaks of … Carcinomas | Epithelium
The endothelium is a single-layer layer of flat cells that lines all vessels and thus represents an important barrier between intravascular and extravascular space (as the space inside and outside the blood vessels). Structure The endothelium forms the innermost cell layer of the intima, the inner layer of the three-layer wall structure of an artery. … Endothelium
