The adrenal gland is divided functionally and topographically into the adrenal cortex (cortex glandulae suprarenalis) and the adrenal medulla (medulla glandulae suprarenalis). The adrenal medulla forms the smaller part of the adrenal gland. Adrenaline and noradrenaline are produced in the medulla of the adrenal gland. What is the adrenal medulla? The adrenal gland is a … Adrenal Medulla: Structure, Function & Diseases
The lingual artery is responsible for supplying blood to the tongue. It passes between the lower muscles of the tongue in a strongly serpentine manner. Colloquially, it is called the lingual artery. The lingual artery comes from the external aorta as a second main trunk next to the facial artery. Along its path, the sublingual … Lingual Artery: Structure, Function & Diseases
The systemic circulation is also called the great circulation. It carries blood through the majority of the body. The other major circulation of the body is the pulmonary circulation, which carries blood to and from the lungs. What is the circulatory system? The main function of the systemic circulation is to supply oxygenated blood to … Body Circulation: Function, Task & Diseases
Vascularization is the connection of an organ to the blood system and thus can also correspond to a new formation of smaller vessels. In the case of pathologic neovascularization, such as the systemic connection of a tumor, it is also referred to as neovascularization. In medical practice, vascularization plays a role mainly therapeutically. What is … Vascularization: Function, Tasks, Role & Diseases
Blood flow is the movement of blood in the body’s circulatory system. Blood flow is influenced by various conditions in the body. What is blood flow? Blood flow is understood as the movement of blood in the body’s circulatory system. Blood is a fluid of the body that consists of special blood cells and liquid … Blood Flow: Function, Tasks, Role & Diseases
The truncus coeliacus is an unpaired arterial trunk that arises anteriorly toward the abdomen (ventrally) from the abdominal portion of the aorta still above the paired renal arteries. It branches after a few centimeters into three other arteries that supply arterial, oxygenated blood to various abdominal organs as well as part of the mesentery. Because … Truncus Coeliacus: Structure, Function & Diseases
The baroreceptor reflex is initiated by baroreceptors (also called pressoreceptors) in the walls of blood vessels and corresponds to an automatic response of the circulatory center to sudden changes in blood pressure. In case of suddenly lowered blood pressure due to blood loss, the reflex ensures blood supply to vital organs with centralization of the … Baroreceptor Reflex: Function, Tasks, Role & Diseases
Shock is a health-threatening process in the human body. This is capable of being life-threatening and can occur in various forms. The basis is the undersupply of the organism with oxygen due to differentiated causes. What is shock? Shock is a health-threatening process in the human body. Shock causes the circulation of blood in small … Shock: Function, Tasks, Role & Diseases
The abdominal aorta is the descending portion of the large body artery below the thoracic aorta. The abdominal aorta begins at the level of the diaphragmatic hernia and extends to branch into the two major iliac arteries at the level of the fourth lumbar vertebra. The two larger renal arteries and a number of smaller … Abdominal Aorta: Structure, Function & Diseases
Dihydralazine is an antihypertensive agent used to treat arterial hypertension. The exact molecular mode of action is not known. A major use is for blood pressure regulation in severe preeclampsia. What is dihydralazine? Dihydralazine is a blood pressure-lowering agent used for the treatment of arterial hypertension. Dihydralazine is a pharmacologic agent that has applications against … Dihydralazine: Effects, Uses & Risks
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
The greater splanchnic nerve is a sympathetic nerve of the autonomic nervous system that supplies the blood vessels, the building organs, and the adrenal medulla. The adrenal medulla is stimulated to release adrenaline and noradrenaline via the sympathetic fibers of the nerve. The result is a stress response that plays a role in acute shock, … Greater Splanchnic Nerve: Structure, Function & Diseases
