Blood is a circulating tissue composed of fluid plasma and cells (red blood cells, white blood cells, platelets). Medical terms related to blood often begin in hemo- or hemato- (BE: haemo- and haemato-) from the Greek word "haima" for "blood". The main function of blood is to supply nutrients (oxygen, glucose) and constitutional elements to tissues and to remove waste products (such as carbon dioxide and lactic acid). Blood also enables cells (leukocytes, abnormal tumor cells) and different su ...

All blood vessels follow the same histological makeup. The inner lining is the endothelium, followed by subendothelial connective tissue. Then follows a muscular layer of vascular smooth muscle, which is highly developed in arteries. Finally, there is a further layer of connective tissue termed the adventitia, which contains nerves that supply the muscular layer, as well as nutrient capillaries in the larger blood vessel. Capillaries consist of little more than a layer of endot ...

The blood vessels are part of the circulatory system and function to transport blood throughout the body. The most important types, arteries and veins, are so termed because they carry blood away from or towards the heart, respectively. Blood vessel - Types.

Arteries are muscular vessels that carry blood away from the heart to the tissues and organs of the body (The vessels which return blood to the heart are veins). The circulatory system is extremely important in sustaining life. Its proper functioning is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide, waste products, maintenance of optimum pH, and the mobility of the elements, proteins and cells, of the immune system. In First World countries the two leading causes of ...

To blush is to display a marked redness of one's face; the term is seldom applied except when the redness is construed as a result of embarrassment, shame, or modesty. Blushing is generally distinguished, despite a close physiological relation, from flushing, which is more intensive and extends over more of the body, and seldom has a mental source. If redness persists for abnormal amounts of time after blushing, then it may be considered an early sign of rosacea. A medical condition known as Idiopathic craniofacial erythema exists, in which the sufferer ...

The coronary circulation consists of the blood vessels that supply blood to, and remove blood from, the heart. The vessels that supply blood high in oxygen to the heart are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart are known as cardiac veins. The coronary arteries that run on the surface of the heart are called epicardial coronary arteries. These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart mu ...

It plays a major role in metabolism and has a number of functions in the body including drug detoxification, glycogen storage, and plasma protein synthesis. It also produces bile, which is important for digestion. Medical terms related to the liver often start in hepato- or hepatic from the Greek word for liver, hepar. Liver - Anatomy.

In anatomy, the arm is the upper limb of a bipedal mammal, specifically the segment between the shoulder and the elbow. Arm can also refer to any analogous structure, such as one of the paired forelimbs of a quadruped, or any muscular hydrostat similar to a tentacle, as seen on some cephalopods, such as octopuses. The term arm also refers to the entire upper limb in an organism. Anatomically, the segment between the elbow and wrist is properly called the forearm. In primates the arms are richly adapted for ...

The cerebellum (Latin: "little brain") is a region of the brain that plays an important role in the integration of sensory perception and motor output. Many neural pathways link the cerebellum with the motor cortex—which sends information to the muscles causing them to move—and the spinocerebellar tract—which provides feedback on the position of the body in space (proprioception). The cerebellum integrates these two functions, using the constant feedback on body position to fine-tune motor movements. Because of this 'upda ...

Vascular is an adjective for the word vessel and refers to tube-like structures. In zoology, more specifically anatomy and physiology, "vascular" means "related to blood vessels", which are part of the Circulatory system. An organ or tissue that is vascularized is heavily endowed with blood vessels and thus richly supplied with blood. In botany, plants with a dedicated transport system for water and nutrients are called vascular plants. Vascular plants include ferns, conifers and flowering plants. A vascular bundle is part of such a transport system. ...

The spleen is a ductless, vertebrate gland that is not necessary for life but is closely associated with the circulatory system, where it functions in the destruction of old red blood cells and removal of other debris from the bloodstream, and also in holding a reservoir of blood. It is regarded as one of the centres of activity of the reticuloendothelial system. Until recently, the purpose of the spleen was not known. It is increasingly recognised that its absence predisposes to certain infections. Spleen - Anatomy. ...

In human anatomy, the axillary vein is a large blood vessel that conveys blood from the lateral aspect of the thorax, axilla (armpit) and upper limb toward the heart. Its origin is at the lower margin of the teres major muscle and a continuation of the brachial vein. Its tributaries include the basilic vein and cephalic vein, which are both superficial veins. It terminates at the lateral margin of the first rib, at which it becomes the subclavian vein. It is accompanied along its cour ...

In anatomy, the atrium (plural: atria) is the blood collection chamber of a heart. It has a thin-walled structure that allows blood to return to the heart. There is at least one atrium in an animal with a closed circulatory system. In fish, the circulatory system is very simple: a two-chambered heart including one atrium and one ventricle. In vertebrate groups that evolved later, the circulatory system is much more complicated. Their circulatory systems are divided into two types: a three-chambered heart, with two atria ...

In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, axilla (armpit) and upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery. It has several smaller branches. In order, when traveling from the heart, they are: Superior thoracic artery, Thoracoacromial artery, Lateral thoracic artery, Subscapular artery, Anterior circumflex humeral artery an ...

In human anatomy, the basilar artery is one of the arteries that supplies the brain with oxygen-rich blood. It arises from the confluence of the two vertebral arteries at the level of the medulla oblongata. It ascends in the central gutter (sulcus basilaris) inferior to the pons and divides into the two posterior cerebral arteries. From the basilar artery arise branches for the supply of the cerebellum (largely via the anterior inferior cerebellar artery), as ...
