The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart. The pulmonary veins are part of the pulmonary circulation.
In human anatomy, the radial artery is the main artery of the lateral aspect of the forearm.
The superior mesenteric vein is a blood vessel that drains blood from the small intestine. Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the hepatic portal vein. The superior mesenteric vein lies to the right of the similarly named artery, the superior mesenteric artery, which originates from the abdominal aorta.
The splenic vein is a blood vessel that drains blood from the spleen, the stomach fundus and part of the pancreas. It is part of the hepatic portal system.
In human anatomy, the inferior mesenteric vein (IMV) is a blood vessel that drains blood from the large intestine. It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).
The coronary sinus is a collection of veins joined together to form a large vessel that collects blood from the heart muscle (myocardium). It delivers less-oxygenated blood to the right atrium, as do the superior and inferior venae cavae. It is present in all mammals, including humans.
The superior ophthalmic vein is a vein of the orbit around the eye. It begins from the angular vein and the supraorbital vein, and passes through the superior orbital fissure to drain into the cavernous sinus. It drains the ethmoidal veins, the lacrimal vein, the central retinal vein, some vorticose veins, and veins from two rectus muscles. It can be a path for the spread of infection from the danger triangle of the face to the cavernous sinus and the pterygoid plexus. It may also be affected by an arteriovenous fistula of the cavernous sinus, treated with embolization.
The inferior ophthalmic vein is a vein of the orbit around the eye. It receives veins from many structures. It divides into two branches, one of which ends in the pterygoid plexus through the inferior orbital fissure, and the other which ends in the cavernous sinus through the superior orbital fissure. It drains blood from the inferior rectus muscle, the inferior oblique muscle, the lateral rectus muscle, the inferior conjunctiva, and the lacrimal sac. It can be affected in periorbital cellulitis.
The supraorbital vein is a vein of the forehead. It communicates with the frontal branch of the superficial temporal vein. It passes through the supraorbital notch, and merges with the angular vein to form the superior ophthalmic vein. The supraorbital vein helps to drain blood from the forehead, eyebrow, and upper eyelid.
The posterior auricular vein is a vein of the head. It begins from a plexus with the occipital vein and the superficial temporal vein, descends behind the auricle, and drains into the external jugular vein.
The cerebral veins are divisible into external and internal groups according to the outer surfaces or the inner parts of the hemispheres they drain into.
The cerebellar veins are veins which drain the cerebellum. They consist of the superior cerebellar veins and the inferior cerebellar veins. The superior cerebellar veins drain to the straight sinus and the internal cerebral veins. The inferior cerebellar veins drain to the transverse sinus, the superior petrosal sinus, and the occipital sinus.
The dorsal venous network of the hand is a network of veins within the superficial fascia on the dorsum (backside) of hand. It is formed by the dorsal metacarpal veins, and gives rise to veins such as the cephalic vein and the basilic vein.
The vorticose veins, referred to clinically as the vortex veins, drain the ocular choroid. The number of vortex veins is known to vary from 4 to 8 with about 65% of the normal population having 4 or 5. In most cases, there is at least one vortex vein in each quadrant. Typically, the entrances to the vortex veins in the outer layer of the choroid can be observed funduscopically and provide an important clinical landmarks identifying the ocular equator. However, the veins run posteriorly in the sclera exiting the eye well posterior to the equator.
The pampiniform plexus is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
The left gastric vein is a vein that derives from tributaries draining the lesser curvature of the stomach.
The esophageal veins drain blood from the esophagus to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck. It also drains, although with less significance, to the hemiazygos vein, posterior intercostal vein and bronchial veins.
The deep palmar arch is accompanied by a pair of venae comitantes which constitute the deep palmar venous arch. It receives the veins corresponding to the branches of the arterial arch: the palmar metacarpal veins.
The anterior auricular veins are veins which drain the anterior aspect of the external ear. The veins drains to the superficial temporal vein.
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking.
