| BVP | blood vessel prosthesis; blood volume pulse; burst of ventricular pacing |
| LVH | large vessel hematocrit; left ventricular hypertrophy |
| efferent | Moving or carrying outward or away from a central part. Refers to vessels, nerves, etc. For example: blood vessels carrying blood away from the heart or nerves carrying signals from the brain. Compare: afferent. (09 Oct 1997) |

| efferent duct | One of 12 to 14 small seminal ducts leading from the testis to the head of the epididymis. Synonym: ductulus efferens testis, vas efferens, efferent duct. (05 Mar 2000) |
| efferent ductules of testis | One of 12 to 14 small seminal ducts leading from the testis to the head of the epididymis. Synonym: ductulus efferens testis, vas efferens, efferent duct. (05 Mar 2000) |
| efferent fibres | Those fibres conveying impulses to effector tissues (muscle: smooth, cardiac or striated; or glands) in the periphery; those fibres exiting a specific cell group (i.e., efferent fibres of the basilar pons), used in reference to a cell group. (05 Mar 2000) |
| efferent glomerular arteriole | The vessel that carries blood from the glomerular capillary network to the capillary bed of the proximal convoluted tubule; collectively, these vessels constitute the renal portal system. Synonym: arteriola glomerularis efferens, vas efferens, efferent vessel. (05 Mar 2000) |
| efferent nerve | <anatomy, nerve> A nerve which transmits impulses from the brain and spinal cord to a muscle or organ. (27 Sep 1997) |
| efferent pathways | Nerve structures through which impulses are conducted from a nerve centre toward a peripheral site. (12 Dec 1998) |
| afferent vessel | A vessel carrying blood toward the heart. A vein or venule. (12 Dec 1998) |
| air vessel | A vessel, cell, duct, or tube containing or conducting air; as the air vessels of insects, birds, plants, etc.; the air vessel of a pump, engine, etc. For the latter, see Air chamber. The air vessels of insects are called tracheae, of plants spiral vessels. Source: Websters Dictionary (01 Mar 1998) |
| anastomosing vessel | A vessel that establishes a connection between arteries, between veins, or between lymph vessels. Synonym: vas anastomoticum. (05 Mar 2000) |
| blood vessel | <anatomy> All the vessels lined with endothelium through which blood circulates. (18 Nov 1997) |
| blood vessel prosthesis | Prosthesis, constructed of either synthetic or biological material, which is used for the repair of injured or diseased blood vessels. (12 Dec 1998) |
| blood vessel prosthesis implantation | Surgical insertion of synthetic or biological material to repair injured or diseased blood vessels. (12 Dec 1998) |
| capillary vessel | <anatomy> Any one of the minute vessels that connect the arterioles and venules, forming a network in nearly all parts of the body. Their walls act as semipermeable membranes for the interchange of various substances, including fluids, between the blood and tissue fluid. Synonym: vas capillare. Origin: L. Capillaris = hair like (16 Dec 1997) |
| vessel | Water conducting system in the xylem, consisting of a column of cells (vessel elements) whose end walls have been perforated or totally degraded, resulting in an uninterrupted tube. (18 Nov 1997) |
