Bio medical science terms quiz Flashcards
Define
Pump
A device that raises, transfers, delivers, or compresses fluids or gases especially by suction or pressure or both.
Fluid Mechanics
A branch of mechanics dealing with the properties of liquids and gases.
Positive Displacement Pump
A type of pump that uses positive pressure to move a fluid.
Aorta
The large arterial trunk that carries blood from the heart to be distributed by branch arteries through the body.
Aortic Valve
The semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle.
Artery
Any of the tubular branching muscular and elastic-walled vessels that carry blood from the heart through the body.
Atrium
An anatomical cavity or passage; especially: a chamber of the heart that receives blood from the veins and forces it into a ventricle or ventricles.
Cardiovascular System
The transport system of the body responsible for carrying oxygen and nutrients to the body and carrying away carbon dioxide and other wastes; composed of the heart, blood vessels, and blood.
Cell
The smallest structural unit of living matter capable of functioning independently.
Histology
A study of tissues.
Inferior Vena Cava
A vein that is the largest vein in the human body and returns blood to the right atrium of the heart from body parts below the diaphragm.
Mitral Valve (bicuspid valve)
A valve in the heart that guards the opening between the left atrium and the left ventricle; prevents the blood in the ventricle from returning to the atrium. Alternative name is bicuspid valve.
Pericardium
The membrane that encloses the heart.
Superior Vena Cava
A vein that is the second largest vein in the human body and returns blood to the right atrium of the heart from the upper half of the body.
Tissue
An integrated group of cells with a common function, structure, or both.
Tricuspid Valve
A valve that is situated at the opening of the right atrium of the heart into the right ventricle and resembles the mitral valve in structure but consists of three triangular membranous flaps.
Valve
A body structure that temporily closes a passage or oriface, or permits movement of fluid in only one direction
Blood Pressure
Pressure exerted by the blood upon the walls of blood vessels and especially arteries, usually measured on the radial artery by means of a sphygmomanometer, and expressed in millimeters of mercury.
Cardiology
The study of the heart and its action and diseases.
Diastole
The stage of the heart cycle in which the heart muscle is relaxed, allowing the chambers to fill with blood.
Diastolic Pressure
Blood pressure that remains between heart contractions.
Electrocardiogram (EKG)
A measurement of heart electrical activity.
Hypothesis
A tentative answer to a well-framed question that can be tested by an experiment.
Sinoartrial Node
A small mass of tissue that is made up of Purkinje fibers, ganglion cells, and nerve fibers, that is embedded in the musculature of the right atrium, and that originates the impulses stimulating the heartbeat called also S-A node, sinus node.
Sphygmomanometer
An instrument for measuring blood pressure and especially arterial blood pressure.
Systole
The stage of the heart cycle in which the heart muscle contracts and the chambers pump blood.
Systolic Pressure
Blood pressure in the arteries during contraction of the ventricles.
Biopsy
The removal and examination of tissues, cells, or fluids from the living body.
Erythrocyte
A red blood cell; the major cell component of blood whose primary function is to carry oxygen.
Hemoglobin
An iron-containing respiratory pigment of vertebrate red blood cells that functions primarily in the transport of oxygen from the lungs to the tissues of the body.
Histology
The study of tissues
Leukocyte
A white blood cell; primary function is defenses against foreign materials as part of the immune system.
Plasma
The fluid part especially of blood or lymph.
Platelet
A component of mammalian blood that lacks a nucleus and is derived from fragments of megakaryocyte cytoplasm, and that assists in blood clotting, also called a thrombocyte.
Tissue
An integrated group of cells with a common function, structure, or both.
