Answer 15

An integrated group of cells with a common function, structure, or both.

Question 16

Tricuspid Valve

Answer 16

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.

Question 17

Valve

Answer 17

A body structure that temporily closes a passage or oriface, or permits movement of fluid in only one direction

Question 18

Blood Pressure

Answer 18

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.

Question 19

Cardiology

Answer 19

The study of the heart and its action and diseases.

Question 20

Diastole

Answer 20

The stage of the heart cycle in which the heart muscle is relaxed, allowing the chambers to fill with blood.

Diastolic Pressure

Answer 21

Blood pressure that remains between heart contractions.

Question 22

Electrocardiogram (EKG)

Answer 22

A measurement of heart electrical activity.

Question 23

Hypothesis

Answer 23

A tentative answer to a well-framed question that can be tested by an experiment.

Question 24

Sinoartrial Node

Answer 24

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.

Question 25

Sphygmomanometer

Answer 25

An instrument for measuring blood pressure and especially arterial blood pressure.

Question 26

Systole

Answer 26

The stage of the heart cycle in which the heart muscle contracts and the chambers pump blood.

Question 27

Systolic Pressure

Answer 27

Blood pressure in the arteries during contraction of the ventricles.

Question 28

Biopsy

Answer 28

The removal and examination of tissues, cells, or fluids from the living body.
