Front 8

Mitral Valve

Back 8

A valve in the heart that guards the opening between the left atrium and the left ventricle; prevents the blood in the ventricle feom returning to the atrium.

Front 9

Pulmonary Circulation

Back 9

The passage of the venous blood from the right atrium of the heart to the right ventricle and pulmonary arteeies to the lungs where it is oxygenated and its return via the pulmonary veins to entee the left atrium and participate in systemic circulation.

Front 10

Superior Vena Cava

Back 10

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.

Front 11

Systemic Circulation

Back 11

The branxh of the circulatory system that supplies all body organs and then returns oxygen-poor blood to the right atrium via veins.

Front 12

Tissue

Back 12

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

Front 13

Tricuspid valve

Back 13

A valve that is situated at the opening of the right atrium of the heart into the right ventricle and that resembles the mitral valve in structure but consists of three triangular membranous flaps.

Front 14

Valve

Back 14

A body structure that temporarily closes a passage or orfice or permits movement of fluid in only one direction.

Front 15

Vein

Back 15

A vessel that returns blood to the heart.

Front 16

Doem veins move blood away from the heart?

Back 16

No arteries carry oxygenated blood away from the heart. Veins carry deoxygenated blood to the heart.

Front 17

How do the heart and lungs work together to pick up and deliver oxygen to the cells.

Back 17

Heart pumps blood tot he lings to release carbon dioxide and then oxygenate blood. It is then pumped to the rest of the body.

Front 18

Structure of arteries

Back 18

Thick muscular walls, much elastic tissue, small lumen relative diameter, not permeable, vales in pulmonary artery and aorta only, blood under high pressure , blood moves in pulses, and blood flows rapidly.

Front 19

Structure of vein

Back 19

Thin muscular walls, little elastic tissue, large lumen relative diameter, not capable of construction, not permeable, vlaves throughout all veins, blood low pressure, no pulses, and blood flows slowly.

Front 20

Atrioventricular node

Back 20

A specialized mass of conducting cells located at the atrioventricular junction in the heart.

Front 21

Blood pressure

Back 21

Pressure exerted by the blood upon the walls of the blood vessels, especially arteries, usually measured by means of a sphymomanometer and expressed in millimeters of mercury.

Front 22

Caridology

Back 22

The study of the heart and its action and diseases.

Front 23

Diastole

Back 23

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

Front 24

Diastolic Pressure

Back 24

Blood pressure that remains between heart contractions (lower number/bottom)

Front 25

Electrocardiogram

Back 25

A measurement of heart electrical activity.

Front 26

Heart rate

Back 26

A measure of cardiac activity usually expressed as the number of beats per minute.

Front 27

Hypertension

Back 27

High blood pressure

Front 28

Pacemaker

Back 28

An electrical device for stimulating or steadying the heartbeat or reestablishing the rhythm of an arrested heartbeat.

Front 29

Pulse

Back 29

The rhythmic expansion and the recoil of arteries resulting from heart contraction; can be felt from the outside of the body.

Front 30

Sinoatrial node

Back 30

A small mass of tissue that is made up of purkinje fibers, ganglion cells, and nerve fibers, thatbis embedded in the musculature of the right atrium, and thay originates the impulses stimulating the heartbeat calked also S-A Node, sinus node.

Front 31

Systole

Back 31

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

Front 32

Systolic Pressure

Back 32

The pressure generated by the left ventricle during systole.

Front 33

In what ways can technology be used to collect and analyze cardiovascular data?

Back 33

Technology can be used to collect and analyze cardiovascular data because there are machines such as ekg which is a test that checks for problems with the electrical activity of your heart and there is also the echocardiogram which is a test. Innwhich ultrasound is used to examine the heart.

Front 34

Why is it important to monitor the rate at which the heart beats?

Back 34

So your heart doesn't overwork and cause heart failure , and so it doesn't beat too little and you not get enough blood and oxygen to your cells. To maintain homeostasis.

Front 35

What factors can influence heart rate?

Back 35

Age, gender, physical activity level, body temperature, diet, exercise, caffeine, and other drugs, stress, thyroid hormones, respiration rate, herbs, emotions, hydration levels, altitude.

Front 36

What factors can influence blood pressure?

Back 36

Age, gender, diet , physical activity, body temp, caffeine,drugs, stress, thyroid hormones, respiration rate, herbs, emotions, hydration levels.

Front 37

What is an EKG

Back 37

Used to measure electrical changes in the heart; used to diagnose heart problems.

Front 38

How do systolic and diastolic blood pressure values relate to the movement of blood in the arteries?

Back 38

If systolic and diastolic blood pressure are too high, you have hypertension. Your doctor will probably use a sphygmomanometer to measure diastolic and systolic blood pressure.

Front 39

How can an Ekg be used to diagnose and treat heart disease?

Back 39

An ekg can show signs of heart damage due to CHD and signs of a previous or current heart attack.
