Heart

Question 1

cardiovascular system

Answer 1

The Cardiovascular system is a system of blood vessels, all going to and from the heart…transport oxygen etc…This network takes out waste, and discards it, while maintaining important elements in the body.

Question 2

chambers

Answer 2

The Chambers are the “rooms” of the heart. These consist of the Atriums (Top Sections), and the ventricles (Bottoms Sections).

Question 3

walls

Answer 3

The walls of the heart are responsible for the contracting (squeezing) and relaxing to send blood throughout the body.

Question 4

septum

Answer 4

A layer in the middle of the heart divides it into two left and rights sides

Question 5

layers of the heart - inner

Answer 5

Endocardium - Inner

Question 6

middle layer

Answer 6

Myocardium - Middle Muscular Layer

Question 7

outer layer

Answer 7

Epicardium - [PROTECTIVE] Outer Layer

Question 8

top part of the heart

Answer 8

atriums

Question 9

bottom part of the heart

Answer 9

ventricles

Question 10

right atrium

Answer 10

is responsible for receiving oxygen deficient blood from two large veins (Superior and Inferior Vena Cava[s]).

Question 11

left atrium

Answer 11

is responsible for receiving oxygen from the pulmonary veins. The pulmonary veins bring oxygen-filled blood from the lungs to the left atrium.

Question 12

right ventricle

Answer 12

pumps oxygen-deficient blood to the lungs to get more oxygen

Question 13

left ventricle

Answer 13

takes oxygen-sufficient blood, and pumps it to the rest of the body

Question 14

heart valves

Answer 14

open and close to allow blood to flow properly

Question 15

atrioventricular valves

Answer 15

open between upper and lower chambers (tricuspid, mitral)

Question 16

tricuspid valve

Answer 16

between right and left atrium

Question 17

mitral valve

Answer 17

between left ventricle and left atrium

Question 18

Semilunar valves

Answer 18

open when blood flows out of ventricles (aortic/pulmonary)

Question 19

aortic valve

Answer 19

opens when blood flows out of left ventricle to aorta

Question 20

pulmonary valve

Answer 20

opens when blood flows out of right ventricle to pulmonary arteries [OP]

Question 21

arteries

Answer 21

carry oxygen rich blood from heart to body’s tissues

Question 22

veins

Answer 22

carry oxygen poor blood back to your heart

Question 23

capillaries

Answer 23

small vessels that exchange oxygen rich and poor blood

Question 24

sinoatrial node

Answer 24

sends signal to make heart beat

Question 25

atrioventricular node

Answer 25

carries electrical signals from upper chambers to lower ones

Question 26

respiration

Answer 26

amount of times you breath in a minute

Question 27

p wave

Answer 27

atrial depolarization

Question 28

QRS complex

Answer 28

measures ventricular depolarization and atrial repolarization

Question 29

t wave

Answer 29

ventricular repolarization (resting)

Question 30

systolic pressure

Answer 30

how much pressure blood is exerting on artery walls when heart beats

Question 31

diastolic pressure

Answer 31

how much pressure blood exerts against artery walls while heart is resting

Question 32

normal blood pressure

Answer 32

120/80

Question 33

normal oxygen saturation

Answer 33

95-100% measures amount of hemoglobin in the blood

Question 34

arrhythmias

Answer 34

irregular heartbeat/ also called dysrhythmias

Question 35

tachicardia

Answer 35

too fast >100

Question 36

bradicardia

Answer 36

too slow <60

Question 37

supraventricular arrythmias

Answer 37

in atria

Question 38

ventricular arrythmias

Answer 38

ventricles

Question 39

bradyarrythmias

Answer 39

slow arrythmia

Question 40

ECG

Answer 40

Electrocardiogram- measuring the DEPOLARIZATION AND REPOLARIZATION OF THE HEARTS CELLS.
