Answer 1

Irregular heart beat
Tach>100
Brady

Question 2

Heart fibrillation

Answer 2

When different fibers contract at different times

Question 3

Heart flutter

Answer 3

Similar to fibrillation; not able to build pressure

Question 4

Ischemia

Answer 4

Decline of blood supply to the heart

Question 5

Heart murmur

Answer 5

Leaky valve

Question 6

Myocarditis

Answer 6

Infection to the heart muscle

Question 7

Stenosis

Answer 7

Congenital defect; narrowing of the valves

Question 8

Myocardial infarction

Answer 8

Heart attack; death of myocardial tissue

Question 9

Angina pectoris

Answer 9

Chest pain due to a lack if oxygen/nutrient to he heart

Question 10

Portal circulation

Answer 10

Transportation of nutrients through the portal vein from the capillaries of the intestine to the liver instead of directly to the heart

Question 11

Heart sounds

Answer 11

Clicking of the valves

Question 12

Heart rate

Answer 12

Number of cardiac cycles per minute

Question 13

Stroke volume

Answer 13

Measurement of blood leaving the ventricles during a contraction

Question 14

Cardiac output

Answer 14

Heart rate plus stroke volume

Question 15

3 bypasses

Answer 15

Ductus venosus- bypass liver
Foramen ovale- bypasses right ventricle
Ductus ateriosus- bypasses lungs

Question 16

Bundle of His

Answer 16

Connects AV node to purkinje fibers

Question 17

Purkinje fibers

Answer 17

carry contraction impulses to myocardium of ventricles

Question 18

Sinoatrial node

Answer 18

controls the heart rate by sending impulses through the heart

Question 19

Atrioventricular Node

Answer 19

Recieves impulses from SA node and regulates them

Answer 20

• hormones
• chemicals
• nerve impulses
