Unit 5 - Lesson 2: Cardiovascular & Hemotalogic Sytems

Question 1

A heart rate lower than 60 BPM

Answer 1

Bradycardia

Question 2

A heart rate higher than 100 BPM

Answer 2

Tachycardia

Question 3

The top two chambers of the heart that receive blood from other parts of the body

Answer 3

Atria

Question 4

Bottom two chambers of the heart that supply purified blood to the other parts of the body; larger and thicker than atria

Answer 4

Ventricles

Question 5

There are four main these in the heart that open and close to move blood in one direction between the heart chambers

Answer 5

Valves

Question 6

The flow of blood through the heart, valves, and vessels to and from the body

Answer 6

Cardiac cycle

Question 7

Period of heart relaxation; the flow of blood is passive and only due to gravity

Answer 7

Diastole

Question 8

Period of heart contraction; the flow of blood is faster due to the force of contraction

Answer 8

Systole

Question 9

Blood vessels that carry blood away from the heart

Answer 9

Arteries

Question 10

Blood vessels that carry blood to the heart

Answer 10

Veins

Question 11

Amount of blood pumped by the left ventricle of the heart per single heartbeat; normal valve is 60 to 80 mL per beat

Answer 11

Stroke volume

Question 12

Number of heart contractions per minute, measured in beats per minute BPM

Answer 12

Heart rate

Question 13

Volume of blood pumped by heart per minute; can be calculated by multiplying the stroke volume and the heart rate; normal value is 4 to 8 L

Answer 13

Cardiac output

Question 14

Arteries and veins that carry blood to or away from the heart

Answer 14

Vessels

Question 15

Disorganized or abnormal heartbeat or irregular heart rate

Answer 15

Dysrhythmias

Question 16

Increased blood pressure over certain period of time; normal BP = 120/80 mmHg

Answer 16

Hypertension

Question 17

Increase in cholesterol; typically LDL (Low density lipoproteins) > 100

Answer 17

Hyperlipidemia

Question 18

Medications or agents that cause blood vessels to constrict

Answer 18

Vasoconstrictors

Question 19

Medications or agents that cause blood vessels to dilate

Answer 19

Vasodilators

Question 20

The measurement of the blood pressure during systole or the period of ventricle contraction; the highest exerted pressure on the arterial wall

Answer 20

Systolic blood pressure (SBP)

Question 21

The measurement of blood pressure during diastole or relaxation; the lowest exerted pressure on the arterial wall

Answer 21

Diastolic blood pressure (DBP)

Question 22

Arteries that supply oxygen rich blood to the heart itself

Answer 22

Coronary arteries

Question 23

A lack of oxygen due to an obstruction significant enough to deprive heart muscles of oxygen

Answer 23

Ischemia

Question 24

Chest pain that’s caused by ischemia or lack of oxygen

Answer 24

Angina

Question 25

Occurs when a rupturing of plaque results in a blood clot in the coronary arteries

Answer 25

Acute coronary syndrome (ACS)

Question 26

A condition in which complete obstruction of the coronary artery results in death of the heart muscle

Answer 26

Acute myocardial infarction (AMI)

Question 27

The composition, formation, and transportation of blood; also, blood’s functions within the body

Answer 27

Hematologic system

Question 28

A type of blood cell, also called red blood cells or RBCs

Answer 28

Erythrocytes

Question 29

A type of blood cell; also called white blood cells or WBCs

Answer 29

Answer 30

Thrombocytes

Question 31

The liquid portion of blood

Answer 31

Question 32

The process of blood clotting

Answer 32

Coagulation

Question 33

Formation of blood cells in the bone marrow

Answer 33

Hematopoiesis

Question 34

Low levels of red blood cells in the blood

Answer 34

Anemia

Question 35

A type of cancer that results in abnormal production of white blood cells

Answer 35

Leukemia

Question 36

A platelet disorder characterized by an abnormally low level of platelets in the blood

Answer 36

Thrombocytopenia

Question 37

A condition where neutrophil count is abnormally low in the blood

Answer 37

Neutropenia

Question 38

Condition of having blood clots in deep veins, such as lower extremities

Answer 38

Deep vein thrombosis (DVT)
