Q

Control your heart contraction

A

Muscle Cells

21
Q

Occurs when there is an abnormal enlargement or bulging of an artery, often due to weakened vessel walls

22
Q

Term for the process by which the heart relaxes and fills with blood between contractions

23
Q

Blood vessel carries deoxygenated blood from the lower body back to the heart

A

Inferior Vena Cava

24
Q

Term for process by which blood vessels constrict to reduce blood flow to a specific area of the body

A

Vasoconstriction

25
Term for a condition in which the heart beats too slowly, often resulting a dizziness, fatigue or fainting
Bradycardia
26
The thickest and most muscular chamber of the heart is the
Left Ventricle
27
The coronary arteries cupply blood to which part of the heart
Myocardium
28
The “lub-dub” sound of the heartbeat is associated with
The closure of semilunar valve
29
Component of blood that is responsible for carrying oxygen throughout the body
Red Blood Cell
30
Hemoglobin, the protein that binds to oxygen in red blood cells contains which metal ion at its core
Iron (Fe)
31
Average lifespan of a red blood cells in the human bodyb
Several Months
32
What is the medical term for the condition in which the heart muscle does not pump blood effectively, leading to fluid buildup in the lungs and other body tissues
Congestive heart failure
33
Term for condition in which the heart rhythm becomes irregular
Arrhythmia
34
Responsible for carrying deoxygenated blood from the right ventricle to the lungs for oxygenation
Pulmonary Artery
35
Term for condition characterized by the buildup of fatty deposits on the inner walls of arteries, leading to reduced blood flow
Atherosclerosis
36
Chambers of the heart that receive oxygenated blood from the pulmonary veins
Left atrium

Common symptoms of angina pectoris
Chest pain or discomfort
38
Chamber of the heart that pumps oxygenated blood to the rest of the body
Left Ventricle
39
Responsible for regulating heart rate and rhythm
Sinoatrial (SA) node

Term for the condition for the contraction phase of the cardiac cycle
Diastole
41
Carrier oxygen poor blood from the body back to the heart
Superior Vena Cava
42
Occurs when there is narrowing of the coronary arteries, reducing blood flow to the heart muscle
Atherosclerosis
43
Primary function of the pericardium
Protecting the heart and anchoring it in the chest
44
What is the primary function of the pulmonary circulation
Oxygenate the blood
45
Term for a temporary interruption of blood flow to the brain, often referred to as mini stroke
MYOCARDIAL INFARCTION
