SEM 2 chapter 22 intro to cardio Quiz 1

Cardiovascular System Function

Supplies body cells with oxygen-rich blood and eliminates carbon dioxide and other wastes.

Leading cause of death

Cardiovascular disease is the leading cause of death for adults in the United States.

Human heart transplantation

A significant advancement in treatment for heart disease.

Risk factor management strategies

Includes lifestyle modifications and regular health screenings.

Sarcopenia

Age-related loss of muscle mass and strength impacting cardiac output.

Diastole

The filling phase of the cardiac cycle.

Sinoatrial (SA) node

The primary pacemaker of the heart that initiates electrical impulses.

Cardiac output

The amount of blood the heart pumps per minute, measured in liters.

Normal heart rate ranges

Typically ranges from 60 to 100 beats per minute in adults.

Importance of ECG

It is crucial for diagnosing heart conditions by detecting electrical activity.

Baroreceptors

Sensors that monitor blood pressure and help regulate heart rate.

Exercise recommendations

At least 150 minutes of moderate aerobic activity per week for cardiovascular health.

Coronary circulation

The supply of blood to the myocardium during diastole.

Cardiovascular health assessment

Includes client symptom descriptions, past medical history, and physical examinations.

Holter monitoring

Continuous ECG monitoring to detect transient arrhythmias during daily activities.

Total artificial hearts

Artificial devices developed as a treatment option for heart disease.

Atrial fibrillation

A common arrhythmia characterized by disorganized electrical activity of the heart.

Cardiac catheterization

A procedure used to diagnose and treat certain cardiovascular conditions.

Lifestyle modifications

Changes in diet, exercise, and health monitoring that improve cardiovascular health.

Symptoms of heart failure

Fatigue, shortness of breath, and increased risk during activities.

Importance of early detection

Early intervention significantly improves prognosis in cardiovascular diseases.

Cholesterol screenings

Routine monitoring recommended for managing cardiovascular risk factors.
