1-What are the major functions of the cardiovascular system? (5 points)
Major functions include transportation of nutrients and oxygen, removal of waste products, regulation
of body temperature, hormonal transport, and immune system support.
2-Which signs and symptoms are associated with common cardiovascular system disorders? (10 points)
Common cardiovascular disorders include conditions such as hypertension, coronary artery disease,
heart failure, and arrhythmias. The associated signs and symptoms can vary depending on the specific
disorder, but some general indicators include:
1. Chest Pain or Discomfort: Often described as pressure, squeezing, or fullness in the chest, this
symptom can indicate conditions such as angina or myocardial infarction.
2. Shortness of Breath: This can occur during physical activity or at rest and may be a sign of heart
failure or other cardiovascular issues.
3. Fatigue: Unusual tiredness or lack of energy can be a symptom of heart disease, especially in
women.
4. Palpitations: The sensation of a rapid or irregular heartbeat can indicate arrhythmias or other heart
conditions.
5. Swelling (Edema): Fluid retention leading to swelling in the legs, ankles, or abdomen can be a sign
of heart failure.
6. Dizziness or Lightheadedness: This may occur due to decreased blood flow or arrhythmias.
7. Nausea or Vomiting: These symptoms can sometimes accompany heart-related issues, particularly
in women.
8. Cold Sweats: Profuse sweating without exertion may indicate a serious cardiovascular event.
9. High Blood Pressure: Often asymptomatic, hypertension can lead to significant cardiovascular
complications if left untreated.
10. Cyanosis: A bluish tint to the skin, especially around the lips or fingertips, can indicate inadequate
oxygenation due to heart problems.
