🫀 Primary Functions of the Cardiovascular System

The cardiovascular system is responsible for:

• Transporting oxygen and nutrients to cells
• Removing carbon dioxide and waste
• Regulating body temperature
• Maintaining blood pressure
• Supporting immune response
• Delivering hormones throughout the body


🧬 Major Components

Heart

• Pumps blood throughout the body
• Has four chambers:

  • Right atrium

  • Right ventricle

  • Left atrium

  • Left ventricle

Blood Vessels

Arteries – carry blood away from the heart
Veins – carry blood toward the heart
Capillaries – allow gas and nutrient exchange

Blood

Red blood cells (RBCs) – carry oxygen
White blood cells (WBCs) – fight infection
Platelets – help with clotting
Plasma – liquid portion of blood


🔄 Blood Flow Pathway

  1. Right atrium

  2. Right ventricle

  3. Lungs (oxygenation)

  4. Left atrium

  5. Left ventricle

  6. Body tissues

📌 The left ventricle is the strongest chamber.


💓 Heartbeat Cycle

Systole – heart contracts
Diastole – the heart relaxes

Normal adult heart rate:
60–100 beats per minute


🩺 Vital Signs & Circulation

Blood pressure measures arterial pressure
Pulse reflects heart rate
Oxygen saturation shows oxygen levels
Capillary refill indicates circulation quality

Normal BP: 120/80 mmHg


⚠️ Common Cardiovascular Conditions

• Hypertension (high blood pressure)
• Hypotension (low blood pressure)
• Atherosclerosis
• Arrhythmia
• Myocardial infarction (heart attack)
• Stroke


🧪 Diagnostic Tests

• Blood pressure measurement
• Electrocardiogram (ECG/EKG)
• Pulse oximetry
• Cholesterol testing
• Cardiac enzymes


🧠 Exam Tips (CMA Focus)

✔ Arteries = away from the heart
✔ Veins = toward heart
✔ Left ventricle = strongest chamber
✔ Pulse taken at radial artery
✔ Blood pressure taken over the brachial artery


📘 Quick Memory Aid

“A-V Away”
➡ Arteries carry blood away from the heart


🩺 Clinical Reminder

Always:
• Verify patient identity
• Position patient correctly
• Use the correct cuff size
• Document findings immediately


💡 CMA Mastery Series Tip
