Cardiovascular Physiology
Introduction
Cardiovascular physiology refers to the study of how the heart and blood vessels function together to circulate blood throughout the body. Understanding this system helps in diagnosing and treating various heart conditions.
Components of the Cardiovascular System
- Heart – The muscular organ that pumps blood.
- Blood Vessels – Arteries, veins, and capillaries that transport blood.
- Blood – Carries oxygen, nutrients, and waste products.
How the Heart Works
- The heart has four chambers: two atria and two ventricles.
- It pumps blood in a two-circuit system: the systemic circulation, which supplies oxygenated blood to the body, and the pulmonary circulation, which sends blood to the lungs to receive oxygen.
- The electrical system of the heart regulates contractions through the sinoatrial (SA) node, making sure the heartbeat is coordinated.
Blood Pressure and Circulation
- Systolic pressure (upper number) – Pressure when the heart contracts.
- Diastolic pressure (lower number) – Pressure when the heart relaxes.
- Healthy blood pressure is generally less than 120/80 mmHg.
Heart Rate and Cardiac Output
- Normal heart rate: 60-100 beats per minute.
- Cardiac output is the amount of blood pumped per minute and depends on heart rate and stroke volume.
Importance of Cardiovascular Health
- Regular exercise strengthens the heart.
- A healthy diet rich in fruits, vegetables, and fiber reduces the risk of heart disease.
- Controlling risk factors like high blood pressure, diabetes, and cholesterol is essential.
Conclusion
Understanding cardiovascular physiology is crucial to maintaining heart health and preventing diseases. By making lifestyle changes and seeking regular medical check-ups, you can support a healthy cardiovascular system.

If you or your loved ones experience any of these symptoms, you should consult a doctor in time. Remember that self-medication can be dangerous, and timely diagnosis will preserve the quality and life expectancy.
The heart is an organ that does not know how to "keep silent" if something goes wrong. Chest pain, shortness of breath, swelling, dizziness, and rhythm disturbances are the symptoms that require our attention. The best prevention of heart disease is careful attention to your health, regular checkups with a doctor, and a healthy lifestyle. Take care of your heart, and it will serve you for many years!
