# Cardiovascular System Notes ## Small and Large Circulation * **Small Circulation (Pulmonary):** Blood travels from the right ventricle to the lungs, where it's oxygenated, then returns to the left atrium. * **Path:** Right Ventricle → Pulmonary Artery → Lungs → Pulmonary Veins → Left Atrium * **Large Circulation (Systemic):** Oxygenated blood is pumped from the left ventricle to the body's organs and tissues, collecting deoxygenated blood, and returning to the right atrium. * **Path:** Left Ventricle → Aorta → Organs & Tissues → Vena Cavae → Right Atrium ## Cardiovascular Diseases * **Atherosclerosis:** The buildup of fats on the artery walls. * **Blood Clotting:** Blood clots, or plaques, narrow the arteries, restricting blood flow. * **Stroke (CVA):** Blockage or rupture of blood vessels in the brain. * **Myocardial Infarction (Heart Attack):** A coronary artery gets blocked, damaging the heart muscle. ## Measures for Healthy Cardiovascular System * **Quit Smoking:** Avoid tobacco. * **Manage weight and nutrition:** Monitor salt, alcohol and fat intake, choosing vegetables, fruits, and whole grains. * **Monitor Cholesterol levels:** Regularly check and control cholesterol levels. * **Control blood glucose levels:** Maintain healthy glucose levels. * **Regular Blood Pressure Checks:** Monitor blood pressure. * **Manage Stress:** Find healthy methods to cope with stress. * **Physical Exercise:** Engage in regular physical activity. **Note:** Some abbreviations are unclear, and a few terms might need clarification.
