Cardiovascular Systems

Cardiovascular systems refer to the heart and blood vessels working together to circulate blood throughout the body. The heart acts as a pump, pushing oxygen-rich blood from the lungs to organs and tissues, and returning oxygen-poor blood back to the lungs. Blood vessels—including arteries, veins, and capillaries—serve as channels guiding blood flow. This system supplies essential nutrients and oxygen, removes waste products, and helps maintain blood pressure. A healthy cardiovascular system is vital for overall well-being, supporting energy levels and organ function, while issues like blockages or high blood pressure can impact health significantly.
