The circulatory system is responsible for transporting nutrients, water, and oxygen to various cells in your body and carrying away wastes such as carbon dioxide that body cells produce.
The circulatory System can be divided into 3 major parts:
- Heart
- Blood
- Blood Vessels
The health of the circulatory system depends on the functioning of the heart, blood and blood vessels. The circulatory system works in two linked circuits, the pulmonary circuit carries blood to the lungs for oxygenation while in the systemic circuit the oxygenated blood is supplied to various parts of the body. Any disturbance or irregularity in this cycle leads to medical conditions, which range from mild to severe.
Functions of the circulatory system:
- Transport nutrients to cells
- Collect wastes from cells
- Carry oxygen from lungs to cells
- Carry CO2 back from the cells to lungs
- Maintain body temperature
- Stabilise the PH and ionic concentration of body fluids
- Transport hormones
Various diseases caused due to disorder of the circulatory system:
- Angina
- Arrhythmia
- Atherosclerosis
- Arteriosclerosis
- Cardiomyopathy
- Congenital Heart Defect
- Coronary Artery Disease
