The cardiovascular (circulatory) system is a complex and vital network that ensures the continuous circulation of blood throughout the body. It functions as a flawless mechanism, delivering oxygen, nutrients and hormones to every cell, whilst also removing waste products and carbon dioxide for subsequent elimination.
Main components of the system:
- Heart: A powerful muscle pump that works non-stop, pumping blood throughout the body.
- Arteries: Strong and elastic blood vessels through which oxygen-rich blood flows from the heart to the organs and tissues.
- Veins: The blood vessels that carry “used” blood back to the heart and lungs to be re-oxygenated.
- Capillaries: The smallest blood vessels, where the exchange of substances between the blood and the cells takes place directly.
Key features:
- Transport: Rapid and uninterrupted supply of oxygen and nutrients to the tissues.
- Thermoregulatory: Maintaining a stable body temperature by dilating or constricting blood vessels (this is particularly important during aquatic, thermal or physiotherapy treatments).
- Protective: Transporting immune system cells to enable a rapid response to infections and inflammation.
Healthy blood circulation is the foundation of good health, high energy levels and the body’s ability to recover quickly. Maintaining healthy blood vessels and ensuring the heart functions properly are key to preserving vitality and improving overall health.
