Study Notes
Cardiovascular System Refresher
- The heart has 4 chambers: right and left atria (auricles) and right and left ventricles
- The pulmonary circuit carries blood to the lungs for gas exchange and back to the heart
- The systemic circuit supplies oxygenated blood to all tissues of the body and returns it to the heart
- Blood flows from the right side of the heart to the lungs and from the left side of the heart to the rest of the body
Circulatory System
- The tunica interna (tunica intima) lines the blood vessel and is exposed to blood
- Endothelium covers the inner surface of blood vessels
- Capillaries are organized into networks called capillary beds
- Precapillary sphincters control which beds are well perfused
- Thoroughfare channels are metarterioles that continue through capillary beds to venules
- Anastomosis is the point where two blood vessels merge
Prevalence of Cardiovascular Disease in Australia
- Cardiovascular disease is a significant health issue in Australia
- The prevalence of cardiovascular disease in Australia is high and requires attention
Pathophysiological Underpinnings
- Endothelial dysfunction is a key factor in cardiovascular conditions
- Nitric oxide plays a crucial role in cardiovascular health
- Inflammation is a critical component of cardiovascular disease
- Shear stress is another important factor in cardiovascular health
