Explore the human circulatory system, including the heart, blood vessels, and blood, vital for transporting oxygen and nutrients. Learn about cardiovascular diseases, their risk factors, and the role of lifestyle in managing these conditions. Diagnostic techniques and surgical treatments for circulatory disorders are also discussed, alongside a look at the evolution of circulatory systems in biology and historical advancements in our understanding.

The heart is responsible for pumping blood throughout the body
Arteries
Arteries carry oxygen-rich blood away from the heart to the body's cells
Veins
Veins carry oxygen-depleted blood back to the heart
Capillaries
Capillaries are tiny blood vessels that allow for the exchange of nutrients and waste products between the blood and cells
Blood carries oxygen, nutrients, and waste products throughout the body
Cardiovascular diseases, such as coronary artery disease and hypertension, can affect the heart and blood vessels
Hematologic diseases, like anemia, affect the blood itself
Lymphatic diseases impact the lymphatic system, which is vital for immune function
Cardiologists are medical doctors who specialize in the heart
Cardiothoracic and vascular surgeons are trained to perform surgical procedures on the heart and blood vessels
Basic Assessments
Basic assessments, such as checking the pulse and blood pressure, can help diagnose circulatory system conditions
Invasive Procedures
Invasive procedures, like cardiac catheterization, can provide more detailed information about the heart and blood vessels
Imaging Techniques
Imaging techniques, such as echocardiography and MRI, can provide detailed images of the heart and blood vessels to aid in diagnosis
Coronary Artery Bypass Grafting (CABG)
CABG is a surgical procedure that reroutes blood around clogged arteries to improve blood flow to the heart
Angioplasty with Stent Placement
Angioplasty with stent placement is a procedure that opens narrowed arteries and helps prevent them from narrowing again
Other Procedures
Other procedures, such as valve repair or replacement, can treat specific heart conditions
Circulatory systems vary among different organisms, with vertebrates having a closed system and invertebrates having an open system
Our understanding of the circulatory system has evolved over time, with William Harvey's work in the 17th century being a significant milestone in its study
00
Function of human circulatory system
Transports oxygen, nutrients, waste; sustains life by exchanging substances with cells.
01
Common cardiovascular diseases
Includes coronary artery disease, hypertension; involves heart and blood vessels.
02
Differences between cardiologists and cardiothoracic surgeons
Cardiologists treat heart conditions medically; cardiothoracic surgeons perform heart surgeries.
