Study Notes
Circulatory System
- The system of organs involved in blood circulation is known as the circulatory system, comprising the heart, blood vessels, and the blood itself.
- This system is essential for transporting nutrients, gases, hormones, and waste products throughout the body.
Terminology
- The term 'kardia' in Greek translates to 'heart,' highlighting its central role in the circulatory process.
- The Latin term 'vascula' means 'vessels,' referring to the network of arteries, veins, and capillaries that carry blood.
Circulation Types
- The systemic circulation is responsible for transporting oxygen-rich blood from the heart to the rest of the body, ensuring tissue oxygenation and nutrient delivery.
Vertebrate Circulatory System
- Vertebrates possess a closed circulatory system, characterized by blood contained within vessels, allowing for more efficient transport and regulation of blood flow.
Great Vessels of the Heart
- The great vessels of the heart include large elastic arteries, such as the aorta, and large veins, including the superior and inferior vena cavae, crucial for transporting blood to and from the heart.
