Study Notes
Circulatory System
- The circulatory system is essential for moving nutrients and oxygen throughout the body
- Arteries carry blood away from the heart
- Veins carry blood back to the heart
- Capillaries connect arteries and veins, allowing for gas and nutrient exchange
- Arteries have thick, muscular, and elastic walls, which help them to withstand the high pressure of blood pumped by the heart
- Veins have thinner walls and contain valves to prevent blood from flowing backward
- Capillaries have very thin walls, facilitating the efficient exchange of materials.
- The heart is a muscular pump that circulates blood throughout the body
- The heart is composed of four chambers: two atria and two ventricles
- The atria receive blood, and the ventricles pump blood
- Major blood vessels include the aorta and vena cava
- Blood carries oxygen, nutrients, and other essential substances throughout the body
- The heart has valves to ensure one-way blood flow
