Study Notes
Circulatory System Function
- The circulatory system is responsible for transporting oxygen, nutrients, and hormones throughout the body.
- It also removes waste products like carbon dioxide.
Arteries
- Arteries carry oxygenated blood away from the heart.
Platelets
- Platelets are responsible for blood clotting.
- They adhere to damaged blood vessel walls, forming a plug to stop bleeding.
Renin-Angiotensin-Aldosterone System
- The renin-angiotensin-aldosterone system is a complex hormonal pathway that regulates blood pressure.
- Renin, an enzyme secreted by the kidneys, triggers the production of angiotensin II, which constricts blood vessels and increases blood pressure.
Gas Exchange
- Gas exchange is the process of oxygen and carbon dioxide moving between the lungs and the blood.
- It occurs in the alveoli, tiny air sacs in the lungs.
