Study Notes
Heart Layers and Functions
- The epicardium is responsible for producing serous fluid that prevents friction as the heart beats.
- The myocardium contains the contractile cardiac muscle fibers.
Circulatory System Components
- The ventricles have the thickest walls compared to the atria in the circulatory system.
Heart Layers
- The pericardium is the fibrous sac with a serous lining.
Blood Vessels
- The endothelium lines the inside of blood vessels and regulates vascular tone and blood flow.
- Elastic laminae in large arteries allow for stretching and recoil, accommodating blood pressure changes.
Capillaries
- Fenestrated capillaries allow for maximal exchange between blood and interstitial fluid.
Blood Vessels
- Veins carry blood back to the heart.
- The tunica externa is thicker than the tunica media in large veins.
Venules
- Venules collect blood from capillaries and transport it back to larger veins.
Lymphatic System
- The main function of lymphatic vessels is to collect and return interstitial fluid to the bloodstream.
