Study Notes
Cardiovascular System Components
- The cardiovascular system consists of the heart, blood vessels, and blood.
Blood Supply to AV Node
- The artery that supplies the AV node in the majority of people is the right coronary artery.
B-Type Natriuretic Peptide Function
- The primary function of B-Type natriuretic peptide produced by ventricular myocytes is to reduce blood volume and pressure by promoting vasodilation and increasing sodium excretion.
Veins and Right Atrium
- The vein that opens into the right atrium just to the left of the mouth of the inferior vena cava is the coronary sinus.
Dominant Pacemaker in Healthy Heart
- The dominant pacemaker in a healthy heart is the sinoatrial (SA) node.
Sympathetic Innervation
- Sympathetic innervation supplies the AV node, SA node, and cardiac muscle from the cervical and thoracic regions of the spinal cord.
Core Functions of Cardiovascular System
- The core functions of the cardiovascular system are transportation of oxygen and nutrients, removal of waste products, regulation of body temperature, and maintenance of blood pressure.
Non-Core Functions
- The cardiovascular system is not responsible for digestion or absorption of nutrients.
Body Fluid Compartments
- Examples of body fluid compartments include intravascular, interstitial, and intracellular fluids.
Primary Function of Blood Vessels
- The primary function of blood vessels in the cardiovascular system is to transport blood throughout the body.
Protection against Infection and Blood Loss
- The primary function of platelets and the coagulation cascade is to protect against infection and blood loss in the cardiovascular system.
