Study Notes
Cardiovascular System Overview
- Comprises three main components: blood, heart, and blood vessels.
Functions of the Cardiovascular System
-
Heart Function: Acts as a pump, propelling blood throughout the network of blood vessels.
-
Oxygen and Nutrient Transport: Blood delivers oxygen and essential nutrients to cells, facilitating cellular functions.
-
Waste Removal: Transports carbon dioxide and metabolic wastes away from cells, ensuring detoxification and homeostasis.
-
Regulation of Acid-Base Balance: Blood plays a key role in maintaining the pH level of body fluids, crucial for overall metabolic processes.
-
Temperature Regulation: Helps in maintaining body temperature through the distribution of heat generated by metabolic activities.
-
Water Content Maintenance: Blood components are integral in regulating the water content of body fluids, aiding in fluid balance.
-
Defense Against Disease: Various blood components, such as white blood cells, provide immunity and protect the body from pathogens.
-
Repair Mechanisms: Blood components, including platelets and clotting factors, are essential for repairing damaged blood vessels and minimizing blood loss.
