Cardiovascular System Flashcards

Study Notes

Cardiovascular System Overview

Maintains homeostasis by continually redirecting blood flow to active tissues.
Key organs include the heart, blood vessels, arteries, and veins.

Functioning of the Cardiovascular System

Blood vessels transport blood to and from the heart; arteries move blood away while veins return it.
The system delivers oxygen, nutrients, and hormones to cells, and removes waste products like carbon dioxide.

Consequences of System Failure

Heart failure occurs when the heart cannot pump blood efficiently.
Symptoms of heart failure include fatigue, shortness of breath, and difficulty in performing everyday activities.

Importance of the Heart

The heart is the central organ of the cardiovascular system, serving as a muscular pump for blood circulation.
Functions primarily to ensure oxygen and nutrient transport throughout the body.

Cardiovascular System Functions

Essential for transporting oxygen, nutrients, and metabolic byproducts.
Plays a crucial role in adapting to physical activity, exercise, and stress conditions.

Regulation of Body Temperature

Blood circulation helps regulate body temperature by distributing heat.

Interconnection with Other Body Systems

Works closely with the respiratory system to provide oxygen and remove carbon dioxide from the body.
Ensures nutrient supply and waste removal, integrating with other physiological systems.

Interaction with the Nervous System

Provides the brain with a continuous supply of oxygen-rich blood.
The brain regulates heart rate and blood pressure, facilitating coordination between both systems.
