Study Notes
Circulatory System Overview
- The circulatory system is a transport system that transports materials throughout the body.
- It transports materials to body cells and organs.
Functions of the Circulatory System
- Transports oxygen and nutrients to body cells.
- Transports carbon dioxide and metabolic waste to organs for disposal.
Components of the Circulatory System
- The circulatory system consists of three main parts: heart, blood vessels, and blood.
Heart Structure and Function
- The heart is a muscular organ that pumps blood.
- The heart has four chambers: right atrium, right ventricle, left atrium, and left ventricle.
Heart Chamber Functions
- The atria are receiving chambers.
- The ventricles are pumping chambers that create pressure to transport blood.
Blood Composition
- Blood consists of two main components: cellular and liquid components.
Circulatory System Divisions
- The circulatory system is divided into two parts: pulmonary and systemic.
- The pulmonary system receives deoxygenated blood and converts it into oxygenated blood through gas exchange.
Blood Flow
- Deoxygenated blood enters the right atrium and then flows into the right ventricle.
- From the right ventricle, blood is pumped into the pulmonary artery, where it is oxygenated.
Valve Function
- Valves in the heart ensure that blood flows in one direction and does not flow back into the atrium.
