What is the primary function of the circulatory system?
What is the primary function of the circulatory system?
The delivery of oxygen and nutrients to the body's tissues and the removal of carbon dioxide and waste products.
What are the two main circuits of the circulatory system?
What are the two main circuits of the circulatory system?
The pulmonary circuit carries blood between the heart and lungs for gas exchange, while the systemic circuit carries blood between the heart and the rest of the body.
What is the difference between arteries and veins?
What is the difference between arteries and veins?
The circulatory system's network of vessels includes arteries that carry oxygenated blood away from the heart and veins that carry deoxygenated blood back to the heart.

Study Notes
Cardiovascular System Subdivisions
- The cardiovascular system has three main components: the heart, blood vessels, and blood.
- Blood is circulated through circuits: the pulmonary circuit and the systemic circuit, which includes the coronary circuit.
Arteries and Veins
- Blood vessels include arteries and veins.
Functions of Blood
- Blood carries various substances:
- Gases (oxygen and carbon dioxide) between tissues and lungs.
- Nutrients to tissues.
- Waste products (metabolites) from tissues.
- Chemical messengers (hormones) to target tissues.
- Other functions of blood:
- Maintaining acid-base balance
- Facilitating gas exchange (oxygen and carbon dioxide) in the lungs.
- Regulating water balance.
- Maintaining body temperature.
- Blood clotting (coagulation) via coagulation factors and platelets.
Components of Blood: Blood Plasma
- Blood plasma comprises approximately 55% of total blood volume.
- Plasma is primarily water (90%), with proteins, electrolytes, and gases.
- Proteins in plasma include albumin and globulins, with many proteins transporting substances.
- Albumin helps maintain oncotic pressure, while some globulins are antibodies.
