Question
How can the circulatory system be described?
Multiple choice question.
- a mixed system (contains one open and one closed circuit)
- an open system
- a closed system
Solution
Understanding the Circulatory System
-
Overview of Circulatory System Types
The circulatory system can be categorized based on its structure and function. There are mainly two types: open and closed circulatory systems. -
Open Circulatory System
- In an open circulatory system, the blood is not confined exclusively to vessels. Instead, it flows freely through cavities in the body, making direct contact with tissues. This type is common in invertebrates like insects and crustaceans.
-
Closed Circulatory System
- Conversely, in a closed circulatory system, the blood circulates entirely within a network of vessels, allowing for more efficient transport of nutrients, gases, and waste products. This system is found in vertebrates, including humans.
-
Mixed System
- While both open and closed systems exist, the human circulatory system is classified as a closed circulatory system. It features a complex network of arteries, veins, and capillaries that ensure the efficient movement of blood throughout the body.
Final Answer
The correct answer to the question is:
a closed system.
