which two statements explains how a earthworms organ system help provide its cells with oxygen?
a. the nervous system removes oxygen from the body
**b. the curatorial system carries oxygen to different parts of the body.
**c. the respiratory system brings oxygen into the body
d. the digestive system delivers oxygen to the blood
The correct statements that explain how an earthworm's organ system helps provide its cells with oxygen are:
b. The circulatory system carries oxygen to different parts of the body.
c. The respiratory system brings oxygen into the body.
To determine which two statements explain how an earthworm's organ system helps provide its cells with oxygen, we can examine each option:
a. The nervous system removes oxygen from the body:
This statement is incorrect. The primary function of the nervous system is to transmit signals to and from various parts of the body, such as coordinating movement and regulating bodily functions. It is not directly involved in the transport or removal of oxygen.
b. The circulatory system carries oxygen to different parts of the body:
This statement is correct. The circulatory system, or cardiovascular system, is responsible for transporting oxygen-rich blood to different tissues and organs in the body. In earthworms, this system helps deliver oxygen to the cells.
c. The respiratory system brings oxygen into the body:
This statement is correct. The respiratory system plays a crucial role in the intake of oxygen and the release of carbon dioxide. In earthworms, respiration occurs through their skin, which absorbs oxygen from the surrounding environment.
d. The digestive system delivers oxygen to the blood:
This statement is incorrect. The primary function of the digestive system is to process food and absorb nutrients. It does not directly facilitate the delivery of oxygen to the cells.
Based on the explanations above, the two correct statements are b. The circulatory system carries oxygen to different parts of the body and c. The respiratory system brings oxygen into the body.
