Transcript text: A white blood cell engulfing a bacterium is an example of blood functioning in
maintenance
communication
transportation
protection
Solution
The answer is the last one: protection.
Explanation for each option:
Maintenance: This option is incorrect because maintenance refers to the body's processes that keep it functioning properly, such as repairing tissues or regulating internal conditions. Engulfing a bacterium is not directly related to these processes.
Communication: This option is incorrect because communication in the context of blood typically involves signaling between cells or organs, such as through hormones or neurotransmitters. Engulfing a bacterium is not a form of communication.
Transportation: This option is incorrect because transportation in the blood refers to the movement of substances like oxygen, nutrients, and waste products throughout the body. Engulfing a bacterium is not related to transporting substances.
Protection: This option is correct because white blood cells play a crucial role in the immune system by protecting the body against infections. Engulfing a bacterium is a defensive action that helps to eliminate harmful pathogens, thus providing protection to the body.
