Answer:
Step-by-step explanation:
Animal Cell:
Example: Neuron (nerve cell)
Function: Neurons are specialized cells that transmit electrical signals, allowing communication within the nervous system. They play a crucial role in transmitting information between different parts of the body.
Tissue:
Example: Muscle Tissue
Function: Muscle tissue is responsible for movement and generating force. There are three types of muscle tissue: skeletal muscle (voluntary movement), smooth muscle (involuntary movement of internal organs), and cardiac muscle (found in the heart).
Organ:
Example: Heart
Function: The heart is a muscular organ that pumps blood throughout the circulatory system. It ensures that oxygenated blood is distributed to the body's tissues and organs and deoxygenated blood is returned to the lungs for oxygenation.
System:
Example: Digestive System
Function: The digestive system is responsible for breaking down food into nutrients that can be absorbed by the body. It includes organs such as the mouth, esophagus, stomach, small intestine, large intestine, and more, which work together to digest and absorb nutrients.
