Yes, all animals have a nervous system of some kind. The nervous system includes the brain, and the brain allows you to see, touch, taste, smell, and hear things.

Animals have blood vessels and veins. Plants also have veins, but their veins carry water and animal veins carry blood.

Multicellular organisms are living things that are made up of many cells. [Accept any examples of multicellular organisms.]

Multicellular organisms need food and water to stay alive. They also need the various parts of their body to work together to keep them healthy.

When we eat something, food travels through our digestive system, which includes our mouth, stomach, intestines, and other organs. After food is digested, our bodies use it for energy and to help us stay healthy. We eliminate food we don’t need as waste through our excretory system.

Plants have different parts that need to work together, but they are different from animal parts. Plants get their energy and make their food using the Sun, and animals need to eat to get energy.

Our body is made of cells, cells work together to form tissue, tissues make up organs, organs make up our body’s subsystems, and all the subsystems work together to keep our body system alive and healthy.

Our sense receptors are found in our eyes, ears, tongue, skin, and nose. We need sense receptors for our various senses to work. They are also part of the nervous system.

I think we take medicine, like aspirin, to trick out nerves into not feeling pain.

The nervous system was also affected because the electrode was on the skin, so I think the impulse traveled through the nerves on our skin to the muscle to make it move.
