Examples of organs in animals may include the heart, lungs, liver, brain, and stomach. Examples of organs in plants may include the leaves, roots, stems, flowers, and seeds.
Not all animals have a nervous system, as some very simple organisms do not possess one. The nervous system is responsible for receiving and interpreting sensory information, coordinating bodily functions, and sending signals to the muscles to allow movement.
An example of a structure that is similar in plants and animals is the circulatory system. Both plants and animals have systems for transporting nutrients and materials throughout their bodies. In animals, this is done through the cardiovascular system, while in plants it is done through the vascular system.
Multicellular organisms are organisms made up of more than one cell. Examples include humans, plants, animals, fungi, and some algae. The cells in multicellular organisms work together to perform specific functions in order to keep the organism alive.
After watching the video, the various parts of the body work together when we eat something by the digestive system breaking down the food into nutrients, which are then absorbed by the circulatory system and distributed to cells throughout the body to provide energy.
Plant and animal structures are similar in that they both have systems for transporting nutrients, obtaining energy, and reproducing. However, they are different in their specific structures and functions, such as the type of cells they are made up of and how they reproduce.
The human body system is organized into different systems, such as the skeletal system, muscular system, nervous system, circulatory system, respiratory system, and digestive system, each with specific functions that work together to maintain homeostasis.
Sense receptors in the human body are found in the skin, eyes, ears, nose, and tongue, and allow us to detect external stimuli such as touch, light, sound, smell, and taste.
One way we can "trick" our nervous system is by taking pain medication for a headache, which interferes with the transmission of pain signals to the brain. Besides the muscular system, the nervous system is affected by the electrical impulse used to make a muscle move, as it is responsible for transmitting the signal from the brain to the muscles for movement.
