Answer:
1. Brain
Importance:
The brain is the body’s control center. It forms the core of the central nervous system by creating, sending, and processing nerve impulses, thoughts, emotions, physical sensations, and more.
2. Heart
Importance:
The heart is the most important organ of the circulatory system, which helps deliver blood to the body. It works with the lungs to add oxygen to the blood and pump this freshly oxygenated blood through the blood vessels and around the body.
3. Lungs
Importance:
The lungs work with the heart to oxygenate the blood. They do this by filtering the air a person breathes, then removing excess carbon dioxide in exchange for oxygen.
4. Liver
Importance:
The liver is the most important organ of the metabolic system. It helps convert nutrients into usable substances, detoxify certain substances, and filter blood coming from the digestive tract through a vein before it joins venous blood flow from other parts of the body. Oxygenated blood reaches the liver via an artery.
5. Kidneys
Importance:
The kidneys are a pair of bean-shaped organs, and each is about the size of a fist. They are located on either side of the back, protected inside of the lower part of the rib cage. They help filter blood and remove waste from the body.
