1.
Controls the body
Correct Answer
D. Brain
Explanation
The brain controls the body's functions and processes. It is responsible for coordinating and regulating various bodily activities, including the functioning of the heart, skin, liver, and eyes. The brain sends signals to these organs and systems, allowing them to perform their respective functions. Without the brain, the body would not be able to function properly.
2.
Controls vision
Correct Answer
C. Eyes
Explanation
The correct answer is eyes because the eyes are responsible for controlling vision. The eyes receive light and convert it into electrical signals that are sent to the brain, which then processes and interprets the visual information. The other options listed, such as intestines, kidneys, liver, and skin, do not have a direct role in controlling vision.
3.
Circulates the blood
Correct Answer
B. Heart
Explanation
The heart circulates the blood throughout the body. It pumps oxygenated blood to all the organs and tissues, supplying them with the necessary nutrients and oxygen. It also carries away waste products and carbon dioxide from the cells. The heart plays a vital role in maintaining the overall functioning of the body by continuously pumping and circulating the blood.
4.
Excrete water and waste products
Correct Answer
E. Kidneys
Explanation
The kidneys are responsible for excreting water and waste products from the body. They filter the blood, removing excess water, toxins, and waste products, which are then excreted as urine. The other options mentioned, such as glands, liver, and stomach, do play important roles in the body, but they are not primarily responsible for excreting water and waste products.
5.
Supply oxygen to the blood
Correct Answer
A. Lungs
Explanation
The lungs supply oxygen to the blood. They are responsible for the exchange of gases, taking in oxygen from the air we breathe and releasing carbon dioxide. Oxygenated blood is then transported to the rest of the body through the circulatory system, providing oxygen to the brain, eyes, and other organs.
6.
Removes toxic products of digestion
Correct Answer
D. Liver
Explanation
The liver is responsible for removing toxic products of digestion from the body. It detoxifies harmful substances, such as alcohol and drugs, and converts them into less harmful forms that can be eliminated. Additionally, the liver produces bile, which helps in the digestion and absorption of fats. It also plays a role in regulating blood sugar levels, storing vitamins and minerals, and producing important proteins for blood clotting. Therefore, the liver is vital for maintaining overall health and detoxification processes in the body.
7.
Forms external protective covering
Correct Answer
E. Skin
Explanation
The skin forms an external protective covering for the body. It acts as a barrier against harmful substances, microorganisms, and UV radiation. It helps regulate body temperature, prevents excessive water loss, and provides sensory information through nerve endings. The skin also plays a role in the production of vitamin D and helps in excreting waste products through sweat. Overall, the skin serves as a vital protective layer for the underlying tissues and organs of the body.
