Step-by-step solution for: Systems In The Human Body - Middle School Science
To solve the problem, we need to match each description with the correct system in the human body. Let's go through each statement and identify the corresponding system:
---
1. Defends the body against pathogenic viruses that may endanger the body.
- Answer: Immune system
- Explanation: The immune system is responsible for defending the body against pathogens such as viruses, bacteria, and other harmful substances.
---
2. The system where the kidneys filter blood.
- Answer: Urinary system
- Explanation: The kidneys are part of the urinary system, which filters waste products from the blood and regulates fluid balance in the body.
---
3. Collects and processes information from the senses, perceives the brain and tells the muscles to contract to cause physical action.
- Answer: Nervous system
- Explanation: The nervous system includes the brain, spinal cord, and nerves, which collect sensory information, process it, and send signals to muscles to cause movement or other actions.
---
4. Includes glandular and chemical processes that provide nutrients via the mouth, esophagus, stomach, and intestines.
- Answer: Digestive system
- Explanation: The digestive system breaks down food into nutrients that can be absorbed by the body. It includes organs like the mouth, esophagus, stomach, and intestines.
---
5. Eliminates waste from the body.
- Answer: Urinary system
- Explanation: The urinary system removes waste products (such as urea) from the blood and expels them from the body as urine.
---
6. Bones supporting the body and its organs.
- Answer: Skeletal system
- Explanation: The skeletal system provides structural support to the body, protects internal organs, and allows for movement.
---
7. The sex organs required for the production of offspring.
- Answer: Reproductive system
- Explanation: The reproductive system includes the sex organs (e.g., ovaries, testes) that produce gametes (eggs and sperm) and are essential for reproduction.
---
8. Circulates blood around the body via the heart, arteries, and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away.
- Answer: Circulatory system
- Explanation: The circulatory system, consisting of the heart, blood vessels, and blood, transports oxygen, nutrients, hormones, and waste products throughout the body.
---
9. Enables the body to move using muscles.
- Answer: Muscular system
- Explanation: The muscular system consists of muscles that allow the body to move, maintain posture, and generate heat.
---
10. Skin, hair, nails, sweat and other exocrine glands.
- Answer: Integumentary system (not listed in the options)
- Explanation: The integumentary system includes the skin, hair, nails, and sweat glands, which protect the body, regulate temperature, and excrete waste.
---
11. The lungs and the trachea that bring air into the body.
- Answer: Respiratory system
- Explanation: The respiratory system includes the lungs and trachea, which facilitate breathing by bringing oxygen into the body and removing carbon dioxide.
---
12. The system comprising a network of lymphatic vessels that carry a clear fluid called lymph.
- Answer: Lymphatic system
- Explanation: The lymphatic system transports lymph (a clear fluid containing white blood cells) throughout the body, helps maintain fluid balance, and plays a role in immunity.
---
13. Provides chemical communications within the body using hormones.
- Answer: Endocrine system
- Explanation: The endocrine system produces hormones that regulate various bodily functions, such as growth, metabolism, and reproduction.
