Here's the complete solution to the “Body Systems” worksheet, with explanations for each answer:
---
1. What is the system responsible for taking in oxygen and removing carbon dioxide from the body?
✔ b. Respiratory
*Explanation:* The respiratory system (lungs, trachea, bronchi) exchanges gases — takes in oxygen and expels carbon dioxide — through breathing.
---
2. This system is responsible for breaking down food so that nutrients may enter the blood stream.
✔ c. Digestive
*Explanation:* The digestive system (stomach, intestines, liver, pancreas) breaks down food into absorbable nutrients that enter the bloodstream via the small intestine.
---
3. Which of the following systems would consist of glands with tissues that produce hormones?
✔ c. endocrine system
*Explanation:* The endocrine system includes glands like the pituitary, thyroid, and adrenal glands that secrete hormones directly into the bloodstream to regulate body functions.
---
4. Which body system performs a function similar to that of the vascular system of a plant?
✔ a. Circulatory
*Explanation:* Plants have a vascular system (xylem and phloem) that transports water, minerals, and food. In humans, the circulatory system (heart, blood vessels, blood) transports oxygen, nutrients, and waste — performing a similar transport function.
---
5. Which body system includes the kidneys and bladder?
✔ b. Urinary
*Explanation:* The urinary system filters blood, removes waste, and produces urine. Key organs include the kidneys (filter), ureters, bladder (stores urine), and urethra.
---
6. Which system protects and supports; stores minerals?
✔ a. Skeletal
*Explanation:* The skeletal system provides structural support, protects internal organs (like the skull protecting the brain), and stores minerals like calcium and phosphorus in bones.
---
7. What body system forms the external surface of the body and provides protection from dehydration, environmental chemicals, and impacts?
✔ d. Integumentary
*Explanation:* The integumentary system includes the skin, hair, and nails. It acts as a barrier against dehydration, UV rays, chemicals, and physical injury.
---
8. Which body system tells you when to reach for and catch a falling book?
✔ c. nervous
*Explanation:* The nervous system (brain, spinal cord, nerves) processes sensory input (seeing the book fall) and sends motor signals to muscles to react — like reaching out to catch it.
---
9. Which system enables movement of the body?
✔ a. Muscular
*Explanation:* The muscular system contracts and relaxes to move bones and joints, enabling voluntary movements (like walking) and involuntary ones (like heartbeat).
---
10. Which system is made up of an intricate network of vessels, nodes, and organs that we can find all around the human body?
✔ d. Lymphatic
*Explanation:* The lymphatic system includes lymph vessels, lymph nodes, spleen, and thymus. It helps fight infection and drains excess fluid from tissues — found throughout the body.
