Let's go through each question one by one and solve them with explanations:
---
1. What is the system responsible for taking in oxygen and removing carbon dioxide from the body?
Answer: b. Respiratory
✔ Explanation: The respiratory system includes the lungs, trachea, and other airways. It brings oxygen into the body and removes carbon dioxide, a waste product of cellular respiration.
---
2. This system is responsible for breaking down food so that nutrients may enter the bloodstream.
Answer: c. digestive
✔ Explanation: The digestive system breaks down food into smaller molecules (like glucose, amino acids) that can be absorbed into the bloodstream through the small intestine.
---
3. Which of the following systems would consist of glands that produce hormones?
Answer: 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 bodily functions.
---
4. Which body system performs a function similar to that of the vascular system of a plant?
Answer: a. Circulatory
✔ Explanation: In plants, the vascular system (xylem and phloem) transports water, nutrients, and sugars. Similarly, the human circulatory system transports blood, oxygen, nutrients, and waste products throughout the body.
---
5. Which body system includes the kidneys and bladder?
Answer: b. Urinary
✔ Explanation: The urinary system filters blood, removes waste, and produces urine. Key organs include the kidneys, ureters, bladder, and urethra.
---
6. Which system protects and supports; stores minerals?
Answer: a. Skeletal
✔ Explanation: The skeletal system provides structural support, protects internal organs, 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?
Answer: d. Integumentary
✔ Explanation: The integumentary system includes the skin, hair, nails, and associated glands. It acts as a barrier against pathogens, UV radiation, and physical damage.
---
8. Which body system tells you when to reach for and catch a falling book?
Answer: c. nervous
✔ Explanation: The nervous system detects stimuli (like seeing a falling book), processes information, and sends signals to muscles to react quickly — this is reflexive coordination.
---
9. Which system enables movement of the body?
Answer: a. Muscular
✔ Explanation: The muscular system, working with the skeletal system, allows voluntary and involuntary movements. Muscles contract to move bones.
---
10. Which system is made up of an intricate network of vessels, nodes, and organs that we can find all around the human body?
Answer: d. Lymphatic
✔ Explanation: The lymphatic system includes lymph vessels, lymph nodes, spleen, and thymus. It helps in immune defense and returns excess fluid to the bloodstream.
---
1. b. Respiratory
2. c. digestive
3. c. endocrine system
4. a. Circulatory
5. b. Urinary
6. a. Skeletal
7. d. Integumentary
8. c. nervous
9. a. Muscular
10. d. Lymphatic
