Do You Know The Human Organ Systems? - Quiz

Are you an aspiring medical or veterinary student? Do you need to brush up on your organ systems? Take this quiz to see how much you know about human organ systems.

Questions and Answers

1.

The lungs are a part of the ________ system.
- A.
  
  Ciculatory
- B.
  
  Respiratory
- C.
  
  Nervous
- D.
  
  Skeletal
Correct Answer
B. Respiratory

Explanation
The correct answer is "Respiratory" because the lungs are an essential organ in the respiratory system. The respiratory system is responsible for the exchange of oxygen and carbon dioxide in the body. The lungs help in the process of breathing, taking in oxygen from the air and releasing carbon dioxide. Therefore, the lungs play a crucial role in the respiratory system.

The _______ is a part of the _______ system.
- A.
  
  Lungs, circulatory
- B.
  
  Testes, muscular
- C.
  
  Kidney, excretory
- D.
  
  Intestines, nervous
Correct Answer
C. Kidney, excretory

Explanation
The kidney is a part of the excretory system. The excretory system is responsible for removing waste and toxins from the body, and the kidney plays a crucial role in this process. It filters waste products from the blood and produces urine, which is then eliminated from the body. Therefore, the kidney is an essential component of the excretory system.

The circulatory system's job is to _______
- A.
  
  Transport nutrients and oxygen
- B.
  
  Cleanse the body
- C.
  
  Absorb nutrients
- D.
  
  Give the body its shape
Correct Answer
A. Transport nutrients and oxygen

Explanation
The circulatory system is responsible for transporting nutrients and oxygen throughout the body. It consists of the heart, blood vessels, and blood. Oxygen is carried by the red blood cells and delivered to the body's tissues, while nutrients from the digestive system are also transported through the blood. This process ensures that all cells receive the necessary nutrients and oxygen for their proper functioning.

Which organ system protects the internal organs?
- A.
  
  Muscular
- B.
  
  Skeletal
- C.
  
  Nervous
- D.
  
  Respiratory
Correct Answer
B. Skeletal

Explanation
The skeletal system protects the internal organs. The bones of the skeleton provide a rigid framework that surrounds and supports the organs, keeping them safe from external forces. Additionally, the skull protects the brain, the ribcage protects the heart and lungs, and the spinal column protects the spinal cord. Overall, the skeletal system plays a crucial role in safeguarding the internal organs.

The ovaries are part of the _________ system.
- A.
  
  Lymphatic
- B.
  
  Urinary
- C.
  
  Endocrine
- D.
  
  Reproductive
Correct Answer
D. Reproductive

Explanation
The ovaries are part of the reproductive system because they are responsible for producing and releasing eggs (ova) for fertilization. They also produce hormones such as estrogen and progesterone, which are essential for regulating the menstrual cycle and maintaining pregnancy. The reproductive system includes all the organs and structures involved in the production, transport, and fertilization of gametes (eggs and sperm) and the development of offspring.

6.

Hormones are produced and regulated by the regulated _________ system.
- A.
  
  Reproductive
- B.
  
  Endocrine
- C.
  
  Urinary
- D.
  
  Lymphatic
Correct Answer
B. Endocrine

Explanation
The correct answer is Endocrine. Hormones are produced and regulated by the endocrine system. This system consists of glands that secrete hormones directly into the bloodstream to regulate various bodily functions and maintain homeostasis. The endocrine system plays a crucial role in growth, metabolism, reproduction, and overall body functioning.

7.

Which organ system allows movement?
- A.
  
  Muscular
- B.
  
  Skeletal
- C.
  
  Nervous
Correct Answer
A. Muscular

Explanation
The muscular system allows movement in the body. Muscles are responsible for generating force and enabling the body to move and perform various activities. They work in coordination with the skeletal system, which provides the structure and support for the movement, and the nervous system, which controls and coordinates the muscle contractions. Together, these three systems allow for voluntary and involuntary movement throughout the body.

Rate this question:
8.

Which of the following is NOT part of the respiratory system?
- A.
  
  Lungs
- B.
  
  Adrenal gland
- C.
  
  Bronchioles
- D.
  
  Alveoli
Correct Answer
B. Adrenal gland

Explanation
The adrenal gland is not part of the respiratory system. It is an endocrine gland located on top of the kidneys and is responsible for producing hormones such as adrenaline. The respiratory system, on the other hand, is composed of organs involved in the process of breathing, including the lungs, bronchioles, and alveoli.
