The reproductive system also plays a role in sexual behavior and attraction.
7.
Controls immune response and fights disease.
Correct Answer
E. Immune
Explanation
The immune system is responsible for controlling immune responses and fighting against diseases. It plays a crucial role in protecting the body from harmful pathogens and foreign substances. It consists of various specialized cells, tissues, and organs that work together to identify and eliminate harmful invaders. The immune system is essential for maintaining overall health and preventing infections and diseases.
8.
Protects, regulates temperature, & prevents water loss.
Correct Answer
C. Integumentary
Explanation
The integumentary system is responsible for protecting the body from external factors, regulating body temperature, and preventing water loss. It consists of the skin, hair, nails, and glands. The skin acts as a barrier against pathogens and harmful substances, while also helping to regulate body temperature through sweat production and blood vessel constriction or dilation. Additionally, the skin contains oil glands that help to prevent water loss by keeping the skin hydrated. Therefore, the integumentary system is the correct answer.
9.
Bones, ligaments, & tendons.
Correct Answer
B. Skeletal
Explanation
The correct answer is skeletal because bones, ligaments, and tendons are all part of the skeletal system. The skeletal system provides support and structure to the body, protects internal organs, and allows for movement. Bones are connected to each other by ligaments, which are tough bands of tissue, and tendons attach muscles to bones. Together, these components make up the skeletal system, which is responsible for the body's framework and locomotion.
10.
Smooth muscle, skeletal muscle, cardiac muscle.
Correct Answer
A. Muscular
Explanation
The given correct answer is "muscular" because smooth muscle, skeletal muscle, and cardiac muscle are all types of muscles found in the body. Smooth muscle is found in the walls of organs and blood vessels, skeletal muscle is attached to bones and helps with movement, and cardiac muscle is found in the heart. Therefore, the common characteristic among these three types of muscle is that they are all muscular tissues.
11.
Mouth, esophagus, stomach, & intestine.
Correct Answer
A. Digestive
Explanation
The given answer, "digestive," is the correct answer because the sequence of body parts mentioned - mouth, esophagus, stomach, and intestine - are all part of the digestive system. These organs work together to break down food, absorb nutrients, and eliminate waste. The digestive system is responsible for the digestion and absorption of nutrients from the food we consume.
12.
Heart, veins, arteries, blood.
Correct Answer
C. Circulatory
Explanation
The given options heart, veins, arteries, and blood are all components of the circulatory system. The circulatory system is responsible for transporting oxygen, nutrients, hormones, and other substances throughout the body. It consists of the heart, which pumps the blood, the veins and arteries, which carry the blood, and the blood itself, which carries all the necessary substances. Therefore, the correct answer is circulatory.
13.
Nose, lungs, trachea (windpipe)
Correct Answer
B. Respiratory
Explanation
The given answer "respiratory" is correct because the organs mentioned - nose, lungs, and trachea - are all part of the respiratory system. The respiratory system is responsible for the exchange of oxygen and carbon dioxide in the body. The nose acts as an entry point for air, the trachea carries air to the lungs, and the lungs are where the exchange of gases takes place. Therefore, these organs are all related to the respiratory system.
14.
Bladder, rectum, anus.
Correct Answer
C. Excretory
Explanation
The given answer "excretory" is correct because the organs listed (bladder, rectum, anus) are all part of the excretory system. The excretory system is responsible for removing waste and toxins from the body, and these organs play a role in the elimination of waste products. The bladder stores urine, the rectum stores solid waste before it is eliminated through the anus. Therefore, these organs are all involved in the excretion process, making "excretory" the correct answer.
15.
Brain & nerves.
Correct Answer
A. Nervous
Explanation
The term "brain & nerves" refers to the nervous system, which is responsible for transmitting signals between different parts of the body and coordinating body functions. The nervous system includes the brain, spinal cord, and nerves. It controls both voluntary actions, such as movement, and involuntary actions, such as breathing and heartbeat. Therefore, the correct answer is "nervous" as it accurately represents the system associated with the brain and nerves.
16.
White blood cells, antibodies
Correct Answer
A. Immune
Explanation
The correct answer is immune because white blood cells and antibodies are both components of the immune system. White blood cells are responsible for fighting off infections and foreign substances in the body, while antibodies are proteins produced by white blood cells to specifically target and neutralize pathogens. Therefore, the presence of white blood cells and antibodies indicates an immune response. The other options (integumentary and nervous) are not directly related to the immune system.
