Exploring the Human Body Systems

During a biology class, Carleigh and Logan were discussing the functions of different body systems. Carleigh said the main function of the respiratory system is to pump blood throughout the body, but Logan disagreed. According to Logan, what is the main function of the respiratory system?

• To pump blood throughout the body

• To digest food

• To exchange oxygen and carbon dioxide

• To control body movements

During a biology class, Saad and Logan were discussing about the human body. Saad said that the heart is primarily responsible for the digestion of food. Logan disagreed and said it's the stomach. Who is correct?

• Saad

• Logan

• Both are correct

• None of them are correct

During a biology class, Ethan was asked how the body transports oxygen and nutrients to its cells. He thought for a moment and then answered. What did he say?

• The body uses nerves to transport oxygen and nutrients.

• The body uses muscles to transport oxygen and nutrients.

• The body uses blood to transport oxygen and nutrients.

• Air is used to transport oxygen and nutrients to the body's cells.

During a biology class, Jiaxin was asked to identify the control center of the entire body in a human diagram. What should Jiaxin point to?

• Spinal cord

• Nerves

• Brain

• Eyes

Dex and Ruby are playing in the park. Dex says that the main function of the skeletal system is to produce hormones, while Ruby thinks it's to provide support and protection for the body. Who is correct?

• Dex: To produce hormones

• Ruby: To absorb nutrients

• Ruby: To provide support and protection for the body

• Dex: To contract and cause movement

During a biology class, Tyler and Toby were discussing about the human body. Tyler mentioned that there is a type of muscle that is found only in the heart. Can you help Toby identify what Tyler was referring to?

• Smooth muscle

• Skeletal muscle

• Cardiac muscle

• Connective tissue

During a biology class experiment, Cameron and Logan were studying the interaction between the respiratory and circulatory systems. How does the respiratory system work with the circulatory system in this context?

• It helps Logan's body circulate blood during the experiment.

• It provides oxygen to Cameron's blood and removes carbon dioxide during the experiment.

• It digests nutrients to feed Ruby's blood cells during the experiment.

• It sends electrical signals to pump Carleigh's heart during the experiment.

During a biology class, Tyler, Paisyn, and Cameron were discussing the digestive system. They were curious about the role of the small intestine. Kennon suggested that it might be to store undigested food, Carleigh thought it might be to pump digestive enzymes, but Tyler believed it was to absorb nutrients from digested food. Cameron, on the other hand, thought it was to filter blood. Who among them is correct?

• Kennon's suggestion: To store undigested food

• Carleigh's thought: To pump digestive enzymes

• Tyler's belief: To absorb nutrients from digested food

• Cameron's thought: To filter blood

During a science fair, Dex and Toby were discussing about the human body. Dex said that the skeletal system coordinates the body's response to changes in its internal and external environment. Toby disagreed and said it was the nervous system. Ethan, who was listening to their conversation, said it was the muscular system. Ruby, who was also part of the conversation, thought it was the circulatory system. Who among them is correct?

• Dex (Skeletal system)

• Toby (Nervous system)

• Ethan (Muscular system)

• Ruby (Circulatory system)

During a biology class, Saad and Ethan were discussing the muscular system. Saad said that the function of tendons is to connect muscles to bones. Is Saad correct?

• Yes, tendons connect muscles to bones

• No, tendons connect bones to bones

• No, tendons help in the digestion of food

• No, tendons carry oxygen to the muscles
