Chapter 7 & 9 Quiz

Which of the following provides the best example of the parts of a system working together to achieve a specific function?

• Specialized cells in a plant's leaf open and close in response to changing conditions
• Red blood cells are capable of transporting oxygen because of their chemical make up
• Salivary glands in the mouth, the stomach, the pancreas, and the small intestine secrete chemicals that break down nutrients.
• Animals that prey on other animals require the ability to move in their environment

Which body system is responsible for the excretion of waste products from the body?

• Respiratory System
• Circulatory System
• Excretory System
• Skeletal System

How do red blood cells contribute to the process of respiration in the human body?

• Red blood cells produce oxygen during respiration.
• Red blood cells transport carbon dioxide to the lungs.
• Red blood cells carry oxygen from the lungs to the body's cells.
• Red blood cells remove waste products from the body's cells.

What is one way the respiratory system and circulatory system work together?

• The respiratory system allows the body to breathe in oxygen and the circulatory system transports the oxygen to the cells in the body.
• The respiratory system allows the body to take in food and the circulatory system transports the nutrients through the body
• The circulatory system circulates nutrients, and the respiratory system gets rid of all the leftover waste.
• The circulatory system pumps blood through the heart and the respiratory system transports blood through the body.

Which of the following statements is true about the human body?

• The body is a system of isolated cells.
• The body is a system of unrelated subsystems.
• The body is a system of interacting subsystems.
• The body is a system of conflicting subsystems.

Which body system is responsible for breaking down food and absorbing nutrients?

• Digestive system
• Respiratory system
• Nervous system
• Excretory System

How do the nervous system and the muscular system work together?

• The nervous system sends signals to the muscles, causing them to contract and move the body.
• The nervous system provides the energy that muscles need to move.
• The muscular system send signals to the brain to make it work.
• The muscular system supplies the strength the brain needs to send signals.

What happens when mechanoreceptor cells in the ears detect a loud noise?

• Brain receives message to squint or shield eyes
• Brain receives message to remove hand from surface
• Brain receives message to cover ears or move away
• Brain receives message of enjoyment or desire for more

Which sensory receptors respond to a hot surface, and what message do they send to the brain?

• Photoreceptor respond to the hot surface by sending a message to the brain to stop looking at the hot surface
• Mechanoreceptors respond to the hot surface by telling the brain to scream
• Taste buds respond to the hot surface by sending a message to the brain to taste the hot surface again
• Thermoreceptor cells send a message to the brain to remove the hand from the hot surface

What happens when taste bud cells on the tongue detect a sweet taste?

• Brain receives a message of enjoyment
• Brain receives a message to spit the sweet food out
• Brain received no messages
• Brain sends message to squint eyes
