Name that System
I contain the heart, blood vessels, and blood. My main job is transportation throughout the body
What is the cardiovascular system?
My primary job is to bring oxygen into the body and remove carbon dioxide.
What is the respiratory system
Which two systems work together to get oxygen from the air into the bloodstream and then deliver it to body tissues?
What are the respiratory and cardiovascular systems?
What term describes the body's ability to maintain a relatively stable internal environment?
What is homeostasis?
Name one behavior that can help protect both the respiratory and cardiovascular systems.
Avoid tobacco/nicotine products
I include the brain, spinal cord, and nerves. I receive information and coordinate rapid responses.
What is the nervous system
I provide the body's framework, protect organs, store minerals, and work with muscles to create movement.
What is the skeletal system?
The digestive system absorbs nutrients from food. Which system transports many of those nutrients throughout the body?
What is the cardiovascular system?
Your body temperature rises while exercising. Your body begins sweating to help cool itself. Is this an example of homeostasis?
yes
Regular physical activity does more than strengthen muscles. Name two other body systems that can benefit from regular exercise.
I include the skin, hair, nails, and glands. I help protect the body and regulate temperature
What is the integumentary system
I break food down into smaller substances and absorb nutrients that the body can use.
What is the digestive system?
During exercise, your muscles need more oxygen. One system gets oxygen into the lungs while another transports it to working muscles. Identify both.
Respiratory and cardiovascular systems.
Why does maintaining a stable internal temperature matter to the body?
Because cells and organs function best within appropriate internal conditions.
Why does your heart beat faster during exercise?
To increase blood flow and help deliver more oxygen and nutrients to working tissues while removing wastes.
I contain organs that filter the blood and help control the body's water and electrolyte balance.
What is the urinary system
The tiny structures inside the lungs where oxygen enters the blood and carbon dioxide leaves it are called what?
What are the alveoli?
Your brain tells your skeletal muscles when and how to move. Which two systems are communicating in this example?
Nervous and muscular systems.
A student becomes dehydrated. Which organ system becomes especially important for regulating the body's water balance?
What is the urinary system?
During vigorous exercise, why does breathing become faster?
The body needs more oxygen and needs to remove carbon dioxide more rapidly.
I release chemical messengers that travel through the bloodstream to regulate processes such as growth, metabolism, and stress responses.
What is the endocrine system?
The kidneys do more than remove waste. Name two important conditions they help regulate.
Water balance, electrolyte balance, and acid-base balance
A student runs outside on a hot day. Their heart rate increases, breathing becomes faster, their muscles use more oxygen, and they begin sweating. Name four different body systems involved.
Explain why homeostasis requires multiple body systems instead of one system working alone.
Body systems are interconnected. They communicate and work together to maintain stable internal conditions.
A student says, "Exercise only affects the muscular system." Explain why that statement is incorrect.
Exercise requires multiple systems to work together. The cardiovascular system transports oxygen, the respiratory system exchanges gases, the nervous system coordinates movement, the muscular system produces movement, and the integumentary system helps regulate temperature through sweating.
