System Functions
This body system is responsible for transporting oxygen, nutrients, and waste throughout the body.
What is the circulatory system?
These two systems work together to allow your body to move.
What are the muscular and skeletal systems?
This is any change in the environment that causes a reaction in the body.
What is a stimulus?
This is the basic unit of structure and function in all living things.
What is a cell?
These cells attack and destroy infected body cells.
What are T-cells?
This system controls the body using electrical signals from the brain.
What is the nervous system?
The respiratory system and this system work together to deliver oxygen to cells.
What is the circulatory system?
This type of neuron carries messages from the sense organs to the brain and spinal cord.
What is a sensory neuron?
A group of similar cells working together to perform a specific job is called this.
What is a tissue?
These proteins help identify and neutralize foreign invaders.
What are antibodies?
This system breaks down food so the body can absorb nutrients.
What is the digestive system?
The nervous system and this system work together to respond to stress using hormones like adrenaline.
What is the endocrine system?
This type of neuron carries signals from the brain or spinal cord to muscles or glands.
What is a motor neuron?
Different tissues working together to perform a specific function form this.
What is an organ?
This type of immunity develops after getting sick or receiving a vaccine.
What is active immunity?
This system allows you to breathe in oxygen and remove carbon dioxide.
What is the respiratory system?
The digestive system absorbs nutrients that are transported by this system.
What is the circulatory system?
This neuron connects sensory neurons to motor neurons in the spinal cord and brain.
What is an interneuron?
A group of organs that work together to perform a major body function is called this.
What is an organ system?
This type of immunity is temporary and occurs when antibodies are given to a person.
What is passive immunity?
This system provides structure and support and works closely with muscles for movement.
What is the skeletal system?
The immune system relies on white blood cells that travel through this system.
What is the circulatory system?
These white blood cells produce antibodies to fight specific pathogens.
What are B-cells?
This is the single fertilized cell formed when a sperm and egg combine.
What is a zygote?
This type of white blood cell “eats” pathogens through phagocytosis.
What is a macrophage?
