interacting systems
100
The system that is ALWAYS involved in maintaining homeostasis.
The nervous system
100
Which system is responsible for waste removal in the body. 💩💩💩
The excretory system
100
Which of the following provides the best evidence that the circulatory system and the respiratory system work together to carry out their functions?
- Nutrients are absorbed into the blood from the intestines
- Lungs expand and contract through movements of the diaphragm.
- New red blood cells are generated in the marrow of bones
- The blood carries gases exchanged in the lungs
The blood carries gases exchanged in the lungs (the alveoli in the 🫁 interact with the capillaries in the circulatory 🩸🩸🩸 system).
100
This body system breaks down our food and provides the nutrients our body needs to grow and maintain homeostasis.
The digestive system 👄
100
Name the two interacting systems :
food from breakfast is broken down into nutrients and then delivered to blood cells.
The digestive and circulatory systems
200
The system that works closely with the nervous system to maintain health/wellness. (HINT: the nervous system is QUICK to respond, while this system is slower)
The endocrine system
200
Which of the following best describes the function of this system?
- absorbing nutrients from food
- protecting the body from infection
- exchanging gases with the environment
- responding to stimuli in the environment
- exchanging gases with the environment
200
Which of the following correctly orders part of a human’s respiratory system from the least complex to the most complex
- cells → lungs → tissues
- cells → tissues → lungs
- lungs → tissues → cells
- tissues → lungs → cells
cells → tissues → lungs
200
This body system transports blood and nutrients throughout the body. 
The circulatory system 🩸🫀
200
The brain interprets a threatening stimuli from your surroundings and your heart beats faster!
The nervous and circulatory
300
What system regulates our 🩸blood sugar levels?
***700 pt. BONUS: what 2 hormones maintain blood sugar levels?
The endocrine system. Insulin: brings 🩸sugar ⬇️ and Glucagon brings 🩸 sugar ⬆️.
300
The terms gas exchange, diaphragm, and inhale are most closely associated with which system in the human body?
- circulatory
- digestive
- excretory
- respiratory
The respiratory system
300
The diagrams below show structures from the circulatory and respiratory systems.
Which statement below best summarizes how the two organ systems interact with one another?
- Muscles contract to move the bones and ligaments of the body.
- The brain sends messages through neurons to ensure the heart beats.
- The lungs take in oxygen from the environment and arteries circulate the oxygen through the body.
- The stomach extracts nutrients from food and the arteries circulate the nutrients through the body.
The lungs take in oxygen from the environment and arteries circulate the oxygen through the body.
300
This body system is a network of organs and tissues that help you exchange gases, INhaling oxygen and EXhaling carbon dioxide.
The respiratory system 🫁
300
Name the three body systems working together when you SEE a threat and your adrenal GLAND activates a HORMONE called cortisol to make your HEART beat faster.
The nervous, circulatory, and endocrine systems.
400
Name 3 examples of the human body maintaining homeostasis.
1) temperature 🌡️ regulation
2) blood pressure 🫀 regulation
3) water 💦 balance
400
Body systems work TOGETHER to maintain stability and homeostasis. What happens when there is DEstabilization in the body?
Answers may vary: When the body is NOT stable (or DEstabilized) it can lead to health issues, illness, or disease.
400
Veins and arteries are both blood vessels that carry blood. What is the difference between veins and arteries.
Veins carry blood toward your heart, arteries carry blood away from your heart.
AA= arteries/away
400
This body system DEFENDS the body from pathogens such as a virus, bacteria or fungus. 🛡️🛡️🛡️
The immune system
400
Name the two systems that interact when you exercise and your breathing rate increases, supplying more oxygen to your muscle cells.
The respiratory and circulatory systems.
500
Describe what happens when the body is in fight/flight response?
The nervous system 🧠 and endocrine system work together. The nervous system RAPIDLY responds while the endocrine system releases HORMONES (like adrenaline & cortisol) to sustain the response.
500
Which of the following accurately describes one part of the hierarchy (ORDER) of organization in living things?
- Tissues are made up of various cells
- Organs are made up of various organ systems
- Cells are made of various organs
- Tissues are made up of various organisms
Tissues are made up of various cells (cells are TINY and together they create tissue, which then makes up the organs.)
500
What body system is this?
The nervous system 🧠⚡(brain, nerves, neurotransmitters)
500
This body system regulates the body's hormones (chemical messengers found in glands).
The endocrine system
500
Name the body systems interacting: the pancreas secretes the hormone insulin to maintain blood sugar levels from breaking down food that fuels the body.
The endocrine and digestive systems.
