Circulatory System
What is the function of the circulatory system?
A. Communicate to other body subsystems
B. Transport to other body subsystems
C. Support other body subsystems
B. Transport to other body subsystems
What is the function of the respiratory system?
Gas exchange --> Provides body subsystems with oxygen and removes carbon dioxide
What is the function of the excretory system?
Regulate body temperature and maintain homeostasis in the body
Most basic unit of life
cell
How old is Bill Nye?

Where does gas exchange take place?
A. Bronchi
B. Bronchioles
C. Alveoli
C. Alveoli
Why do we sweat?
Excrete waste and regulate our body temperature
Highest level of organization of the body?
Human or Organism
How do cigarettes impact the respiratory system?
Kills cilia allowing dirt and mucus into the lungs, creates cancer cells, breaks down alveoli walls
What do red blood cells transport around the body to other body subsystems?
Nutrients, hormones, oxygen, carbon dioxide, waste
Name five parts of the respiratory system
Nose, Mouth, Trachea, Bronchi, Lungs, Alveoli, Bronchioles, diaphragm, larynx, pharynx
Name 6 parts of the excretory system
Skin, lungs, kidneys, bladder, liver, large intestine, ureters, urethra
What level of organism of the body is the Lung?
Organ
How does the digestive system work with the circulatory system to support the body?
The digestive system breaks down food energy for blood to transport
What do the arteries carry away from the heart?
Oxygenated blood
Can you live with just one lung?
Yes, if it is healthy!
What does the liver do to remove waste in the excretory system?
Uses special chemicals to clean the blood
What level of organization of the body is the excretory system?
Organ System
What two body systems are most important for humans to survive?
Circulatory System and Respiratory System
Why does your heart rate increase during exercise?
During exercise you are using energy and other body subsystems require an increase in oxygen and nutrients to properly function. Your heart rate increases as your heart pumps harder to transport more oxygen, nutrients, and carbon dioxide. Carbon dioxide is expelled from the lungs by the process of gas exchange in the alveoli.
What muscle allows us to inhale and exhale?
Diaphragm
What is the kidneys job for the excretory system?
Filter out waste from the blood
Name all levels of organization of the human body from smallest to largest in the respiratory system
Lung cell, lung tissue, lung, respiratory system, human
How does the circulatory system support the respiratory system in removing waste from the body?
The circulatory system transports the CO2 and the respiratory system expels the CO2 from the body
