Where is the difference between pulmonary and systemic circulation?
The pulmonary circuit is the blood flow from the heart to the lungs and back to the heart. The systemic circuit is the blood flow from the heart to the body and back to the heart.
The pulmonary circuit is the blood flow from the heart to the body and back to the heart. The systemic circuit is the blood flow from the heart to the lungs and back to the heart.
Both pulmonary and systemic circuits carry blood only to the lungs.
Both pulmonary and systemic circuits carry blood only to the body.
What happens to your heart rate as you exercise?
When you exercise your body requires energy. You need oxygen to produce energy and your body makes carbon dioxide as waste in this process. The blood and heart are responsible for moving these gases to and from the lungs. Your heart rate increases when you exercise to keep up with the increasing demands for oxygen and to rid the body of the increasing amount of CO2 produced.
Your heart rate decreases when you exercise because your body needs less oxygen and produces less carbon dioxide.
Your heart rate remains the same during exercise because your body does not require any changes in oxygen or carbon dioxide levels.
Your heart rate stops temporarily during exercise to allow your body to rest.
What gas does the respiratory and cardiovascular systems work together to supply to all the cells in the body?
Oxygen
Carbon Dioxide
Nitrogen
Hydrogen
This muscle plays a major role in inhaling and exhaling:
The diaphragm
The biceps
The quadriceps
The deltoid
Does the respiratory eliminate waste? Explain
Yes the respiratory system is responsible for eliminating carbon dioxide which is cellular waste produced during cellular respiration.
No, the respiratory system only supplies oxygen and does not eliminate any waste.
No, the respiratory system eliminates only water vapor, not any waste products.
No, the respiratory system is responsible for digesting food, not eliminating waste.
Which choice below correctly describes the organization of the nervous system
CNS = Brain and spinal cord. Organize and analyze information.
PNS = All the nerves outside of the CNS and sensory organs. Connect rest of body to CNS
CNS = All the nerves in the body. PNS = Only the brain and spinal cord. Both function to control only voluntary actions.
CNS = Sensory organs and spinal cord. PNS = Only the brain. Both function to transmit signals to muscles only.
CNS = Brain, spinal cord, and all peripheral nerves. PNS = Only sensory organs. Both function to regulate blood pressure only.
What are the parts of the integumentary system?
Skin, Hair and Nails
Bones, Muscles and Tendons
Heart, Lungs and Brain

The nervous system controls only the digestive system, not the cardiovascular system.
