How does exercise affect the cardiovascular system?
What is it strengthens the heart and improves circulation?
How does the nervous system help regulate heart rate?
What is it sends signals to speed up or slow down the heart?
What is the main function of the nervous system?
What is it controls and coordinates body activities?
What is the main function of the cardiovascular system?
What is it transports nutrients and oxygen to cells?
Damage to the nervous system can stop the brain from sending signals to this respiratory muscle.
What is the diaphragm?
Lack of this essential activity affects memory, focus, and emotional control.
What is sleep?
How do the respiratory and cardiovascular systems work together?
What is the respiratory system brings in oxygen for the cardiovascular system to transport?
What type of cells carry signals in the nervous system?
What are neurons?
What are the components of blood?
What are red blood cells, white blood cells, platelets, and plasma?
What is the main organ of the respiratory system that uses osmosis to exchange oxygen with carbon dioxide?
Alvioli
Eating too much salt can raise this, putting stress on arteries and the heart.
What is blood pressure?
How does exercise affect both the respiratory and cardiovascular systems?
What is it increases oxygen demand and improves efficiency?
What is the role of the spinal cord?
What is it transmits signals between the brain and the body?
What is the primary function of the respiratory system?
What is it to exchange oxygen and carbon dioxide?
The respiratory system provides oxygen, and the cardiovascular system delivers it to this system to control body functions.
What is the nervous system?
Regular aerobic exercise helps your lungs take in more of this gas.
What is oxygen?
What happens to the respiratory system during heavy exercise?
What is it increases breathing rate to supply more oxygen?
How does the nervous system respond to danger?
What is it triggers the fight-or-flight response?
What structure prevents food from entering the trachea?
What is the epiglottis?
When one of these systems fails, the others are affected because they depend on oxygen and blood circulation to work properly.
