What effect does exercise have on both your circulatory and respiratory systems? Be specific
Your heart rate will increase and breathing rate will increase
What is an observation?
Information obtained through the senses.
What is the purpose of Guard Cells & Stomata?
allows for gas exchange in the plant and helps maintain homeostasis
What are the 5 organs of the circulatory system?
heart, veins, arteries, capillaries & Blood
What is the function of the nervous system?
respond to stimuli, control movements, sense pain, etc.
What is the function of the respiratory system in terms of gas exchange?
Take in oxygen, exhale carbon dioxide
How is the human body organized from SMALLEST to LARGEST?
Cell --> Tissue --> Organ --> Organ System --> Organism
A person not producing enough insulin in their body can lead to
high blood sugar/diabetes
What is the difference between veins and arteries?
Arteries carry oxygenated blood away from the heart and veins bring deoxygenated blood back to the heart to be pumped to the lungs.
Which two systems work together to remove waste products from blood?
respiratory and excretory systems
What are the grape-like structures in the lungs that are the site of gas exchange?
Alveoli
What is a feedback mechanism?
Helps keep body conditions near a normal, steady state
How do drugs/medication disrupt your nervous system in the synapse?
Neurons will not be able to communicate with each other properly
How does your blood get oxygen?
Blood comes to your heart through veins, then it is pumped to your lungs to pick up oxygen. The blood is pumped back to your heart and then pumped to the rest of your body.
Which structures in a human transmit electrochemical messages?
Neurons
Humans breathe more rapidly during exercise than before it because during exercise the blood contains
An increased level of carbon dioxide
The largest organ IN the body is your
skin
What would happen if the myelin sheath of a neuron was damaged?
Chemical messages would be lost and not be sent properly
Describe the pathway of blood using the model we discussed in class. Use the terms oxygen rich and oxygen poor.
Blood is in the heart (oxygen poor) and goes from right atrium to the right ventricle. It is then pumped to the lungs and becomes oxygen rich. From the lungs, it is pumped back to the heart to be pumped to the rest of the body.
What is an interaction of the nervous system with either the respiratory system, or the circulatory system.
Circulatory and Respiratory--The nervous system interacts with these systems by controlling involuntary actions, such as breathing and heart beat.
What is an interaction of the respiratory system with your circulatory system?
Your circulatory systems sends deoxygenated blood from the heart to the lungs so your lungs can give the blood the oxygen it needs.
How does an athlete get nutrients to their muscles?
Nutrients from the food move from the digestive system to the circulatory system, which then carried them to the muscular system.
