Respiratory System
The main function of the respiratory system.
What is gas exchange?
The main function of the circulatory system.
What is circulating nutrients and wastes throughout the body?
The main function of the digestive system.
What is to break down and absorb nutrients from food?
Moving molecules from high to low concentrations without ATP.
What is passive transport?
A response to a stimulus to maintain homeostasis.
What is a feedback mechanism?
The site of gas exchange in the lungs.
What is the alveoli?
This organ transports oxygenated blood away from the heart to muscles in the body to make ATP.
What are arteries?
Chewing and peristalsis are examples of this.
What is physical digestion?
Moving molecules AGAINST the concentration gradient with ATP.
What is active transport?
When the body raises its temperature during exercise, then sweats to cool off.
What is thermoregulation?
This muscle helps inhale oxygen and exhale carbon dioxide during breathing. It is found below the lungs and expands during inhalation and contracts during exhalation.
What is the diaphragm?
This organ transports deoxygenated blood back to the heart and lungs so that it can get more oxygen.
What are veins?
Enzymes found in saliva, stomach acid, and bile complete this.
What is chemical digestion?
If a freshwater fish is placed into a salt water tank, it will create an environment that the fish cannot maintain homeostasis in. Why?
Overtime, the fish will lose water from its cells because there is a higher concentration of water in the fish than in its environment causing it to pass away.
Being able to regulate bodily processes and keep a constant internal environment in order to survive.
What is maintain homeostasis?
This is a waste that is produced during respiration that needs to be removed from the body.
What is carbon dioxide?
This measures the amount of times your heart beats per minute and can be used to determine if you are healthy and if your body is able to supply nutrients it needs to the body.
What is pulse rate?
What hormone regulates blood sugar levels after eating so that glucose can enter cells to make ATP?
What is insulin?
This analogy is used to explain how specific molecules cause reactions to occur in the cell, as if a door opens to let things into the cell.
What is the lock and key model?
What is only found in plant cells that helps them maintain homeostasis and survive?
- Cell wall
- Chloroplast
- Large central vacuole
This is the amount of breaths you take per minute that can be used to determine the amount of oxygen and carbon dioxide that enters or exits the body.
What is respiration rate?
These are attached to every organ in the body and allows the exchange of nutrients and wastes between organs and the circulatory system.
What are capillaries?
What are some MACROMOLECULES (large molecules) that the body breaks down to absorb nutrients? need two minimum.
What are;
- carbohydrates (sugars), lipids (fats), proteins, and nucleic acids?
These proteins regulate blood glucose levels and allow sugar to enter the cell so that ATP can be produced. There are two.
What are the insulin receptor and glucose channel protein.
What are characteristics of living things?
What are. . .
- Responding to stimuli, being able to reproduce, composed of cells, metabolism
