Digestive System I Respiratory System Cardiovascular System Components & Processes of Blood Digestive System II
100
What is the pancreas?
This organ lies behind the stomach. It produces most of the digestive enzymes, and is important for regulating blood glucose levels.
100
What is the epiglottis?
This flap of cartilage prevents food from entering the trachea.
100
What are veins?
The largest reservoir of blood is found in these vessels.
100
What is hemoglobin?
RBCs carry loads of this protein. In fact, they most likely lost their nuclei to carry more of it. It serves to carry oxygen, and even a little CO2.
100
What is amylase?
This enzyme aids in digesting carbohydrates.
200
What is the fundus?
The upper hump-shaped area of the stomach nearest the esophagus is called this.
200
What is the Left & Right bronchus?

[bronchi]
These two passageways carry air between the trachea and bronchioles.
200
What is smooth muscle?
This muscle tissue allows arteries to constrict and dilate? Processes known as vasoconstriction and vasodilation.
200
What is a thrombus?
An immobile clot. Opposite an embolus.
200
What are villi and microvilli?
These work to increase the surface area of the small intestine, thereby increasing absorption.
300
What is the ileocecal valve?
This valve is where undigested remains from the small intestine enter the large intestine.
300
What is inspiration?

[take in air, increase in chest/lung volume]
This occurs when the diaphragm and the intercostal muscles contract.
300
What is the systemic circuit?
This circulatory circuit is between the heart and the tissues of the body.
300
What is water?
Approximately 90% of plasma is this substance.
300
What is the Lock and Key Model?
Enzymes do not undergo a conformational change in this model of how enzymes interact with substrates.
400
What is pH?
HCl and NaHCO3 are important for regulating this, making sure it is just right for certain enzymes.
400
What is a concentration gradient?
Proper ventilation of the lungs is required to maintain this. Thus preventing equilibrium between the alveoli and the blood.
400
What is 100?
If someone is said to be experiencing tachycardia, their heart rate must be above this number.
400
What are the A and Rh/D antigens?
People who are B- would develop these two types of antibodies if exposed to the corresponding antigens.
400
What is 2?
This is the number of sphincters present in the anus.
500
What are co-factors?
These inorganic molecules help enzymes function
500
What is external respiration?
This type of circulation occurs between alveoli and the blood.
500
What are elastic arteries?
These vessels experience the highest pressures. That is, the occur closest to the heart.
500
What is agglutination?
The process where erythrocytes stick together without the protein fibrin is called this.
500
What is the cardiac sphincter?
This sphincter regulates the entry of food into the stomach.
