Exam: Anatomy Flashcards
What are the four stages of digestion
Injestion, digestion, absorbtion, elimination
Salivary amaylase: production location
Saliva
Salivary amaylase: site of reaction
Mouth
Salivary amaylase: reaction
Starts the breakdown of starch
Pepsin: produced where
Gastric fluids
Pepsin: site of reaction
Stomach
Pepsin: reaction
Protiens into smaller polypeptide chains
Tryspin: reaction
Smaller polypeptide chains into even smaller polypeptide chains
All enzymes are produced in the pancreas and reacts in the small intestine, which two don’t follow this rule.
Salivary amylase and pepsin.
Lipase reaction
Lipids into fatty acids + glycerol
Pancreatic amylase reaction
Polysaccride (carbs) into monosaccrides
Enterokinase reaction
Activates trypsinogen into tryspin
Erespins reaction
Complete protein digestion (polypeptide chains into amino acids)
Peptidases reaction
Protein digesting enzymes (protiens into amino acids)
Maltase
Maltose into simple sugars (monosaccrides)
Gastrin: production
Stomach
Gastrin: Action
Signals stomach to secrete gastric juices
Secretin: location
Small intestine
Secretin: action
Signals pancreas to secrete pancreatic fluids into small intestine
Insulin: location
Pancreas
Insulin: action
lowers blood glucose levels
Glucagon: location
Pancreas
Glucagon : action
Raises blood glucose levels
Cholecystokinin (CCK): production
Small intestine
Cholecystokinin (CCK): action
Stimulates gallbladder to secrete bile into small intestine
How can you separate hormones and enzymes
Hormones end with n with the exception of pepsin and tryspin
How does the brain control the respiratory system
An increase of CO2 results in faster breathing. The medulla oblongata controls this.
What are chemoreceptors
Detects CO2 and O2 levels. The carotid and Aorta
The three blood vessels in the body
Veins= brings deoxygenated blood to heart
Arteries= brings oxygen to body
Capillaries= gas exchange
