What is Histology?
The study of tissues. Analysis of the structure and function of the cells in tissues.
Are acini exocrine or endocrine cells?
Exocrine
What are B cells?
Detect rise in blood glucose concentration.
Release Insulin
What are Alpha cells?
Detect fall in blood glucose concentration.
Release glucagon.
What responses make blood glucose concentration fall back to normal?
Glycogenesis
What responses cause blood glucose concentration to rise back to normal?
Glycogenolysis
Gluconeogenesis
What causes blood glucose to rise?
Eating
What causes like glucose levels to fall?
Exercise
What is Glycogenolysis?
The conversion of glycogen to glucose.
What is Glycogenesis?
The conversion of glucose to glycogen
What is Gluconeogenesis?
Conversion of amino acids and data into glucose.
What is glucogon?

What is a hepatocyte?
A liver cell.
What is the pancreatic duct?
The structure that carries the digestive enzymes from the pancreas to the small intestine.
What are Alpha Cells?
Cells in the Islet of Lagerhans that secrete glucagon.
What are B cells?
Cells in the Islet of Langerhans that secrete insulin.
What is a acinus?
Collection of cells in the pancreas surrounding a tubule with an exocrine function.
What is a tubule?
A tiny duct that collects digestive enzymes seceded from cells. The ducts join together to form the larger pancreatic duct.
What are the two ways of insulin excretion?
Resting State and Gkucose-Stimulated State
