Lab 1: Physiological Measurements

Which two hormones does the pancreas produce

Glucagon and Insulin

Which feedback mechanisms regulate blood glucose

Negative feedback

Increased blood sugar levels signal the pancreas to release which hormone

Insulin

What is the role of insulin

to help glucose across the cell membrane

High blood glucose

Hyperglycemia

Low blood glucose

hypoglycemia

Blood glucose levels drop what does the pancreas do?

stop producing insulin and release glucagon

Glucagons role

Causes the excess glucose stored in the liver and muscle cells to be released

Glucagon and insulin are what to eachother

Antagonistic

After a meal blood glucose is typically

high

How does insulin help glucose into the cell

through activating glut4 channels to fuse with plasma membrane

Type 1 diabetes

Insulin not produced or reduced in production

Type 2 diabetes

Cells become resistant to insulin

Increase in blood pressure is an example of which feedback loop

Positive feedback loop

How does high blood sugar affect blood pressure

Raises blood pressure
