blood glucose: Biology

How does the pancreas e stop blood glucose levels from becoming too high ?

The pancrease detects when the blood sugar is increasing. The pancrease releases insulin into the bloodstream this hormone releases causes glucose to move into cell and get converted into glycogen

What is the Islet of Langerhans ?

Patches of receptors

What is Hypoglycaemia?

When blood glucose is too low

What is Hyperglycaemia?

When blood glucose is too high

When the blood glucose concentration is too low, Glucagon arrives at the liver cell and stimulates the too what ?

Convert glycogen ( more complex carbohydrate) back into glucose

Glucose will then diffuse out of the liver cell and back into the bloodstream

Glycogen ?

Complex carbohydrate found in the liver and muscle

Regulation of blood glucose is an example of what?

A negative feedback loop

Glucose ?

The sugar used in respiration

Glucagon ?

A hormone that stimulate the liver to breakdown glycogen to glucose

Hat happens during type 1 diabities ?

The blood glucose may raise fatally high levels bc the pancrease does not secrete enough insulin

What happens during type 2 diabetes?

The blood stops responding to its own insulin

What does the pancrease produce ?

Glucagon which allows glycogen to convert back into glucos released into the blood

When does Glucagon interact with insulin ?

In a negative feedback cycle to control glucose levels

What is our blood glucose concentration monitored by ?

The pancrease

What does the pancrease produce ?

Hormone insulin high allows glucose to move from the blood into the cells and to be stored as glycogen into the liver and muscle

Which gland produces hormones that stimulates the other glands to produce hormones ?

Pitituary

How do hormones travel from one gland to anouther ?

Blood stream

What are the 2 glands involved in human reproduction?

Testies

Ovaries

Explain how the body responds to an increase in blood glucose concentration?

The pancrease releases insulin which allows glucose to move from blood into the cell to be stored as glycogen in the liver + muscle

What is the difference between type 1 and type 2 diabetes ?

1 = treated by insulin by replacing by replacing what they don’t have

2 = still make insulin but can not respond to it

Which type of diabetes is more prevented ?

Type 2

What happens during Type 1 diabetes ?

The pancrease cannot produce insulin so blood cels can’t remove glucose from the blood

Hormones that control blood glucose levels are secreted by the ?

Pancrease

The maintenance of constant internal conditions despite changing internal external environments is called what ?

Homeostasis

A change in the environment detected by receptors is called a ?

Stimulus

A rapid nervous response which do not pass through the CNS is called a ?

Reflex arc

The 2 types of effectors are ?

Muscles and glands

The gland informally known as the master gland is the ?
