What are the antagonistic hormones, and where do they come from
- Insulin is produced by the beta cell, and glucagon is produced by the alpha cell, both are islets of Langerhans cells of the pancreas.
- The pancreas is an endocrine gland because it releases hormones
What does insulin do?
-Insulin is released when food enters the body, and the insulin allows the glucose to enter the liver to be converted into glycogen. make the cell membrane permeable and are fed
-Insulin lowers blood sugar
What does glucagon do?
- Glucagon is released when the body doesn’t eat, and it takes the stored glycogen in the liver and turns it back into glucose, which is then released into the bloodstream.
- increases the blood sugar
blood sugar regulation
The body secretes two hormones, insulin and glucagon, which are used to maintain homeostasis.
The body must maintain a set sugar level in the blood/
too much sugar in the bloodstream
Hyperglycemia- blood is hypertonic, cells dry out
too little sugar in blood bloodstream
hypoglycemia- blood is hypotonic, cells starve
Diabetes
an inability to maintain or control blood sugar levels because of not enough insulin or an insensitivity to insulin
type 1
-juvenile diabetes
-in childhood, the beta cell die,s and not enough insulin is made
-symtomes-higher blood sugar, frequent urination cuz the water and glucose in the body I secreted and not absorbed, loose weight easily, thirsty, excessive drinking, tired and death
-treatment, none , insulin shots
- cause, we don’t know ,mayben genetics
Type 2
- Bodys cells are becoming ressistent to insulin, this means u need more and moreto get the same effect, which u don’t have so your blood sugar levels increase
- 40+
-Causes; genetics, diets, high in refined sugars,simple carbs, soft drinks and lack of fibre, obesity, lack of exercise
-exersise can decrease blood sugar by absorbing into the muscles
symptoms;none at first, then inflammation, tiredness,thirst, blindness, imputness, circulatory disturbance - treatment change in lifestyle
