-It’s composed of lipid (which provide physical properties) and protein (provide function) molecules as well as carbohydrates
-phospholipid bilayer which includes a hydrophilic heads and hydrophobic tails
Function: There are different proteins in the cell membrane 
-Integral protein: forms pores, channels, and carriers in the cell membrane 
-Peripheral proteins include receptor proteins (which respond to extracellular signals), enzymes (which catalyze chemical reactions), cell surface proteins (establish shape), and cellular adhesion molecules (which enables cells to stick to one another).]]> 2019-09-03 13:58:48 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/379453462 ashley_porter3 https://padlet.com/Micalah/unolyh51c9pr/wish/379454528 2019-09-03 14:00:39 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/379454528 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/379459451 2019-09-03 14:10:03 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/379459451 ashley_porter3 https://padlet.com/Micalah/unolyh51c9pr/wish/379461250 Leukocytes are also known as White Blood Cells.  They are responsible for responding to and fighting infection in the body. 
Special Characteristics:
-White blood cells are larger than red blood cells and are fewer in number 
-These cells are highly mobile and can squeeze through tight spaces to fight diseases.  They normally float along with the red blood cells, but can sprout hundreds of "legs" to propel themseles to the infection site when they are needed.
-White Blood Cells can even change shape and become extremely flexible to get to the infection
- These cells lack hemoglobin, but unlike red blood cells, they do have a nucleus.
-Most White Blood Cells are produced in the bone marrow, while the rest are produced in the spleen, lymph nodes, and thymus gland. Leukocytes can not reproduce and divide on their own, they can not undergo mitosis.  They are only produced.
-They benifit our bodies by protecting us from infection and diseases cells. ]]> 2019-09-03 14:13:29 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/379461250 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/379470324 Structure: They are threadlike structure in the cytoplasm and are classified by protein type, diameter, and lysosomes.

Type 1 Diabetes is an autoimmune disease in which T- cells attack the insulin producing beta cells in the pancreas. Interestingly enough, the alpha cells are not attacked and remain able to produce glucagon. ]]> 2019-09-05 21:41:18 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/380668740 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/380709598 In a non diabetic patient, after they eat, their blood glucose level starts to rise and this produces an afferent response from the blood glucose levels, and is sent to the brain where the brain processes the signal and sends an efferent response back to the pancreas to secrete insulin. Then your beta cells will start producing insulin which will then leave the pancreas and travel to cells and connect to the target cell’s insulin receptors. From there, a signal is sent to the GLUT-4 protein which then travels to the cell  membrane and lets glucose into the cell. The cell then stores that glucose as glycogen. Once enough glucose is out of the blood stream that the overall levels are normal, insulin production is stopped. Glycogen is broken down when a persons blood glucose level is too low and they need more sugar in their blood. When the afferent signal is sent to the brain and the efferent signal sent to the pancreas, the pancreas tells the alpha cells to start producing glucagon which then is related and tells the target cells to breakdown the glycogen they stored earlier, into glucose and release it.
In a diabetic patient, when a meal is eaten, the afferent signal is sent to the brain and then the efferent signal to the pancreas. But since a diabetic’s beta cells are destroyed by T-cells, the efferent signal that is sent, cannot be acted upon because the pancreas cannot produce insulin. Therefore, there will be too much glucose in the blood and then the patient, if not treated, can go into ketoacidosis and die. If a diabetic patient has a low blood glucose, some diabetics body will be able to secrete glucagon but with the loss of beta cells, the alpha cells are impaired and cannot do their job.

-increased thirst
-increases trips to the bathroom to pee
-headaches
-blurred vision
-unsteady hands
-weight decrease
-weight increase
-loss of appetite
-gaining of appetite
Treatment: There is no current cure yet for Type 1 Diabetes. Patients are insulin dependent and have to monitor their blood sugar very closely. If not, comas and death can occur. ]]> 2019-09-06 01:11:10 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/380711261 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/380717958 2019-09-06 01:39:35 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/380717958 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/380719203 2019-09-06 01:45:09 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/380719203 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/380719304 2019-09-06 01:45:45 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/380719304 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/380720935 2019-09-06 01:53:19 UTC https://padlet.com/Micalah/unolyh51c9pr/wish/380720935 Micalah https://padlet.com/Micalah/unolyh51c9pr/wish/380721783 Structure: Jelly like substance
