Homeostasis is one of the topics one should be expecting in examinations like IGCSE, GCSE, WASSCE, GCE, NECO, SAT.

Osmoregulation (homeostasis)-in unicellular organism is ensured by the use of contractile vacuole. The main organs involved in homeostasis in multicellular organisms include kidney, liver, skin, ductless glands (hormones) and the brain which has the overall control of the homeostatic process in the body.
The regulation of homeostasis depends on three mechanisms:
1. Receptor 2. Control Centre 3. Effector.
The entire process continuously works to maintain homeostasis regulation.
1. Receptor: the receptor is the sensing component responsible for monitoring and responding to changes in the external or internal environment.
2. Control Centre: The control centre is also known as the integration centre. It receives and processes information from the receptor.
3. Effector: The effector responds to the commands of the control centre. It could either oppose or enhance the stimulus.

Biological systems like those of your body are constantly being pushed away from their balance points. For instance, when you exercise, your muscles increase heat production, nudging your body temperature upward. Similarly, when you drink a glass of fruit juice, your blood glucose goes up. Homeostasis depends on the ability of your body to detect and oppose these changes.
Roles of Pancreas and Liver in Homeostasis.
During a meal, the pancreas will secrete insulin and suppress glucagon, causing the liver to store glucose as glycogen.
Alternatively, when blood sugars are low, the liver can convert glycogen into glucose through a process known as glycogenolysis.
The pancreas controls the concentration of glucose in the body by producing the hormones insulin and glucagon which stimulate the liver. Insulin and glucagon are chemical hormones messengers.

Physics and chemistry are not difficult. It's a reasoning and logic to acquire. In case of difficulties React quickly so as not to allow the gaps to accumulate: with a little will remediation is always possible.

I am a principal teacher of physics chemistry with a long experience in teaching the French system and the Tunisian system which allowed me to devote myself to the regular follow-up of students in difficulty or wanting to excel.
I offer personalized tutoring according to the needs of the student to allow the student to remedy his shortcomings and acquire the right methodology + enrich his knowledge.
courses for all levels from high school to high school (different sections)
for each session I make sure that the student has assimilated the previous knowledge and revised his homework and then begins a new part of the course: explanation, summaries and exercises of applications. Before each test, we prepare different exams and I make sure that the student has assimilated all the knowledge.
In case of previous difficulties I make sure to remedy these shortcomings and catch up.
the schedules are flexible and the courses are personalized.
Thanks to the courses I teach, you will quickly see that physics and chemistry are not difficult. It is intellectual gymnastics, reasoning and logic to be acquired. React quickly in the event of difficulties so as not to allow the gaps to be added: remediation will be all the easier.
My mission is to help the learner j to take off his notes by overcoming his difficulties and in particular by gaining self-confidence.

Currently, I am a student at the University of Liège in the faculty of medicine, I am 19 years old and I am very motivated and passionate about showing my students that science is not that annoying, and even.. c 'is amusing !
I also offer classes during the school year where you can focus on upcoming tests, homework to complete and understand, etc.
But here, I offer you a preparation for the coming year as well as a refresher course if necessary (since if you don't understand the basics, the rest will be even less easy).
