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.

I'd like to start by greeting everyone who is reading this and then briefly discuss the teachings I'm providing. Going to medical school is a major step, and while becoming a doctor may have been a big dream of yours, things unfortunately didn't turn out the way you had hoped. You didn't receive what you eagerly want following your bac. I'm here to tell you that earning your bac is just the first step on a longer journey. You have another opportunity to fulfill your lifelong ambitions. What role do I play in this? as someone who has been in your position and ultimately obtained what I want. We will have a customized plan that fulfills your needs, we will correct any unsuccessful methods and build new ones, and I will lead you through the program at every stage.

Welcome to university students or masters and doctoral students!!! I teach the course of Natural Products Chemistry or Phytochemistry or Pharmacognosy. In this class we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy, spectroscopy, mass spectrometry, magnetic resonance and advanced analysis devices used in this field.

This is in addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical and laboratory methods that are carried out in the laboratory to conduct toxicity, antioxidant, and diabetes analyses, etc.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for science and chemistry curricula.

With my qualifications and experience, I hold a master’s degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other graduate degrees and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mendus Organization of the European Union.
