Pancreas
Pancreas act as both the Exocrine and Endocrine glands. The Exocrine part consists of Islets of Langerhans which contain two types of cells, alpha cells, and beta cells. Alpha Cells secrets Glucagon and beta cells secrets Insulin.
- Glucagon( Hyperglycemia hormone) is a peptide hormone, that plays an important role in maintaining normal blood glucose levels. It stimulates gluconeogenesis and glycogenolysis, by acting on liver cells, thereby increasing blood glucose levels. It reduces cellular glucose uptake and its utilization. Hyperglycemia leads to Diabetes mellitus characterized by loss of glucose in urine and the formation of ketone bodies.
- Insulin(Hypoglycemic hormone) is a peptide hormone. It stimulates glycogenesis by acting on liver and adipose cells. It enhances cellular glucose uptake and its utilization.
NCERT Notes for Class 11 Biology Chapter 19: Chemical Coordination and Integration
NCERT Notes Biology Class 11 Chapter 19 Chemical Coordination and Integration: The study of chemical coordination and Integration forms an important part of human physiology. Chemical coordination, integration, and regulations in the human body are carried out by special chemicals called hormones. Regulation, growth, and development of our organs, the endocrine glands, and cells are carried out by hormones.
Here, in Chapter 19 of Biology Class 11 NCERT Chemical Coordination and Integration, we will study the Human endocrine system, Hormones, and their mechanism of action.
