Parathyroid Gland
The parathyroid gland which is situated at the back side of the thyroid gland, secrets peptide hormone known as parathyroid hormone. Its level in the body is regulated by the circulating level of calcium ions. PTH is a hypercalcemic hormone, that is, it increases the blood Ca2+ levels, by following processes: stimulating the process of bone resorption, stimulating reabsorption of Ca2+ by the renal tubules, and increasing Ca2+ absorption from the digested food. It plays an important role in maintaining calcium balance in the body.
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.
