Histology
Histology is the microanatomy method and a branch of biology that studies the anatomy of tissues. It includes viewing tissue in a magnified view under the microscope. Microanatomy also includes the process of study of organs called organology and the study of cells called cytology. Histopathology is a branch of biology that includes microscopic identification of diseased tissue. The field of histology comprises the preparation of the tissues and collection of cells as specimens for examination under the microscope. These processes are done by technicians like histologists, histotechnicians, and biomedical scientists. Histopathology is the diagnosis and research of tissue diseases that require the examination of tissues and/or cells under a microscope. Histopathologists are in charge of determining tissue diagnosis and assisting clinicians in managing a patient's care.
Endocrine System
Human body functions due to the collective work of the organ systems. One of them is the endocrine system. It is a chemical messenger system constituting the hormones directly released by the endocrine glands into the circulatory system. The study of this system is known as endocrinology. The word 'endon' means inside, and 'crine' means secrete, making the word "endocrine."
What are organ framework level of organization?
Cell is the basic structural and functional unit of all living organisms. An organism is termed as unicellular and multicellular based on number of cell presents in it. Cells grouped to form tissues and tissues organize to form organs.
Two or more organ systems integrate together to execute a common function is termed as organ framework level of organization. Example: In Excretory system kidney combined with ureter and blood and filters the urea the waste product from the blood which is a tissue metabolic waste. Urea is eliminated in the form of urine by the excretory system. Excretory system is combined organs system of kidney, ureter, and blood.
