Microscopic Anatomy (Histology)
Also known as histology. Microscopic anatomy is the study of cells and tissues as discerned by a microscope. The individuals who specialize in this study are called histologists. The process involves marking and dividing cells and tissues into sections to be viewed under a microscope. The biological samples are dissected into thin slices so that they…

Types of Anatomy
Anatomy could be classified into: Human Anatomy – Human anatomy involves the study of the physical structure of the human body. It focuses on numerous systems, including circulatory, digestive, endocrine, skeletal, lymphatic, nervous, respiratory, urinary, reproductive and muscular systems. Plant Anatomy – Also called the phytotomy. It is the study of the internal structure of a plant…

What is Anatomy?
Anatomy is a branch of biological science which is concerned with the description of body structures of various living organisms as revealed by dissection. The word anatomy is derived from the Greek word “anatomē”, where “ana” means “up” and “tome” means “cutting.” Originally, anatomy was first learnt by cutting up corpses, hence the name “anatomy.”

The study of structure
Living things are defined in terms of the activities or functions that are missing in nonliving things. The life processes of every organism are carried out by specific materials assembled in definite structures. Thus, a living thing can be defined as a system, or structure, that reproduces, changes with its environment over a period of time, and maintains its…

Biological principles
Homeostasis The concept of homeostasis—that living things maintain a constant internal environment—was first suggested in the 19th century by French physiologist Claude Bernard, who stated that “all the vital mechanisms, varied as they are, have only one object: that of preserving constant the conditions of life.” As originally conceived by Bernard, homeostasis applied to the struggle of a single…

Where do biology graduates work?
Biology graduates can hold a wide range of jobs, some of which may require additional education. A person with a degree in biology could work in agriculture, health care, biotechnology, education, environmental conservation, research, forensic science, policy, science communication, and many other areas.

Why is biology important?
As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life. Fields such as genetics and evolution give insight into the past and can help shape the future, and research in ecology and conservation inform how we can…

What is biology?
Biology is a branch of science that deals with living organisms and their vital processes. Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology.

Energy
In biology, energy is essential to drive various biological processes, especially anabolic reactions. Adenosine triphosphate (ATP) is the main energy carrier of the cell. It is released from carbohydrates through glycolysis, fermentation, and oxidative phosphorylation. Lipids are another group of biomolecules that store energy.

Homeostasis
Homeostasis is the tendency of an organism to maintain optimal internal conditions. It entails a system of feedback controls so as to stabilize and keep up with the normal homeostatic range despite the changing external conditions. For instance, it employs homeostatic mechanisms to regulate temperature, pH, and blood pressure. The homeostatic system is comprised of three…
