From the anatomy of prokaryotes & eukaryotic cells to plant anatomy, we are finally
getting a closer look at the anatomy of vertebrates. Some vertebrates can be either
ectothermic or endothermic. Homeostasis is what vertebrates use to maintain a balance, a constant internal environment under threats.

What is Anatomy?
The word Anatomy comes from the Greek ana- meaning "up", and tome- meaning "a cutting" (Nordqvist). Anatomy is the "focus on the structure of living organisms by looking at the components of an organism's biological systems as well as the structure of the organs and tissues that make up their biological systems" ("What is Biology and Physiology?"). To begin to study the structures in anatomy, one must know the Hierarchical Organization of Body Plans. "Cells are organized into tissues, a group of cells with similar appearance and a common function. Different types of tissues are organized into functional units called organs" (Campbell 936). These organs then come together to form organ systems which is an organization of structures that perform a specific function or task. There are 12 organ systems in a human body:
tHE 12 oRGAN SYSTEMS
Digestive System
Main components: Mouth, pharynx, esophagus,
stomach, intestines, liver, pancreas, anus
Main function: takes in and absorbs nutrients and eliminates wastes

Circulatory System
Main Components: The heart, Blood, and Blood vessels (Arteries and Veins)
Main Functions: carries food, oxygen,and water to the body. cells and waste are removed.

What is Physiology?
Physiology unlike anatomy "is the science of life. It is a broad science which aims to understand the mechanisms of living, from the molecular basis of cell function to the integrated behaviour of the whole body. Physiology is an experimental science that underpins the biological and clinical sciences; it is key to the detection, prevention and treatment of disease. Without an understanding of basic physiology, progress made in other areas – such as the sequencing of the human genome – is limited because every biological advance must ultimately be related to the behaviour of the whole organism."
