studies body structure without microscope.
Gross anatomy
studies functional relationships of organs within a system
Systemic Anatomy
studies body part regionally.
Regional anatomy
Regional Anatomy:
Skull
Thorax
Abdomen
Upper limb (Arm)
Head and Neck
requires the use of microscope to study tissues that form the various organs of the body
Microscopic Anatomy (Histology)
Is the branch of anatomy that covers the structural changes that cells, tissues, organs and the human body undergo from fertilization to adulthood.
Developmental Anatomy

derived from a Greek word for study of nature.
Physiology
It is the study of how the body and its part work or function.

Anatomy and Physiology
When structure and function are coordinated the body achieves a relative stability of its internal environment called _______________staying the same.
Homeostasis
Is maintained by adaptive mechanisms ranging from control centre in the brain to chemical substances called hormones that are secreted by various organs directly into the blood streams.
Homeostasis
At its simplest level, the body is composed of atoms. The most common elements in living organism are carbon, hydrogen, oxygen, nitrogen phosphorus and sulfur.
Atoms, molecules and compounds
The smallest independent units of life. All life depends on the many chemical activities of______
Cell
Its basic functions are growth, metabolism, irritability and reproduction.
Cell
made up of many similar cells that perform a specific function.
Tissue
The various tissues of the body are divided in to four groups. These are:
Epithelial, connective, nervous, and muscle tissue
Found in the outer layer of skin, lining of organs, blood and lymph vessels and body cavities.
Epithelial tissue
Connects and supports most part of the body. They constitute most part of skin, bone and tendons.
Connective tissue
Produces movement through its ability to contract. This constitutes skeletal, smooth and cardiac muscles.
Muscle tissue
