Organization Of The Body Flashcards
Biology
The study of all forms of life and living things
Anatomy
Cutting apart
Embryology
The origin( beginnings) and the development of an organism.
Covers embryonic stage-2nd to 8th week after conception.
After 8 weeks, the developing organism is called fetus
Histology
Studies the body microscopically- the minute structures and their composition, plus the functions of normal cells, tissue, and organs
Pathology
Studies the changes caused by disease to the structures of the body or changes due to disease that alter the functions of the body
Physiology
Studies the normal activity and functions of the body
Epithelial or skin cell
May be square and flat
Fat cell
Contains large vacant spaces for fat storage
Muscle cell
Long and slender
Nerve cell
May be long and have finger like extensions, which carry impulses
Four types of tissue
Connective tissue
Epithelial tissue
Muscle tissue
Nerve tissue
Epithelial tissue
- Found in the skin and in the lining of blood vessels
- Makes up the Luther covering of external and internal body surfaces ( such as skin and mucous membranes )
- Linings of the digestive, respiratory, and urinary tracts
Connective tissue
- Supports and encases body structures
- holds organs in place and connects body parts to each other
- The main types of connective tissue are bone, cartilage, dense fibrous (tendons and ligaments ), loose ( connects adjoining structures and adipose tissue that pads and protects, stores fat, and insulate the body against heat loss
Muscle tissue
Contracts
Provides movement
Nerve tissue
Conducts to and from the brain and is composed of nerve cells called neurons
Nervous tissue needs more oxygen and more nutrients than any other body tissue
