The levels of organization from simplest to most complex are:

The study of the body at the cellular level is called

is the structural and functional unit of life.

Cells are composed of:

The study of tissues is called

Groups of cells that perform a specialized activity are called

The highest level of organization is the

is a complete living entity capable of independent existence

All complex organisms, including humans, are composed of several body systems that work together to sustain life.

is a body posture used as a reference when describing anatomical parts in relation to each other.

In this position, the body is erect and the eyes are looking forward.

The upper limbs hang to the sides, with the palms facing forward; the lower limbs are parallel, with the toes pointing straight ahead.

anatomists use an imaginary flat surface called a

Prior to the development of modern imaging techniques, conventional x-ray images were taken only on a

The most commonly used planes are:

Anatomical Division: Right and left halves

Anatomical Division: Anterior (ventral) and posterior (dorsal) aspects

Superior (upper) and inferior (lower) aspects

The hollow place or space within the body that houses internal organs is known as a

The two major body cavities are the

located near the posterior part of the body

located near the anterior part of the body

The dorsal cavity is subdivided into the

The ventral cavity is subdivided into the

Two anatomical methods are used to divide this area of the body for medical purposes:

are four divisions of the lower torso demarcated for the purpose of topographical location

They provide a means of defining specific sites for descriptive and diagnostic purposes.

Right lobe of liver, gallbladder, part of pancreas, part of the small and large intestines

Left lobe of liver, stomach, spleen, part of pancreas, part of small and large intestines

Part of the small and large intestines, appendix, right ovary, right fallopian tube, right ureter

Part of the small and large intestines, left ovary, left fallopian tube, left ureter

Whereas the quadrants of the body are used primarily to identify topographical sites

are used primarily to identify the location of underlying body structures and visceral organs.
