The Human Body in Health & Disease Flashcards
Chapter 2
Anatomical Reference Systems
Terms used to describe the location of body planes, directions, and cavities
Structures of the Body
The cells, tissues, and glands that form the body systems that work together to enable the body to function properly
Genetics
The genetic components that snsfer characteristics from parents to their child
Tissues
A group of similarly specialized cells that work together to perform specific functions
Glands
A group of specialized cells that is capable of producing secretions
Body Systems and Related Organs
Organs are somewhat independent parts of the body that perform specific functions. Organs with related functions are organized into body systems
Pathology
The study of the nature and cause of disease that involve changes in structure and function

plas/o
plas/i
formation
abdominal cavity
contains the major organs of digestion
adenocarcinoma
a malignant tumor that originates in the glands and may spread to other parts of the body
adenoma
benign tumor that starts in the epithelial tissue of a gland or gland-like stucture
anaplasia
a change in the structure of cells and in their orientation to each other
anatomy
the study of the structures of the body
anomaly
a deviation from what is regarded as normal
anterior
situated in the front
aplasia
the defective development, or the congenital absence, of an organ or tissue
atresia
congenital absence or narrowing of a normal body opening or passage
autopsy
a postmortem examination

the spread of pathogens through infected blood or other body fluids
caudal

cephalic
toward the head
chromosome
a genetic structure located within the nucleus of each cell
communicable disease
any condition that is transmitted from one person to another either directly or by indirect contact with contaminated objects
congenital disorder
an abnormal condition that exists at the time of birth
cytoplasm
the material within the cell membrane that is not part of the nucleus
distal
situated farthest from the midline or beginning of a body structure
dorsal
the back of the organ or body
dysplasia
the abnormal development or growth of cells, or the presence of abnormal cells within a type of tissue
endemic
the ongoing presence of a disease within a population, group, or area
endocrine glands
produce hormones, do not have ducts
epidemic
