cell

basic unit of all living things

cell membrane

forms the boundary of the cell

cytoplasm

gel like fluid inside the cell

nucleus

largest structure within the cell, usually spherical and centrally located.

chromosomes

located in the nucleus of the cell. There are 46 chromosomes in all normal human cells, with the exception of mature sex cells, which have 23.

genes

regions within the chromosome. Each chromosome has several thousand genes that determine hereditary characteristics.

dna

comprises each gene: is a genetic material that regulated the activities of the cell.

tissue

A group of similar cells that perform the same function.

muscle tissue

composed of cells that have a special ability to contract, usually producing movement

nervous tissue

similarly specialized cells united in the performance of a particular function; found in the nerves, spinal cord, and brain. It is responsible for coordinating and controlling body activities.

connective tissue

connects, supports, penetrates, and encases various body structures

epithelial tissue

the major covering of the external surface of the body; forms membranes that line body cavities and organs and is the major tissue in glands

organ

two or more kinds of tissues that together perform special body functions

viscera

large internal organs contained in the body cavities, especially in the abdominal cavity

system

group of organs that work together to perform complex body functions

integumtary system

composed of nails, skin, and glands. Forms a protective covering for the body, regulated body temperature.

respiratory system

Composed of nose, pharynx (throat), larynx (voice box), trachea (windpipe), bronchial tubes, and lungs. Performs respiration which provides for the exchange of oxygen and carbon dioxide within the body.

uinary system

composed of kidneys, ureters, bladder, and urethra. Removes waste material from the body, regulates fluid volume, and maintains electrolyte concentration.

reproductive system

Female reproductive system is composed of ovaries, uterine tubes, uterus, vagina, and mammary glands. Male reproductive system is composed of testes, urethra, penis, prostate gland, and associated tubes. Responsible for heredity and reproduction.

cardiovasular system

Composed of the heart and blood vessels. Pumps and transports blood throughout the body.

Lymphatic/Immune System

Composed of a network of vessels, ducts, nodes, and organs. Provides defense against infection.

digestive system

Composed of the gastrointestinal tract which includes the mouth, esophagus, stomach, large and small intestine plus accessory organs, liver, gallbladder, and pancreas. Prepares food for use by the body cells and eliminates waste.

musculoskeletal system

Composed of muscle, bones, and joints. Provides movement and framework for the body, protects vital organs such as the brain, stores calcium, and produces red blood cells.

nervous system

Composed of the brain, spinal cord, and nerves. Regulates body activities by sending and receiving messages.

endocrine system

Composed of glands that secrete hormones. Hormones regulate many body activities.

cranial cavity

space inside the skull containing the brain

spinal cavity

space inside the spinal column containing the spinal cord

thoracic cavity

space in the chest containing the heart, lungs, bronchial tubes, trachea, esophagus, and other organs

adominal cavity

space containing the stomach, intestines, kidneys, adrenal glands, liver gallbladder, pancreas, spleen, and ureters

pelvic cavity

space containing the urinary bladder, certain reproductive organs, parts of the small and large intestine, and the rectum

abdominopelvic cavity

both the pelvic and abdominal cavities
