Organ Systems Vocabulary

Skeletal System

support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive

Hormonal Modification

Alterations in hormonal levels yield predictable modifications in the behavior patterns of an animal in a wide variety of situations

Lymphatic System

It is responsible for the removal of interstitial fluid from tissues. It absorbs and transports fatty acids and fats as chyle from the digestive system. It transports white blood cells to and from the lymph nodes into the bones.

Reproductive System

The purpose of the organs of the male reproductive system is to perform the following functions: To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen) To discharge sperm within the female reproductive tract during sex.

Organ Systems

an organ system is a group of organs that work together to perform one or more functions. Organs make up an organism. In the human body, major systems are the circulatory system, the respiratory system, the nervous system, the endocrine system and the digestive system.

Respiratory System

are lungs, to take in oxygen and expel carbon dioxide as we breathe; is a series of organs responsible for taking in oxygen and expelling carbon dioxide.

Stomata

are minute aperture structures on plants found typically on the outer leaf skin layer, also known as the epidermis. They consist of two specialized cells, called guard cells that surround a tiny pore called a stoma.

Nervous System

consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

Integumentary System

consists of the skin, hair, nails, glands, and nerves. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.

Circulatory System

in the delivery of oxygen, nutrient molecules, and hormones and the removal of carbon dioxide, ammonia and other metabolic wastes. Capillaries are the points of exchange between the blood and surrounding tissues.

Tissue

is a cellular organizational level intermediate between cells and a complete organ. A tissue is an ensemble of similar cells from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

Organism

is a creature such as a plant, animal or a single-celled life form, or something that has interdependent parts and that is being compared to a living creature. An example of an organism is a dog, person or bacteria.

Muscular System

is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.

Homeostasis

is the ability or tendency to maintain internal stability in an organism to compensate for environmental changes. An example of homeostasis is the human body keeping an average temperature of 98.6 degrees.

Function

is the reason some object or process occurred in a system that evolved through a process of selection or natural selection. Thus, function refers forward from the object or process, along some chain of causation, to the goal or success.

Organ

liver Organ, a group of tissues in a living organism that have been adapted to perform a specific function. In higher animals, organs are grouped into organ systems

Digestive System

mouth, even the smell of food can generate saliva, which is secreted by the salivary glands in the mouth, contains an enzyme, salivary amylase, which breaks down starch. Teeth, which are part of the skeletal system, play a key role in digestion

Excretory System

of an organism's body that performs the function of excretion, the bodily process of discharging wastes. The Excretory system is responsible for the elimination of wastes produced by homeostasis.

Structure

the arrangement of and relations between the parts or elements of something complex.
