tissue
Systemic Circulation ANS: The blood supply to all body organs expect for the pulmonary arteries and
veins
Anti-body ANS: defensive protein, made in response to the presence of antigen
Parasympathetic Nervous Symstem ANS: Division of the autonomic nervous system that prepares the
body for 'rest and repair'.

Diploid ANS: a cell with 46 chromosomes, the whole complement of 23 pairs
Glycogen ANS: Storage, very high molecular weight form of glucose
Fixator ANS: any muscle that fixes or limits the movement of a bone or joint
cell ANS: smallest structure and funtional unit of an organism.
Consists of cytoplasm and nucleus enclosed in the membrane
tissue ANS: any of the distinct types of material of which animal or plants are made
Consisting of specialised cells and their products
, Organ ANS: body part composed of different tissues that carries out specific body function
Organelle ANS: intercellular structure that carries out a specific functions
Protoplasm ANS: Living content of a cell that is surrounded by plasma
Cytoplasm ANS: all contents of cell expect the nucleus

Chromosomes ANS: Sausage- shaped structure consisting of a tightly collided molecule of DNA
Adenosine Triphosphate ANS: molecular store of chemical energy for chemical reactions
Diffusion ANS: movement of substances down a concentration gradient, which, does not require energy
or presence of a membrane
Collagen ANS: protein complex consisting of the three collagen
Central Nervous System ANS: part of nervous system consisting of the brain and spinal cord
Autonomic Nervous System ANS: controls involunatary action of the smooth muscles, heart and gland
Catabolism ANS: Breaking down of larger molecules into smaller ones
Anabolism ANS: synthesis of larger molecules from smaller ones
Gene ANS: a unit of heredity, transferred from parents to offspring, held to determine some
characteristic of offspring
Recessive ANS: characterises controlled by genes which are expressed in offspring only when inherited
from both parents
punnet square ANS: diagram used to predict possible outcomes of breeding and the respective
likelihood
phenotype ANS: the expression of genes in an individual e.g. hair colour, height, eye colour
Denature ANS: take away or alter natural qualities.
Hypothalamus ANS: region of the fore brain which coordinates both the autonomic nervous system,
temperature, thirst, hunger and other homeostatic systems
hyperthermia ANS: the condition of having an abnormally low body temperature
neurotransmitter ANS: chemical that transmits an impulse between one nerve and the next, or between
a nerve and neuromuscular junction
