One of the many types of balanced homeostasis are the levels of pH.

negative feedback loop

A primary mechanism of homeostasis, whereby a change in a physiological variable that is being monitored triggers a response that counteracts the initial fluctuation.

It is a brain based mechanism that gives the brain messages for it to respond to a negative situation, physically.

positive feedback loop

A physiological control mechanism in which a change in some variable triggers mechanisms that amplify the change.

It is a crucial brain cell that transports thoughts and the primary of the nervous system.

sensory neuron

A nerve cell that receives information from the internal and external environments and transmits the signals to the central nervous system.

It is the brains messenger as it sends signals from neurons.


An association neuron; a nerve cell within the central nervous system that forms synapses with sensory and motor neurons and integrates sensory input and motor output.

A highway through the brains neuron system, and it transports through major cells.

Adrian Gonzalez Period 1 Vocabulary




motor neuron

A nerve cell that transmits signals from the brain or spinal cord to muscles or glands.

Even though signal travel through so many parts of the brain the motor neuron is the one responsible for talking to the body.

action potential

A rapid change in the membrane potential of an excitable cell, caused by stimulus-triggered, selective opening and closing of voltagesensitive gates in sodium and potassium ion channels.

I sudden change in the brains membrane of potential that opens the brains voltage areas.


A typically long extension, or process, from a neuron that carries nerve impulses away from the cell body toward target cells.

It is the transmission and changes carrier for the neurons.


One of usually numerous, short, highly branched processes of a neuron that conveys nerve impulses toward the cell body.

A branch that breaks into the body to transport charges or commands to the body from the neurons.


A chemical messenger released from the synaptic terminal of a neuron at a chemical synapse that diffuses across the synaptic cleft and binds to and stimulates the postsynaptic cell.

A tiny chemical that travels through certain part of the brain and works a key to open gates and it is involved in creating pleasure.

Adrian Gonzalez Period 1 Vocabulary





The locus where one neuron communicates with another neuron in a neural pathway; a narrow gap between a synaptic terminal of an axon and a signal-receiving portion (dendrite or cell body) of another neuron or effector cell. Neurotransmitter molecules released by synaptic terminals diffuse across the synapse, relaying messages to the dendrite or effector.

When it is time for a two neurons to communicate through the synapse to send messages or transmitters.


On or in a cell, a specific protein molecule whose shape fits that of a specific molecular messenger, such as a hormone.

As lock and key the receptor waits for that molecule that fits it to take action.


A small, intracellular membranebound sac.

It is a small organ that is found in all cells.


A line of defense triggered by penetration of the skin or mucous membranes, in which small blood vessels in the vicinity of an injury dilate and become leakier, enhancing the infiltration of leukocytes; may also be widespread in the body.

When a foreign item breaks in through the first layer of skin bacteria gets in, in order to protect its system from invasion cells attack in result of inflammation.


is a common medical sign characterized by an elevation of temperature above the normal range of 36.5–37.5 °C (98–100!°F) due to an increase in the body temperature regulatory set-point.[2] This increase in set-point triggers increased muscle tone and shivering.

A fever is the attack of a virus that is foreign to the body, and it is in a process of heat to kill that virus.

Adrian Gonzalez Period 1 Vocabulary





Skin is the soft outer covering of vertebrates.

The first layer of defense of the human body.

passive immunity

Passive immunity is the transfer of active humoral immunity in the form of readymade antibodies, from one individual to another.

It is using previous or familiar material from another individual to destroy a foreign bacteria or virus.

active immunity

Immunity is a biological term that describes a state of having sufficient biological defenses to avoid infection, disease, or other unwanted biological invasion. In other words, it is nothing but the capability of the body to resist harmful microbes from entering the body. Immunity involves both specific and non-specific components.

It is the bodies natural and powerful ability to take care of foreign individuals without the need of medicine or other type of vaccine.


One of two prokaryotic domains, the other being the Archaea.

A prokaryotic cell that infiltrates in the body to reproduce in an malignant or positive way.


A submicroscopic, noncellular particle composed of a nucleic acid core and a protein coat (capsid); parasitic; reproduces only within a host cell.

A small non-living thing that requires another to reproduce, for example

Adrian Gonzalez Period 1 Vocabulary





An organism that absorbs nutrients from the body fluids of living hosts.

A dominant specie or virus that takes over another to reproduce itself or survive.

memory T cell

A clone of long-lived lymphocytes, formed during the primary immune response, that remains in a lymph node until activated by exposure to the same antigen that triggered its formation. Activated memory cells mount the secondary immune response.

It recollects the foreigns material data to understand it and remembers them forever so you can never get the same disease ever again.

killer T cell

Natural killer T (NKT) cells are a heterogeneous group of T cells that share properties of both T cells and natural killer (NK) cells.

The cell that destroys foreign substances or organisms.

helper T cell

A type of T cell that is required by some B cells to help them make antibodies or that helps other T cells respond to antigens or secrete lymphokines or interleukins.

A t cell that helps make antibodies as a response.

B cell

A type of lymphocyte that develops in the bone marrow and later produces antibodies, which mediate humoral immunity.

A cell that provides aid through reproduction of antibodies to fight any of the substances or chemicals that the body is not familiar with.

memory B cell

A clone of long-lived lymphocytes, formed during the primary immune response, that remains in a lymph node until activated by exposure to the same antigen that triggered its formation. Activated memory cells mount the secondary immune response.

This secures no second respond to the same immunities.

Adrian Gonzalez Period 1 Vocabulary





A foreign macromolecule that does not belong to the host organism and that elicits an immune response.

It is a chemical that body is completely unfamiliar with but aids it in case that that a similar particle of the same can become harmful to the body.


An antigen-binding immunoglobulin, produced by B cells, that functions as the effector in an immune response.

it is a perfectly fitted molecule that is a produce of the b cell for future immune response.


An organism or a virus that causes disease.

Foreign organism that infiltrates its way into the body to cause harm.


A type of endocytosis involving large, particulate substances.

I do not really know I am completely tired of this, can I just stop? I would but this is really due in two days.

white blood cell

White blood cells, or leukocytes (also spelled "leucocytes"; from the Greek word leuko- meaning "white"), are cells of the immune system involved in defending.

These are crucial to defend the body and have their name white for the color of them compared to other blood cells.

Adrian Gonzalez Period 1 Vocabulary





cellular immunity

The type of immunity that functions in defense against fungi, protists, bacteria, and viruses inside host cells and against tissue transplants, with highly specialized cells that circulate in the blood and lymphoid tissue.

A almost universal body immunity to all microorganism or just overall self defense to a list of these. Basically natural.

humoral immunity

The type of immunity that fights bacteria and viruses in body fluids with antibodies that circulate in blood plasma and lymph, fluids formerly called humors.

Body immunity through battle and experience.


A chemical that kills bacteria or inhibits their growth.

Synthetic bacteria and virus resistant towards body aid.


A harmless variant or derivative of a pathogen that stimulates a host's immune system to mount defenses against the pathogen.
