Biology Systems Part 2 Quizs

Spleen

• An organ involved in the production and removal of blood cells and forming part of the immune system.

• A gland that produces hormones regulating metabolism.

• A muscle responsible for the movement of the body.

• An organ that filters toxins from the blood.

Nervous System

• A complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.

• A system responsible for the production of hormones in the body.

• A network of blood vessels that supply oxygen to the brain.

• A collection of muscles that control voluntary movements.

Stimulus

• A detectable change in the internal or external environment that influences or causes a temporary increase of physiological activity or response in the whole organism or in any of its parts.

• A permanent alteration in the genetic structure of an organism.

• A response to a specific environmental condition that does not affect physiological activity.

• A random event that has no impact on an organism's behavior or physiology.

Tonsils

• Two small masses of lymphoid tissue in the throat, one on each side of the root of the tongue.

• Large glands located in the neck that produce hormones.

• Small organs that filter blood and produce red blood cells.

• Muscles in the throat that aid in swallowing.

Central Nervous System (CNS)

• Consists of the brain and spinal cord.

• Consists of the heart and lungs.

• Consists of the stomach and intestines.

• Consists of the kidneys and bladder.

B Cell

• A type of lymphocyte that produces antibodies.

• A type of red blood cell that carries oxygen.

• A type of white blood cell that fights infections.

• A type of platelet involved in blood clotting.

Memory Cell

• A type of cell that stores information permanently.

• A long-lived lymphocyte capable of responding to a particular antigen on its reintroduction, long after the exposure that prompted its production.

• A short-lived cell that responds immediately to any antigen.

• A cell that only functions during the initial exposure to an antigen.

Receptor

• A type of neurotransmitter that transmits signals between neurons.

• A protein molecule that receives and responds to a neurotransmitter, hormone, or other substance.

• A hormone that regulates metabolic processes in the body.

• A type of cell that produces neurotransmitters.

Immunity

• The ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.

• The process by which organisms obtain energy from food.

• The mechanism by which organisms reproduce and pass on their genetic material.

• The ability of an organism to adapt to its environment over time.

Peripheral Nervous System (PNS)

• Consists of the nerves and ganglia outside of the brain and spinal cord.

• Is responsible for processing sensory information within the brain.

• Controls involuntary functions such as heart rate and digestion.

• Is primarily composed of the brain and spinal cord.
