Changes in the environment that can provoke a response from organisms.

The ability of an organism to maintain a stable internal environment despite changes outside.

Animals react to harmful stimuli to protect themselves from threats.

Responses to stimuli lead animals to resources essential for survival.

Responding to mating-related stimuli ensures species survival.

Animals communicate and respond to signals to maintain group dynamics.

Complex network that processes stimuli and triggers responses in organisms.

Animals must adjust behaviors to respond to changing environmental conditions.

Organisms that hunt for food and those that are hunted.

A system that regulates homeostasis through hormones in response to changes.

A system that defends against infections and diseases.

Part of the nervous system comprising the brain and spinal cord.

Nerves that connect the CNS to limbs and organs.

Specialized cells that transmit nerve impulses.

The ability to gather, interpret, and react to external and internal changes.

Early humans survived by developing better tools and weapons, and by interpreting their surroundings.

Early humans relied on sight and sound to detect predators and understand animal movements.

Early humans learned to track animals by observing footprints and behaviors to predict locations.

The development of our brains enabled interpretation of stimuli, aiding in survival and hunting success.

Humans must maintain an internal body temperature of 37°C for optimal chemical reactions.

The nervous system helps humans respond to changes in temperature, maintaining homeostasis.

Despite less acute senses, human intelligence and social cooperation led to dominance over other species.

Early human intelligence allowed for the creation of complex language, enhancing communication and strategy.

Nerve cells that transmit sensory information to the brain.

Nerve cells that convey signals from the brain to muscles and glands.

Body reacts to temperature below 37°C by reducing blood flow to the skin and causing shivering.

Narrowing of blood vessels in the skin to reduce heat loss when cold.

Ceasing sweat production when body temperature drops to conserve heat.

Muscle contractions that generate heat when the body is cold.

Maintaining blood sugar levels around 100 mg/dL to provide energy without harm.

Extreme levels of blood sugar can be harmful to health and need regulation.

The amount of glucose present in the blood.

A simple sugar that is a primary energy source for cells.

The build-up of plaque in arteries due to high blood sugar.

A hormone secreted by the pancreas that lowers blood sugar levels.

When blood sugar rises, the pancreas secretes insulin.

A state where the brain shuts down due to insufficient glucose levels.

A test where no food is eaten for 10-16 hours before measuring glucose levels.

Can lead to kidney disease, vision loss, and poor wound healing.

A hormone secreted by the pancreas that raises blood glucose levels.

A condition characterized by high blood sugar due to insulin issues.

A form of diabetes usually occurring in adolescence, due to lack of insulin production.

A form of diabetes where insulin is produced but cells are resistant to it, often due to poor lifestyle.
