Homeostasis Concepts

Body systems working together when the brain checks CO2 levels and adjusts breathing

• Nervous and Respiratory

• Digestive and Circulatory

• Endocrine and Muscular

• Skeletal and Immune

The feedback loop involved when glucose levels in the blood rise.

• Positive feedback loop

• Negative feedback loop

• Neutral feedback loop

• Cyclic feedback loop

The feedback loop that is not involved in maintaining body temperature.

• Negative feedback loop

• Homeostatic feedback loop

• Positive feedback loop

• Thermoregulatory feedback loop

The body's internal environment must stay

• Within narrow ranges that support human life.

• Completely stable without any fluctuations.

• As variable as possible to adapt to changes.

• In a state of constant change and chaos.

Liver helps to regulate excessive glucose levels in the blood

• By storing glucose.

• By producing insulin.

• By breaking down fats.

• By increasing blood pressure.

Group of organs that work together

• Organ system

• Tissue

• Cell

• Organism

The feedback loop that helps lower blood sugar levels.

• Positive feedback loop

• Negative feedback loop

• Neutral feedback loop

• Cyclic feedback loop

Nervous System

• Primarily involved in rapid control and communication within the body.

• Responsible for the production of hormones.

• Mainly functions in the digestion of food.

• Regulates the body's immune response.

Role of glucagon.

• Glucagon lowers blood glucose levels when they are too high.

• Glucagon raises blood glucose levels when they are too low.

• Glucagon has no effect on blood glucose levels.

• Glucagon converts glucose into glycogen.

The role of the pancreas when blood glucose levels rise.

• Releases insulin to lower blood sugar levels.

• Increases glucagon production to raise blood sugar levels.

• Stores excess glucose as glycogen in the liver.

• Inhibits the secretion of digestive enzymes.
