Digestive System
This organ is where most nutrient absorption happens in the digestive system.
What is the small intestine?
This gland is often called the 'master gland', as it regulates many other glands in the endocrine system.
What is the pituitary gland?
These two-bean shaped organs filter blood and produce urine.
What are the kidneys?
This term describes the body's ability to maintain a stable internal environment.
What is homeostasis?
These cells in the Islets of Langerhans produce insulin.
What are beta cells?
This substance, produced by the liver and stored in the gallbladder, helps digest fats.
What is bile?
This hormone, secreted by the pancreas, lowers blood glucose levels by effecting an increased uptake of glucose in skeletal and fat cells, and increasing glycolysis in the liver.
What is insulin?
This nitrogenous waste is removed from the body through urine.
What is urea?
In a feedback system, this component detects changes in the internal environment.
What is a receptor?
When blood glucose is low, this hormone raises it be stimulating glycogen breakdown.
What is glucagon?
This process breaks food down using enzymes and acids rather than chewing.
What is chemical digestion?
This condition is where the thyroid gland is overactive, secreting higher levels of thyroid hormones.
What is hyperthyroidism?
This hormone reduces water loss by increasing water absorption in the distal convoluted tube and the collecting duct.
What is ADH (antidiuretic hormone)
This type of feedback loop intensifies the stimulus, such as during childbirth.
What is a positive feedback system?
This term refers to the widening of blood vessels near the skin to lose heat.
What is vasodilation?
Villi and microvilli increase this, helping the small intestine absorb nutrients efficiently.
What is surface area?
Unlike the nervous system, the endocrine system uses these chemicals to send messages.
What are hormones?
This network of capillaries deliver blood to the Bowman's capsule, the first section of the nephron.
What is the glomerulus?
This molecule, cell or organ responds to a signal and produces a response.
What is an effector?
This brain structure acts as the modulator for regulation of water and temperature.
What is the hypothalamus?
This muscular movement pushes food through the digestive tract.
What is peristalsis?
These endocrine glands are responsible for secreting cortisol, adosterone and adrenaline.
What is the adrenal glands?
This section of a nephron is where reabsorption of glucose, amino acids and ions occur.
What is the proximal convoluted tube?
This mechanism allows for an organism to return to normal after a change in the external or internal environment.
What is a negative feedback system?
These specialised cells detect changes in blood osmolality
What are osmoreceptors?
