The Secret Life of Plants
A vascular plant tissue which transports substances in one direction
What is xylem tissue?
Where hormones must travel through in order to reach their target cells
What is the bloodstream?
What is mechanical digestion?
The second component in a stimulus-response model
What is a receptor?
These small projections on the lining of the small intestine increase surface area for absorption
What are villi?
A long, thin extension which projects from some plant cells to increase the surface area for water absorption
What is a root hair?
A hormone released by beta cells of the pancreas to increase glucose uptake from the blood
What is insulin?
The chemical form in which humans excrete nitrogenous waste from the body
What is urea?
A process involving blood vessels which may be used in thermoregulation when body temperature is too high
What is vasodilation?
Mrs Farmer's favourite colour
What is blue?
A characteristic of water which describes how it likes to "stick" together
What is cohesion?
The hormone released by the pituitary gland in response to changing water levels in the body
What is ADH (antidiuretic hormone)?
The digestive fluid stored in the gall bladder which aids in digestion of fats
What is bile?
The main form in which the body stores glucose when blood glucose levels are high
What is glycogen?
This condition may be treated with radioactive iodine
What is hyperthyroidism?
Cells of the phloem which ensure sieve cells remain alive
What are companion cells?
The hormone released by the hypothalamus which acts on the pituitary gland as part of the overall regulation of the thyroid
What is TRH (thyrotropin-releasing hormone)?
The tangle of blood vessels in the nephron where initial filtration from the blood into the tubules takes place
What is the glomerulus?
A receptor which detects changes in blood volume and blood pressure
These regions of the pancreas contain cells which secret hormones
What are islets of Langerhans?
The pathway taken by the majority of nutrients and minerals absorbed from the soil by roots
What is the cytoplasmic pathway?
This hormone released by the kidneys in response to changing water levels stimulates a pathway to the production of another hormone
What is renin?
The endocrine glands which are found above the kidneys
What are adrenal glands?
A condition/malfunction in homeostasis which can be caused by liver disease
What is hypoglycaemia?
In vascular plants, this force helps water flow through narrow tubes due to the adhesion of liquid to the surface of the tubes
What is capillary action?
