4000
Basal metabolic Rate BMR is best described as
The daily amount of energy required to maintain body function at rest
Type 2 diabetes characterised by
Insulin insensitivity and resistance
Which brain structure receives signals from leptin and ghrelin?
Hypothalamus
In a healthy individual, low levels of leptin in the bloodstream tell the brain that fat stores are:
Low and we are at risk of starvation
Using out past good behaviour as an excuse to indulge is an example of the:
Moral licensing effect
False statement about self-control?

Blood is supplied to the afferent arterioles by the…
Interlobular arteries
The portion of the nephron responsible for filtering the blood is the…
Glomerulus
Increases in both renal blood flow and glomerular filtration rate are caused by which of the following:
- dilation of efferent arterioles
- increased glomerular filtration co-efficient
- dilation of the afferent arterioles
- increased plasma colloid osmotic pressure
Increased glomerular filtration co-efficient
Dilation of afferent arterioles

- all of the above
All of the above
What happens in the proximal convoluted tubule?
Reabsorption
Which statement about the juxtaglomerular apparatus is incorrect?
- high Na+ concentration in the filtrate can inhibit the secretion of renin
- the macula densa cells of the distal convoluted tubule secrete renin
- the macula densa cells of the distal convoluted tubule secrete an unknown substance
- it is a location in each nephron where the afferent arteriole and the distal convoluted tubule contact each other
The macula densa cells of the distal convoluted tubule secrete renin
