Stroke

Coronary artery disease

All of the above

Kidney disease

the baroreceptors increase their rate of firing.

heart rate decreases.

venous return of blood to their heart momentarily decreases.

diastolic blood pressure increases while systolic blood pressure falls.

All of the above

Increased activity of the sympathetic nervous system

Increased firing of baroreceptors

Redistribution of blood flow towards the intestines and kidneys

control the amount of salt and water that is lost or retained by the body.

are able to secrete adrenaline when blood pressure falls.

have stretch receptors that monitor the total blood volume.

are in direct communication with both the baroreceptors and the medullary cardiovascular centre.

Body temperature increases

All of the above

There is increased activity in the cardiac sympathetic nerves

There is reduced activity in the cardiac parasympathetic (vagal) nerves

an increased effort required for inspiration.

a decrease in the work of breathing.

a decrease in the number of small alveoli draining into large alveoli.

an increase in the compliance of the lungs.

arises when there is an imbalance between oxygen supply and demand.

Both (a) and (b) are true.

has little effect because the heart has sufficient ATP reserves to draw upon.

can give rise to chest pain known as angina.

The elastic recoil of the chest wall is abnormally high.

The magnitude of surface tension is the same in small and large alveoli and therefore the small alveoli do not collapse.

The lung compliance is abnormally increased.

The work of breathing is abnormally increased.

Capillary hydrostatic pressure is reduced

Capillary hydrostatic pressure is increased

Capillary oncotic pressure is increased

Capillary oncotic pressure is reduced

Narrowing of the main renal artery

Baroreceptor dysfunction

As yet unknown causes

A tumor in the adrenal gland
