Q
Describe hypovolemic shock
A
There is a low blood volume. This is can be non-haemorrhage for example sweating (not through bleeding) or haemorrhage for example ruptured blood vessels (bleeding). As little as 20% of the blood volume is able to induce this shock. Blood pressure will go down. There is reduced mixed venous oxygen saturation. The skin will appear cold and clammy as there is less blood flow to the tissues.
11
Q
Describe cardiogenic shock
A
This is where the left ventricle fails to pump a sufficient amount of blood around the body. This is common after a heart attack. There is reduced mixed venous oxygen saturation and reduced blood pressure. Due to the reduced blood flow to the tissues, the skin will appear cold and clammy.
12
Q
Why is hypovolemic and cardiogenic shock also known as ‘cold shock’?
A
There is reduced blood flow to the tissues creating a cold feeling.
13
Q
Which types of shock are described as distributive?
A
Septic, Neurogenic and Anaphylactic
14
Q
What happens to the blood vessels during distributive shock?
A

15
Q
During distributive shock, what causes the perfusion to vital organs to decrease?
A
Increased vasodilation, Increased permeability and increased microvascular clotting
16
Q
Why does distributive shock lead to warm and flushed skin?
A
There is increased blood supply to the peripheral vessels
17
Q
Why is the mixed venous oxygen saturation normal or increased with distributive shock?
A
Due to widespread vasodilation, there is very low vascular resistance. The blood flow is too fast to unload oxygen into the tissues
18
Q
Describe Septic shock
A
This is caused by a bacterial infection.
The endotoxins (lipopolysaccharides) present on the cell membrane of gram negative bacteria cause many effects.
- they break down the endothelium and cause the release of vasodilators (nitric oxide)
- they activate complement which causes mast cells to release histamine (vasodilator)
- they activate macrophages and neutrophils and they release pro-inflammatory cytokines for example IL-1 and TNF
- the endothelium will release tissue factor and this, in combination with a decrease in anti-coagulants, will cause an increase in blood clotting
The inflammatory molecules will cause breakdown of the vessel wall and this will lead to leaky vessels.
19
Q
Describe Anaphylactic shock
A
This is a severe allergic reaction and where there is a dangerously low blood pressure.
20
Q
Describe Neurogenic shock
A
This is where there is a failure of the CNS and it is unable to control the blood pressure and hence it is very low.
21
Q
Describe four things that happen when platelets become activated i.e when they bind to collagen on the vessel wall
A
- they change shape from sphere to cylindrical
- they change the gIIb/IIIa receptor which increase the affinity for fibrinogen and this allows a fibrin mesh to form
- they release negative molecules for example phosphatidylserine which binds to calcium and causes a negative surface to be formed to allow clotting factors to bind
- they release thromboxane A2 which allows platelet aggregation

This is innervated by the pudendal nerve and this is somatic (voluntary). This releases acetylcholine and this causes contraction, allowing us to hold in urine.
80
Describe what happens during an empty bladder
There is less stretching and the sensory pelvis nerve only sends out slow impulses to sacral region. This will stimulate the hypogastric nerve to causes detrusor relaxation and internal sphincter contraction. The pons helps to maintain the hypogastric nerve. The pudendal nerve is activated so urine can be held in.
81
Describe what happens during an full bladder
There is increased stretching of the detrusor muscle. The pelvic nerve will therefore increase the rate of fast-firing neurons to the sacral region. The signals go to the pons area and this causes:
- inhibition of the sympathetic hypogastric nerve (there is no relaxation of detrusor and internal sphincter relaxation)
- the pelvis efferent nerves are stimulated and this causes contraction
- there is inhibition of the pudendal nerve and this causes relaxation of the external sphincter

Describe the process of hearing
* Waves are transported trough the external and middle ear to the auditory recepotrs
* Waves are directed by the auricle through he external acoustic meatus to the tympanic membrane
* Ossicles transmit the vibration. This magnifies up to x22 due to the size difference.
* The stapes is connected to the oval window and this causes the perilymph to vibrate.
* The tectorial membrane will start to move and this is transmitted through to the basilar membrane
* The sterocilia start to move
* The mechanically-gated channels are connected by tip-link proteins. Potassium channels open and this causes depolarization. This causes calcium release and this forms a neurotransmitter.
* This travels via the cochlear nerve to the cochlear nucleus in the medulla oblongata. This will then reach the thalamus and then to the primary auditory centre in the temporal lobes.

Describe some changes of the cardiovascular system that occurs dirge exercise
Overall, the vasodilation of the skeletal muscles, heart and skin with exercise overrides the vasoconstriction of the kidneys and gastrointestinal organs to give an overall decrease in total peripheral resistance. MAP is a product of cardiac output and total peripheral resistance. Although total peripheral resistance has decreased, cardiac output increases to a greater extent so this has the effect of increasing MAP (but only by a small amount). Pulse pressure, however, increases significantly because an increase in both stroke volume and the speed at which the stroke volume is ejected result in a significant increase in systolic pressure.
