I acknowledge that I understand that by proceeding to complete this assessment I am agreeing to the above conditions.

-2- Answer Each question in the relevant section of the answer sheet provided. DO NOT respond with answers on this document.
Questions are: –

1.Explain the mechanism which results in the atria contracting slightly before the ventricles as part of the cardiac cycle. (Maximum word count = 100 words)

2.If you voluntarily hold your breath until you are compelled to take a breath, what is the stimulus that sets off the reflex pathway that eventually compels you to take a breath? How is the stimulus detected? Where is the integration centre for this reflex? What is the output signal? (Maximum word count = 30 words)

3.When blood arrives at the capillaries, why is plasma forced out of the capillary bed at the beginning (arterial end) and pulled back in at the end (venous end). Explain in detail the mechanism by which this occurs? (Maximum word count = 150 words)

4.What is venous return? Explain in detail the mechanism via which an increase in venous return affects stroke volume and cardiac output. (Maximum word count =150 words)

5.List 3 ways that carbon dioxide generated during cellular respiration is transported in the blood from cells to the alveoli of lungs. How are hydrogen ions transported inside the red blood cells? (Maximum word count = 20 words)

6.List the main steps in haemostasis. List these steps in the order in which they occur.Briefly explain why step one is required?(Maximum word count = 40 words)

7.Consider the equation below: –
CO2 +H2O  H2CO3  H +HCO3
If you blow through a straw into water containing pH indicator, you will witness the solution turning from a more neutral to a more acidic condition.Refer to the equation above to describe what happens in the solution as a result of blowing into it? (Maximum word count = 100 words)

8.The baroreceptor reflex is a fast-neural reflex that responds to changes in blood pressure (BP). When blood pressure increases, the baroreceptor reflex is activated. Explain in words what happens at each step of the baroreceptor reflex in order to achieve the overall response of decreased blood pressure. As part of your explanation, make sure you use physiological terminology to indicate the generic steps of a typical neural reflex- for example- Start with ‘the stimulus is increased blood pressure’.. etc…. (Maximum word count = 250 words)

9.Describe in detail the mechanism via which force of contraction is increased in skeletal muscles? How does this differ from the mechanism via which force of contraction is increased in smooth muscle cells?(Maximum word count = 200 words)

10.Explain how an increase in cellular metabolism affects blood flow to cells.
