Explanation A fast run is a sign of physical activity. Any type of locomotion in an intense manner tends to stimulate the SNS (sympathetic nervous system) of the body. Activation of the sympathetic nervous system leads to an increase in the HR. The heart rate is increased as the number of beats per minute increases from the normal value...

Question

Chapter 17, Problem 15CYU

Summary Introduction

To review:

The reason for the increased HR (heart rate) and SV (stroke volume) after running fast for a while.

Introduction:

Heart rate is defined as the number of times the heart beats in a unit time. A normal person should have a heart rate between 60 to 100 BPM (beats per minute). The SV is defined as the amount of blood whichis pumped out through the ventricle after a contraction. The normal person should have the SV of 50mL (milliliters) to 120mL.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
