In the whole of the human body, the kidneys take about only 0.4% of the total body weight. Yet about 1.2 liters of the blood is received by the kidneys per minute. The renal artery nourishes both the kidneys. The renal artery is distributed into segmental arteries before arriving at the hilum. The segmental arteries give rise to interlobar arteries. These interlobar arteries breach both of the renal columns and journeys between the borders of cortex and medulla. This junction is called as the corticomedullary junction. The interlobar arteries gives off arcuate arteries, and it takes a 90° turn and moves at the base of the pyramid. Numerous cortical radiate arteries are given off by the arcuate arteries, which enters into the cortex. The afferent and efferent arterioles are raised at the cortex region.

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
