How blood changes as a result of moving through pulmonary capillaries compared to blood moving through the capillaries of the nephron? Need anatomical differences in the capillaries and/or capillary beds (pulmonary versus nephron), and physiological changes that blood experiences (ex: pH, respiratory gases,etc).

Expert Solution

The blood in nephron passes in the closed capillary network around nephron with the three processes filteration , absorption and secretion which leads to concentration gradient creation and urine gets concentrated at the end. The nutrients are reabsorbed and urea is secreted in the fluid .

Whereas in pulmonary capillary gaseous exchange takes place due to partial pressure of Carbon dioxide and oxygen and this way ventilation takes place. At this place carbon dioxide is taken from tissues and oxygen is transported in the blood.

Pulmonary capillary network	Nephron capillary network
1)The pulmonary capillaries exit into the venules .	1)The glomerular capillaries exit into efferent arterioles.
2)The primary function is gaseous exchange in the blood.	2)The primary function is filteration of waste from the blood and produces urine.
3) Average diameter of pulmonary capillary - 6micrometers	3) Average diameter of nephrotic capillaries vary but is approximately 20 nm
4)These capillaries run around alveoli which is unit for gaseous exchange in respiration.	4)These peritubular capillaries are arranged around the nephron which is functional unit of kidney and removal of waste via urine.

Compared to normal blood flow velocity, v0, what is the velocity of blood as it passes through this blockage?

Arteriosclerotic plaques forming on the inner walls of arteries can decrease the effective cross-sectional area of an artery. Even small changes in the effective area of an artery can lead to very large changes in the blood pressure in the artery and possibly to the collapse of the blood vessel. Imagine a healthy artery, with blood flow velocity of v0=0.14m/s and mass per unit volume of ρ=1050kg/m3. The kinetic energy per unit volume of blood is given by K0=12ρv20. Imagine that plaque...
