Question
Please answer these questions with brief explanation. Thank you.
1. imagine that at time 0 the diameter of the afferent and efferent arterioles are the same. Then, at time 1 the diameter of the afferent arteriole is 3x greater than the diameter of the efferent arteriole. Comparing time 0 to time 1, what change do you expect?
No change
At time 1, the hydrostatic pressure in the glomerulus will be much greater
At time 1, the hydrostatic pressure in the glomerulus will be much lower
2. According to Starlings Forces, what will happen if the hydrostatic pressure of the blood in a capillary increase?
More fluid will leave the capillary
Less fluid will leave capillary
3. According to Starlings Forces, what will happen if the osmotic pressure of the blood in a capillary decrease?
More fluid will leave the capillary
Less fluid will leave capillary
4. According to Starlings Forces, what is the main osmotic regulator of the blood?
Na+ ions
K+ ions
Cl- ions
glucose
plasma proteins
Na ions and K ions together
Explanation / Answer
1)At time 1 the hydrostatic pressure in the glomerules will be much lesser. The hydrostatic force is the physical force of a fluid. These is positive in the capillaries as the diameter increases the pressure is decreased.
2) Hydrostatic pressure is defined as the physical force of a fluid against their closed barriers.plasma that are present in the capillaries have a positive hydrostatic pressure.if hydrostatic pressure in the capillaries increased means more fluid can leave the capillaries.
3)The osmotic pressure is defined as the pressure generated by the protinaceous tissues. These is also called as the oncotic pressure.Generally the pressure inside the capillaries is high compared to outer side hence when an increase in the osmotic pressure more fluid leaves the capillaries.
4) Main osmotic regulators are the plama proteins the name itself indicating that the osmotic pressure is also called as oncotic pressure which is defined as the pressure due to protinacious tissue.
