Question about osmotic pressure of blood plasma

In summary, osmotic pressure of blood plasma is the pressure exerted by the solutes in the blood plasma on the blood vessel walls. It is measured using an osmometer and is affected by the concentration of particles in the plasma and changes in the amount of water. Maintaining a proper osmotic pressure is important for maintaining the balance of fluids in the body and ensuring cells receive necessary nutrients and oxygen while removing waste products. If the osmotic pressure is too high or too low, it can lead to dehydration or cell damage.

The Attempt at a Solution



I'm guessing the correct answer is (c) equal to 21.
Something like (20+1)-(?-0)... Am I on the right track, or completely wrong?

1. What is osmotic pressure of blood plasma?

Osmotic pressure of blood plasma is the pressure exerted by the solutes (particles) in the blood plasma on the blood vessel walls. It is a measure of the amount of solutes in the blood plasma and is an important factor in maintaining the balance of fluids in the body.

2. How is osmotic pressure of blood plasma measured?

Osmotic pressure of blood plasma is typically measured using a device called an osmometer. This device measures the osmolality of a sample of blood plasma, which is a measure of the concentration of particles in the plasma. The higher the osmolality, the higher the osmotic pressure.

3. What affects the osmotic pressure of blood plasma?

The osmotic pressure of blood plasma is affected by the concentration of particles (such as electrolytes, proteins, and other solutes) in the plasma. It can also be affected by changes in the amount of water in the plasma, which can be influenced by factors such as hydration levels and kidney function.

4. Why is osmotic pressure of blood plasma important?

Osmotic pressure of blood plasma is important for maintaining the proper balance of fluids in the body. It helps to regulate the movement of water between the blood vessels and the surrounding tissues, ensuring that cells receive the necessary nutrients and oxygen while waste products are removed efficiently.

5. What happens if the osmotic pressure of blood plasma is too high or too low?

If the osmotic pressure of blood plasma is too high, it can cause water to move out of the cells into the blood vessels, leading to dehydration and potentially damaging the cells. If the osmotic pressure is too low, water can move into the cells, causing them to swell and potentially leading to cell damage. Maintaining a proper osmotic pressure is crucial for overall health and proper functioning of the body.
