When a white blood cells engulfs bacteria this is?
The process by which white blood cells surround, engulf and destroy foreign substances, is known as phagocytosis. These cells collectively are called phagocytes. Phagocytes eventually end up dying. Pus is made from dead tissue, bacteria, and live and deceased phagocytes.
What is the truth about a hypertonic solution, you ask?
If a cell is placed into a hypertonic solution it will result in a net flow out of the cell and a loss of volume. If the solution’s solute concentration is greater than the one inside the cell, the solution will be hypertonic. The solutes cannot cross the membrane.
How does diffusion work inside the body?
The concentration gradient is the difference in concentration. Diffusion is essential in the body’s ability to move substances, such as the movement oxygen from the blood into the blood and carbon dioxide from the blood into the lungs.
What is the significance of diffusion for living organisms?
Diffusion plays a vital role in the life of living organisms. It is necessary for both intake of useful materials as well as removal of waste. For instance, oxygen is necessary for bodily functions. However, carbon dioxide must be eliminated from the body.
What is the significance of diffusion and osmosis for a living organism?
Both osmosis and diffusion aim to balance forces within cells and organisms, spreading water, nutrients, and other chemicals from high-concentration areas to low-concentrations.
What are the factors that affect simple diffusion?
The rate of diffusion
|The temperature||The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly.|
|The surface area of the cell membrane separating the different regions||The greater the surface area, the faster the rate of diffusion.|
