When a red blood cell is placed in a hypertonic solution, it shrinks as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.Know More
The reason that blood cells change size when placed in solution with different salt concentration is due to the process of osmosis. Osmosis causes solutions with high salt concentrations to draw the water out of areas with low salt concentration.
There are a few exceptions to this phenomenon. Blood cells may draw water and burst when placed in a hypertonic solution under a few special occasions. Some diseases effect the structural integrity of blood cells. Additionally, when human blood cells are exposed to near freezing temperatures, they may draw water and burst.
Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, kidneys work by using osmotic principles. Kidneys filter an animal’s blood to remove excess salt and balance the amount of water in the animal.Learn More
The main function of white blood cells is to help protect the human body from infection as well as other foreign materials. White blood cells are also known as leukocytes, and they develop in bone marrow from stem cells.Full Answer >
A hypertonic environment is one in which the concentration of a solution's dissolved substance is greater than the concentration of the dissolved substance in the solution compared. If a cell is placed in a hypertonic environment, the cell membrane works to achieve equal concentrations on each side of the membrane.Full Answer >
In physical sciences, "hypertonic" means that a solution exhibits greater osmotic pressure compared to a another solution, especially one separated by a semipermeable membrane. That is, the concentration of a certain solute is greater in the hypertonic solution.Full Answer >
Red blood cells carry oxygen and nutrients to the tissues in the body and take away carbon dioxide. They are also called erythrocytes. They get their red color from a pigment called hemoglobin, and it is the hemoglobin that actually carries the oxygen and carbon dioxide.Full Answer >
