A hypertonic solution will cause the cell to shrink as water leaves the intracellular fluid due to osmosis. A hypotonic solution will lead to water crossing into the cell membrane, causing it to swell, leading to hemolysis.

Breakdown of recipient's red blood cells when incompatible bloods are mixed?
agglutination
Alpha hemolytic reaction in blood agar culture?
Alpha hemolytic reaction in blood agar culture is characterized by partial hemolysis of red blood cells, forming a greenish discoloration around bacterial colonies. This is commonly seen with organisms like Streptococcus pneumoniae, which release hydrogen peroxide that causes the partial breakdown of red blood cells. Alpha hemolysis is distinguished from beta hemolysis (complete lysis of red blood cells) and gamma hemolysis (no hemolysis).
What type of tonicity will draw water from red blood cells or Elodea cells?
Salt/Salt Water
When blood is collected from patient serum should be separated from cells as quickly as possible to avoid?
hemolysis
What is the purpose of stabbing into the blood agar?
Streak stab is most commonly used when inoculating blood agar with hemolytic bacteria. The stabs expose the bacteria to a greater surface area of blood cells and will enhance the hemolysis effect.
What are effects of toxicity on hemolysis of red blood cells?
Toxicity can lead to hemolysis, the destruction of red blood cells, by damaging the cell membrane and causing it to rupture. This can result in the release of hemoglobin into the bloodstream, leading to anemia and potential organ damage. Additionally, toxic substances can interfere with the normal function of red blood cells, affecting their ability to carry oxygen to tissues in the body.
What effects does a hemotoxin snake venom have on blood?
Hemotoxin snake venom leads to hemolysis which is destruction of the red blood cells.
What are the principle of hemolysis?
Hemolysis refers to the rupture or destruction of red blood cells. The three main mechanisms of hemolysis are osmotic, mechanical, and immune-mediated hemolysis. Osmotic hemolysis occurs when red blood cells swell and burst due to changes in osmotic pressure, mechanical hemolysis involves physical damage to red blood cells, and immune-mediated hemolysis is caused by the immune system attacking and destroying red blood cells.
Difference between alpha and beta hemolysis?
Alpha hemolysis is partial hemolysis of red blood cells resulting in a greenish discoloration around bacterial colonies on blood agar. Beta hemolysis is complete hemolysis of red blood cells resulting in a clear zone around bacterial colonies on blood agar. This distinction is important for identifying bacteria and determining their pathogenicity.
What is the meaning of hemolysis?
Insufficient red blood cells
What is the destruction of red blood cells that results in the liberation of hemoglobin?
Hemolysis is the destruction of red blood cells or Erythrocytes with a release of hemoglobin that diffuses into the surrounding fluid.
Breakdown of recipient's red blood cells when incompatible bloods are mixed?
agglutination
What is the medical term meaning destruction of red blood cells?
Hemolysis is the breakdown of red blood cells. = hemo (blood/hemacyte) + lysis (to separate/breaking down of/destruction)
What type of tonicity will draw water from red blood cells or Elodea cells?
Salt/Salt Water
When red blood cells draws in water and bursts it is said to undergo?
When red blood cells draw in water and burst, this process is called hemolysis. Hemolysis can occur due to various factors such as osmotic imbalances, toxins, or physical damage to the cell membrane.
What ruptures red blood cells and bursts vessels?
The process that cause red blood cells to rupture and vessels to burst is hemolysis. Hemolysis can result from various factors such as infections, immune reactions, certain medications, or inherited disorders. When red blood cells rupture, they release hemoglobin and other cellular contents into the bloodstream, which can lead to complications such as anemia and organ damage.
What causes the destruction of red blood cells?
hemophagia
