What happens when gamma rays strike living tissue?
When a gamma ray strikes living tissue (as when it strikes any matter) it deposits energy through excitation and ionization of the tissue's atoms and molecules. Since most of the matter in tissue is water, this mostly happens to water molecules. This creates free radicals (such as hydroxyl radicals), hydrogen peroxide, etc. These can then damage biological molecules such as DNA and this is known as an indirect effect. The gamma ray can also excite or ionize biological molecules directly.
3 factors that contribute to how much damage is done to living tissue by radiation?
Type of radiation: Different types of radiation (such as alpha, beta, gamma) have varying levels of energy and ability to penetrate living tissue. Dose received: The amount of radiation absorbed by the tissue, measured in Grays (Gy), determines the extent of damage. Higher doses typically cause more damage. Sensitivity of tissue: Some tissues in the body are more sensitive to radiation damage than others, such as rapidly dividing cells like those in the bone marrow or gastrointestinal tract.
How can ionizing radiation damage tissue?
Ionizing radiation can damage tissue by breaking chemical bonds in molecules, leading to the formation of free radicals, which can cause further damage to cells and DNA. This damage can disrupt cell function and may lead to cell death, mutations, or cancer. Additionally, ionizing radiation can directly affect ion channels and enzymes in cells, altering their normal function.
Can infrared light cause harm to living tissue?
Infrared light, when used in moderation, typically does not harm living tissue. However, prolonged exposure to high-intensity infrared radiation can cause burns and damage to the skin. It is important to regulate exposure levels to ensure safety.
Why does a sheet of tissue paper rise when you blow air above the tissue paper?
Tissue paper is not very dense. I assume it is one piece and is on a flat surface. When blowing down straight and in the middle, air is able to move through the tissue paper because it is porous. You keep forcing air down and the molecules are bombarding each other and when completely through the tissue paper the fastest way to escape and allow the other molecules through is by escaping under the tissue paper and outwards. This is what lifts the tissue paper.

What do gamma rays damage?
Any tissue they pass through.
Is Brownian movement peculiar to living tissue?
Yes, Brownian movement is peculiar to living tissue. It is the random movement of microscopic particles caused by the direct impact with the molecules of surrounding also called molecular movement.
Are boa constrictors poison?
No, they kill they're prey by constriction.

What will happen in certain tissues without tight junctions?
Without tight junctions in certain tissues, there would be a large amount of molecules freely flowing around the epithelial tissue. These junctions keep the cells in there safe from flowing through the epithelium.
What is the most common necrosis?
Necrosis is tissue death. It is common to find necrosis in the extremities, however necrosis can result from damage or disease in any living tissue or body part.
