What do you think will happen to the organism if the tissues were injured or diseased?

Answer 1

Tissues are made of similar cells all working together for a similar function. Organs are made of different tissues all working together. And, organ systems are made of different organs working together to make an organism work. So, if any of these stop working, you could say that all the 'levels of organization' will come tumbling down and the tissues won't be able to continue in a dead organism. Eventually all the anabolic processes will do catabolic and the organism will be reduced into organic waste in biological reductionism.

Answer 2

Cells

First line of defense is the cell(s). The cellular activity tries to wall off, contain, and repair damage, injury, or disease. Often, the cell can make sufficient repairs. Think of a cut on your finger, or someone having surgery. Macrophages from the cell speed to the area and begin clean up. This energy produces warmth at the site, calling on the body's defenses to bring more oxygen to the area, prevent or control infection, and begin rebuilding.

Tissues

Second, if the cellular level cannot keep up or stop the damage, part of the tissues will be sacrificed so the cells can keep the rest of the tissues healthy. For example, in a mild to moderate heart attack, a portion of heart muscle may not be repairable. Or, as another example, a portion of tissue may die but is walled off to protect the rest of the organ. If walled off or if tissue died, the smaller blood vessels will form new pathways going around the problem area so the rest of the organ still receives nutrients and oxygen.

Organs

Some organs, though, rely on having most of its tissue in good working order. The heart and kidneys are two examples of organs that need good-working tissues. So, third, IF enough tissue is affected by injury or disease, it will begin to compromise the full organ. This is where damage begins to cascade, like knocking over the first domino, which affects the second, and third, and so on. So for example, if a kidney is hit by a bullet, the other kidney tries to do the work of both kidneys. This increases stress on the heart if the working kidney cannot keep up. Same with chronic respiratory diseases; they add stress to the heart.

However, other tissues do not affect whole organs. For example, you can hurt, damage, or even remove part of a muscle in the leg. The leg will be damaged, but it won't affect the other primary tissues, organs, or organ systems. But let's say the injury to the leg muscle led to a blood infection, the infection circulating in the blood is harder for the body to control or fix. So what began as a problem with a muscle tissue now affects major organ systems; the person could even die

Organs

Every cell, tissue, and organ plays a key role in a very exact "choreographed dance" between the organ systems. If one part stumbles (gets injured) or messes up (gets diseased), every cell tries to rescue the tissue and the tissues try to rebuild and keep going with the "dance". But if enough tissue gets injured, it starts to affect the organ. (See last paragraph.)

Organ systems

When one organ fails, the other organs in the system try to compensate. Now, though, it gets trickier to keep everything going. Too much is happening all at the same time. Doctors can try to intervene-- for example, they might induce a coma and put a person on a ventilator so the patient gets maximum O2 without expending excess energy. This helps the body repair itself. Medications and supportive therapies can help, or perhaps surgery.

However, since the body is a dance between many working parts, significant damage in one organ affects the organ, which then affects the organ system....which then, affects almost all the major organs in other body systems! One system fails, and another system cannot do anything about it, because one organ system can give assistance to another system but cannot do the work of another system. For example, burns over a vast amount of body area will immediately affect multiple organs resulting in multiple organ / organ system failure.

Organism

We can live without some parts of some systems. For examples: blindness, deafness, paralysis, defective heart valves. We can live without parts altogether, like missing limbs, surgically removed ovaries or appendix, a surgically shortened intestine. We can live with outside assistance, like from medications, stomas, dialysis, pacemakers, or ventilators. But-- we cannot live without all of our key organs working at least somewhat. If one organ system goes afoul, it affects the next system, and so on. Eventually, even outside help cannot stop what is happening. The organism-- the human body-- will die.

These facts are why medical personnel are so concerned about things that cause major physical trauma, or lifelong disability and lifelong medical problems. Just SOME things they hope to stop are:

1. Drug use - We cannot live well if we mess up the Brain, Liver, and Kidneys. One instance of IV drug use can kill skin, damage the blood vessel, cause infection in the heart and body, or send air to the brain.
2. Smoking - We need our lungs.
3. Obesity and over-eating fatty foods - We need our hearts and blood vessels.
4. Drinking - The pancreas and liver are very important organs.
5. Diabetes - We must keep cells healthy, or multiple body system failures can result.
6. Drinking or Texting and Driving - Vehicle Traumas can cause death.
7. Guns! - Physical trauma is intense, often affecting multiple body systems within minutes.
8. Exercise and Good Nutrition - It affects ALL body systems.

Answer 3

It depends entirely on which tissues are injured or diseased. Some tissues are vital to the function of the entire organism, like heart tissue or spinal cord tissue. Others, like blood or skin, can be damaged and repaired quite easily. You'd have to look at your homework and see exactly which tissue is being discussed and ask that specific question here to get the correct answer.
