how do all the tissues work together to maintain homeostasis in a human body

Question

 i need an answer asap and it needs to be specific and have examples if possible 

 

Answer 1

As you've stated in your question, the tissues in the body work together and as a result homeostasis is maintained/obtained.  The tissues and organs of the body have different classes or levels of "hierarchy".  The hierarchy of tissues and organs in the body is as follows: Organelles > Cell > Tissue > Organ > Organ System > Organism (individual) > population.  Often, homeostasis is associated with body temperatures.  However, because homeostasis is known as the body's way of maintaining its internal balance and environment, then homeostasis can be maintained at different levels throughout the body, and it's organs.

 

For example, homeostasis is maintained in different ways among each of the organ systems. The lymphatic system uses it components; lymph, lymph nodes, and lymph vessels to defend against infection, disease, and also transfers lymph between tissues and the blood stream.  When the lymphatic system does not do this then homeostasis is considered to be unmaintained.

The digestive system is responsible for processing food in which nutrients, minerals, vitamins, and water are absorbed.  In the event that an influx of glucose were presented into you body and your pancreas started to function incorrectly (insulin isn't released) then the glucose you've ingested will not undergo reuptake by your cells and your liver.  Within the liver, when insulin is not being produced (which proper function), the liver converts glycogen into to glucose and blood glucose levels remain relatively constant-know as a homeostatic event.

 
 

At the cellular level -in particular multicellular organisms-their cells are surrounded by an internal environment of extracellular fluid, this means that the cell(s) is/are literally encompassed by extracellular fluid within the internal environment, right outside their surroundings.  I think a similar and familiar concept can be demonstrated by the "sodium-potassium" pump mechanism.  The sodium-potassium pump is responsible for generating a gradient of ions, in which it  continually pumps sodium ions out of the cell and potassium ions into the cell, powered by ATP.  For each ATP unit that is degraded 3 sodium ions move out of the cell and 2 potassium ions move into the cell. When sodium is diminished an electrical gradient is created; which aids in many tasks of the body.  Additionally a concentration gradient is also employed and contributes to many different functions.  Together the two allow for properties and events such as permeability in and out of cell membranes.

All, in all homeostasis is maintained at many different levels within the body and the systems/tissues often work synergistically to accomplish this. I hope this helps. If it's confusing, or makes no sense,or doesn't quite address the questions you've asked, please let me know.
