Objective 7: Analyze factors that can affect cellular activities

To be honest, I'm not quite sure what the exact answer to this objective might be. It is such a broad objective that it could probably go in any direction. The body is an amazing, complex system! It consists of quite a number of unique systems, organs, tissues, hormones, cells and process that work together to achieve and maintain homeostasis. If even one of these systems, or even tissues for that matter, malfunctions in the slightest way our body could be thrown out of homeostasis. There are countless factors that could affect the body negatively, which could affect the body and its cellular activites. Since there is seems to be no right or wrong answer in an objective as broad as this one, I decided to list some of the factors that we've learned in our class that could throw off the bodies homeostasis. Here goes nothing!

Excess water in the body
Hormonal Imbalances
Bacterial or Viral Infections
Auto-immune diseases
Hypersecretion of a hormone
Hyposecretion of a hormone
High blood pressure
Organ failure
Blockage of an artery or vein
Low blood pressure
Respiratory Alkalosis/ Acidosis
Metabolic Alkalosis/ Acidosis
Carbon monoxide poisoning
Hormonal Imbalances
Sexually Transmitted Diseases
Changes in pH
Urinary Retention
Changes in Osmolarity

The list of factors that can affect cellular activities of the body could go on forever. I decided to list just a few of the topics that we have covered in class that can cause the body fall out of homeostasis. I could go on for days just listing factors, but I'm sure I've hit a few key points. The body has amazing systems and process that can detect fators such as these and respond to them in their own unique way to bring the body back to homeostasis.
