Often it is common to know what organ system is involved in a disease and want to know some of the possibilities. Our lists are not meant to be complete groupings of the only possible diseases afflicting an organ system but they do provide a starting point for one's research. Here, we list diseases categorized by their organ system.
Tumors grow when cells "go wrong." Sometimes a virus is the inciting agent, sometimes it might be a chemical or environmental factor, or even a combination of exposures. Tumors can be benign or malignant depending on how "out of control" their growth becomes. We have a growing list of common tumor types and topics to help a pet owner understand their options.
The Digestive System is responsible for receiving nutrients, breaking them down, and presenting them to the circulation for absorption and processing. The tract can fall victim to parasitism, viral or bacterial infection, foreign body ingestion, and plenty more. Here are a sampling of topics.
Endocrinology is the study of hormones and how they control our different body systems. Unfortunately sometimes hormone balance goes wrong and when that occurs disease results. Here we review common hormone imbalances of our pets.
The cardiovascular system concerns the circulation of oxygen from lung to tissue and the transport of waste gases (carbon dioxide) from the body's tissues back to the lung. The heart is the "star of the show" but other players such as the veins, arteries, and capillaries should not go unappreciated. Here are some topics that concern problems that can occur in this system.
The urinary tract provides a means by which our daily metabolic wastes and toxins are filtered from our blood (by the kidneys), dissolved in as little water as possible (also by the kidneys), transported to a storage area (namely the urinary bladder), and removed from our bodies (by the process of urination. Disease can occur at any level of this system. Here are some relevant topics.
Our bones support the structures of our bodies and our joints allow us the flexibility and comfort of motion. As with any other system of the body, things can go wrong. We invite you to browse our growing list of topics.
In a world where pet over-population leads to the daily loss of thousands of dogs and cats, an understanding of animal reproduction and of responsible breeding is crucial. There is no disease process that kills pets in numbers to match the loss of the unwanted pets in pounds and shelters in this country. Here is a growing list of topics concerning pet sterilization, and breeding animals in an informed way.
The respiratory system brings oxygen in and breathes carbon dioxide out. Sounds simple but, in fact, there is quite a bit to it. Air must be filtered, warmed, and moistened in the sinuses and upper airways before entering the final tiny lung chambers (called "aleveoli") for gas exchange. Disease can develop anywhere along the pathway. Here is our list of topics so far.
The central nervous system includes the brain and the spinal cord. The peripheral nervous system includes the nerves running through the body instructing muscle in both voluntary and involuntary actions. Any of these areas can be stricken with disease. Our list is ever expanding. Here is our current sampling.
Skin can be stinky, itchy, dandruffy, or even balding. There are parasites, hormone problems, allergies, infections and more and don't forget that the ear is an extension of the skin. Here is our list of topics so far.
