Abdomen
The main trunk of the body is divided into two main parts:
the thorax and the abdomen. The abdomen lies below/behind the diaphragm and
the ribcage. This region is also known as the "belly" or "stomach" and it
holds the stomach, kidneys, intestines, and the liver.
Abscess
A localized collection of pus formed by the disintegration
of nearby tissue. This is frequently associated with infection.
Acute

Allergen
A compound that is foreign to the body and potentially causes an improper
immune response known as an "allergic reaction."

Anemia
A decrease in the number of red blood cells below normal values. Usually when red blood
cells are being lost or destroyed faster than they are created.
Antibiotics
A class of medications used to fight infections in or on the body. Penicillin is a well known

The mammalian heart has four chambers, two ventricles and
two atria (plural of atrium). The two upper chambers are known as the left

rest of the body and contracts to fill the right ventricle. The left atrium
accepts blood inflow from the lungs and contracts to fill the left ventricle.

A series of blood tests performed on one blood sample to analyze

A small tube connecting the tympanum (ear drum) to the outer
ear. It carries sound to the ear drum.
Echocardiogram
An advanced imaging technique using ultrasound to investigate
problems of the heart. It is noninvasive and unlike a radiograph (x-ray),
allows the veterinarian to view the heart contracting in real time and measure
blood flow, chamber pressure, and many other detailed aspects of the heart.

of the body contains the heart and lungs.

promote and immune response in the body. Ultimately, the body's reaction to the vaccine should
