Veterinarian comes from the Latin word veterinarius
meaning "of or having to do with beasts of burden".

Do you enjoy impressing your friends with new and unfamiliar words? Or do you want to just understand what your vet is talking about. We've got vet vocab to help you talk the talk.

Acetabulum: The femoral head fits into this rounded portion of the pelvis to form the hip joint.
ALK Phosphatase: A liver enzyme. A blood test called a Serum Chemistry Profile checks the levels of this enzyme; if the levels are higher than normal, this could mean that the patient has liver disease.
ALT: A liver enzyme. Higher than normal levels mean the patient may have liver disease.
Aorta: A large blood vessel that delivers blood high in oxygen from the heart to the rest of the body. The aorta is the largest artery in an animal's body. The left ventricle pumps blood that is high in oxygen to the rest of the body through the aorta.
Anesthesia: A drug that causes an animal to lose consciousness and not feel pain during a surgical procedure.
Artery: An artery is an elastic vessle that carries blood away from the heart. Arterial blood is rich with things the body needs, such as oxygen and nutrients.
Atria: The atria are the chambers of the heart which receive blood and pump it into the ventricles. There is a left atrium and a right atrium.
Bladder: The organ that acts as a reservoir for urine.
Blood: Blood is a fluid that transports oxygen and nutrients to all parts of an animal's body. It also serves to carry away waste products. Blood is composed of a solid portion consisting of blood cells and platelets, and a fluid portion called plasma.
Blood Gas Analysis: This is a test that evaluates the respiratory system of the patient. It analyses arterial blood and records pH, bicarbonate, oxygen, and carbon dioxide levels.
Blood Vessel: One of the many "pipes" in the body through which blood flows.
CanineTeeth: The four large, pointed teeth.
Carbon Dioxide: A gas byproduct of metabolism that is removed from the blood by the lungs.

Chemosis: Accumulation of fluid in the pink tissues (conjunctiva) surrounding the eye, giving it a puffy appearance.
Complete Blood Count (CBC): This is a series of tests that evaluates red blood cells, white blood cells, and platelets. This can quickly tell a veterinarian whether a patient has a variety of problems including anemia, an infection, or a bleeding disorder.
Cornea: The transparent outer portion of the eyeball that covers the pupil and iris and lets light into the eye.
Corneal Fibrosis: The formation of scar tissue on the cornea in response to injury or chronic disease. This gives the cornea a white-gray color in the damaged areas.
Diabetes: A disease caused by the failure of an animal's pancreas to produce insulin. Insulin is a hormone that allows blood sugar (glucose) to be utilized by cells.

Globulin: A type of protein in the blood.
Heart: The heart is a pump which circulates blood through an animal's body. The heart has four separate sections called chambers. The heart also has a left side and a right side. The two smaller chambers on the top of the heart are called the left atrium and the right atrium. The two larger, more muscular chambers at the bottom of the heart are called the left ventricle and the right ventricle.
Hormone: A hormone is a chemical which serves as a messenger or as a regulator of a process in the body.
Humerus: The longest bone of the forelimb; it extends from the shoulder to the elbow.
Increased Respiratory Rate: Many things can cause an animal to breath faster than normal. These include excitement, pain, lung diseases such as pneumonia, and heart diseases.
Inflammation: The body's response to an infection. It can result in pain, redness, swelling, heat, or loss of function.
Iris: The colored part of the eye. In the middle of the iris is a black opening called the pupil. Muscles attached to the iris can make the pupil larger or smaller.
Kidney: These organs filter the blood and form urine. They also control the blood levels of some chemicals such as sodium, hydrogen, and potassium.
Large intestine: This structure is also called the colon and is responsible for the formation and storage of feces, and the absorption of water.
Left Atrium: Blood from the lungs that is high in oxygen flows through the pulmonary veins and into the left atrium.
Left Ventricle: The left ventricle receives blood from the left atrium and pumps in into the body through the aorta.
Lens: The part of the eye that serves to focus incoming light on a specific area on the retina.
Lens Luxation: Displacement of the lens out of its normal position in the eye.
Liver: This organ has a variety of functions including digestion, metabolism, and detoxification.
Lungs: The lungs are organs in the chest which serve to add oxygen to and remove carbon dioxide from the blood.
Mandible: The lower jaw bone.
Maxilla: The upper jaw bone.
Metabolic: Having to do with an animal's metabolism, which is the sum of all the chemical and physical processes in the body used to make and utilize energy.
Metacarpal Bones: Similar to a person's palm, these are the bones between the wrist and the toes.
Murmur: An abnormal heart sound that is caused by blood flowing in the wrong direction.
Metatarsal Bones: These are the bones between the ankle joint and the toes.
Nonresponive Pupil: Normally, the pupil should constrict when you shine a light on it, and dilate in the dark. When the pupil does not respond, this indicates damage to the eye, and possible loss of vision.
Olecranon: Part of the ulna which forms the "point" of the the elbow.
Optic Nerve: A nerve that carries impulses from the retina to the brain to form an image.
Oxygen: A gas that is used by cells in the body for the process of metabolism. The lungs serve to add oxygen to the blood through respiration.
