Answer Key & Explanations:

Section 1: Animal Anatomy and Physiology

c) Fermentation of plant material: The rumen is the largest compartment of the ruminant stomach and is responsible for the microbial fermentation of ingested plant material.
b) Left atrium: The left atrium receives oxygenated blood from the lungs via the pulmonary veins.
Arteries: Carry oxygenated blood away from the heart; have thick, elastic walls to withstand high pressure. Veins: Carry deoxygenated blood towards the heart; have thinner walls and valves to prevent backflow.
A complete blood count (CBC) typically includes: Red blood cell count (RBC), white blood cell count (WBC), platelet count, hemoglobin concentration, hematocrit, and differential white blood cell count.

Section 2: Common Diseases and Treatments

Canine parvovirus: Clinical signs include severe vomiting, diarrhea (often bloody), lethargy, dehydration, and anorexia.
Bacterial infections: Caused by bacteria; often treatable with antibiotics. Viral infections: Caused by viruses; typically not treatable with antibiotics.
Common internal parasites in cats: Roundworms, hookworms, and tapeworms.
Rabies vaccination: Prevents the spread of a fatal viral disease affecting the central nervous system in mammals, protecting both animals and humans.

Section 3: Animal Husbandry

Rabbit housing: Requires a clean, dry environment with adequate ventilation, protected from extreme temperatures and predators. Sufficient space for movement and hiding places are also essential.
Balanced dog diet: Should contain appropriate amounts of protein, carbohydrates, fats, vitamins, and minerals, tailored to the dog's age, breed, and activity level.
Dental care: Regular brushing and professional cleanings prevent periodontal disease, which can lead to serious health problems.
Animal restraint: Methods include physical restraint (using hands, muzzles, etc.), chemical restraint (using tranquilizers or anesthetics), and environmental control (using a cage or other confinement).

Section 4: Ethical Considerations

Veterinarian's role: To provide high-quality medical care while prioritizing animal welfare and minimizing pain and suffering.
Euthanasia: Should be performed humanely, only when necessary to alleviate suffering and with the owner's informed consent.
Informed consent: Owners must be fully informed about the risks and benefits of any veterinary procedure before consent is obtained.
Veterinary technician's role: To uphold ethical standards by following established protocols, maintaining patient confidentiality, and reporting any concerns about animal welfare.

This detailed answer key provides a comprehensive understanding of the correct answers and the underlying principles. Remember that continuous learning and practice are crucial for success in your HOSA Veterinary Science competition.
