Embark on an in-depth exploration of cat dissection labeled arteries and veins, a fundamental aspect of veterinary anatomy. This comprehensive guide provides a detailed overview of the dissection procedure, anatomical structures, and physiological significance of the circulatory system in felines.
Through meticulously labeled diagrams and a step-by-step approach, this guide empowers students to confidently identify and understand the intricate network of arteries and veins that sustain feline life.
Materials
To perform the cat dissection, the following materials are required:
- Preserved cat
- Dissecting tray
- Dissecting tools (scalpel, scissors, forceps)
- Pins
- Gloves
- Apron
- Safety glasses
- Colored thread or suture
Procedure
| Step | Description | Arteries | Veins |
|---|---|---|---|
| 1 | Make a midline incision along the ventral surface of the cat. | – | – |
| 2 | Reflect the skin and superficial fascia to expose the underlying muscles. | – | – |
| 3 | Identify the major arteries and veins of the cat. | – | – |
| 4 | Label the arteries and veins using colored thread or suture. | – | – |
| 5 | Carefully dissect away the muscles to expose the underlying organs. | – | – |
Arteries
| Name | Location | Function |
|---|---|---|
| Aorta | Dorsal to the heart | Supplies oxygenated blood to the body |
| Carotid artery | Neck | Supplies oxygenated blood to the brain |
| Subclavian artery | Thoracic cavity | Supplies oxygenated blood to the forelimbs |
| Celiac artery | Abdominal cavity | Supplies oxygenated blood to the digestive organs |
| Renal artery | Abdominal cavity | Supplies oxygenated blood to the kidneys |
Veins
| Name | Location | Function |
|---|---|---|
| Vena cava | Dorsal to the heart | Collects deoxygenated blood from the body |
| Jugular vein | Neck | Collects deoxygenated blood from the brain |
| Subclavian vein | Thoracic cavity | Collects deoxygenated blood from the forelimbs |
| Hepatic portal vein | Abdominal cavity | Collects deoxygenated blood from the digestive organs |
| Renal vein | Abdominal cavity | Collects deoxygenated blood from the kidneys |
Question Bank: Cat Dissection Labeled Arteries And Veins
What is the significance of labeling arteries and veins during cat dissection?
Labeling arteries and veins during cat dissection is crucial for accurately identifying and understanding the anatomy of the circulatory system. It allows students to visualize the pathways of blood flow, trace the distribution of oxygen and nutrients, and comprehend the physiological mechanisms that maintain homeostasis in cats.
How does the arterial system differ from the venous system in cats?
The arterial system carries oxygenated blood away from the heart to various tissues and organs, while the venous system returns deoxygenated blood back to the heart. Arteries typically have thicker walls and narrower lumens compared to veins, reflecting their role in maintaining higher blood pressure for efficient oxygen delivery.
What are some of the major arteries and veins in cats?
Major arteries in cats include the aorta, carotid arteries, and femoral arteries, which supply blood to the body, head, and hindlimbs, respectively. Major veins include the vena cava, jugular veins, and hepatic veins, which collect deoxygenated blood from the body, head, and liver, respectively.
