Laboratory practical of chicken write procedures?

1. Obtain a fresh chicken from the refrigerator and place it on a clean dissection tray.

2. Put on gloves and safety goggles to protect yourself from any potential hazards.

3. Use a scalpel to make a midline incision along the abdomen of the chicken, starting from the breastbone and extending towards the vent.

4. Carefully cut through the skin and muscle layers to expose the internal organs of the chicken.

5. Identify and locate the major organs such as the heart, lungs, liver, kidneys, and intestines. Take note of their size, shape, and location within the body cavity.

6. Remove each organ one by one, being careful not to damage them. Examine each organ closely and note any abnormalities or differences in appearance.

7. Take measurements of the organs using a ruler or calipers, and record your findings in a lab notebook.

8. Dispose of the organs properly in a designated waste container.

9. Clean up the dissection tray and tools with soap and water, and disinfect them with a suitable disinfectant.

10. Wash your hands thoroughly with soap and water after completing the dissection.

11. Write a detailed report of your observations and findings from the chicken dissection, including any abnormalities or interesting discoveries.

12. Present your findings to your instructor or classmates, and be prepared to discuss your observations and conclusions.

Laboratory Practical: Chicken

Objective:

- To examine the external and internal anatomy of a chicken.
- To identify the major organs and structures of the chicken.

Materials:

- Freshly killed or preserved chicken
- Dissecting tray
- Dissecting tools (scalpel, scissors, forceps)
- Ruler
- Gloves

Procedures:

External Examination:

1. Wash your hands and put on gloves.
2. Place the chicken ventral side up on the dissecting tray.
3. Observe the overall shape and size of the chicken.
4. Note the presence of feathers, beak, comb, wattles, and feet.
5. Measure the length and width of the chicken.
6. Identify the following external features:
- Head: beak, eyes, nostrils, ears
- Neck
- Body: wings, tail, legs
- Ventral side: abdomen, cloaca

Internal Examination:

1. Skin and Body Cavity:

1. Use a scalpel to make an incision along the ventral midline, from the cloaca to the neck.
2. Carefully lift the skin to expose the body cavity.
3. Observe the organs within the body cavity: heart, lungs, liver, stomach, intestines.

2. Digestive System:

1. Identify the esophagus, stomach, small intestine, and large intestine.
2. Trace the path of food through the digestive system.
3. Examine the contents of the stomach and intestines.

3. Respiratory System:

1. Locate the trachea and lungs.
2. Observe the structure and function of the lungs.
3. Examine the air sacs in the body.

4. Circulatory System:

1. Identify the heart and major blood vessels.
2. Observe the structure and function of the heart.
3. Trace the flow of blood through the body.

5. Reproductive System:

- Identify the ovaries or testes.
- Observe the structure and function of the reproductive organs.

6. Muscular System:

- Identify the major muscles of the leg, wing, and chest.
- Observe the attachments and function of the muscles.

7. Skeletal System:

- Identify the major bones of the skull, spine, wings, and legs.
- Observe the structure and function of the bones.

8. Neural System:

- Identify the brain and spinal cord.
- Observe the structure and function of the neural system.

Report:
