Parts, Organs, and Functions of Farm Animals I

1. Parts and Organs of Farm Animals

Farm animals have various systems that contribute to their survival and productivity. Key systems include:

• Digestive System:
  • Comprises organs such as the mouth, esophagus, stomach, intestines, and anus.
  • Responsible for breaking down food into nutrients for energy and growth.
• Respiratory System:
  • Includes the nose, trachea, lungs, and diaphragm.
  • Functions to supply oxygen for metabolic processes and remove carbon dioxide from the body.

2. Functions of Parts and Organs of Farm Animals

• Digestive System Functions:
  a. Breaks down food into metabolic nutrients.
  b. Absorbs nutrients and water necessary for bodily functions.
• Respiratory System Functions:
  a. Provides oxygen for metabolic processes.
  b. Facilitates the exchange of gases, ensuring efficient energy production.
