Parts, Organs, and Functions of Farm Animals III

1. Skeletal System

The skeletal system provides structure and support to the animal’s body. It includes:

• Main Parts:
  • Bones
  • Joints
  • Cartilage

Functions of the Skeletal System:

• Supports the Animal Structure: The skeleton forms the framework that supports the body and protects vital organs.
• Facilitates Movement: The skeletal system works with muscles to enable movement.

2. Reproductive System

The reproductive system is essential for producing offspring. It consists of:

• Male Reproductive System:
  • Testes
  • Penis
  • Accessory glands
• Female Reproductive System:
  • Ovaries
  • Uterus
  • Vagina

Functions of the Reproductive System:

• Helps in the Production of Offspring: The reproductive system is responsible for the generation of new individuals through mating and breeding.
• Hormonal Regulation: It produces hormones that regulate reproductive cycles and characteristics.
