Parts, Organs, and Functions of Farm Animals II

1. Nervous System

The nervous system is crucial for controlling and coordinating the activities of farm animals. It includes:

• Main Parts:
  • Brain
  • Spinal cord
  • Nerves

Functions of the Nervous System:

• Enhances stimulus response: It processes information from sensory organs and triggers reactions to environmental changes.
• Coordinates body functions: It allows communication between different parts of the body, ensuring efficient functioning.

2. Circulatory System

The circulatory system is responsible for transporting blood throughout the body. It consists of:

• Main Parts:
  • Heart
  • Blood vessels (arteries, veins, capillaries)
  • Blood

Functions of the Circulatory System:

• Provides blood to all parts of the body: Delivers oxygen and nutrients to tissues while removing waste products.
• Maintains homeostasis: Regulates body temperature and pH levels, ensuring a stable internal environment.
