Parts, Organs, and Functions of Farm Animals IV

1. Digestive System

The digestive system is responsible for breaking down food into nutrients that can be absorbed. It includes:

• Main Parts:
  • Mouth
  • Esophagus
  • Stomach
  • Intestines (small and large)
  • Anus

Functions of the Digestive System:

• Digests Food: The digestive system breaks down food into metabolic nutrients.
• Absorbs Nutrients: It absorbs essential nutrients for energy and growth.

2. Respiratory System

The respiratory system is vital for gas exchange in farm animals. It includes:

• Main Parts:
  • Nose
  • Trachea
  • Lungs
  • Diaphragm

Functions of the Respiratory System:

• Provides Oxygen: Delivers oxygen for metabolic processes.
• Removes Carbon Dioxide: Eliminates waste gases produced during metabolism.

3. Nervous System

The nervous system controls body functions and responses to stimuli. It includes:

• Main Parts:
  • Brain
  • Spinal cord
  • Nerves

Functions of the Nervous System:

• Enhances Stimuli: Processes sensory information and coordinates responses.
• Regulates Body Functions: Controls involuntary functions such as heart rate and digestion.

4. 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:

• Produces Offspring: Responsible for the generation of new individuals.
• Hormonal Regulation: Produces hormones that regulate reproductive cycles.
