NOTE

FUNCTIONS OF PARTS/ORGANS OF FARM ANIMALS

 Functions of the respiratory system

  1. The primary function of the respiratory system is to facilitate the exchange of oxygen and carbon dioxide between the animal's body and the external environment.
  2. The respiratory system enables the intake of oxygen through inhalation and the release of carbon dioxide through exhalation.
  3. Oxygen is transported from the lungs to the bloodstream, where it is then carried to the body's cells for cellular respiration.
  4. Carbon dioxide produced by cellular metabolism is transported from the bloodstream to the lungs for exhalation.

Functions of the nervous system

  1. The nervous system coordinates voluntary and involuntary actions of the body, allowing farm animals to move, respond to stimuli, and maintain balance.
  2. Nervous system receptors detect various stimuli such as touch, temperature, pain, and sound, enabling animals to perceive their environment.
  3. The nervous system integrates sensory information and processes it to generate appropriate responses, including reflex actions and complex behaviors.
  4. Nerves transmit signals between different parts of the body and between the body and the brain, facilitating communication and control.
  5. The nervous system helps regulate physiological processes such as heart rate, breathing, and digestion to maintain internal balance (homeostasis).

Functions of the circulatory system

  1. The circulatory system transports essential substances such as oxygen, nutrients, hormones, and waste products throughout the body.
  2. Oxygenated blood is pumped from the lungs to the tissues, where it is used for cellular respiration.
  3. Nutrients absorbed from the digestive system are carried by the circulatory system to cells and tissues for energy production and growth.
  4. The circulatory system collects metabolic waste products such as carbon dioxide and urea from cells and transports them to excretory organs for elimination.
  5. Blood circulation helps regulate body temperature by distributing heat produced by metabolism and facilitating heat exchange with the environment.

EVALUATION: 1. Mention 5 functions of respiratory system in farm animals
