REPRODUCTIVE SYSTEM
The reproductive system includes all the organs and tissues concerned with reproduction in animals. Reproduction is the ability in animals to give birth to young ones. The purpose of reproduction is to ensure continuity of life.
Functions of the Reproductive System
(I) It ensures the continuity of species by gamete for motion, coitus, mating or servicing.
(ii) It ensures the formation of eggs and spermatozoa (sperm cells).
(iii) It ensures the production of reproductive hormones.
GENERAL FUNCIIONS OF PARTS AND ORGANS OF FARM ANIMALS
The general functions of the parts and organs of farm animal are the following:
(1) The Breakdown of Food into Metabolic Nutrients: The digestive system do help to break down food susbtances into metabolic nutrients in the body to be
(2) Provision of Oxygen for Metabolic Process: The respiratory system also helps to provide oxygen necessary for must metabolic processes in the body.
(3) Enhancement Stimulus: The nervous 2system and the skin, tougue, eye, ear,etc. enhance stimulus of some parts of the body to certain sensations.
(4) Provision of Blood to all Parts of the Body: The circulatory system helps to to provide blood to all parts of the body.
(5) Supporting the Animal Structure: The skeletal system also helps to support the animal structure.
(6) Helping in the Production of Offspring: The reproductive system also assists in the production of offspring.
