Step 1
Omasum and abomasum
Answer
The omasum is the third compartment of the ruminant stomach, which primarily functions to absorb water and some nutrients from the digestive contents. In contrast, the abomasum is the fourth compartment, often referred to as the true stomach, where the process of digestion is completed with the aid of digestive enzymes and acids.
Step 2
Ureter and urethra
Answer
The ureter is a tube that connects the kidney to the bladder, transporting urine produced in the kidneys to the bladder for storage. The urethra, on the other hand, is the duct through which urine is expelled from the bladder out of the body, thereby playing a key role in excretion.
Step 3
Maintenance ration and production ration
Answer
A maintenance ration refers to the amount of food required to maintain an animal’s body weight and health without facilitating any weight gain. In contrast, a production ration includes additional nutrients necessary for producing milk, meat, wool, or eggs, accounting for the extra energy and resources needed for these production activities.
