Digestive System Quiz

What is the function of the reticulum in ruminant digestion?

• Absorption of nutrients

• Production of digestive enzymes

• Microbial digestion of feed

• Storage of ingested food

Describe the anatomy of the omasum.

• The omasum is a long organ that connects the esophagus to the abomasum.

• The omasum is a spherical organ in ruminants that is divided into many folds or leaves. These leaves are covered with papillae that help in the absorption of water and electrolytes from the ingesta. The omasum also plays a role in the grinding and breakdown of food particles before they enter the abomasum.

• The omasum is a glandular organ that secretes digestive enzymes.

• The omasum is a flat organ that helps in the absorption of oxygen from the ingesta.

What is the main role of the abomasum in digestion?

• The abomasum is responsible for breaking down carbohydrates

• The abomasum helps in the absorption of water and minerals

• The abomasum is not involved in digestion

• The main role of the abomasum in digestion is to break down proteins with the help of hydrochloric acid and enzymes.

Explain the function of the crop in avian digestion.

• The crop produces enzymes that break down food before it enters the stomach.

• The crop stores and moistens food before it enters the stomach.

• The crop absorbs nutrients from food before it enters the stomach.

• The crop grinds food into smaller pieces before it enters the stomach.

How is the gizzard structured in birds?

• The gizzard in birds is a muscular organ located between the stomach and the small intestine. It grinds food with the help of small stones or grit that the bird has swallowed.

• The gizzard in birds is located in the head and helps with vision

• Birds do not have a gizzard

• The gizzard in birds is a soft, spongy organ that absorbs nutrients from food

What is the purpose of the reticulum in ruminant digestion?

• The reticulum helps in the absorption of nutrients in ruminant digestion.

• The reticulum is involved in the production of enzymes for ruminant digestion.

• The reticulum is responsible for storing excess food in ruminant animals.

• The purpose of the reticulum is to facilitate microbial digestion in ruminant animals.

Discuss the anatomy of the omasum.

• The omasum is the first compartment of the ruminant stomach.

• The omasum is located in the small intestine.

• The omasum is responsible for the absorption of nutrients.

• The omasum is the third compartment of the ruminant stomach.

What are the functions of the abomasum in digestion?

• The abomasum functions as the small intestine in digestion.

• The abomasum functions as the liver in digestion.

• The abomasum functions as the esophagus in digestion.

• The abomasum functions as the true stomach in digestion.

Elaborate on the role of the crop in avian digestion.

• The crop is responsible for breaking down food into smaller particles.

• The crop stores and moistens food before it enters the stomach, and aids in the digestion of food through the presence of beneficial bacteria.

• The crop is where waste is stored before it is excreted.

• The crop is a vestigial organ that serves no purpose in avian digestion.

Describe the structure of the gizzard in birds.

• The gizzard in birds is a soft, spongy organ that absorbs nutrients from food.

• The gizzard in birds is a muscular organ located between the crop and the small intestine. Its walls are thick and muscular, and it contains small stones or grit that help to grind up food into smaller pieces for digestion.

• The gizzard in birds is a small, vestigial organ that serves no purpose.

• The gizzard in birds is a hollow, fluid-filled sac that stores excess food.
