Monogastric

The video tutorial explores various digestive systems, starting with unicellular organisms that use phagocytosis. It then discusses the evolution from the gastrovascular cavity in cnidarians to the alimentary canal in nematodes. The tutorial covers the four types of vertebrate digestive systems: avian, monogastric, ruminant, and pseudoruminant. It focuses on the monogastric system found in mammals like humans and pigs, detailing the process of digestion and nutrient absorption.

What process do unicellular organisms use to ingest nutrients?

• Photosynthesis

• Phagocytosis

• Osmosis

• Fermentation

Which type of digestive tract is found in cnidarians like jellyfish?

• Alimentary canal

• Gastrovascular cavity

• Monogastric system

• Ruminant system

What is the primary function of the alimentary canal?

• To store food

• To transport nutrients

• To produce digestive enzymes

• To provide a one-way digestive tract

Which of the following is NOT a type of vertebrate digestive system?

• Avian

• Monogastric

• Bilateral

• Ruminant

What type of digestive system do humans have?

• Pseudoruminant

• Ruminant

• Monogastric

• Avian

In the monogastric digestive system, where does the mechanical breakdown of food begin?

• Mouth

• Esophagus

• Stomach

• Small intestine

What is the main function of the large intestine in the monogastric digestive system?

• Break down fats

• Absorb water

• Store bile

• Digest proteins
