Answering Post Lab Questions for Frog Dissection
After completing a frog dissection in the lab, it is important to answer post lab questions to assess the knowledge gained and reinforce the learning experience. These questions typically cover topics such as the anatomy and functions of different organs and systems in the frog’s body.
Question 1: What is the purpose of the frog’s liver?
The frog’s liver serves several important functions. It produces bile, which is necessary for the digestion and absorption of fats. The liver also detoxifies harmful substances and stores vitamins and minerals.
Question 2: Describe the pathway of food through the frog’s digestive system.
Food enters the frog’s mouth and travels down the esophagus to the stomach, where it is broken down by acid and digestive enzymes. From there, it moves into the small intestine, where nutrients are absorbed into the bloodstream. Any undigested waste then passes into the large intestine and is eliminated through the cloaca.
Question 3: What is the role of the frog’s respiratory system?
The frog’s respiratory system allows it to take in oxygen from the surrounding environment and release carbon dioxide as a waste product. This is accomplished through the lungs, which are highly vascularized to facilitate gas exchange.
Question 4: What is the function of the frog’s urinary system?
The frog’s urinary system, consisting of the kidneys, ureters, bladder, and cloaca, is responsible for filtering waste products from the blood and maintaining water balance in the body. The kidneys filter waste and excess water from the bloodstream, which is then excreted as urine through the ureters and stored in the bladder before being eliminated through the cloaca.
Answering post lab questions helps students consolidate their understanding of the frog’s anatomy and physiology. It allows for reflection on the dissection experience and encourages critical thinking about the structure and function of the frog’s various organ systems.
