Assignment: SCIE207 Phase 4 Lab Report Part 2
Title: Exploring Endocrine, Circulatory, and Respiratory Systems
Instructions: Your lab report from Part 1 along with the Part 2 activity will serve as a guide to answer the questions and to complete the tables for the endocrine, cardiovascular (circulatory), and respiratory systems.
When your lab report is complete, submit this document to your instructor in your assignment box.
1. Endocrine System
Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism?
Answer 1: Insulin and glucagon work together to keep glucose levels in the blood within the normal range. When there is an elevated blood glucose level, this stimulates beta cells in the pancreas to secrete insulin. The insulin facilitates the uptake of glucose by body cells, and the liver will uptake the glucose and stores it as glycogen. These actions return blood glucose levels back to normal. When there is decreased blood glucose, this stimulates the alpha cells in the pancreas to produce glucagon. The glucagon travels to the liver and facilitates the conversion of glycogen to glucose. This glucose is released in the bloodstream to return levels back to normal.
2. Cardiovascular System
Blood flows through the body in two distinct pathways: the pulmonary pathway and the systemic pathway. The blood flowing in the pulmonary pathway is deoxygenated, and it delivers this blood to the lungs to be oxygenated again. The blood flowing in the systemic pathway leaves the lungs full of oxygen and flows through the heart to be delivered to the body tissues.
Instructions: Complete the following table to demonstrate the correct order for the pulmonary and systemic circulation as you trace a drop of blood through the body.
Pulmonary Circulation
Systemic Circulation
1. Venules
1. Pulmonary veins
2. Veins
2. Left atrium
