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.
1. Endocrine System
Question 1: How does the insulin and glucagon secreted by the pancreas function in glucose metabolism?
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.

Question 2: How do the cardiovascular and respiratory system work together to deliver blood to the body tissues?
3. Respiratory System
Exercising is an activity that requires the actions of multiple body organ systems. Each system performs its specific tasks, but all of the systems must work together to allow effective total body function during exercising.
Using the lab activity, observe and record the physiologic changes that occur during exercising using the following chart:
|
Activity
|
Breathing Rate: bpm(breaths per minute)
|
Pulse Rate: bpm (beats per minute)

Question 3: The body experiences some stressor like exercise, fright, or emotional stress whether it is joy or sorrow. There are certain hormones like epinephrine and norepinephrine that are produced during these stressful events. These hormones are produced by the adrenal gland, and they will have an effect on the heart rate and breathing rate. Explain how the hormones produced by the adrenal could play a role in altering the respiratory and heart rates during exercise.
