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:

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 ...view middle of the document...

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 |Pulse Rate: bpm (beats per |
| |minute) |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.

Postconditioning And Protection From Reperfusion Injury: Where Do We Stand? Position Paper From The Working Group Of Cellular Biology Of The Heart Of The European Society Of Cardiology

250 words - 1 page Abstract Ischaemic postconditioning (brief periods of ischaemia alternating with brief periods of reflow applied at the onset of reperfusion following sustained ischaemia) effectively reduces myocardial infarct size in all species tested so far, including humans. Ischaemic postconditioning is a simple and safe manoeuvre, but because reperfusion injury is initiated within minutes of reflow, postconditioning must be applied at the onset of
