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

Question 2: How do the cardiovascular and respiratory system work together to deliver blood to the body tissues?

Answer 2: ________________________

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.

Answer 3: ________________________

Explanation / Answer

1.During digestion carbohydrates are broken down into glucose. glucose level increases. pancreas secretes insulin which tells cells to take glucose in their blood stream.Excess glucose is stored in form of glycogen .Glucose level decreases after sometime . Glucagon is produced by pancreas which tells the parts to release glycogen

2.

The purpose of your heart is to pump blood to the organs and tissues of your body that need the oxygen and nutrients it carries. Oxygen-rich blood is pumped out of the left side of your heart into the arteries to these tissues and organs.

Blood that has delivered its nutrients and oxygen and is in need of oxygen comes back to your heart in the veins and enters the right-hand side of the heart . This blood which is in need of oxygen (so-called deoxygenated blood) is sent to your lungs to pick up oxygen and get rid of carbon dioxide.

3.

The cardiovascular control center for the body is located in the ventro-lateral medulla. Here heart rate slows if activated by the cardio inhibitory center in the medulla or speeds up if activated by the cardio accelerator.From this site, the two channels of the autonomic nervous system originate the sympathetic and parasympathetic components. The sympathetic components increase heart rate by releasing the neural hormone catecholamines - epinephrine and norepinephrine. These hormones are cardio accelerators. Acceleration of the heart rate is called tachycardia.
