Student SheetName:Date:Instructor’s Name:Assignment: SCIE207 Phase4Lab ReportPart 2Title: Exploring Endocrine, Circulatory,andRespiratory SystemsInstructions:Your lab reportfrom Part 1along with the Part 2 activity will serve as a guide to answer the questions andtocompletethe tables forthe endocrine, cardiovascular (circulatory), and respiratory systems.When your lab report is complete,submit this document to your instructor in your assignment box.EndocrineSystemQuestion 1:How does the insulin and glucagon secreted by the pancreas function in glucose metabolism?Answer1:Insulin and glucagon work synergistically to maintain the blood glucose levels within the normalrange. The elevated blood glucose level stimulates pancreatic beta cells to secrete insulin. Insulinfacilitates the glucose uptake by body cells, and the liver uptake the glucose and store it as glycogen. Above actions reinstigate the blood glucose levels back to normal. When the blood glucose levels are lower, the pancreatic alpha cells produce glucagon. The glucagon triggers the liver to facilitate the conversion of glycogen to glucose which return levels back to normal.CardiovascularSystemBlood 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:Completethe followingtable to demonstratethe correct order for the pulmonary and systemic circulation as you trace a drop of bloodthrough the body.Pulmonary CirculationSystemic Circulation1. Venules1. Pulmonary veins2. Veins2. Left atrium3. Vena cava3. Left ventricle4. Right atrium4. Aorta5. Right ventricle5. Arteries6. Pulmonary arteries6. Arterioles7. Lung7. CapillariesQuestion 2:How do the cardiovascular and respiratory system work together to deliver blood to the body tissues?Answer 2:Oxygen inhaled through the nasal cavity or the mouth travels to the alveoli in the lungs where oxygen is exchanged for carbon dioxide via capillary exchange. The respiratory system functionsin the exchange of gases with the outside environment. The oxygenated blood flows back to the heart from the lungs. It enters from the left side of the heart and oxygen delivery to all the body tissues is carried out via the aorta. In the body tissues again, oxygen is exchanged for carbon dioxide via capillary exchange. This deoxygenated blood flows back to the right side of the heartand then to the lung. In the capillaries that run across the alveoli, carbon dioxide is exchanged foroxygen that has recently been inhaled. The carbon dioxide will then be exhaled through the mouth and nasal cavity.
