LAB QUIZ_ BIO_ENDOCRINE SYSTEM__(QUESTIONS AND ANSWERS)_ ALL 100% CORRECT AND EXAMINABLE||RATED 100%

Document Content and Description Below

PRE-LAB QUESTIONS 1. What is the function of the endocrine system? The function of the endocrine system is regulate metabolism, growth, tissue function, and sexual development. 2. Research two t... ypes of hormones and describe their mode of action. Two types of hormones are Aldosterone and Growth hormones. Aldosterone regulates salt and water balance. Growth hormones affects growth development; stimulates protein production. 3. Which gland is both endocrine and exocrine? The pancreas is both an endocrine and exocrine organ. 4. Which hormones control the “fight or flight” response? Hormones such as Epinephrine and Norepinephrine activate the sympathetic system (fight or flight response) and allows the body to increase heart rate. 5. What is Type 1 diabetes, and what is the treatment for this disease? Type 1 diabetes is a disease where patients are not able to produce insulin on their own and the treatment is that these particular patients must inject themselves or intake more insulin through a pump. 6. Describe how Ca2+ levels in the blood are regulated by hormones. The Endocrine System The Endocrine System Parathyroid hormones regulate blood calcium levels that is produced in parathyroid glands. When there is low calcium, the hormone is released, targeting the skeleton and intestines for calcium. 7. How do the nervous and endocrine systems work together to maintain homeostasis? The brain must recognize the issue and how much the body needs to fix it. The signals must be sent to the correct glance to release the exact number of hormones needed to help the body maintain homeostasis. EXPERIMENT 1: MICROSCOPIC ANATOMY OF THE ENDOCRINE SYSTEM Data Tables Table 2: Experiment 1 Image Observations Image Type Image Observations Thyroid Gland The thyroid gland is filled with thyroid follicles surrounded by cuboidal epithelial cells. Parathyroid Gland I observe small purple cells inside the parathyroid gland called chief cells. Pancreas I observed pancreatic islets within the pancreas and very small alpha and beta cells Adrenal Gland Within the adrenal gland I observed two sides containing the peripheral cortex with the medulla in between them. Pituitary Gland The pituitary gland has two lobes, the posterior pituitary and the anterior pituitary with the pars intermedia lying between them. Anterior Pituitary Gland I observed many cell clusters within the pituitary gland surrounded by the vascular canals. The Endocrine System The Endocrine System Post-Lab Questions 1.
