Biology exam Endocrine system: Hormones: chemical messengers that coordinate the body’s activates. Substances secreted by cells that act to regulate the activity of other cells in the body. They are part of the endocrine system and they are slow acting but have a longer affect than neurotransmitters. Functions: * regulate growth‚ development‚ behavior‚ and reproduction. * Maintain homeostasis * Regulate metabolism and water and mineral balance * Respond to external stimuli

Why did the metabolic rates differ? Because of the different organs that were removed from the two other rats that would produce certain hormones 3. If an animal has been thyroidectomized‚ what hormone(s) would be missing from its blood? thyroxine 4. As a result of the missing hormone(s)‚ what would the overall effect on the body and metabolism be? Thyroxine wouldn’t be released which helps maintain metabolism and body. So 5. How could you treat a thyroidectomized animal so that it functioned

Review Sheet Results (1) 1. List the hematocrits for the healthy male (sample 1) and female (sample 2) living in Boston (at sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia. 1. The hematocrit value for the healthy male: 48 2. The hematocrit value for the healthy female: 44 Both values are normal because they are between the normal ranges: for males between 42-52% and for females between 42-47%. 2. Describe the difference between the hematocrits

The Endocrine System FOCUS: The endocrine system is one of the major regulatory systems in the body‚ along with the nervous system. However‚ the endocrine system responds more slowly‚ and has a longer-lasting‚ more general effect on the body than the nervous system. Endocrine tissues internally produce hormones which are released into the blood‚ where they are carried to target tissue and produce a response. Some hormones bind to receptors on the surface of the cell membrane‚ producing permeability
