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

Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

The endocrine system is a control system of ductless glands that secrete chemical "instant messengers" called hormones that circulate within the body via the bloodstream to affect distant cells within specific organs. Endocrine glands secrete their products immediately into the blood or interstitial fluid‚ without storage of the chemical. Hormones act as "messengers‚" and are carried by the bloodstream to different cells in the body‚ which interpret these messages and act on them. Typical endocrine

The endocrine system is one of our body systems that plays an important role in living. It comprises of many glands exerting hormones in maintaining the body’s internal environment also known as homeostasis. The endocrine system plays an important role in homeostasis because it maintains growth and development‚ maturation‚ reproduction‚ human behavior‚ metabolism‚ sexual function and controls functions of the tissues. It is partnered with the nervous system since the hypothalamus along with the pineal

Endocrine system The Endocrine system is very important to our body. This system regulates our mood‚ growth‚ metabolism‚ tissue development‚ sexual functions and reproductive process. It is a very complex system with many different hormones and glands. I am going to write about the pituitary gland and thyroid. The pituitary gland is very often considered to be the most important glad in the Endocrine system. The Thyroid produces thyroxine andtriiodothyronine. The Pituitary gland is no bigger
