1. Explain the essence of homeostasis. Why is it crucial for the bodily systems to maintain homeostasis?

Homeostasis is the maintenance of a constant internal environment. Control systems throughout your body maintain automatic temperature & water at a steady pace, which requires cells to function. Rapid physical activity in hot or cold climates will affect homeostasis as well. It affects you temperature, hydration, blood oxygen levels, and salt levels. The temperature control system in an incubator, are similar to body control systems. Body systems have receptors to detect stimuli, processing centres to receive info and make responses and effectors which produce the response automatically. The overall importance of homeostasis, diffusion is the movement of molecules from a region of high concentration to a region of low concentration. Osmosis, is the overall movement of water from a solution through a partially permeable membrane. If excess water moves into …show more content…

What name is given to the condition of decreased thyroid hormone secretion? What related hormones are likely to decrease as well?

It can cause poor ability to take on the cold, a feeling of tiredness, depression, weight gain, and constipation. Thyroid hormone secretion decreases with age. Treatment with thyroid-releasing hormone is less effective in younger patients, while treatment with thyroid hormone is more effective in younger. Decreased responsiveness to injected releasing hormone may indicate a loss of hormone receptors in the anterior pituitary. Increased responsiveness to injected thyroid hormone may indicate up-regulation of hormone receptors, or it may indicate decreased metabolism of the circulating

Pathophysiology ANAT1066 Case study assessment Case study (b) INTRODUCTION Base on the clinical and laboratory data provided, the patient is suffering from Graves’ disease, a cause of hyperthyroidism which is a type of thyrotoxicosis. Clinical manifestation of Graves’ disease (GD) includes diffuse thyroid enlargement, palpitation and hyperthyroidism (Fukishima et al 2009). Other symptoms are ophthalmophathy which result in exopthalmos (bulging of the eye), and dermopathy (oedema) (mencori et al 2014). Hyperthyroidism has some symptoms such as heat intolerance, sweating and weight loss (mencori et al 2014). Tachycardia (a faster than normal heart rate at rest) and bruit (indicate hyper dynamic circulation) are among

The testosterone is a hormone that is responsible for stimulating development of male sexual characteristics. According to Clark Bartram, a man’s testosterone level reduces slightly as he ages. This gradual degradation leads to muscle loss, loss of sex drive, depression, erectile dysfunction and low energy. Low testosterone level in the body is becoming common daily.

Q1 The organs involved in the homeostatic system of salt regulation are pineal gland, pituitary glands, thyroid gland ,thymus, adrenal, pancreas, ovary and testis. All our bodies removes uneeded fluid by filtering your blood through your kidney, via osmosis, to draw excess water out of your blood. This requires a balance of sodium and potassium to pull the water across the wall from the bloodstream into a collecting channel in the kidney. A high salt diet will alter this sodium balance, causing the kidneys to have reduced function and remove less water resulting in higher blood pressure.

Unit 5 Anatomy and Physiology for Health and Social Care P4 Explain the physiology of two named body systems in relation to energy metabolism in the body The two body systems selected in relation to energy metabolism in the body are the digestive system and cardiovascular system. The digestive system breaks down foods and the cardiovascular system enables absorption and usage of the food. The term energy metabolism in the body relates to chemical reactions that that maintain cells and organisms. It is divided into two categories: catabolism is the breakdown of molecules to obtain energy and anabolism the synthesis of all compounds needed by the cells.

Maintain homeostasis of the body is more complex than it may seem at first glance, almost all organs play a role in the constancy of internal environment conditions. For example, keep a constant level of vital nutrients in blood and blood pressure should be monitored and constantly adjusted so that the blood to reach all tissues. At the same time the blood should not allow debris to accumulate in the tissues; this also should be involved in the regulation accurate body temperature. Basic control mechanism of homeostasis To maintain each of the numerous factors or variables that must be stabilized in the body there are basically three interdependent components in regulating

Sometimes men with hypopituitarism will experience erectile dysfunction and have a lack of body hair. Women may be infertile and stop menstruating. Children probably will stop growing prematurely, and lack sexual development. Finding this problem so that it can be treated is done by a lot of different blood testing to sort out hormonal problems that relate to the pituitary gland. Thyroid tests will pick up on any imbalances in thyroid hormones.

These hormones that are released have to do with growth of the body and brain and when there is little to no sleep, there is little to no growth (Eve Van Cauter). An example of one of these hormones is the adrenocorticotropic hormone which helps the body’s cortisol level, or stress level (Adrenocorticotropic hormone, 2013). When there is too little of the adrenocorticotropic hormone there is a high chance of poorly functioning adrenal glands or Addison’s disease which is when the body doesn’t produce enough hormones causing side effects of fatigue, loss of weight and muscle, and darkened areas on the skin (Adrenocorticotropic hormone, 2013). Effects of Sleep Loss When a person has a large sleep debt (the amount of rest that the brain is lacking) the brain starts to slow down, the immune system weakens, and the body can gain or lose weight along with many other health problems, mentally and physically (Sleep Deprivation).

Homeostasis is a very important property of organisms that occurs constantly in our bodies and is necessary to life. Homeostasis is defined as “the ability to maintain a constant internal environment in response to environmental changes.” To maintain homeostasis, the body goes through several steps. First, a stimulus causes a change in the body’s internal environment. The receptor senses the change and responds to the stimulus.
