Effects of exercise on excretory system and endocrine system

 

Effects of exercise on excretory system

Excretory system is the one that is responsible for excreting wastes from the body like urea, ammonia and excess salts. It is one of the crucial systems that provides a vital balance in the level of salts and fluids in the body. Hypothalamus regulates excretion by producing ADH (antidiuretic hormone) which acts to reduce the amount of water from the body hence reduce the rate of excretion. So, it is not unusual to have effects of exercise on excretory system. For example:

  • Exercise causes more water loss from the body which indicates the hypothalamus to release more ADH. That means ADH level also increases by exercise.
  • Production of more concentrated urine. Because of exercise, increased ADH conserves more water from the urinary tract hence concentrated urine is produced.
  • Decreases sodium (Na) level in the bloodstream
  • Exercise causes more sweat to keep the body temperature down
  • Provides fresh and healthy oxygenated blood supply to the major organs of excretory system
  • Removal of the toxic substances from the body through sweat

Regular light to moderate exercise benefits and boosts the functions of excretory system. It is very much related to the eating habits. People who want to be in a growth state need to maintain a positive nitrogen balance where nitrogen intake and output ration is 1. If excretion is greater than input, it creates a state of negative nitrogen balance I n the body and causes problems. An athlete with an eating disorder such as anorexia, nervosa may fall in negative nitrogen balance and negative net protein balance. Such individuals may develop diseases such as cancers, starvation due to famine and other conditions that result in negative nitrogen balance.

Effects of exercise on endocrine system

Endocrine system is also a crucial system that releases and maintains hormonal control which in turn helps in many physiological functions in the body. Exercise boosts hormone circulation, improves organ function, physical condition and improves the state of mind. So, exercise has effects on endocrine system too that might improve the overall condition. Such effects may include:

  • Increases testosterone production. Exercise stimulates the release of LH which triggers testosterone production.
  • Reduces body weight
  • Increases metabolic rate
  • Exercise increases insulin sensitivity by reducing blood concentration of insulin. And maintain glucose homeostasis.
  • Elevated blood flow. Exercise increases epinephrine levels which in turn increases the amount of blood that heart pumps.
  • Widening of blood vessels that allows the muscles to get more oxygen rich blood
  • Increases confidence
  • Increases libido
  • Reduces tension or anxiety. Exercise increases blood endorphin levels. Endorphins block the sensitivity to pain and reduce tension or anxiety by inducing a sense of euphoria.
  • Exercise reduces the risk of high blood glucose accumulation, shortness of breath, organ failure, circulation problems and many other problems associated with endocrine system.

So, effects of exercise on body systems (endocrine system) is very crucial.

Human cheek cell under microscope

Image
Introduction The linear tissue inside the mouth is known as the basal mucosa and is made up of squamous epithelial cells. These structures, commonly referred to as cheek cells, divide about every 24 hours and continuously leave the body. The following images are of the  cheek cell under microscope. The main parts of a cheek cell : cell membrane. Nuclear membrane cytoplasm. nucleus. organelle. These are the parts that will be visible to you if you put cheek cell under a microscope. You may often see  bacteria  also but that needs a better microscope. You will not see bacteria with a low cost microscope. Requirements for cheek cell slide preparation: The things that will be needed to prepare a slide for cheek cell are: Slide Cover slip Tooth pick Dropper Methylene blue dye Microscope Tissue paper (optional) How to prepare a wet mount cheek cell ? Take a clean microscopic slide. Take a dropper and put a drop of water on the central part of the slide. ( physiological saline can also be use

Vitamin A deficiency diseases and treatment

  Diseases and symptoms of vitamin A deficiency Vitamin A deficiency diseases are mentioned below: Liver cirrhosis Celiac disease Bile duct disorder Ratkana Xerophthalmia Beetroot stains Dry skin Itching Burning of the skin Disrupting physical growth Decreased fertility and infertility Deficiency and treatment About 350,000 preschool-age children go blind each year due to vitamin A deficiency, and most of them do not survive.  The most common clinical symptoms of vitamin A deficiency are night blindness and  xerophthalmia  .  Vitamin A deficiency in young children causes beetroot spots on the conjunctiva of the eye and various eye symptoms.  Inadequate intake of vitamin A can lead to protein-calorie malnutrition, lipid malabsorption and fever.  Among adults, breastfeeding mothers are most at risk.  Treatment: The recommended treatment for xerophthalmia in children 1 to 6 years of age is 210umol retinyl palmitate.  And this dose should be repeated one day later and then 2-4 weeks later.

5 best digital microscope for kids

Image
A Digital Microscope may be a variant of optical microscope that uses optics and a photographic camera to output a picture to a monitor, typically through software package running on a PC. A digital microscope usually has its own constitutional semiconductor diode source of illumination that is completely different from an optical magnifier therein there’s no ways to observe the sample directly through the lens system. The most distinction between a stereo magnifier and a digital magnifier is their magnification. With the assistance of a stereo microscope, magnification is decided by multiplying the lens system magnification by objective magnification. Since the digital microscope doesn’t have associate degree lens system, magnification can not be obtained by this methodology. Instead the magnification for a digital microscope was mostly determined by what number times larger samples were reproduced on a 15-inch monitor. though the scale of the monitor has modified, the physical size
