Recommended: Aspects of homeostasis

Firstly, what is homeostasis and what affect does it have on one’s overall health?. According to the Oxford Concise Medical Dictionary (PP356) homeostasis is, ‘The physiological process by which the internal systems of the body (e.g. blood pressure, body temperature, acid-base balance) are maintained at equilibrium, despite variations in the external conditions’ whilst also referring to Introduction to the Human Body (Tortora et al, PP6) describe homeostasis as the ‘maintenance of relative stable conditions… a condition in which the body’s internal environment remains steady despite changes inside and outside the body.’ ‘A state of dynamic equilibrium within the body’s internal environment; a balance achieved through the operation of various …show more content…

Negative thoughts will of course impact ones homeostatic state, in turn affecting ones overall wellbeing and health. The three are very much entwined and impinge on each other. Perfect homeostasis equals better health which in turn is better for one’s wellbeing. Homeostasis is also affected by other aspects such as ones digestive system, cardiovascular system or respiratory system which brings me to my next point, The circulatory and respiratory …show more content…

The circulatory system is made up of the heart, arteries, arterioles, capillaries, venules and veins. Arteries carry oxygenated blood (except the pulmonary or umbilical arteries) away from the heart whilst veins bring unoxygenated blood back to the heart. Capillaries are the thinnest of the blood vessels at only one cell thick, this is where blood diffuses from capillaries into venules and then veins. The heart is the giver of life. Without the heart and blood, the body is unable to function. As long as there is blood flowing through the body, the body strives to maintain homeostasis. For example, should one exercise, the body metabolises blood faster due to the need for oxygen around the body meaning the heart pumps faster to meet the demands of the body, in turn maintaining equilibrium and homeostasis. √
Blood is a vital tissue in sustaining life, health and wellbeing. Made up of various components its key task is to transport messages, deliver oxygen and other important minerals and gasses all over the body, whilst also acting as the body’s waste management service. The blood is made up of plasma (55%) and cells (45%) and makes up approximately 7% of one’s body weight Within plasma are both erythrocytes (red blood cells, RBC) and leukocytes (white blood cells, WBC) both of which are

Veins transport blood to the heart and lungs at low pressure after receiving it from the capillaries. Valves inside the veins keep blood moving in one direction. The human body's arterial system branches out from one main artery, the dorsal aorta. Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between.

The functions of the human cardiopulmonary system can be broken down into two, circulatory system and the respiratory system. The main goal of these two systems is to maintain homeostasis in our body. Homeostasis can be described as a type of condition where the internal continuity of an individual has to keep steadiness, regardless of any external changes from the outside environment. External changes from the outside environment may include factors such as excitement, stress, exercise, diet, and much more. Exercise can be carried out because the human body can endure a high level of exercise during a prolonged period of time.

Define homeostasis and explain its significance. - Ability to maintain relatively stable internal conditions even though the outside world changes continuously. Indicates dynamic state of equilibrium, or a balance, in which internal conditions vary, but always within relatively narrow limits. In general, the body is in homeostasis when its needs are adequately met and it is functioning smoothly. 8) Describe how negative and positive feedback maintain body homeostasis.

Mitral valve regurgitation is one of the few heart conditions you may unknowingly have for years and learn to live with the affects of this condition before ever being diagnosed. Mitral valve regurgitation occurs when the mitral valve is letting blood leak backward into the upper chambers of the heart. The mitral valve is located between your heart’s two left chambers . Mitral valve regurgitation, or mitral insufficiency as it is known, is a common heart valve disorder.

Homeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in and out of the body, while internal respiration is the chemical process that breaking down nutrients with oxygen to produce energy.

6 Fun facts about the circulatory system: If you stretch out all the arteries, veins, and capillaries; they will stretch out to 100,000 KM in distance, and this distance circles the Earth 2.5 times. The capillaries make up about 80% of the length, even though they are the smallest of all blood vessels. blood cells are roughly the same length and width as capillaries. Capillaries are 8 micros or 1/3000 inches big. However, some capillaries are smaller than blood cells, which forces these blood cells to change and distort shapes in order to go through these capillaries.

Other ways in which Catholics worshipped in the church of Saint Paul the Apostle was by stating a prayer over the many artworks featured on the walls and sculptures throughout the church. People would walk over to a statue or painting and kneel before it as a form of prayer and they worshipped those featured in the artworks, many of which were figures important to Christianity. They also worshipped through the many burning candles throughout the church. These candles are called votive candles, or prayer candles and they are usually white or beeswax yellow, and are burned as a votive offering as an act of prayer (Saunders). Candles are important to Christianity, and even Judaism, because their light was said to show the presence of God in a

The objective of this experiment is check how heart chambers, vessels and valves of the heart help the heart to achieve its function of pumping blood all over the body. In addition, this experiment would help us understand the double circulation of blood and reasons why it is vital for mammalian organisms. Due to the complexity of mammalian organisms, the exchanges of substances such as oxygen, nutrients and hormones cannot rely on diffusion itself (Kent, 2013). The transportation

BMR is the energy used to maintain metabolic homeostasis, muscle tone, circulation and breathing. Energy homeostasis is the balance between the food we eat (energy input) and energy we use (expenditure). Thyroid hormones influence metabolism so they influence energy expenditure. The hypothalamo-pituitary- thyroid (HPT) axis produces the T4 thyroxine) and T3 (tri-iodothyronine) hormones, and these stimulate energy expenditure via increased thermogenesis and because of this it has a key role in the regulation of energy homeostasis. The melanocortin system is important for energy balance and it controls both eating, energy intake and energy expenditure.

Holistic health thinks that health is maintained or reduced by the decision you make every day in all areas of your life and this could: emotional, mental, physical, or spiritual and these four functions help us go through the day and keep us going. Wellness is described as the accomplishment of success in these four areas or more. This is the reason why holistic health is not like allopathic health which focuses on the physical disease. Physical health under holistic approach looks at how a person’s response to disease, it is essential for individual to keep health by eating well, sleep well, having a good hygiene and considers if a person is active, they do not get unwell regularly, has physical strength and, they have a lot of energy.
