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…

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
