`P5 – (explain the effects of physical and psychological changes as they reach older age)

Physical changes

Cardiovascular system: The heart pumps the blood around the whole body in order to carry oxygen in which the individual will be able to breather. Older adults may develop narrow arteries and other blood vessels; this is because many fats have increased inside the body in which increases the cholesterol levels and so the walls of the arteries are being narrowed, this may gradually become blocked if not taken care of. This is known as “atherosclerosis”, it defines “athero” which conveys the fatty/unhealthy deposits, and “sclerosis” conveys the arteries becoming much hardened. This process may consequently end up in an increase of the blood pressure which puts the individual at risk of stroke; this is when the blood is unable to reach the brain and may cause a heart attack. The heart is used the hardest in this life stage as the arteries harden the heart needs to pump harder and faster to ensure that the individual is still alive, this however, is considered a big risk for the individual as the blood pressure may increase to such that the individual may have a heart attack. The coronary heart disease is caused by the fatty/unhealthy deposits causing a blockage in the arteries. If the coronary artery is partly blocked, the individual will become more breathless and also may face extreme chest pains, this suggests that the blood flow may have decreased ad so increases the risk of a heart attack. With increasing age the heart becomes more vulnerable to disease. Even in the absence of detectable disease, the heart undergoes deleterious changes with advancing age. 

Respiratory system: An individual may gradually become breathless as the blood may e pumped around the body efficiently. Many part of the body such as the chest muscles and the lungs may  reduce in which they may not work efficiently, this is because both the body and the individual is becoming weaker due to the less function of the blood supply. The capacity decreases with age. Emphysema is a disease in which develops when the lungs may deteriorate due to the air sacs (alveoli) being damaged. In this case it may cause the individual to become breathless in which they may find it difficult to breathe; also it increases the risk of a heart disease. This disease is caused mainly due to smoking as it damages the lung which also reduces the amount of oxygen an individual will receive. The Chronic obstructive pulmonary disease (COPD) is the name of the condition in after the disease of Emphysema. This disease causes a blockage to the breathing of the individual; in which there may be a build up of fluid in the body.

Nervous system: At this life stage of life, the individual would have lost many neurones from their body and also lost part of their memory. This is due to the reason that their mind is unable to work properly, also the individual would be unable to recognise and memorise things as their mind/brain would not be at a stable state. The motor neurone disease is a rare disorder which only occurs in older people, this disease causes the nerves to degenerate in which the nervous system gradually slows down. It results in the individual becoming much weaker and also loses muscle tissues such as the white blood cells; this makes it difficult for them to fight off any bacteria or illness. 

Degeneration of the sense organs: Aging is seen as a huge factor as the sense organs are very sensitive and so they are the first to be affected during the physical changes. At the age of 45years old, an individual’s sight lessens in which they would find it difficult to read and write, also they may need to have glasses in which may improve their visual sight.

As an individual gradually progressing from an adult to old age, the sight lessens more and so the individual may have serious problems regarding their vision. The individual may begin to see blurring and cloudy images in front of them and also may begin to not recognise their own family; also known as loss of memory. Hearing is also a sensitive sense organ and so it also is affected very easily during the aging process. At this life stage, many older people find it hard to hear many different sounds as to them it may be unrecognised or it may just be that they have high hearing. The nerve cells inside the ear may have been damaged and so the individual may result in hearing loss and also this would be a disadvantage to them due to them not being able to communicate with others.

Cognitive changes: These changes are done t an individual who, as they age, their behaviour, memory or mental abilities may change. This life stage shows that the individual will not be able to function their brain properly. Older people, feel that it takes them longer to do things and so they feel as if they are slowing down in a sense this is correct as older people tend to do activities much slower than people of a different life stage. The response/reaction time for the older people would increase as they would be much slower in responding to a particular activity. For example, driving a car may be dangerous as they would not be able to put down the brakes immediately, this will take them approximately 10-20seconds longer as they will need to time to understand the action in which they will perform.

Musculoskeletal: This results in the individual’s loss in mobility which may result in creaking joints, aching bones and stiff muscles. Due to aging, the bones and also the muscles may begin to shrink as they may be worn out and so this will may the individual feel as if they are useless. This is because they are unable to do certain things. The muscles may begin to become thinner as there may be a lack of exercise and also a lack of a healthy nervous/immune system.

Absorption of nutrients: This is when the muscle is being wasted due to the poor absorption ...
