Development Through The Life Stages Essay Example

With regards to respiration, weakened muscles due to aging can cause difficulty breathing despite oxygen being supplied during inhalation and carbon dioxide being exhaled.

As individuals age, their body undergoes changes that may result in decreased function of certain organs like the lungs and chest muscles. This could make them more vulnerable to emphysema due to reduced capacity, which is partly attributed to diminished blood supply. Additionally, the aging process naturally impacts the nervous system resulting in reduced nerve transmission speed and breakdown. Consequently, elderly people may experience weakened reflexes and face potential movement-related safety risks.

As people age, physical changes may occur in the nerves and brain tissue. The most observable signs of aging are usually found on the skin, which can become saggy with wrinkles and hair that has turned white or gray. As a person's largest organ, the skin has multiple functions such as protecting against environmental factors and regulating temperature through its various layers: epidermis (cells, pigment, proteins), middle layer (oil glands, nerves, blood vessels), dermis (provides nutrition to epidermis) and an innermost layer containing sweat glands,hair follicles,blood vessels,and fat. Aging can cause various changes in the skin; for example,the outermost layer becomes thinner while pigment cells decline resulting in pale and thinning skin.Age spots like liver spots may also appear. Each layer of the skin contains connective tissue made up of collagen fibers for support and elastic fibers for flexibility.However,the middle layer experiences a decrease in elasticity due to reduced connective tissue resulting in more fragile blood vessels which could lead to bruising or bleeding under the skin.Additionally,the fat layer reduces over time,resulting in less insulation/padding making one more vulnerable to injury

that could compromise body temperature regulation thus leading to hypothermia.As age increases, sweat glands produce less sweat, making it harder to regulate body temperature and increasing the risk of overheating or heat stroke.

The skeletal system, which is crucial for shaping and supporting the body, consists of two parts: the axial section (including the skull, ribs, sternum, and vertebrae) and the appendicular section (comprising the limbs, pelvis, hyoid bone, scapula, and spinal column). The bones within this system serve as storage for minerals whilst also providing protection to internal organs alongside joints, tendons, ligaments and teeth. However, aging can cause changes in the skeleton that weaken bones and increase fall risk – leading to an inactive lifestyle resulting in bone loss. Additionally women undergo hormonal changes that result in mineral and calcium loss from their bone tissue.

Cartilage is crucial for bone movement and connectivity in joints as it provides cushioning. There are different types of joints, including ball-and-socket, condylod, gliding, hinge, pivot, and saddle joints. Joint rigidity and decreased flexibility often occur with age due to a reduction in synovial fluid and thinner cartilage in the joints. Moreover, cartilage can shrink and stiffen from inactivity, thereby reducing joint mobility.

The human body consists of several organ systems that function collaboratively. Organs are made up of living tissue cells that have a fundamental structure. Tissues comprise layers of identical cells that support other tissues like blood vessels and internal organs while epithelial tissue forms the outermost layer of the body.

As people get older, their cells undergo alterations that can cause a loss of function and abnormal activity. The different types of muscles found in the skeleton, stomach, internal

organs, and heart wall assist with movement. Aging results in the buildup of pigments and fatty substances like lipids as well as waste products such as lipofuscin tissue. Connective tissue becomes stiff which can lead to inflexible organs, blood vessels, and airways. Changes in cell membranes may result in difficulty obtaining oxygen and nutrients. Hormonal changes also occur with age affecting cells throughout the body since hormones act as chemical messengers produced by glands or cells. These hormones have varying effects including mood regulation, hunger/cravings control, reproductive cycle management (puberty/childbirth/menopause), etc., and hormone levels change with aging thereby impacting certain blood levels while slowing down hormone breakdown.

Menopause, a natural process in women's aging, involves bodily changes that can occur before or after the cessation of menstruation. Estrogen, produced by the ovaries or ovary, regulates ovulation and menstruation. Menopause marks the end of a woman's reproductive phase when eggs are no longer released every month and menstruation stops. It typically occurs at age 40 or later but may happen sooner due to ovarian damage or surgery.

Healthy self-esteem is an individual's overall sense of self-worth. While temporary boosts in low self-esteem often come from compliments given by loved ones, true healthy self-esteem involves honest self-assessment, recognition of strengths and weaknesses, and acceptance of oneself as-is.

Self-esteem can vary over a lifetime, exhibiting growth or decline as one ages.
