Atrophy
Cell gets smaller
hypertrophy
Cell gets larger, due to adaptation
Hyperplasia
increased number of cells
Metaplasia
Change in the cell from onen typeof tissue to another,
this is adaptation and can be bad or good
Dysplasia
Abnormal adaptation
Like an extra finger or how cervical cancer froms
Reversible cell injury
Cell swelling
Intracellular accumulations
Necrosis
Irreversible cell injury or death
Different kinds of gang green
Dry, wet, Gas
Gas is usually caused by fungis
Apoptosis
Programmed cell death, very normal expecially on the surface of the skin and the intestianal track. This is also how our body avoids cancer.
Cell aging
Cellular basis of aging include, immune function decline, the thymis starts going bad at about 45 and we lose our Killer T cell production, which increases autoimmune disease
Physiologic changes / decreases (Cardiovascular)
decreased vessel elasticity
no of heart muscle fibers
filling capacity
sensitivity of baroreceptors , vein valves
Physiologic changes / decreases (Respiratory)
chest wall compliance
alveolar ventilation
respiratory muscle strength
Lung tissue
Physiologic changes / decreases (Gastrointestinal)
muscular contraction
esophageal emptying
bowel motility
Production of HCI, enzymes and intrinsic factors
Hepatic enzymes
Metabolizm
Stomach mucosa
Physiologic changes / decreases (Neruologic/ sensory)
Nerve cells
25% to 45% less of neurons
Neurotransmitters
Nerve impulse rate
taste buds
auditory hair cells
Physiologic changes / decreases (Musculoskeletal)
Muscle mass
Bone demineralization
Joint degeneration, erosion and calcification.
Physiologic changes / decreases (Immune)
T-cell function due to decrease in thymus gland
inflamation response
Physiologic changes / decreases (integumentary)
subcutaneous fat
elastin
atrophy of sweat glands
atrophy of epidermal arterioles causing altered temperature regulation
Somatic death
absence of respirations and heartbeat ... The death of an organism
18 common changes due to aging that are the result of physiological changes
Saggy and thin skin - Brittle toenails - Peripheral edema - Decreased body hair -Constantly cold - Fragile bones - Lack of diaphoresis - Decreased activity - Weight loss - Decreased appetite - Constipaiton - UTIs - Increased incontinence - Hypertension - Increased chronic illnesses - Increased acute illnesses- Arthritis - cough/lung congestion
Algor Mortis
Pupils dialate and body becomes pale, at this point the body begins to cool 1.5 degrees per hour until reaching poikilothermia (room tempreture)
Poikilothermia
Body is cold or at least the tempreture of environment
Liver Mortis
Gravity pulls all the blood toa dependant position usually within 4-6 hours
Rigor mortis
ATP stops production and stiffening sets in at about 6-24 hours
Post mortem autolysis,
body begins to bloat and begin aoutolysis, after 24 hours
Failure of the NA pump
will cause cell swelling and it can be reversed if problem is treated
When the Pancrease is injured what is released into the blood
Amylases
