discuss the five essential components of pathophysiology - ANS-study of human physiologic dysfunction in disease (disruption of homeostasis and feedback loops) 1110 specific diseases have been identified 1. Etiology= causative mechanisms "why" 2. Epidemiology= risk factors and distribution in populations "patterns" incidence and prevalence of disease. Incidence: #of new cases in a given population within a given time. Prevalence: # of cases existing (both old and new) in a given time ...

primary intervention - ANSremoves risk factors, so diseases do not occur examples of primary interventions - ANSimmunizations, seat belts, helmets secondary interventions - ANSdetecting disease when still curable examples of secondary interventions - ANSpap smears, routine blood screens, chemotherapy tertiary interventions - ANSpreventing further deterioration or reducing complications of disease examples of tertiary interventions - ANSbeta blockers following MI, chemo, radi...

What are the properties of a eukaryotic cell - ANS• Well define nucleus. • cells are larger and have more extensive intracellular anatomy and organization than do prokaryotes. • cells bind with deoxyribonucleic acid (DNA) and are involved in the super coiling of DNA. • cells have several chromosomes, protein production or synthesis . it consists of three components: outer membrane called plasma membrane, a fluid filling called cytoplasm, and the intra cellular organs or organelles...

When myocardial cells are injured, the function of the Na-K membrane pump may be impaired. Which of the following may then result? cellular sodium will increase b. extracellular potassium will decrease c. cell volume will decrease d. all of the above - ANSA Mr. Forbes is being prepared for open heart surgery when he suffers a myocardial infarction in which a large part of his left ventricle has suffered lethal cell injury. Mr. Forbes' CPK-MB and LDH1, enzymes associated with myocardial...

Which component of the cell produces hydrogen peroxide (H2O2) by using oxygen to remove hydrogen atoms from specific substrates in an oxidative reaction? A) lysosomes B) peroxisomes C) ribosomes D) oxyhydrosomes - ANSAns: B- peroxisomes What is a consequence of plasma membrane damage to the mitochondria? A) enzymatic digestion halts deoxyribonucleic acid (DNA) synthese B) influx of calcium ions halts adenosine triphosphate (ATP) production C) edema from an influx in sodium causes ...

CAD Risk Factors: Non-modifiable - ANSage genetic disposition family history ethnic background gender CAD risk factors - ANSAge >55 male fam hx personal hx peripheral vasc/Cerebrovascular disease smoking lipid abnorm DM HTN obesity sedentary cocaine estrogen use dyslipidemia - high LDL, low HDL, high triglycerides what happens when LDL becomes oxidized - ANSbecomes oxidized when exposed to endothelial cells and smooth muscle cell then exposed to macrophages becomes ...

atrophy - ANSshrinking in cellular size; capable of making entire organ to shrink, but most common in skeletal muscle, the heart, secondary sex organs, and the brain; aging causes brain cells to atrophy, and endocrine dependent organs to become dependent hypertrophy - ANSincrease cellular size associated with an increased accumulation of protein in the cellular components and not with increase in cellular fluid; most prone are the heart and kidneys; triggers for hypertrophy- mechanical, ex....

B-lymphocytes - ANS..., Responsible for humoral immunity. B-Cells are exposed to an antigen. When they encounter an antigen they imprint the antigen. Every bacteria has an antigenic site or antigenic marker. Immune system will respond to marker. Types of immunity - ANS..., Natural active immunity,Natural passive immunity,Artificial active immunity,Artificial passive immunity Immunotope - ANS... Epitope - ANS..., An area of the antigen molecle that stimulates the production of, and c...

Describe the extrinsic activation in apoptosis - ANSExtracellular signaling binds to the receptors on the surface of the cell (TNF) which activates intracellular apoptotic enzymes Describe the intrinsic activation in apoptosis - ANSMitchondria activated Cytochrome-C Proteins trigger the intracellular apoptotic enzymes Triggered by the lack of ATP Describe the steps of apoptosis - ANS1. Nucleus condenses and DNA clumps 2. DNA is enzymatically digested into uniform segments and length ...

A certain disease is currently found in 1 of every 10 people in the country and 1,000 people contract the disease yearly. The population of the country is 4,500,000. Which of the following statements is correct? a. The prevalence of the disease is 10% and the incidence is .02%. b. The prevalence of the disease is .02% and the incidence is 10%. c. Neither is correct. d. There is insufficient data - ANSA In relation to disease development, the term "etiology" refers to which of the follo...
