LATEST UPDATE 2024/2025 100% (GRADE A+)
Describe how your body responds to an infection.
Ans>> T cells produce cytokines, which stimulate B cells. B cells produce antibodies.
Identify role of DNA changes in congenital abnormalities.
Ans>> Mutations in genes or chromosomal abnormalities
How does development disrupts congenital abnormalities?
Ans>> Alterations of DNA
Describes factors that disrupt homeostasis and how disruptions affect wellbeing.
Ans>> (ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias.
Explain RAAS
Ans>> Renin-angiotensin-aldosterone system
1
,1. Reduce blood flow causes kidneys to release renin
> produce angiotensin I > converts angiotensin I to angiotensin II > vasoconstriction > release
aldosterone > kidneys conserve sodium and water > Result less water lost in urine and blood
pressure maintained.
DKA
Ans>> increased anion gap, decreased HCO3
How do kidneys compensate for alkalosis
Ans>> retain H and excrete HCO3
Untreated acidosis leads to an increase in which electrolyte?
Ans>> Potassium
West Nile Virus
Ans>> Transmitted through the bite of an infected mosquito. Severe signs and symptoms; high
fever, headache and stiff neck
2
,Lyme disease

hemophilia is more common in
3
, Ans>> males
Prenatal exposure to alcohol includes
Ans>> ND-PAE, decreased brain function, FAS
Connective vs muscle tissue disorders
Ans>> Connective- RA, Scleroderma, Lupus
Muscle - MS, Muscular dystrophy, Myasthenia Gravia
Describe Lupus
Ans>> Inflammatory disorder characterized by joint pain and butterfly rash
Describe Myasthenia Gravis
Ans>> It is an autoimmune disorder where antibodies attack own Ach receptors. This causes
weakness of skeletal muscles over the course of the day, along with ptosis, double vision, and
difficulty swallowing.
