Unit 3- Basic Body Systems

The Body Systems- A group of cells, tissues and organs,

coordinated to maintain life


To help us observe the effects of medications on our residents,

we need to understand the effects of medications on the

body systems. Use the "Body System Guide" from the email

and be sure to review the Unit 3 curriculum. Also focus

on the diseases of the cardiovascular system and respiratory system,

as meds are often prescribed for these common conditions.


The body system study guide from the email attachment clarifies

all you need to know for the actual Unit 3 quiz

Body Systems overview

Cardiovascular- blood circulation

parts- Heart, blood, vessels-


vessels- transport channels:

arteries take blood away from the heart

veins bring blood back to the heart

capillaries are tiny connectors between arteries and veins


function- delivers oxygen, fluids and nutrients


abnormal function-

  • CHF- congestive heart failure- poor circulation, leading to swelling
  • HTN- hypertension
  • CAD- coronary artery disease
  • CVA- cerebral vascular accident/stroke


Respiratory- breathing

parts- lungs


function- breathing


abnormal function-

  • COPD
  • Asthma
  • pneumonia
  • Common cold
  • URI- upper respiratory infection

Digestion- breaks down food

parts- Stomach, esophagus, intestines


function- Nutrition- breaks down and transports food, removes waste


abnormal function-


Nausea,

vomiting

diarrhea


Dysphagia- difficulty swallowing


Integumentary- skin

parts-

  • Epidermis- external layer
  • Dermis- mid layer
  • Subcutaneous- inner layer


function- Protects the body from germs, insulates for hydration and

temperature/ thermoregulation


abnormal function-


  • Epidermis- Sunburn
  • Dermis- minor cut
  • Subcutaneous- deep wound


Nervous- electrical director

parts- Brain, spinal cord, nerves, neurons


function-Neurotransmission, communication, coordination


Abnormal function-


Seizure- abnormal brain cell activity

affecting muscle tone


Endocrine- chemical director

parts- Regulation glands produce insulin


function- to control blood sugar


abnormal function- Diabetes/ glycemia


  • Hypo- low
  • Hyper- high


Diabetes can be hereditary


Lymphatic- natural immunity

parts- Lymph nodes and vessels


function- immunity


abnormal function- lymphedema


Urinary- waste fluid regulator

Your residents may be incontinent of urine: insufficient control of urine or stool


parts- Kidneys, ureter, bladder, urethra


function- waste fluid regulation urinary incontinence


abnormal function- incontinence


Skeletal- structure

parts- 200 bones in the adult human


function- body structure, organ protection

abnormal function- fracture


Muscular- movement

parts-

  • Cardiac muscle- heart
  • Skeletal muscle-muscle to bone
  • Smooth muscle- lines hollow organs


function- movement


abnormal function-


  • Sprain- soft tissue/ skeletal muscle injury


Reproductive- birth control

Be sure you understand how to give birth control tablets correctly to protect

your client from possible pregnancy
