Unit 1 PBS Flashcards
Death ultimately occurs bc…
organ failure - can result from age, disease, and/or trauma
Integumentary System
KS: Skin, Hair, Nails
Fxn: Forms body’s external covering; protects deeper tissue from injury; helps regulate body temperature
Skeletal System
KS: Bones, Joints
Fxn: Protects/ supports body organs. Provide framework that muscles can use to cause movement. Stores minerals
Muscular System
KS: Skeletal, cardiac, and smooth muscle
Fxn: moves body; maintains posture; produces heat.
Nervous System
KS: Brain, spinal cord, sensory receptors, nerves
Fxn: Responds to internal/ external changes by response, processes info.
Cardiovascular System
KS: Heart, blood vessels (veins, arteries, capillaries)
Fxn: Pump blood, transports O2, CO2, nutrients, and waste
Respiratory System
KS: Lungs, nasal cavity, trachea, bronchus
Fxn: Gas exchange with external environment; keep blood supplied with oxygen and removes carbon dioxide
Lymphatic and Immune System
KS: Lymph nodes, spleen, thymus, bone marrow

KS: kidney, bladder, ureter/ urethra
Fxn: Elims waste; regulates water balance of blood.
Endocrine System
KS: Adrenal gland, pituitary gland, ovary, testis
Fxn: hormones, growth, reproduction, and metabolism by body cells.
Muscular and Skeletal (Relationship)
Skeletal provides a framework for muscles to move the body
Autopsy (purpose)
To determine the cause of death
Two types of Autopsy
Forensic and Clinical
Forensic: part of an overall investigation
Clinical: more interested in the disease processes.
