A process used to produce copies of specific DNA sequences from a small amount of DNA
Autopsy
Performed to determine the manner and cause of death
Systems
Groups that work together to perform a specific function’s
Respiratory system
Function: assist with gas exchange with the extra no environment keeps blood supplied with oxygen and removes carbon dioxide
Key structures
Lungs nasal cavity trachea and bronchus
Lymphatic system
Filters fluid in the body mounts the attack against foreign substances in the body
Lymph nodes spleen thymus bone marrow
Integumentary system
Forms the bodies external covering protect a deeper tissue from injury helps regulate body temperature
Skin hair nails
Urinary system
Eliminates waste from the body regulates water balance of the blood
Kidney Blatter ureter urethra
Cardiovascular system
Pumps blood around the body transports oxygen carbon dioxide nutrients and waste
Heart blood vessels veins arteries and capillaries
Digestive system
Breaks down food into its nutrients molecules absorbs nutrients rid of the body of waste
Oral cavity esophagus stomach small intestine and large intestine and liver
Skeletal system
Protects and supports the body organs provides a framework the muscles can use to cause movement stores minerals
Bones and joints
Muscular system
Move the body and move substances around the body maintains posture and produces heat
Skeletal muscle cardiac muscle smooth muscle
Endocrine system
Secretes hormones that regulate processes such as growth reproduction and metabolism by body cells
Adrenal gland pituitary gland ovaries testes
Nervous system
Response to internal and extra no changes by activating an appropriate response processes information
Brain spinal cord sensory receptors nerves
