biomed unit 2 study guide

skeletal structures

bones, skull, skeletal frame,

skeletal system functions

protects organs/muscles, allows for movement

muscular system functions

allows for movement, generates heat

urinary system structures

urethra, bladder, kidneys

urinary system functions

eliminates waste and fliters blood

lymphatic system structures

lymph nodes, lymphatic vessels, bone marrow

lymphatic system function

regulate fluids

integumentary system functions

provides a frame, regulates temperature, provides a boundauary

autopsy definition

a full examination of the body after death

two types of autopsies

forensic - used in a police investigation to figure out how they died
clinical - used in a medical investigation to further understand the body

cause, manner, and mechanism of death

cause - the injury that happened outside the body
mechanism - what happened inside in the body to result in death
manner - the nature and intent of the death

what happens during the microscopic examination

organs are removed and weighed, and

grossing definition

visually inspecting the organs/tissues and describing what is seen

steps of an autopsy

external then internal exam

celsius to fahrenheit equation

(Celsius times 9/5) + 32

forensic entomology

the study of insects on the bodies of forensic cases

define toxicology

the study of toxins and their effects of the body

order of food being digested

mouth, esophagus, stomach, small intestine, large intestine

functions of digestive system

break down food, absorb nutrients, create waste

metabolism definition

process of breaking down substances and converting them into energy

metabolites

small molecules produced as byproducts of metabolism

nervous tissue

found in nerves, spinal cord, and brain. the tissue sends, receives, and interprets signals

epithelial tissue

found lining outer surfaces of organs/blood vessels. absorbs, secretes, protects, and senses

muscle tissue

skeletal, cardiac, smooth. provides the ability for muscles to contract. found in the muscles

connective tissue

fat, bone, cartilage. connects tissue types, holds organs in place, attaches muscle to bones. found between tissue types

frontal lobe function

behavior, emotions, planning and organizing new information

TBI

brain dysfunction caused by an outside force to the head

CTE

a progressive deterioration of nerve cells caused by repeated head injuries

function of chordae tendineae

open/closes heart valves

function of papillary muscles

prevents leakage through the AV valves during systole

systemic circulation

through the heart and body

pulmonary circulation

through the heart and lungs

myocardial infarction is also known as

heart attack

what is a heart attack

when a blood clot blocks blood flow to the heart (coronary arteries)

atherosclerosis

a build up of plaque on the artery walls causing obstruction of blood flow

what happens during the external exam

height, weight, eye/hair color, external injuries, tatoos/markings, clothes and shoes

what happens during the internal exam

grossing, histology, brain, stomach contents, samples, toxicology

esophagus function

carries food from throat to stomach

small intestine function

absorbs nutrients and water

large intestine function

absorb remaining water and salt, get rid of waste
