Anatomical terms, body systems & homeostasis WK1 L1 Flashcards
WHAT IS ANATOMY?
STRUCTURES, CELLS, TISSUES, WHAT WE CAN SEE WITH THE NAKED EYE, WHAT WE ARE MADE OF.
WHAT IS PHYSIOLOGY?
HOW DOES THE BODY WORK, HOW THE BODY MAINTAINS HOMEOSTASIS, THE STUDY OF THE BODY AND ITS SYSTEMS.
WHAT IS PATHOPHYSIOLOGY?
THE STUDY OF WHAT IS HAPPENING TO THE BODY WHEN THINGS ARE GOING WRONG/GO WRONG LIKE DISEASES.
WHAT ARE THE HUMAN STRUCTURES FROM SIMPLEST TO COMPLEX?
ATOMS - MOLECULES - CELLS - TISSUES - ORGANS - OARGAN SYSTEMS - LIVING ORGANISIM
WHAT ARE THE 11 BODY SYSTEMS?
SKELETAL - MUSCULAR - INGUMENTARY - RESPIRATORY - DIGESTIVE - REPORODUCTIVE - URINARY - NERVOUS - CARDIOVASCULAR - ENDOCRINE - IMMUNE
WHAT IS HOMEOSTASIS?
DYNAMIC STATE OF EQUILIBRIUM - RELATIVELY CONSTANT INTERNAL ENVIRONMENT STATE
WHAT ARE RECEPTORS?
SENSORS IN THE BODY THAT MONITOR THE BODYS ENVIRONMENT AND RESPOND ACCORDINGLY.
(HORMONES, NERVE ENDINGS, ORGANS, SKIN)
WHAT IS THE CONTROL CENTER?
THE CONTROL CENTER CONTROLS THE BODY BY SENDING SIGNALS TELLING IT WHAT TO DO TO KEEP HOMEOSTASIS.
(BRAIN, SPINAL CHORD)
WHAT ARE THE EFFECTORS?
PARTS OF THE BODY THAT RESPONDS TO THE REQUESTED STIMULUS FROM THE CONTROL CENTER.
(MUSCLES CONTRACTING TO MOVE A LEG WHEN THE CONTROL CENTER SIGNALS WALKING)
WHAT ARE THE 3 COMPONENTS OF A FEEDBACK LOOP?
RECEPTORS - CONTROL CENTER - EFFECTORS
WHAT IS NEGATIVE FEEDBACK LOOP:
WHEN THE BODY NEEDS SOMETHING TO CHANGE TO KEEP RELATIVELY CONSTANT HOMEOSTASIS.
(CHANGE SOMETHING NOW, FIX THIS ISSUE)
WHAT IS POSITIVE FEEDBACK LOOP?
WHEN THE BODY REQUESTS THINGS TO STAY THE SAME OR EXAGERATE THE CURRENT STATE.
(THINGS ARE GREAT KEEP GOING, I WANT MORE)
WHAT IS THE INGUMENTARY SYSTEM COMPOSED OF?
HAIR, SKIN, NAILS
ENCASES BODY, DETECTION OF STIMULI, TEMPERATURE REGULATION, VITAMIN D SYNTHESIS, CELL FLUID MAINTENACE
WHAT IS THE SKELETAL SYSTEM COMPOSED OF?
BONES, CARTILAGE, JOINTS,
STRUCTURE OF BODY GIVING FORM, ENCASES PROTECTS INTERNAL ORGANS
WHAT IS THE MUSCULAR SYSTEM COMPOSED OF?
MUSCLES, MUSCLE ATTACHMENTS, MUSCLE STRUCTURE
ATTACHES TO BONES TO CONTROL BODY MOVEMENT WITH FLEXION, EXTENSION, ADDUCTION, ABDUCTION
WHAT IS THE NERVOUS SYSTEM COMPOSED OF?
NERVE STRUCTURES, BRAIN, SPINAL CHORD
CONTROLS BODYS MOVEMENTS, THOUGHT, AUTOMATIC RESPONSES FROM CONTROL CENTRE
WHAT IS THE RESPIRATORY SYSTEM COMPOSED OF?
AIRWAYS, LUNGS
INTAKES AND ABSORBS OXYGEN FROM AIR TO LUNGS, CLEANS WASTE GASES
WHAT IS THE CARDIOVASCULAR SYSTEM COMPOSED OF?
ARTERIES, VEINS, CAPILLARIES, HEART
TRANSPORTS DELIVERY OF OXYGEN, NUTRIENTS TO CELLS, TRANSPORTS EXPORTATION CARBON DIOXIDE, WASTE
WHAT IS THE IMMUNE SYSTEM COMPOSED OF?
ANTIBODIES, WHITE BLOOD CELLS, BONE MARROW, SPLEEN, THYMUS, TONSILS, LYMPH NODES
(PROTECTS BODY FROM HARMFUL GERMS, BACTERIA)
WHAT IS THE DIGESTIVE SYSTEM COMPOSED OF?
STOMACH, SMALL INTESTINE, LARGE INTESTINE, ESOPHAGUS
BREAK DOWN OF FOOD INTO NUTRIENTS TO BE ABSORBED INTO BLOOD STREAM, EXCRETES WASTE FROM BOWELS
WHAT IS THE URINARY SYSTEM COMPOSED OF?
KIDNEYS, BLADDER, URETHRA, RENAL PELVIS, URETERS
EXCRECTION OF WASTE FROM BLOOD AND URINE
WHAT IS THE REPRODUCTIVE SYSTEM COMPOSED OF?
FEMALE: OVARIES, UTERUS, VAGINA, CERVIX, FALLOPIAN TUBES
MALE: PENIS, URETHRA, SCROTUM, TESTICLES, EPIDIDYMIS, PROSTATE, SEMINAL VESICLES
(CONTROLS THE CREATION OF OFFPSRING)
WHAT IS THE ENDOCRINE SYSTEM COMPOSED OF?
ADRENAL GLAND, THYROID GLAND, PITUITARY GLAND, PANCREAS, HYPOTHALAMPUS, TESTICLES, THYMUS,
(CONTROLS HORMONES IN BODY)
WHAT IS ANATOMICAL VARIATION?
VARIATIONS FROM THE NORMAL
EXTRA ORGANS/ ORGAN VARIATION
