• types of boneslong, flat, short, irregular
• types of jointsimmovable, slightly movable, freely movable

Choose an answer 1tendon function2 role & major organs/structures of immune system 3ligament function4description & location of cartilage Don't know?

description & location of cartilagetough but flexible covering at bone ends and joints to reduce friction; also shape and support at nose, ears, windpipe

• types of connective tissueligaments and tendons

ligament functionConnects BONE to bone tendon functionConnects MUSCLE to bone

• types of musclesmooth (organs), striated (movement), cardiac (combination only in heart)
• main divisions of nervous systemcentral (brain & spinal column) and peripheral (all others)

Respiratory System - key structures / organsUpper tract:

• Nasal Cavity
• Pharnyx (throat)
• Larnyx (voice box)

Lower tract:

• Trachea (windpipe)
• Primary Bronchi (bronchial tree)
• Lungs

respiration processoxygen IN => air > air passages > lungs > alveoli (air sacs in lungs) > capillaries > blood key structures of cardiovascular system1. Heart (4 chambers: 2 upper atrium, 2 lower ventricle; right side handles deoxygenated blood, left side handles oxygenated blood)

Blood vessels:

• Arteries/aorta (AWAY from heart)
• Veins/vena cava (TO heart)

pathway of blood through heart1. DE-OXYGENATED blood through veins FROM BODY into RIGHT ATRIUM (Superior Vena Cava from upper body; Inferior Vena Cava from lower body)

• Down through TRICUSPID VALVE into RIGHT VENTRICLE
• Up through PULMONIC VALVE and out PULMONARY ARTERIES to LUNGS
• Gas exchange in lungs = oxygen into blood
• OXYGENATED blood in FROM LUNGS down through PULMONARY VEINS into

LEFT VENTRICLE

• Up through MITRAL (aka bicuspid/left atrioventricular) VALVE into RIGHT

ATRIUM

• Out and away from heart through AORTA to Upper and Lower Body

major organs of digestive systemdigestive tract:

mouth > esophagus > stomach > small intestine > large intestine > colon

accessory organs:

salivary glands, liver, gallbladder, pancreas function of accessory glands of digestive system functions of accessory organs of digestive system 1. salivary glands in mouth (moisten, lubricate, begin digest carbs)

• liver (metabolizes macronutrients, creates bile, detoxifies)
• gallbladder (stores bile to digest & absorb fat)
• pancreas (secretes enzymes & hormones to help with digestion)

functions of digestive system1. ingest & digest food

• absorb nutrients
• eliminate waste

main organs of urinary (aka renal) system1. Kidneys - produces urine

• Ureter - carries urine to bladder
• Bladder - stores urine until need for elimination
• Urethra - tube allowing urine elimination from body (1-2 inch female; 8 inch

male) overall function of urinary systembalance fluids & salt through production of thirst balanced with urine production, storage, and elimination role & major organs/structures of immune system 1. role: internal protection from injury & infection

2. structure: lymph, lymph nodes, bone marrow, tonsils, adenoids, spleen, and

thymus gland (fluids, tissues, organs) structure & function of integumentary system1. function: external protection from injury & infection

2. structure: hair, skin, nails, and associated glands

functions of skin, hair, and nails1. skin: lubrication, protection, body temp regulation (through sweat production)

2. hair: insulation

3. nails: protect fingers and toes against soft tissue injury

role of endocrine systemachieve and maintain homeostasis through chemical messaging by hormones and enzymes location of male reproductive systeminside & outside pelvis function of male reproductive systemto produce & move spermatozoa (moving sperm)

organs of male reproductive system1. Testis or testicles (most men have 2)

• Scrotum
• Prostate
• Vas Deferens
• Urethra
• Penis

individual functions of organs in male reproductive system

1. Testis or testicles (most men have 2): produce sperm

2. Scrotum: house testis

• Prostate - house glands that help produce semen (aka fluid containing sperm)
• Vas Deferens (tube) - carries sperm from pelvic region toward urethra
• Urethra (tube) - excrete urine
• Penis (made of erectile tissue)- male sex organ

location of female reproductive systempelvic cavity and breasts function of female reproductive systemallow reproduction (encourage fertilization of eggs; support gestation); provide nourishment of offspring after birth; shed unused eggs when no fertilization occurs internal organs of female reproductive system1. vagina

• cervix
• uterus
• fallopian tubes
• ovaries

individual organ function of female reproductive system 1. vagina (bottom section leading to outer area),

• cervix (expands during birth),
• uterus (where fetus develops or sheds during menstruation if no ferilization),
• fallopian tubes (where egg fertilized),
• ovaries (where egg cells aka ova produced)

external organs of female reproductive systemExternal organs = Genitalia aka Vulva

• labia (lips surrounding vagina);
• vagina (collapsible tube connecting cervix and uterus to outside of body);
• urethra (small tube extends 1.5 inches into pelvis and is where urine exits body)
• clitoris - small erectile tissue similar to male penis in structure and function
