Flashcards in Systems of The Body Deck (11):
1

Integumentary 

involves?

functions? (5)

skin & associated structures - hair, fingernails, toenails, sweat & oil glands 

- protect body

- regulate body temp

- eliminate waste 

- make some vitamin D

- detect sensation - pain & touch, warmth, cold 

2

Skeletal 

involves?

functions? (5) 

Bones Joints, associated cartilages

- support

- protect

- provide surface area for muscle attachments

- house cells that produce blood cells 

- store minerals & lipids

3

Muscular 

functions? (4) 

skeletal muscle (muscle attached to bones) 

- participate in body movement

- walking

- maintain posture

- produce heat

4

Nervous

functions? (3)

Brain, Spinal cord, nerves, special sense organs (eyes ears) 

generate action potentials to regulate body activities 

- detect changes in internal & external environments 

- responds by causing muscular contractions or glandular secretions

5

Endocrine

function?

(def'n of hormone) 

hormone producing glands - pineal, hypothalamus, pituitary , thymus, thyroid, parathyroid, adrenal, pancreas, ovaries, testes

(italics means they are a gland) 

- regulate body activities by releasing hormones (chemical messengers transported in blood from endocrine gland or tissue to target gland) 

6

Cardiovascular 

functions? (3) 

blood, heart, blood vessels

- heart pumps blood through blood vessels 

- blood carries oxygen & nutrients to cells, carries waste & CO2 away 

- regulate acid-base balance, temperature & H2O content 

7

Lympathic 

functions? (3) 

lymphatic fluid & vessels, spleen, thymus, lymph nodes & tonsils, cells that carry out immune responses - B cells, T cells & others 

- returns proteins & fluid to body 

- carries lipids from GI tract to blood 

- contains site of maturation & proliferaton of B + T cells that protect against disease-causing microbes

8

Respiratory

functions? (3) 

lungs, air passageways: pharynx (throat), larynx (voice box), trachea (windpipe), bronchial tubes leading into/out of lungs 

- transfer Ofrom inhaled air to blood & COfrom blood to exhaled air 

- regulate acid-base balance of body fluids 

- air flowing out of lungs through vocal cords produces sounds 

9

Digestive 

functions? (3) 

organs of GI tract, long tube includes mouth, pharynx, esophagus (food tube), stomach, small & large intestine, anus, accessory organs that assist in digestive processes: salivary glands, liver, gallbladder, pancreas

- physicsal & chemical breakdown of food

- absorb nutrients

- eliminate solid waste 

10

Urinary 

functions? (3) 

- urine & wastes

- regulate?

- maintain?

kidney, ureters, urinary bladder, urethra

- produce/store/eliminate urine & wastes

- regulate volume + chemical composition of blood & production of RBC

- maintain acid-base balance & mineral balance 

11

Reproductive 

functions? 

- produce

- release 

Gonads (testes ovaries)

male: epididymides, ductus deferens, seminal vesicles, prostate, penis

female: uterine tubes, uterus, vagina, mammary glands

- gonads produce gametes (oocytes & sperm) that unite to form a new organism 

- gonads release hormons that regulate reproduction & other body processes

- associated organs transport & store gametes

- mammary glands produce milk
