Organ Systems

Question 1

Integumentary System

Answer 1

Forms the external body covering, and protects deeper tissues from injury; synthesizes vitamin D, and houses cutaneous (pain, pressure, etc.) receptors and sweat and oil glands

Question 2

Skeletal system

Answer 2

Protects and supports body organs & soft tissues, and provides a framework the muscles use to cause movement; bones store minerals, inorganic salts and produce blood cells

Question 3

Muscular system

Answer 3

Allows manipulation of the environment, locomotion, and facial expression; maintains posture, and produces heat

Question 4

Lymphatic system/Immunity

Answer 4

Picks up fluid leaked from blood vessels and returns it to blood; disposes of debris in the lymphatic stream; houses white blood cells (lymphocytes) involved in immunity; the immune response mounts the attack against foreign substances within the body

Question 5

Respiratory system

Answer 5

Keeps blood constantly supplied with oxygen and removes carbon dioxide; the gaseous exchanges occur through the walls of the air sacs of the lungs

Question 6

Digestive system

Answer 6

Breaks down food into absorbable units that enter the blood for distribution to body cells; indigestible food stuffs are eliminated as feces

Question 7

Nervous system

Answer 7

As the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands

Question 8

Endocrine system

Answer 8

Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells

Question 9

Cardiovascular system

Answer 9

Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc.; the hearts pumps blood

Question 10

Urinary system

Answer 10

Eliminates nitrogenous wastes from the body; regulates water, electrolyte, and acid-base balance of the blood

Question 11

Male Reproductive system

Answer 11

Overall function is production of offspring; testes produce sperm and male sex hormone, and male ducts and glands aid in delivery of sperm to the female reproductive tract

Question 12

Female Reproductive system

Answer 12

Overall function is production of offspring; ovaries produce eggs and female sex hormones; the remaining female structures serve as sites for fertilization and development of the fetus; mammy glands of female breasts produce milk to nourish the newborn

Question 13

what are the 5 main organs/components of the integumentary system?

Answer 13

the skin and various accessory organs, such as the hair, nails, sweat glands, and sebaceous glands

Question 14

what are the 4 main organs/components of the Nervous system?

Answer 14

the brain, spinal cord, nerves, and sense organs

Question 15

what are nerve impulses?

Answer 15

electrochemical signals that nerve cells use within the nervous system organs to communicate with each other and with muscles and glands

Question 16

a particular hormone affects only a particular group of cells, called its ____ ____

Answer 16

target cells

Question 17

a hormone alters the ______ of the target cells

Answer 17

metabolism

Question 18

compared to nerve impulses, hormonal effects occur over…

Answer 18

a relatively long time period

Question 19

what are the 10 main organs/components of the endocrine

Answer 19

the hypothalamus of the brain; the pituitary, thyroid, parathyroid, and adrenal glands; and the pancreas, ovaries, testes, pineal gland, and thymus

Question 20

what are the 5 main organs/components of the cardiovascular system?

Answer 20

the heart, arteries, veins, capillaries, and blood

Question 21

blood transports the following:

Answer 21

gases, nutrients, hormones, and wastes

Question 22

what are the 5 main organs/components of the lymphatic system?

Answer 22

lymphatic vessels, lymph fluid, lymph nodes, thymus, and spleen

Question 23

cells of the lymphatic system are called ____

Answer 23

lymphocytes

Question 24

Which cells defend the body against infections by removing disease-causing microorganisms and viruses from tissue fluid

Answer 24

lymphocytes

Question 25

what two substances are transported by the lymphatic system?

Answer 25

tissue fluid and certain fatty substances from digestive organs

Question 26

what are the 12 main organs/components of the digestive system?

Answer 26

the mouth, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancreas, small intestine, and large intestine

Question 27

what are the 6 main organs/components of the respiratory system?

Answer 27

nasal cavity, pharynx, larynx, trachea, bronchi, and lungs

Question 28

what are the 4 main organs/components of the urinary system?

Answer 28

kidneys, ureters, urinary bladder, and urethra

Question 29

the final product of the urinary system is ___

Answer 29

urine

Question 30

what are the 9 main organs/components of the male reproductive system?

Answer 30

scrotum, testes, epididymides, vasa deferentia, seminal vesicles, prostate gland, bulbourethral glands, penis, and urethra

Question 31

what are the 6 main organs/components of the female reproductive system?

Answer 31

ovaries, uterine tubes, uterus, vagina, clitoris, and vulva

Question 32

What are the primary functions of the female reproductive system?

Answer 32

to produce and maintain female sex cells (eggs cells and oocytes), to receive sperm cells and transport them and oocytes within the system; also supports the development of embryos and fetuses, and provides the passageway by which the fetus leaves the prenatal environment

Question 33

What are the primary functions of the male reproductive system?

Answer 33

to produce and maintain sperm cells (spermatozoa) and transfer sperm cells into female reproductive tract
