organ systems and hormones

Question 1

what are the three systems that help metabolism?

Answer 1

mechanical system, factor exchange system, and circulatory system

Question 2

what is the mechanical system?

Answer 2

this system encloses and supports the human body and provides structures and framework for the body

Question 3

what are the two systems with in the mechanical system?

Answer 3

skeletal system (support the body, movement, and protection) and the integumentary system (forms the physical barrier between external and internal env.)

Question 4

what is the factor exchange system?

Answer 4

this system moves chemicals in and out of the body (connective tissue)

Question 5

what’re the systems within the factor exchange system?

Answer 5

respiratory system, digestive syst., and the urinary system

Question 6

what is the circulatory system? do verts have open or closed systems , how many?

Answer 6

link cells to the factor exchange system. verts have two closed systems

Question 7

what is the “liquid tissue” moved through vessels?

Answer 7

blood

Question 8

what’re the smallest vessels?

Answer 8

capillaries

Question 9

what’re capillaries ?

Answer 9

they are the gateway in and out of the circulatory system

Question 10

what’re the two systems within the circulatory system?

Answer 10

cardiovascular systm and the lymphatic system

Question 11

what is the primary system?

Answer 11

cardiovascular system

Question 12

what muscle is apart of the cardiovasc. system and what does it promote?

Answer 12

the heart and it promotes blood pressure

Question 13

what does BP do?

Answer 13

BP moves factors and forces fluids (like water) out of the system to bathe cells

Question 13

what is the name of the fluid that baths the cells?

Answer 13

interstitial fluid

Question 14

what’re components of the lymphatic system?

Answer 14

lymphatic vessels, lymphatic nodules, and lymphatic organs

Question 15

what’re the two functions of the lymphatic vessels?

Answer 15

pick up excess interstitial fluid and return it back to the cardiovasc. system as lymph. And collect lipids from the intestines and back to the cardiovasc. system

Answer 16

lymph

Question 17

what’re clusters of white blood cells?

Answer 17

lymphatic noduoles

Question 18

where are the lymphatic nodules abundant at?

Answer 18

mucosa lamina propria and in the lymphatic organs

Question 19

what are lymphatic organs and what is their function?

Answer 19

tonsils, protect the pharynx, lymph-nodes, protect the lymph, and the spleen this protects the blood supply (recycles red blood cells)

Question 20

what’re the two systems that govern metabolism?

Answer 20

the nervous system and the endocrine system

Question 21

what’re functions of the nervous system?

Answer 21

controls most body functions

Question 22

how does the nervous system control body functions?

Answer 22

by releasing neurotransmitters on target cells in synapses

Question 23

what allows cell to cell contact?

Answer 23

synapses

Question 24

what is the function of the endocrine?

Answer 24

secrete hormones for sustained control

Question 25

how does both the nervous system and endocrine system control metabolism?

Answer 25

by negative feed back

Question 26

what is the term for departure from a desired state is countered, resulting in homeostasis?

Answer 26

negative feedback

Question 27

what type of feedback loop can be pathological (cause disease/ death)

Answer 27

positive feedback loop

Question 28

what two things does the endocrine system consist of?

Answer 28

glands and hormones

Question 29

what is the gland referred to as the "master gland" ? what does it do?

Answer 29

the pituitary gland, and releases tropins, growth hormones , and vasopressin hormone

Question 30

what're tropins?

Answer 30

this is hormones to control other hormones

Question 31

what is vasopressin?

Answer 31

this hormone controls water levels in the blood and blood pressure

Question 32

Question 36

what gland releases epinephrine and cortisol?

Answer 36

the adrenal gland

Question 37

what does cortisol and epinephrine do for the body?

Answer 37

these hormones help get the body ready for physical effort. metabolism, blood to muscles and blood glucose is all increased

Question 38

what releases sex hormones? what is the function of these hormones?

Answer 38

the gonads, and these hormones cause sex differentiation and triggers reproductive readiness (puberty)
