top and bottom, horizontal, cross sections

Question 22

Organ systems

Answer 22

group of organs classified as unit b/c function together (kidney, bladder - urinary)

Question 23

Intermediate

Answer 23

btw medial and lateral

Question 24

Sagittal plane

Answer 24

left and right

Question 25

Lateral

Answer 25

away from midline

Question 26

Positive Feedback w/ good and bad example

Answer 26

Enhances original effect of stimulus, takes us away from homeostasis. Bad: severe blood loss- blood pressure decrease - decreased blood supply to heart - heart pumps less - blood pressure decreases and loops. Good: Birth - increase oxytocin hormone - increase contractions - increase oxytocin and loops. Clotting: vessels damaged - platelets cling to injury site - releases chemicals that attracts more platelets - platelets cling to injury site and loop

Question 27

Organ

Answer 27

composed of 2 or more tissues to compose function

Question 28

Deep

Answer 28

internal

Question 29

Tissue

Answer 29

group of many similar cells developed from same part of embryo and have same function ( muscles nerve)

Question 30

Body studied in 6 levels:

Answer 30

Atoms & Molecules, chemicals, cells, tissue, organ, organ systems, organisms

Question 31

Organization

Answer 31

parts of the organism have specific relationship with each other, their parts interact to perform specific functions, living things are highly organized

Question 32

Homeostasis

Answer 32

equilibrium, disease disrupts homeostasis

Question 33

Essential to organisms/life

Answer 33

organization, metabolism, responsiveness, growth, development, reproduction

Question 34

Anatomical position

Answer 34

Facing forward, palms facing front

Question 35

Negative Feedback w/ example

Answer 35

Reduces original effect of stimulus to maintain homeostasis. Ex: blood sugar rises, message sent to control center, control center has pancreas release insulin, blood sugar stabilizes and insulin release stops
