Ch. 1 Organization + General Plan of the body Flashcards
1
Q
Anatomy
A
is the study of structure + shape of the body/body parts
the hardness/rigidness of bones
2
Q
Physiology
A
study of how the body/body parts function
the bones function is to protect
3
Q
Levels of Anatomy
(there are 2)
A
-
Gross anatomy- (large structures) easily observable w/t an unaided eye
2.** Microscopic anatomy**- (very small structures) viewed only with a microscope
4
Q
organ systems
theres 11
A
- Integumentary
- skeletal
- muscular
- nervous
- endocrine
- cardiovascular
- lymphatic
- respiratory
- digestive
- urinary
- reproductive
5
Q
reproductive system
A
Production of gametes (sperm + egg)
6
Q
urinary system
A
eliminates nitrogenous waste (produced by cells)
regulation of materials (such as water, electroltes=Na+,Cl-K+)
7
Q
Digestive system
A
- breaks down food
- eliminates indigestable material
- absorbs nutrients into blood
- large intestines absorb water into bloodstream*
8
Q
respiratory system
A
- keeps the blood supplied with oxygen
- removes carbon dioxide
9
Q
Lymphatic system
A
- returns fluids to blood system
- involved in immunity
10
Q
cardiovascular system
A
- transports materials via blood pumped by the heart
- “Materials”= oxygen, carbon dioxide, nutrients, waste products
all of the blood vessels measure together laid out in a line, they would measure more than 60,000 miles in length
11
Q
Endocrine system
A
- secretes regulatory hormones
- hormones= growth, reproduction, metabolism
12
Q
nervous system
A
- fast acting control system
- interprets sensory input
- activates muscles and glands
13
Q
muscular system
A
- provides movement
- maintains posture
- produces heat
14
Q
skeletal
A
- protects + supports body organs
- provides muscle attachment for movement
- site of blood cell formation
- stores minerals
15
Q
integumentary system
A
- protects us from the environment
- protects from dehydration
- provides sensory info
