the study of the functions of each structure |
|
Cell |
smallest unit of life |
|
Tissues |
groups of similar cells working together |
|
Organ |
two or more tissues working together |
|
Homeostasis |
maintenance of a stable, internal environment |
|
Describe the organization of an animal body from the simplest to the most complex levels |
1. chemical: atoms. molecules & bonding 2. cells: smallest unit of life 3. Tissues: group of similar cells working together 4. Organ: two or more tissues working together 5. Organ Systems: organ teams working together to preform vital body functions 6. Organism: a living individual
|
|
List the four main types of animal (human) tissues. |
Epithelial Connective Muscle Nervous |
|
Epithelial: Location, Function & Structure |
Location: covering the body lining & organ & body cavities (skin) Function: protective barrier Structure: cells tightly packed in one or more layers |
|
Connective: Location, Function & Structure |
Location: throughout body, most abundant tissue Function: binds tissues together & support organs Structure: widely scattered cells in a mixture of extracellular materials (matrix)
|
|
Connective |
CT=cells+protein fibers + ground substance |
|
Muscle: Location, Function & Structure |
Locations: depends on type Function: move body/parts or material through body Structure: long, cylindrical cells fairly close together |
|
Nervous: Location, Function & Structure |
Location: brain, spinal cord, nerves Function: conduct electrical messages Structure: large neurons(for conduction) & smaller (neuro) glial cells to aid the neurons |
|
11 Organ Systems |
1. Cardiovascular system 2. Respiratory system 3. Digestive system 4. Urinary system 5. Skeletal System 6. Muscular system 7. Integumentary system 8. Lymphatic system 9. Nervous system 10. Endocrine system 11. Reproductive system |
|
Cardi0vascular system function |
transport materials within the body |
|
Respiratory system function |
gas exchange of O2 and CO2 |
|
Digestive system function |
breaks down food & absorbs nutrients |
|
Urinary system fuction: |
removes liquid wastes |
|
Skeletal system function: |
supports body, anchors muscles & protects internal organs |
|
Muscular system function: |
movement |
|
Integumentary system function: |
protects body and temperature control |
|
Lymphatic and Immune system: |
defends body |
|
Nervous system function: |
controls body function |
|
Endocrine system function: |
regulates body through hormones |
|
Reproductive system function: |
produce gametes and offsprings |
|
Homeostasis |
Maintenance of stable, internal environment Importance: Survival depends on specific temperature & mixture of solutes |
|
What is set point? |
ideal value or range for optimal function |
|
5 Part Mechanism for performing homeostasis |
1. Stimulus 2. Receptor 3. Control Center 4. Effector 5. Response |
|
Body temperature - homeostatic mechanism |
1. Set point - Body temp near 37 2. Stimulus: body temp below set point 3. 4. Control center in brain activates warming 5. Response: 1)blood vessels constrict 2)person shivers 3) metabolic rate increase 6 Body temp rises |
