25
Role of gall bladder
Holds bile produced in the liver until it is needed to digest fatty foods (in the duodenum in small intestine)
26
Interphase
The phase of the cell where most time is spent. Copies DNA here and sets up organelles
27
What is cancer
DNA dividing uncontrollably
28
What causes cancer
Smoking, diet, products, genetics, radiation, viruses
29

Things that cause cancer
30
Define stem cells
Cells of the body which can divide and become differentiated. They can take place of cancerous cells
31
How is the body organized from the smallest cell to an organism:
Cells --> tissues --> organs --> organ systems
32

Enters nose or mouth - pharynx - throat - trachea - bronchi - bronchioles --> lungs --> alveoli
33

40
Role of liver:
Makes bile for small intestine & proteins important for blood clotting.
41
Role of gall bladder
Holds bile produced in the liver until it is needed to digest fatty foods (in the duodenum in small intestine)
42
Role of pancreas
To regulate blood sugar and create enzymes or digestive juices for the small intestine
43
Role of circulatory system
Transports important substances like gas, red blood cells, and platelets
44
Types of cells found in our blood stream
Red and white
45
Blood vessels:
Are the pathway for blood moving away from the heart
46
Veins:
The pathway to the heart
47
Capillaries :
Transfer oxygen and other nutrients throughout the blood stream and body
48
Artery clues
- have thicker walls - blood under high pressure - blood moves all over the body
49
Veins clues:
-has valves (no back flow)
50
Pulmonary:
Heart to lung , lung to heart
51
Cardiac subsystem:
Removed waste blood
52
Systemic:
to heart , to all body cells , to heart
53
Typical heart rate is:
72 bbm
54
Things that change normal heart rate:
Stress (up), dehydration, exercise, relaxation (down)
55
Systolic blood pressure:
The amount of pressure in your arteries when your heart beats.
56
Diastolic blood pressure:
Your blood pressure when your heart muscle is in between beats
57
Organ system tissues:
Epithelial tissue, connective tissue, nervous tissue, muscular tissue
58
Epithelial tissue:
The Protective tissue
59
Connective tissue:
- To transport materials - holds things together - (tissue between bones, cartilage, and arteries)
60
Nervous system:
Transmits signals from the brain to other parts of the body
61
Muscular tissue:
-allows movement (eg: esophagus, stomach)
