Nervous system
The somatic nervous system controls?
You choose what it does
What does it mean to have specialized cells. Give an example
There are various kinds of cells and each one carries out an specific function
Ex.eye cells,muscle cell
Where are capillary beds found in the human body
Everywhere
Which blood has CO2 and which blood has O2
Blue blood-CO2
red blood-O2
What is the job of large intestines
It gets water back to your body
Autonomic nervous system controls?
This is when your brain your brain responds to certain stimuli
How many chromosomes does a human cell have
46 or 23 parts
What is the main purpose of a capillary bed
Diffusion
True or false is blue blood actually blue
FALSE blue blood it actually red
What are the 4 main tissues
1. Muscle tissue
2. Epithelial tissue(skin)
3. Nervous tissue
4.connective tissue(tendons+ligaments)
The CNS is made of 2 parts what are they
1.Brain
2.Spinal cord
Name the first 2 steps of cell division
Step 1. D.N.A gets capid and it gets wrapped up into the x shapes
Step 2. D.N.A gets pulled apart
What are the 3 parts inside the lungs called
Bronchi
Brencholes
Alveolies
Where does red blood travel
In the arteries
What is mechanical and chemical digestion
Mechanical-the physical break down of food(you chewing with your mouth)
Mechanical-the breakdown of large particles into smaller particles(your stomach)
An automatic response by the nervous system to an external stimulus without involving the brain is known as
Reflex response
Name the last 2 steps of cell division
Step 3. The cell goes under cleavags(split to 2)
Step 4. Two daughter cells(2 new cells)
How does a person breath in
(Steps 1 to 3)
Step 1. When you inhale your diaphragm contracts pulling your ribs up and out
Step 2. And this is lowering the internal pressure

Where does blue blood travel
In the veins
What is the pathway that a chunk of food takes through your digestive system
Mouth-esopagous-tummy-small intestine-large intestine-then out
What does CNS stand for
Central nervous system
What is cell division called
Body cells:mitosis
Single cell organisms:binary fission
What are steps on breathing out
(Steps 4 to 6 on breathing)
Step 1(4). When you exhale your diaphragm relaxes allowing your ribs to press on your lungs
Step 2(5). And that increased internal pressure
Step 3(6). Air comes out of body
Which blood foes away from heart and which blood goes to heart
Red blood-away from heart
Blue blood-to heart
