What are the Function/Functions of the Cardiovascular System?
Circulates blood throughout the body and consists of the heart and blood vessels. Also responsible for moving nutrients throughout the body.
What are the Functions of the Endocrine System?
Collection of glands that secrete hormones. This produces and releases hormones.
what are the Functions of the Integumentary System?

what is the function of the urinary system?
produces, stores, and eliminates fluid wastes
what is the function of the digestive system?
breaks down food which includes the esophagus, stomach, and intestines
list the most basic cell forms to the most complex
cells, tissues, organs, organ systems, and organims.
what is thermoregulation?
to regulate the internal temperatures.
humans maintain an internal temp of what.
98.6 F
how do thermoreceptors detect a change in the body?
A nerve in the skin and brain that detect a change
what is positive feedback?
Positive feedback enhances or amplifies the stimulus.
what is negative feedback?
Negative feedback reduces or inhibits the stimulus.
do arteries go away from the heart or toward your heart?
the go away from the heart
Are the arteries oxygenated or deoxygenated?
there are oxygenated :)
Do veins go away from your heart or do they go toward your heart?
They go toward your heart
are veins oxygenated or deoxygenated?
there are deoxygenated [ p.s. good luck ]
what are the four types of tissue?
- connective tissue
- Epithelial tissue
- Muscle tissue
- Nervous tissue
what are the three types of muscle tissue?
- skeletal muscle
- smooth muscle
- cardiac muscle
Are Muscle tissues specialized cells
yes :0
where is each muscle cell located?
- The skeletal muscle is attached to the skeleton and is voluntary.
- The smooth muscle is in your organs and is involuntary.
- the cardiac muscle is in your heart and is involuntary.
what is Epithelial tissue?
this tissue serves as your barrier between your interior and exterior body.
what is Connective tissue?
this tissue supports protects, and gives structure to other tissues/organs in the body.
what is Nervous tissue?
This tissues main function is communication. this is also located in the brain, spinal cord, and the nerves.
Do all tissues perform the same function?
No. Because the muscle cells are specialized.
what is CER
CER stands for Claim Evidence and Reasoning.
how to write the Claim for CER
- one-sentence answer to the question investigated
- shouldn’t start with yes or no
how to write the Evidence for CER
- Use enough data to support the claim
- Use data that supports your claim. Leave out info that doesn’t support your claim
how to write the Reasoning for CER
- Ties together the claim and evidence
- how/why the data counts as evidence to support the claim
- explain why the experiment results occurred.
