### Examples of calculus use in medicine?

I got a question,

I suspect doctors don't actually use any calculus in their daily work with people. BUT, it is used in medical research and analysis.

For example, calculus concepts are applied in studying how medicines act in the body. I found an article called Half-life and Steady State that talks about how the patient might be taking a medication and all the same time the body is clearing the previous doses... Eventually there comes a "steady state" where the amount of "the amount of drug going in is the same as the amount of drug getting taken out."

Or, from www.math.gatech.edu/~bourbaki/MapleProjects.html

we find that calculus is used to find out the rate of change of the surface area for a rapidly growing adolescent. This ties in with medicine in the fact that sometimes the drug dosage depends on the size of the individual, and the surface area is one way to measure the size of a person.

BIOLOGY and MEDICINE research abound with mathematical models, and calculus is an essential tool for analyzing those models. I personally have not studied these in-depth, but taking a peek in a Calculus for Biology and Medicine course syllabus from a certain community college we find that on that course the students;

Calculus is simply an indispesable tool for modern science.

"I am supposed to teach my calculus class one lesson.

That lesson has to be on something that can be applied

to whatever I am hoping to major in. I am planning on

studying pre-med to become a doctor. Could you tell

me how doctors apply math learned in calculus 1?"

QUOTE

Many drug effects occur primarily when the blood level of the drug is either going up or going down. When the drug reaches steady state, these effects can be either attenuated or completely absent. For those of you who are familiar with calculus, one way to understand this is that these effects only take place ifthere is a first derivative other than zero.

"This worksheet, provides a correlation between height, weight, and surface area

for humans as determined by the commonly used West Nomogram. Additionally, partial derivatives (and the chain-rule) are used to find the rate of change of the

surface area for a rapidly growing adolescent."

QUOTE1. Analyze allometric models.

3. Analyze models in population growth models.

4. Analyze models in population biology for interacting species.

5. Analyze models for respiration and control of respiration.

6. Analyze models for cardiac dynamics and control of heart rhythms.

7. Analyze models for neuron dynamics.

8. Analyze models in pharmacology.

9. Utilize a computer-algebra system in a model's analysis.
