Integrated Life Processes

Test how exchange, absorption, transport and kidney water handling depend on one another.

Interactive investigation

YOUR MISSION

Can nutrients reach body tissues when the transport pump is stopped?

Use a counterfactual to explain linked nutrient and oxygen delivery.
Distinguish excretion, egestion and selective reabsorption.

Before you begin

Describe a structure and its function. Change one variable at a time in a fair comparison.

Inspect the labelled model and its structure descriptions.
Record a prediction, choose the inputs and run a baseline.
Change one relevant input, predict again and run a comparison.
Compare the recorded outputs and explain a limit of this model.

EXPLORE IN THREE DIMENSIONS

Connected organ systems

Simplified educational model

Original sculpted organ contours, branching vessels and tissue sections. Gold highlights indicate a reached experiment checkpoint.

Anterior view: the person’s right is on your left. Rotate to inspect depth. Organs remain in approximate anatomical positions. Numbered labels match the structure list.

Model assumptions and limitations

Original procedural geometry approximates shape, position and relationships. It is not a scanned body, surgical atlas or calibrated physiology. Colours, separated layers and enlarged details aid learning. Anatomical variation is not represented. No personal health measurements are requested.

This is a spatial learning model. Colour, transparency and layer separation help reveal relationships; they are not measurements.

Your prediction What will change, and why? Name a condition you will hold constant.

Add a prediction of at least 8 characters.

Connect the observation to biology.

Digestion breaks food into absorbable substances; absorption differs from assimilation.

Ventilation, cellular respiration, circulation and excretion are connected but different processes.

Kidneys filter and selectively reabsorb; excretion removes metabolic wastes, unlike egestion.

How this model works

Nutrient delivery is the lesser of absorption and pumping. Oxygen delivery is the lesser of ventilation and pumping.
A fixed 100 water tokens entering the kidney split between reabsorption and excretion.

Independent comparison indices and water tokens, not organ function, blood pressure, urine volume or a medical model.

CONNECT THE IDEAS

What does the evidence tell you?

1. If pumping stops in this model, do high ventilation and absorption deliver materials to distant tissues?Yes; materials move there instantly.No; transport is also needed.Yes; kidneys make oxygen.

2. Which statement accurately describes this investigation?One successful run proves complete mastery.The model shows selected relationships and leaves other processes out.All displayed indices are real measured biological rates.

Build your investigation record.

Inspect two different structures
Record two trials with only one changed input
Explain the model through both conceptual checks
Save a conclusion of at least 12 characters

These markers record practice evidence. A written reflection is not automatically assessed, and one investigation does not establish mastery.

Prepared local guide

Class 10 · Integrated Life Processes. Digestion breaks food into absorbable substances; absorption differs from assimilation. Ventilation, cellular respiration, circulation and excretion are connected but different processes. Kidneys filter and selectively reabsorb; excretion removes metabolic wastes, unlike egestion. Before running: Can nutrients reach body tissues when the transport pump is stopped? Change one input while keeping the others fixed. What do you expect?
