Homeostasis and Transport Study Guide

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation.

Front

What type of solution is a cell in if it is isotonic?

Back

An isotonic solution has equal concentrations of solutes inside and outside the cell, resulting in no net movement of water.

Front

What is passive transport?

Back

Passive transport is the movement of particles from high to low concentration without the use of energy.

Front

What is the role of the nervous system?

Back

The nervous system controls and coordinates all body activities through electric impulses/messages between the brain, spinal cord, and nerves.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What is active transport?

Back

Active transport is the movement of particles against their concentration gradient, requiring energy.

Front

Define hypertonic solution.

Back

A hypertonic solution has a higher concentration of solutes outside the cell, causing water to move out of the cell.

Front

What is feedback regulation in homeostasis?

Back

Feedback regulation is a process where the body responds to changes in the internal environment to maintain stability.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of particles from high to low concentration, while osmosis specifically refers to the movement of water across a semipermeable membrane.

Front

What is the function of the endocrine system?

Back

The endocrine system regulates body functions through hormones released into the bloodstream.
