Module 07 - Homeostasis Review

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is a hypertonic solution?

Back

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

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes outside the cell than inside, causing water to move into the cell, which may lead to cell swelling or bursting.

Front

What is the role of gills in fish?

Back

Gills are the respiratory organs in fish that facilitate gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled.

Front

How do blood vessels respond to cold temperatures in mammals?

Back

In cold temperatures, blood vessels constrict to reduce blood flow to the skin, minimizing heat loss and helping to maintain body temperature.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the function of hormones in the body?

Back

Hormones are chemical messengers produced by the endocrine system that regulate various physiological processes, including growth, metabolism, and mood.

Front

What is the endocrine system?

Back

The endocrine system is a network of glands that produce and release hormones into the bloodstream to regulate bodily functions.

Front

What is the significance of glucose in the human body?

Back

Glucose is crucial for cellular respiration, providing energy for cellular activities and is a primary energy source for the brain.
