Geriatric Water Content and Metabolism

These flashcards cover key vocabulary and concepts related to bodily water content, fat types, cellular processes, pH, and homeostasis as discussed in the lecture.

Body fat percentage in geriatrics

Geriatric individuals tend to have a higher body fat percentage, resulting in less water content in their bodies.

Brown adipose

A type of fat found in newborns that is metabolically active and has a high blood vessel count, contributing to high water content.

White adipose

The type of fat predominant in adults, lacking the vascularization found in brown adipose tissue.

Cellular respiration

The process by which glucose and oxygen are converted into water and carbon dioxide, producing ATP.

Osmosis

The diffusion of water from areas of high water concentration to areas of low water concentration through a semi-permeable membrane.

Electrolytes

Ions such as sodium, potassium, chloride, calcium, bicarbonate, and phosphate that significantly influence osmotic balance.

pH scale

A measure of acidity or alkalinity ranging from 0 (acidic) to 14 (basic), with 7 being neutral.

Homeostasis

The maintenance of stable internal conditions in the body, such as pH, to ensure proper physiological function.

Enzymatic activity

Biochemical processes facilitated by enzymes, which can be influenced by factors like pH and temperature.

Food preservation and pickling

The process of adding vinegar to foods to acidify and preserve them by denaturing the enzymes of microorganisms.
