Approximately 70% of an adult's bone mass is made of inorganic mineral salts, predominantly hydroxyapatite. The main nutrient needed to form the hydroxyapatite crystals found within bone is a dynamic combination of both calcium and phosphate, working together to provide the skeleton with its characteristic strength and rigidity.

An adult human's heart pumps roughly 2,000 gallons of blood every single day, powering the body's transportation network. This extensive and essential network is the circulatory system, the primary system that transports nutrients throughout the body to reach every cell, tissue, and organ. The efficiency of this biological highway is crucial for our survival, carrying everything from oxygen and glucose to hormones and immune cells.

Over 99% of the body's calcium is stored in the bones and teeth, playing a critical role in their structure and hardness. This essential mineral is the primary component of a crystal compound called hydroxyapatite, which is the key to bone rigidity.

Adipose tissue makes up 20–25% of the total body weight in healthy adults with a normal body mass index. When considering which of the following terms means containing fat, the answer from a medical and biological perspective is 'adipose.' This specialized connective tissue is far more complex than a simple storage depot, playing crucial roles in energy regulation, insulation, and endocrine signaling.

Adipose tissue, commonly known as body fat, is a highly specialized connective tissue that plays a vital role in our health beyond simple storage. While often viewed negatively, fat is a dynamic endocrine organ that stores energy, insulates the body, and secretes hormones to regulate metabolism. Understanding which tissue stores fat in our body is the first step toward appreciating its complex functions.

Over 99% of the body's total calcium supply is stored in the bones and teeth. This fact reveals that the most common mineral found in the human body is calcium, a powerhouse nutrient critical for much more than just skeletal strength.

Made primarily of strong, collagen-rich connective tissue, tendons act as the essential bridge between muscle and bone. The benefits of tendons are multifaceted, underpinning virtually every voluntary movement we make and contributing significantly to both our athletic prowess and overall physical health.

According to the National Institutes of Health, bones consist of about 60% inorganic minerals and 30% organic materials, meaning bones are not proteins. This common misconception stems from the fact that a significant portion of the bone's organic material is, in fact, a protein known as collagen.

Muscles are a fundamental tissue in the body, with protein making up approximately 20% of their mass. This protein isn't a single type, but rather a complex collection of different proteins that serve distinct and vital functions. Knowing what kind of protein is in muscles helps clarify their structure and how they facilitate movement and overall bodily function.

The human body contains adipose tissue in various locations, serving functions far beyond mere energy storage. This specialized connective tissue, commonly known as body fat, plays a critical and dynamic role in metabolic health, hormone regulation, and insulation. Understanding what is body fat tissue called is the first step toward appreciating its complex biological importance.
