ANATOMY

Detailed explanation-1: -Humans-and other complex multicellular organisms-have systems of organs that work together, carrying out processes that keep us alive. The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.

Detailed explanation-2: -Each organ performs one or more specific physiological functions. The human bladder, which is composed of smooth muscle tissue, transitional epithelial tissue, and several types of connective tissue serves the function of storing urine produced by the kidneys.

Detailed explanation-3: -An organ is a group of tissues that work together for the overall function of the organ, and an organ system is a group of organs that work together to perform a specific function. The human organism consists of eleven organ systems.

Detailed explanation-4: -Living tissue is made up of cells. There are many different types of cells, but all have the same basic structure. Tissues are layers of similar cells that perform a specific function. The different kinds of tissues group together to form organs.

Detailed explanation-5: -The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium. All of these 11 elements are essential elements.
