Explain why humans are a system of systems. Provide at least one example in your explanation.

The human body is made up of several organ systems that work together as one unit. In the pyramid of life that organizes all of the elements of life into categories, organ systems are nested between an organism and its organs. Organ systems are the groups of organs that are within an organism.

Ten major organ systems of the human body are listed below along with the major organs or structures that are associated with each system. Each system depends on the others, either directly or indirectly, to keep the body functioning normally.

Explanation:

Circulatory System: The main function of the circulatory system is to transport nutrients and gasses to cells and tissues throughout the body

Digestive System: breaks down food polymers into smaller molecules to provide energy for the body.

Endocrine System regulates vital processes in the body including growth, homeostasis, metabolism, and sexual development. Endocrine organs secrete hormones to regulate body processes

Urinary Excretory System: removes wastes and maintains water balance in the body. Other aspects of its function include regulating electrolytes in body fluids and maintaining normal pH of the blood.

Skeletal System: supports and protects the body while giving it shape and form. The major structures include 206 bones, joints, ligaments, tendons, and cartilage.

Respiratory System: provides the body with oxygen via a gas exchange between air from the outside environment and gases in the blood.

Reproductive System: enables the production of offspring through sexual reproduction between a male and female.

Nervous System: monitors and coordinates internal organ function and responds to changes in the external environment.

Muscular System: enables movement through the contraction of muscles. Humans have three types of muscles: heart muscle, smooth muscle, and skeletal muscles.

Integumentary System: protects the internal structures of the body from damage, prevents dehydration, stores fat, and produces vitamins and hormones. The structures that support the integumentary system include skin, nails, hair, and sweat glands.
