The kidneys produce urine, which is moved to the bladder by the ureters. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Q. Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. These include the chemical, cellular, tissue, organ, organ system, and the organism level. (Image credit: that work together are grouped into organ systems. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. Biologists have estimated that there are between 3 million to 30 million species on the Earth. Brain B. What are the 8 levels of organization of the human body?

A. The female ovaries and the male testes are a part of which body system? humans. In multi-cellular organisms, including humans, all cells, tissues, organs, and organ systems of the body work together to maintain the life and health of the organism. A cell is the smallest independently functioning unit of a living organism. To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules. The female ovaries and the male testes are parts of the reproductive system. Chapter 1. It does not store any personal data. An organ is an anatomically distinct structure of the body composed of two or more tissue types. However, some organisms represent a single cell as the entire body, while some have a few or millions of cells that constitute the entire body of an organism. Cells are the basic units of structure and function in the human body, as they are in all living things.

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. Atoms are made up of subatomic particles such as the proton, electron and neutron. *The highest level of organization is the organism, the living human being. Body functions are the physiological or psychological functions of body systems. Molecules form organelles, the basic component of cells. A.
