• The biological hierarchy of the human body is organized as follows: collections of cells form tissues, groups of tissues form organs, groups of organs create systems, and all organ systems together constitute an organism.
• A body system is defined as a collective of cells, tissues, organs, and anatomical structures that act together to perform a specific role in the human body.
• The human body is defined as the physical substance of the human organism, composed of living cells and extracellular materials organized into tissues, organs, and systems.
• The human body is organized into levels of increasing complexity, which include subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, and the biosphere.
• The research goal of Michael Levin's laboratory is to develop generative conceptual frameworks that help researchers detect, understand, predict, and communicate with diverse intelligences, including cells, tissues, organs, synthetic living constructs, robots, and software-based artificial intelligences.
• Chronic inflammation causes damage to healthy cells, organs, and tissues over time, potentially resulting in DNA breakdown, internal scarring, and tissue death.
• The cardiovascular system circulates blood throughout the body to deliver oxygen and nutrients to cells and tissues while removing waste products and carbon dioxide generated by metabolism.
• In the human body, collections of cells form tissues, groups of tissues form organs, and groups of organs create systems, which together constitute an organism.
• The human body is a single structure composed of billions of smaller structures categorized into four major kinds: cells, tissues, organs, and systems.
• Chronic inflammation, if left unaddressed, can damage healthy cells, tissues, and organs.
• Endocrine glands produce chemicals and release them into the blood to direct the functions of cells and tissues elsewhere in the body.
• Biological organization in the body follows a hierarchy where cells act as individual workers, tissues are groups of related cells, and organs consist of many tissues working together cooperatively to accomplish a larger job.
• A tissue is defined as an organization of many similar cells with varying amounts and kinds of nonliving, intercellular substance between them.
• In multicellular organisms, including humans, all cells, tissues, organs, and organ systems work together to maintain the life and health of the organism.
• A tissue is a group of many similar cells that work together to perform a specific function.
• Cortisol, the major glucocorticoid, regulates the production and use of glucose, fats, and amino acids by cells and tissues.
