A collection of tissues that performs a specific function is an ________. Log in. The organism level is the highest level of organization. In humans, as in all organisms, cells perform all functions of life. Each neuron is an elongated cell that consists of an axon, cyton, and dendron that is responsible for the transmission of nerve impulses. A disease may follow the structure of the human body. Cellular problems create issues at more complex levels of organization. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. The human body is organized from the lowest form of development, which is marked by conception, to the highest, which is characterized by the body's completed basic development just before birth. 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. 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. An, smallest independently functioning unit ofallorganisms; in animals, a cell contains cytoplasm, composed of fluid and organelles, functionally distinct structure composed of two or more types of tissues, group of organs that work together to carry out a particular function, living being that has a cellular structure and that can independently perform all physiologic functions necessary for life, group of similar or closely related cells that act together to perform a specific function. Group of organs that work together. What are the five different levels of the organisation?Ans: The cell, tissue, organ, organ system, and organisms are the five different levels of body organisation of living beings stating the body complexity of living organisms. Single celled organisms, like bacteria, are extremely small, independently-living organisms with a cellular structure. The eleven distinct organ systems in the human body covered in this book seen in Figure \(\PageIndex{2}\) and Figure \(\PageIndex{3}\) include: While only some functions and major organs of each system have been listed above, each of these organ systems will be covered in much greater detail in the following chapters of this book. 2.

A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. Figure 2. They only become active when they come into contact with a host cell. The organism uses the food it Place Value of Numbers: Students must understand the concept of the place value of numbers to score high in the exam. Organelles: Organelles are cellular fluid that is water-based and found together with functioning units. There are the following levels of structural organisation of living beings: i. Neural tissue allows electrical impulses to travel throughout the human body. The kidneys produce urine, which is moved to the bladder by the ureters. A group of organs that cooperate to carry out one or more functions is known as an organ system in biology. These functions can include cell membranes, mitochondria and ribosomes. Yes! As , EL NORTE is a melodrama divided into three acts. An organ is an anatomically distinct structure of the body composed of two or more tissue types. Chemical level - is the simplest level within the structural hierarchy. All of the previous building blocks come together to form systems that perform specific human functions. For example, a tumor can interrupt the function of the organ it is in, despite the fact that it is a molecular mutation with direct cellular implications. But they also secrete hormones, as does the endocrine system, therefore ovaries and testes function within both the endocrine and reproductive systems. Life processes of the human body are maintained at several levels of structural organization. In multicellular organisms, including humans, all cells, tissues, organs, and organ systems of the body work together to maintain the life and health of the organism, Energy, Maintenance, and Environmental Exchange, Human Development and the Continuity of Life, 3 - Structural Organization of the Human Body, Describe the structure of the human body in terms of six levels of organization, List the eleven organ systems of the human body and identify at least one organ and one major function of each.
