Dmitriev's Explanatory Dictionary
An organism is a living body of a person, animal or living plant as a whole
a whole in which various organs and systems function in harmony
maintaining life.
ORGANISM
Violation of the functioning of one organ or one of their systems affects the activity of all other systems and the entire organism as a whole,
since the body is a single whole, and not a collection of individual parts.
1. Basic concepts 2. The human body as a single self-developing and self-regulating biological system 3.1. Musculoskeletal system 3.2. Cardiovascular system (circulatory system) 3.3. Breath. Respiratory system 3.4. Nervous system 4. Metabolism and energy - the basis of the life of the human body
The human body is a single, complex, self-regulating and self-developing system, in constant interaction with the environment, with the ability to self-learn, perceive, transmit and store information. The functional system of the body is a group of organs that ensures the coordinated flow of vital processes in them. The following systems of the human body are distinguished: cardiovascular, respiratory, musculoskeletal, digestive, endocrine, excretory, etc.
Homeostasis is the relative dynamic constancy of the internal environment of the body (body temperature 36–37 ° C; acid-base balance of blood pH = 7.4–7.35; osmotic pressure of blood 7.6–7.8 atm.; hemoglobin concentration in the blood 130 –160 g/l, etc. Resistance is the body’s ability to work in conditions of unfavorable changes in the internal environment. Adaptation is the body’s ability to adapt to changing environmental conditions.
Reflex is the body’s response to stimulation, both internal and external, carried out through the central nervous system. Reflexes are divided into conditioned and unconditioned. Hypoxia is oxygen starvation, which occurs when there is a lack of oxygen in the inhaled air or in the blood. Maximum oxygen consumption (MOC) is the greatest amount of oxygen that the body can consume per minute during extremely intense muscular work.
A cell is an elementary living system that ensures the structural and functional unity of tissues, reproduction, growth and transmission of hereditary properties of the organism. Tissue is a system of cells and non-cellular structures united by a common physiological function, structure and origin.
The spinal column consists of vertebrae and has five sections: cervical (7), thoracic (12), lumbar (5), sacral (5), coccygeal (4-5)
Erythrocytes are red blood cells, they are carriers of the red pigment - hemoglobin. Leukocytes are white blood cells. The main function is to protect the body from pathogens. Platelets are blood platelets whose main function is to ensure blood clotting.
The main functions of blood: Transport - delivers nutrients and oxygen to cells, removes breakdown products from the body during metabolism. Protective – protects the body from harmful substances and infections, due to the presence of a clotting mechanism (stopping bleeding). Heat exchange – participates in maintaining a constant body temperature.
Respiration is a complex of physiological processes that ensure the consumption of oxygen and the release of carbon dioxide by a living organism. The breathing process is usually divided into: external (pulmonary) internal (tissue) External breathing is carried out using a breathing apparatus consisting of airways.
Tidal volume is the volume of air passing through the lungs in one respiratory cycle (inhalation, exhalation). Vital capacity (VC) is the maximum volume of air that a person can exhale after a maximum inhalation. Respiratory rate is the number of respiratory cycles per minute. One cycle consists of inhalation, exhalation and a breathing pause.
Pulmonary ventilation is the volume of air that passes through the lungs per minute. Oxygen consumption is the amount of oxygen used by the body at rest or during exercise per minute. Maximum oxygen consumption (VO2) is the maximum amount of oxygen that the body can consume per minute during maximum muscular work.
The formation of a motor skill occurs in three phases: Generalization phase – expansion and intensification of the excitatory process, as a result of which additional muscle groups are included in the work. The concentration phase is a differentiated inhibition of excessive excitation and its concentration in the necessary areas of the brain. Automation phase - performing a movement automatically, without the participation of attention and thinking.
Metabolism is two interconnected opposite processes occurring simultaneously, resulting in the assimilation of substances coming from the environment and their biological transformation into potential energy (assimilation), and the second process associated with the constant breakdown of substances and the removal of decay products from the body (dissimilation ).

Organism 7th grade
Highlight the common characteristics of all living organisms that distinguish them from nonliving organisms. The main signs of living things Metabolism Nutrition Respiration Excretion Irritability Reproduction Growth and development Cellular structure
Levels of organization of living things Living nature on our planet is complexly organized. It is a single whole consisting of interconnected parts - cells, organisms, species, natural communities and ecosystems. A cell is the smallest unit of living things.
All living organisms are made up of cells. A cell can be a separate organism or part of a multicellular plant or animal organism. The cell is a structural and functional unit, as well as a unit of reproduction and development of all living organisms living on Earth. A cell is the smallest unit of living things.
The cells that make up a multicellular organism are specialized and are not able to exist independently. They form tissues. Tissue is a collection of cells and intercellular substance that are similar in origin, structure and functions. Plant tissues Animal tissues Integumentary Mechanical Conductive Basic (phtosynthesizing, storage) Educational Epithelial Muscular Connective (blood, adipose, bone, etc.) Nervous
Tissues form organs that perform a specific function in the body. Organs can be combined into organ systems. An organ is a part of a multicellular organism that has a certain structure and performs certain functions.
The coordinated interaction of cells, tissues and organs forms a complete organism, which has certain properties. The body is an integral, self-regulating system capable of independent existence.
An organism is a being that has all the properties of a living thing: Metabolism and energy transformation (nutrition, respiration, excretion) Irritability Movement Reproduction Growth and development Features of the chemical composition (98% - oxygen, carbon, hydrogen and nitrogen) Cellular structure
A collection of individuals that have a similar structure, lifestyle, are capable of interbreeding with the appearance of fertile offspring and inhabit a certain territory form a species. Each species has its own range - the territory within which its individuals are distributed.
Representatives of any species occupy a certain territory, often divided by geographic, climatic and other obstacles into separate groups - populations. A population is a collection of individuals of the same species that occupies a certain space for more or less a long time.
A community of plants, animals, fungi and microorganisms sharing a common habitat, i.e. living together and closely interacting with each other forms a biocenosis. Examples of biocenoses Pine forest Birch forest Swamp Feather grass steppe
The totality of all biocenoses currently living on Earth forms the biosphere. Biosphere - the shell of the Earth populated by living organisms
What conditions are necessary for the existence of an organism? Metabolism Energy conversion
The influence of organisms on their environment is called environment-forming activity.
The influence of plants on climate and water regime Forest giant (Peru) Photosynthesis is the main source of oxygen in the Earth’s atmosphere. Plants create conditions for the breathing of all living beings. The absorption and evaporation of water by land plants affects climate. By humidifying the air and delaying the movement of wind, plants create a special microclimate that softens the living conditions of many species.
If we imagine that photosynthesis on the planet will stop, all the oxygen in the atmosphere will be used up in just 2000 years. Tropical forest - the “green lungs” of the planet Velvichia
Soil-forming activity of living organisms The joint activity of many organisms creates soil. Each lump of soil contains millions of cells of various microorganisms.
The influence of aquatic organisms on the quality of natural waters. Filtration feeding is observed in 40 thousand species of aquatic animals. As a result of this activity, biological self-purification of water bodies occurs.
The biosphere is the shell of the Earth populated by living organisms. The biosphere includes three shells: Atmosphere Hydrosphere Lithosphere
Draw a conclusion on the lesson problem. Biologists view living nature as a collection of biological systems at different levels of organization. Moreover, some biological systems are elements of others that belong to a higher structural level of organization of living matter. They study the diversity of living organisms at various levels of organization and various systematic units. How do biologists study the diversity of living organisms?
