Many of them are simple and can make a difference to preserving the environment today and in the future. Key Eco-Friendly Attitudes For Citizens (Ordinary People) - Sort waste (organic and recyclable) to facilitate the process of separate collection and recycling.

The human body is made up of various systems The Human Body Systems Muscular System - Formed by the muscles of the human body. - Main functions: acts on body support, movement and balance of body temperature. Nervous System - Composed of the brain, spinal cord and various nerves.
Genes: microscope image What is - definition Simply put, we can say that genome is the genetic code of the human being, that is, the set of human genes. In genetic material we can obtain all information for the development and functioning of the organism of the human being. This genetic code is present in each of the human cells.
Digestive System: Food Digestion and Nutrient Absorption Introduction (Digestion) It is through ingesting food that our body removes the nutrients needed to build new tissues and also maintains damaged tissues. Main Functions This process is only possible thanks to the digestive system, which is responsible for transforming the food we eat into molecules small enough to penetrate our cells.
Blood plasma (top) What it is Blood plasma is one of the components of blood. Excluding white blood cells, red blood cells and platelets, what remains is blood plasma. Plasma corresponds to approximately 55% of the composition of human blood. Functions Blood plasma performs very important functions in the human body.
Fish: Gill Breathing Introduction It is through the breathing process that animals are able to exchange gas with the environment. Through aerobic respiration, animals obtain oxygen and eliminate carbon dioxide in the external environment. TYPES OF BREATHING AND ITS MAIN FEATURES Pulmonary Breathing It is that which is performed by the lungs of animals.
Appendix: inflammation requires surgery for extraction What is Appendix The appendix is a vermiform tube that starts from the first part of the large intestine and is located in the lower right region of the abdomen. Function Humans and apes are the only living beings that have an appendix. It is not clear which function it performs.
Inspiration and Expiration: The Air In and Out of Our Lungs Introduction Human breathing occurs through the air in and out of the lungs. This process depends on the variation of the pressure in the pulmonary alveoli in relation to the atmospheric air pressure. The process of inhalation (inhalation of air) - The diaphragm muscle contracts and it lowers and contracts.
Red tide: increase of microalgae in the sea. What is red tide In the marine region where sunlight can penetrate, there are organisms that together are called plankton. Among these organisms are microscopic algae. The red tide phenomenon results from the explosive growth of some microalgae species.
Anatomy: Study of the Human Body What is Anatomy (definition) Anatomy is a science that studies the physical structure of living things. The internal and external organs, their interactions, functioning, location and disposition are the main aspects studied by Anatomy. Human Anatomy focuses on the study of the human body and is considered one of the basic sciences of medicine.
Joints of the hand Summary of joints in the human body Introduction (what it is and types of joints) The articular system is made up of joints, that is, a point of contact between bones. Throughout our body we have different types of joints: some that are quite strong and immobile (known as synarthrosis) and others that allow movements because they are flexible (anfiarthrosis and diarthrosis).
Pituitary gland: secretion of various hormones What they are Pituitary hormones are those synthesized and secreted by the pituitary gland (endocrine gland at the base of the brain), which is also known as the pituitary gland. Adenohypophysis hormones and their main functions: - Human growth hormone (hGH): Its main function is to stimulate muscles, liver, cartilage and other tissues in the human body to synthesize and secrete IGFs (growth factors).
Bones of the Human Skull: Protection for the Brain Introduction The brain is responsible for commanding the entire functioning of the organism through circuits involving thousands of neurons. And beyond all the physiology involved, the integrity of such a structure, guaranteed by a bone structure, is required.
Liver: Several Important Functions in the Body What It Is The liver is an organ that acts as an exocrine gland (releasing secretions) and an endocrine gland (releasing substances in the blood and lymphatic system). It is the largest gland in the human body. Functions The liver performs many important functions within our body, such as: storage and release of glucose, lipid metabolism, protein metabolism (conversion of ammonia to urea), synthesis of most plasma proteins, drug and hormone processing, destruction. of worn out blood cells and bacteria, emulsification of fat during the digestion process through bile secretion, etc.
GH: acts on human growth Introduction (what it is) GH (growth hormone) stimulates the epiphyseal disc and periosteum during the growth phase. It is produced until the age of twenty-one. After this age, its production drops dramatically. Knowing GH (Key Features) This hormone is also anabolic, stimulates lipolysis (weight loss) and acts restoratively within our bodies.
Pancreas: Important Function of Production of Hormones and Digestive Enzymes What It Is The pancreas is a gland that is part of the digestive and endocrine system of vertebrates. The pancreas produces pancreatic juice that acts on the digestive process because it has digestive enzymes. This gland is also responsible for the production of hormones such as insulin, somatostatin and glucagon.
Human Anatomy: several areas of study Introduction Due to the complexity of the human body, Human Anatomy is divided into several branches (areas) of study to better study the organs, systems, functioning and interactions with the environment. Although they are separate branches, there is a strong integration between them to generate the necessary knowledge.
Red Blood Cells: Red Blood Cells What are red blood cells, also known as erythrocytes, are red blood cells. The red blood cell is the largest element present in the blood. There are about 5 million red blood cells per cubic millimeter in the blood of a healthy adult man (about 4.5 million in women).
Epithelial tissue: important in the formation of some glands Epithelial tissue (epithelium) - which is also known as epithelium, epithelial tissue is one of four types of tissue in the human body. It is formed by juxtaposed cells (joined together). Key features Epithelial tissue has the following characteristics: lack of space between cells (juxtaposed cells), lack of vascularization and excellent cell renewal capacity.
Stem: support and transport of sap What it is (definition) Stem is a plant organ that is responsible for supporting the tree tops and transporting the elaborate and gross sap produced by the plants from the roots to the leaves. The stem has a cylindrical body and is formed by several layers of various types of tissues.
Strawberry: Examples of Pseudofruits What They Are (Definition) Pseudofruits, also known as false fruits, are juicy (rich in juice) plant structures that are not fruits because they do not originate from the plant's ovary. They develop from a plant tissue next to a flower. Main characteristics of pseudofruits: - They have a physical aspect similar to true fruits (because of this it is common for people to call these structures fruit).
