Aorta Artery: The Most Important in the Human Body Introduction (Function) Unlike veins, which carry deoxygenated blood back to the heart, arteries carry oxygen-rich blood throughout the body. This is through the circulatory system. Knowing the Arteries (Main Features) Arteries are blood vessels that carry blood under high pressure, since it should reach all parts of the body carrying oxygen and nutrients to all cells.
Heart: the machine of the human body What is / and both sides The heart is an organ formed by striated cardiac muscles. It is divided into two sides: the left side (left atrium and left ventricle) and the right side (right atrium and right ventricle). Functioning and Functions From its left side, the heart pumps blood throughout the body, drawing and distributing substances such as carbon dioxide and oxygen.
Adrenal Glands: Production of Important Hormones What They Are and Localization The adrenals, also known as adrenals, are two endocrine glands in the human body. They are located above the kidneys. Members of the endocrine system, the adrenal glands are very important to the human body because they make hormones essential for their functioning.
Teeth: Important Function of Chewing Food Introduction (What they are) Teeth are organs of the human body of hard consistency, calcareous nature and white color. The teeth are located in the mouth and fixed in the jaws. The main function of the teeth is to chew the food. The teeth are classified according to position and function.
Digestive System: Functions of Extreme Importance to the Human Body Introduction The Digestive System consists of the mouth, pharynx, esophagus, stomach, intestines (large and small), rectum and anus.

Cerebellum Functions It is also responsible for reflexes and voluntary movements, it also acts on the muscular system being responsible for muscle tone.
Hemoglobins: Carrying Oxygen in the Blood What It Is Hemoglobin is a protein present in erythrocytes (erythrocytes), constituting approximately 35% of its weight. It is a pigment present in the blood responsible for transporting oxygen from the lungs to tissues throughout the body. Functions In addition to transporting oxygen, hemoglobin also participates in the process of transporting nutrients to all cells of the body, in which the blood carries nutrients and collects the substances secreted by the cells, then carries them out of the body. body.
Bones: Several Important Functions in the Human Body Introduction Bones, like the entire skeletal system, perform functions of the utmost importance to the functioning of the human body. Main functions of bones and skeletal system: - Body support; - Impact protection. Several bones protect important organs of the human body.
Platelets: Fundamental in the Coagulation Process What They Are Platelets, also known as thrombocytes, are anucleated cytoplasmic fragments present in the blood. Function - Platelets have the main function to participate in the process of blood clotting, ie the formation of clots.
Female Reproductive System: Reproductive Organs Introduction (Composition) The female reproductive system consists of the ovaries, fallopian tubes (fallopian tubes), uterus and vagina. Ovaries and Function Ovaries produce hormones, such as female sex hormones (estrogens and progesterone) and secondary oocytes (cells that become eggs, or eggs if fertilized).
