It is formed from a process known as ossification, which can be intramembranous (within the connective tissue membranes) or endochondral (formation on a cartilage mold).
Skin Respiration: Helper Function in Amphibians What it is - biological definition Skin respiration is that which occurs through the skin of the animal. Many animals do not have specialized organs for gas exchange, so they occur through the skin. How Gas Exchange Occurs The animals with cutaneous respiration system have cells and or blood vessels in the skin, and through them occurs the capture of oxygen from the environment.

The action of the immune system The action of the immune system begins very early in the intrauterine phase.
Connective Tissue: Important Functions in the Human Body What It Is Connective tissue is one of four major types of body tissue (epithelial, connective, muscular, and nervous). This tissue is found in large quantity in the human body. Main features Connective tissue has fewer cells and matrix in larger volume.
Human Biology: the human being as the focus of studies What is Human Biology is an interdisciplinary area of study within the Natural Sciences that has the human being as its main object of study. Being a broad and interdisciplinary area, Human Biology relates to other areas of knowledge such as Nutrition, Anthropology, Human Anatomy and Medicine.
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. There are also accessory digestive organs: teeth, tongue, salivary glands, liver, gallbladder and pancreas.
Localization of the cerebellum in the human brain Introduction This part of the brain is located anteriorly to the medulla ablongata and is responsible for postural coordination during rest and activity. 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).
Actin: example of contractile protein Introduction (classification criteria) Proteins can be classified according to the functions they perform in the body. Carrier proteins These are the proteins that carry molecules in and out of cells. They are plasma membrane proteins.
Herbs: Very Useful in Cooking and Medicine Introduction Herbs are found in nature in a wide variety. With wide use, they are very useful in cooking, medicinal use and also in other fields. Main characteristics and applications Its green leaves are often used in cooking, but its roots, flowers, seeds, stems and some other parts are widely used by complementary medicine for its medicinal characteristics.
