Blood and its components

 Blood and its components

 Blood is a fluid that flows throughout the body within blood vessels. The Blood is essential for life, because it transports oxygen and nutrients to the organs and tissues, and helps eliminate waste. Additionally, blood helps fight infections and heal from injuries. In this sheet you will find more information about blood and its important function in the body.

What are the blood's components?

 Blood consists of different parts or components, which are: red blood cells, blood cells whites, platelets and plasma.

 Red blood cells (also called “erythrocytes” or “red blood cells”) are cells that They transport oxygen throughout the body. Each red blood cell lives for approximately four months. Red blood cells contain a protein called hemoglobin, which It allows oxygen to be collected from the lungs. The body needs iron to produce hemoglobin.

 White blood cells (also called “leukocytes”) are cells that are part of the body's immune system, and help fight infections and diseases.

 There are different types of white blood cells: neutrophils, lymphocytes, monocytes, eosinophils and basophils. Depending on the type of cell, white blood cells live for several days, months or years.

 Platelets (also called “thrombocytes”) are cells that help blood clot. blood. After a cut or bruise, platelets stick together to form a clot or “plug” that helps control bleeding, preventing the body from losing Too much blood. Platelets live in the body for 7 to 10 days.

 Plasma is the liquid part of blood. This liquid transports the different types of blood cells to all parts of the body; In addition, the plasma transports some proteins called “clotting factors” that help platelets form clots.

 Where in the body is blood produced?

 Blood cells are produced in the bone marrow, which is the soft and spongy inside the bones. New cells are produced every day blood cells to replace those that die naturally or due to an injury or disease.

Plasma is mostly made up of water. Furthermore, plasma contains various proteins, fatty substances, salt, nutrients, vitamins and hormones.

Human Liver

 Human Liver The liver is an organ that is present in both humans and other vertebrate animals. The human liver has an average weight of 1500 g,[1]​ it is located in the upper right part of the abdomen, below the diaphragm, it secretes bile, essential for the digestion of fats, it also has many other functions,[2 ]​ among them the synthesis of plasma proteins, storage of vitamins and glycogen and detoxifying function. Its main cells are hepatocytes and one of its most characteristic features is that it has the ability to regenerate. The liver is responsible for eliminating different substances from the blood that may be harmful to the body, including alcohol, converting them into harmless ones. The absence of a liver or its lack of functioning is incompatible with life. Etymology  The word "liver" does not derive from its Latin homonym jecur, nor from the Greek hepatos. It comes from the Latin expression ficatum jecur which literally means “liver fattened with fi...

Human Stomach

 Human Stomach  The stomach (from the Latin stomăchus, derived from the Greek στόμαχος [stomachos], from the prefix στόμα [stoma], "mouth") is the portion of the digestive tract located between the esophagus and the intestine. In humans, it is located in the upper left region of the abdomen, below the diaphragm. It is a chamber in which the ingested food is mixed and stored and is emptied in small intervals towards the duodenum thanks to peristaltic movements. Complete gastric emptying requires several hours after a large meal. The stomach is very distensible, so it varies considerably in size depending on whether it is full or empty. It is divided into four main regions, which are called: cardia, which joins it to the esophagus, fundus, body, and pylorus, which connects it to the intestine. It secretes several substances that are collectively called gastric juice, formed mainly by hydrochloric acid and pepsin, a proteolytic enzyme that divides proteins into smaller frag...

Respiratory System

Respiratory system   Definition   "The respiratory system allows oxygen to enter the body, as well as carbon dioxide to escape." Mechanism   To stay alive, the body needs to produce enough energy. This energy is produced by the combustion of nutrient molecules, which are oxidized when they combine with oxygen. Oxidation involves the combination of carbon and hydrogen with oxygen to form carbon dioxide and water. The consumption of oxygen and the production of carbon dioxide is an essential process for life. Consequently, the human body needs an organic system specialized in the elimination of carbon dioxide from the circulating blood and the absorption of oxygen from the atmosphere, at a speed appropriate to the needs of the organism and even at the moment of maximum effort. The respiratory system allows oxygen to enter the body, as well as carbon dioxide to escape. Anatomy    The respiratory system begins in the nose and mouth and continues through the a...
