Iran Air, branded as The Airline of the Islamic Republic of Iran (Persian: هواپیمایی جمهوری اسلامی ایران, translit. Havâpeymâyiye Jomhuriye Eslâmiye Irân), is the flag carrier of Iran headquartered on the grounds of Mehrabad Airport in Tehran. As of 2018, it operates scheduled services to 71 destinations in Asia and Europe. Iran Air’s main bases are Imam Khomeini International Airport and Mehrabad Airport, both situated in Tehran, capital of Iran. Domestically, Iran Air is commonly known as Homa, which is the name of a mythical Persian griffin, and also the acronym of Iran National Airlines in the Persian language.
The airline's cargo division, Iran Air Cargo, operates scheduled services internationally using three cargo aircraft.

Iranian Airways was founded in May 1944 by Reza Afshar and Gholam Ebtehaj. Post-war, its first passenger flight was from Tehran to Mashhad, followed by a Tehran-Esfahan-Shiraz-Bushehr-Abadan-Ahwaz service. In 1946 the airline established service to Cairo, Baghdad and Tel Aviv, and in April 1947, to Paris. Between 1945 and 1962, the airline became a major domestic carrier, also operating some international flights to Europe each week. The fleet consisted of Douglas DC-3s initially, supplemented by Douglas DC-4 and Vickers Viscount aircraft later on.
In 1954, the privately owned airline Persian Air Services (PAS) was established. PAS initially operated only freight services, followed by passenger operations between Tehran and other major cities in Iran. In 1960, PAS initiated passenger service to several European destinations, including Geneva, Paris, Brussels and London, using Boeing 707 and Douglas DC-7 aircraft leased from Sabena.
Iranian Airways was nationalized in 1961. On 24 February 1962, Iranian Airways and PAS merged to form the Iran National Airlines Corporation (HOMA), known as Iran Air, using the homa bird as a symbol. HOMA was a public sector venture that combined the two predecessor air carriers. Among the aircraft used were Avro Yorks, Douglas DC-3s, Douglas DC-6s and Vickers Viscounts. The carrier became a full member of the International Air Transport Association (IATA) in 1964. It was the launch customer for the Boeing 747SP.
overview
The Huracán Coupé has been created for unprecedented
performance. All the power and acceleration of a naturally aspirated V-10
engine, without giving up control or fun of driving. This is all thanks to the
all-wheel drive system and the 7-speed Lamborghini Doppia Frizione (LDF)
dual-clutch transmission, as well as the innovative Piattaforma Inerziale
Lamborghini (LPI), created for accurate and real-time detection of all the
chassis movements and for immediate adjustment of the car setup.
Below is a summary of all the characteristics and the technical specifications
of the Huracán Coupé.
Top performance, but also maximum comfort: thanks to Lamborghini's ANIMA (Adaptive Network Intelligence MAnagement) technology, the Huracán can meet all of your driving needs. Each single part recalibrates to provide a driving experience like no other.
By choosing the STRADA setting, you can drive with comfort and maximum grip, perfect for both day-to-day use as well as longer journeys. If you are looking for thrills and fun while driving, then you will appreciate the slight oversteer capabilities of the SPORT setting. On the other hand, to enjoy a racing-style drive, top performance will be delivered by the CORSA setting, which allows the Huracán Coupé to fully express its incredible potential.
The Huracán Coupé's exterior: form follows function, guaranteeing Lamborghini's stylistic purity and performance, so it comes as no surprise that the design is inspired by something as essential as a carbon atom.
From hexagons to streamlined Y's, each of the Huracán's lines is designed to cut through the air and take your breath away. A sporty and dynamic look, both innovative and unmistakably Lamborghini, built to intensify your emotions.
The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body.
It comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet.
The study of the human body involves anatomy, physiology, histology and embryology. The body varies anatomically in known ways. Physiology focuses on the systems and organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis, with safe levels of substances such as sugar and oxygen in the blood.
The body is studied by health professionals, physiologists, anatomists, and by artists to assist them in their work.
The human body is composed of elements including hydrogen, oxygen, carbon, calcium and phosphorus. These elements reside in trillions of cells and non-cellular components of the body.
The adult male body is about 60% water for a total water content of some 42 litres. This is made up of about 19 litres of extracellular fluid including about 3.2 litres of blood plasma and about 8.4 litres of interstitial fluid, and about 23 litres of fluid inside cells. The content, acidity and composition of the water inside and outside cells is carefully maintained. The main electrolytes in body water outside cells are sodium and chloride, whereas within cells it is potassium and other phosphates.
The body contains trillions of cells, the fundamental unit of life.[4] At maturity, there are roughly 30–37 trillion cells in the body, an estimate arrived at by totalling the cell numbers of all the organs of the body and cell types. The body is also host to about the same number of non-human cells[5] as well as multicellular organisms which reside in the gastrointestinal tract and on the skin.[7] Not all parts of the body are made from cells. Cells sit in an extracellular matrix that consists of proteins such as collagen, surrounded by extracellular fluids. Of the 70 kg weight of an average human body, nearly 25 kg is non-human cells or non-cellular material such as bone and connective tissue.
Cells in the body function because of DNA. DNA sits within the nucleus of a cell. Here, parts of DNA are copied and sent to the body of the cell via RNA.[8] The RNA is then used to create proteins which form the basis for cells, their activity, and their products. Proteins dictate cell function and gene expression, a cell is able to self-regulate by the amount of proteins produced.[9] However, not all cells have DNA – some cells such as mature red blood cells lose their nucleus as they mature.
The body consists of many different types of tissue, defined as cells that act with a specialised function.[10] The study of tissues is called histology and often occurs with a microscope. The body consists of four main types of tissues – lining cells (epithelia), connective tissue, nervous tissue and muscle tissue.
Cells that lie on surfaces exposed to the outside world or gastrointestinal tract (epithelia) or internal cavities (endothelium) come in numerous shapes and forms – from single layers of flat cells, to cells with small beating hair-like cilia in the lungs, to column-like cells that line the stomach. Endothelial cells are cells that line internal cavities including blood vessels and glands. Lining cells regulate what can and can't pass through them, protect internal structures, and function as sensory surfaces.
Organs, structured collections of cells with a specific function,[12] sit within the body. Examples include the heart, lungs and liver. Many organs reside within cavities within the body. These cavities include the abdomen and pleura.
The circulatory system comprises the heart and blood vessels (arteries, veins and capillaries). The heart propels the circulation of the blood, which serves as a "transportation system" to transfer oxygen, fuel, nutrients, waste products, immune cells and signalling molecules (i.e., hormones) from one part of the body to another. The blood consists of fluid that carries cells in the circulation, including some that move from tissue to blood vessels and back, as well as the spleen and bone marrow.
The digestive system consists of the mouth including the tongue and teeth, esophagus, stomach, (gastrointestinal tract, small and large intestines, and rectum), as well as the liver, pancreas, gallbladder, and salivary glands. It converts food into small, nutritional, non-toxic molecules for distribution and absorption into the body.
The endocrine system consists of the principal endocrine glands: the pituitary, thyroid, adrenals, pancreas, parathyroids, and gonads, but nearly all organs and tissues produce specific endocrine hormones as well. The endocrine hormones serve as signals from one body system to another regarding an enormous array of conditions, and resulting in variety of changes of function.
The immune system consists of the white blood cells, the thymus, lymph nodes and lymph channels, which are also part of the lymphatic system. The immune system provides a mechanism for the body to distinguish its own cells and tissues from outside cells and substances and to neutralize or destroy the latter by using specialized proteins such as antibodies, cytokines, and toll-like receptors, among many others.
The integumentary system consists of the covering of the body (the skin), including hair and nails as well as other functionally important structures such as the sweat glands and sebaceous glands. The skin provides containment, structure, and protection for other organs, and serves as a major sensory interface with the outside world.
The lymphatic system extracts, transports and metabolizes lymph, the fluid found in between cells. The lymphatic system is similar to the circulatory system in terms of both its structure and its most basic function, to carry a body fluid.
The musculoskeletal system consists of the human skeleton (which includes bones, ligaments, tendons, and cartilage) and attached muscles. It gives the body basic structure and the ability for movement. In addition to their structural role, the larger bones in the body contain bone marrow, the site of production of blood cells. Also, all bones are major storage sites for calcium and phosphate. This system can be split up into the muscular system and the skeletal system.
The nervous system consists of the central nervous system (the brain and spinal cord) and the peripheral nervous system consists of the nerves and ganglia outside the brain and spinal cord. The brain is the organ of thought, emotion, memory, and sensory processing, and serves many aspects of communication and controls various systems and functions. The special senses consist of vision, hearing, taste, and smell. The eyes, ears, tongue, and nose gather information about the body's environment.
The reproductive system consists of the gonads and the internal and external sex organs. The reproductive system produces gametes in each sex, a mechanism for their combination, and in the female a nurturing environment for the first 9 months of development of the infant.
The respiratory system consists of the nose, nasopharynx, trachea, and lungs. It brings oxygen from the air and excretes carbon dioxide and water back into the air.
The urinary system consists of the kidneys, ureters, bladder, and urethra. It removes toxic materials from the blood to produce urine, which carries a variety of waste molecules and excess ions and water out of the body.
