Virus Tipe A

What is it? The swine flu is a virus that pigs are called Type A influenza virus, with three subgroups: H1N1, H1N2 and H3N2. The time that it suffers from the pig is 7 to 10 days. This virus does not kill pigs. Until now it has been found that patients who suffer from EE. States and Mexico is a variant of the H1N1 sub.

How is it spread? WHO has stated that the transmission of swine influenza is caused by direct contact with an infected pig, and not by the consumption of pork. The truth is that the swine flu virus dies at 70 degrees, minimum temperature of cooked pork.

Symptoms of swine flu in people are similar to those of common flu, muscle pain, malaise, high fever, coughing, sneezing, loss of appetite, diarrhea (cases) and rhinorrhea (dripping from the nose). In case you are sick with the virus of swine influenza a contagious during the first 4-5 days of illness. However, children can spread over 10 days after the swine flu.

Diagnosis of swine flu, we must take a sample of the respiratory system of the person suffering the symptoms in these first 4-5 days and sent to the National Center of Microbiology for their detection.

Treatment of swine flu: until now there is no vaccine to protect us from the variation of the virus is spreading, which is what has been found in Mexico and the U.S. In any event, the swine flu is treated as a common flu, taking antiviral drugs under medical supervision.

The Reproductive System

The reproductive system is a system of organs within an organism which work together for the purpose of reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system.^[1] Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring.^[2]

The major organs of the human reproductive system include the external genitalia (penis and vulva) as well as a number of internal organs including the gamete producing gonads (testicles and ovaries). Diseases of the human reproductive system are very common and widespread, particularly communicable sexually transmitted diseases.^[3]

Most other vertebrate animals have generally similar reproductive systems consisting of gonads, ducts, and openings. However, there is a great diversity of physical adaptations as well as reproductive strategies in every group of vertebrates.

The Circulatory System

The circulatory system is an organ system that transports nutrients, blood gases, hormones, blood cells, waste products, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The most primitive animal phyla lack circulatory system. The lymphatic system, on the other hand, is an open system.

The main components of the human circulatory system are the heart, the blood, and the blood vessels. The circulatory system includes: the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood. An average adult contains five to six quarts (roughly 4.7 to 5.7 liters) of blood, which consists of plasma, red blood cells, white blood cells, and platelets. Also, the digestive system works with the circulatory system to provide the nutrients the system needs to keep the heart pumping.

Two types of fluids move through the circulatory system: blood and lymph. The blood, heart, and blood vessels form the cardiovascular system. The lymph, lymph nodes, and lymph vessels form the lymphatic system. The cardiovascular system and the lymphatic system collectively make up the circulatory system.

Three types of circulation:

Pulmonary circulation is the portion of the cardiovascular system which transports oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated blood back to the hearth,

Systemic circulation is the portion of the cardiovascular system which transports oxygenated blood away from the heart, to the rest of the body, and returns oxygen-depleted blood back to the heart. Systemic circulation is, distance-wise, much longer than pulmonary circulation, transporting blood to every part of the body except the lungs.

coronary circulatory system provides a blood supply to the heart. As it provides oxygenated blood to the heart, it is by definition a part of the systemic circulatory system.

The digestive system

The digestive tract (also known as the alimentary canal) is the system of organs within multicellular animals that takes in food, digests it to extract energy and nutrients, and expels the remaining waste. The major function of the GI tract are ingestion, digestion, absorption, and defecation. The GI tract differs substantially from animal to animal. Some animals have multi-chambered stomachs, while some animals' stomachs contain a single chamber. In a normal human adult male, the GI tract is approximately 6.5 meters (20 feet) long and consists of the upper and lower GI tracts. The tract may also be divided into foregut, midgut, and hindgut, reflecting the embryological origin of each segment of the tract.^[1]

The remainder of this article focuses on human anatomy; see digestion for the process in other organisms.

The Respiratory System

A respiratory system's function is to let gas exchange. The space between the alveoli and the capillaries, the anatomy or structure of the exchange system, and the precise physiological uses of the exchanged gases vary depending on the organism. In humans and other mammals, for example, the anatomical features of the respiratory system include airways,lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood.

The Eye and The Ear

EYE:

Eyes are organs that detect light, and send signals along the optic nerve to the visual and other areas of the brain. Complex optical systems with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system.

The simplest "eyes", such as those in unicellular organism, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms.

EAR:

The ear is the organ that detects sound. The vertebrate ear shows a common biology from fish to humans, with variations in structure according to order and species. It not only acts as a receiver for sound, but plays a major role in the sense of balance and body position. The ear is part of the auditory system.

The Nervous System :) :) :)

The central nervous system is divided into two parts: the brain and the spinal cord. The average adult human brain weighs 1.3 to 1.4 kg (approximately 3 pounds). The brain contains about 100 billion nerve cells ( neurons) and trillons of "support cells" called Glia. The spinal cord is about 43 cm long in adult women and 45 cm long in adult men and weighs about 35-40 grams. The vertebral column, the collection of bones (back bone) that houses the spinal cord, is about 70 cm long. Therefore, the spinal cord is much shorter than the vertebral column.

The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system.

The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

What Prokaryotic and Eukaryotic Cells Have in Common:

• Both have DNA as their genetic material (it’s DNA that tells cells what kind of cells they should be).
  
• Both are covered by a cell membrane.
  
• Both contain RNA.
  
• Both are made from the same basic chemicals: carbohydrates, proteins, nucleic acid, minerals, fats and vitamins.
  
• Both have ribosomes (the structures on which proteins are made).
  
• Both regulate the flow of the nutrients and wastes that enter and leave them.
  
• Both have similar basic metabolism (life processes) like photosynthesis and reproduction.
  
• Both require a supply of energy.
  
• Both are highly regulated by elaborate sensing systems ("chemical noses”) that make them aware of the reactions within them and the environment around them.

Prokaryotic and Eukaryotic Cells Differences:

AGE DIFFERENCES

Scientists believe that prokaryotic cells (in the form of bacteria) were the first life forms on earth. They are considered “primitive” and originated about 3.5 billion years ago. That's 2 billion years earlier than eukaryotic cells and billions of years before our earliest ancestors, the hominids.

Structural Differences

Eukaryotic cells contain two important things that prokaryotic cells do not: a nucleus and organelles (little organs) with membranes around them.

We Can see the structural differences in this page:
http://www.cod.edu/people/faculty/fancher/CellStructure.htm

DNA arrengament

Although both eukaryotic and prokaryotic cells contain DNA, the DNA in eukaryotic cells is held within the nucleus. In prokaryotic cells, the DNA floats freely around in a unorganized manner.

Size
Eukaryotic cells are, on average, ten times larger than prokaryotic cells.

New Discoveries

Until recently, it was thought that only eukaryotic cells existed in multi-cell groups like in organs and tissues. But recent discoveries suggest that some prokaryotic cells do too. This is just one more example of how new discoveries are always changing what we know – or think we know.
