How does blood flow in the body
How does blood flow in the body
The blood moves in the body in a specific way, which does not change, and in the following is the way blood flows through the body:
Veins serve to bring blood to the right side of the heart.
Then the pulmonary arteries carry blood to the lungs, so that it receives oxygen.
The pulmonary veins carry oxygen-rich blood to the left side of the heart.
The aorta, which is the main artery in the body, carries blood from the left side of the heart to the rest of the body through many branches of the arteries.
Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide, and waste products to pass into and out of tissue cells.
The veins then carry the blood back to the heart, and the process begins again.
vascular function
The function of the blood vessels is to deliver blood to the organs and tissues in the body, and the blood provides them with the oxygen and nutrients they need for work, and the blood vessels also transport waste and carbon dioxide away from the organs and tissues of the body, and it is worth noting that each type of vessel The blood vessels perform a different function, and the following is an explanation of it:
Arteries: They are strong and muscular blood vessels, and they carry oxygen-rich blood from the heart to the body, and they deal with a large amount of force and pressure as a result of blood flow, but they do not carry a large amount of blood, as only about 10% to 15% of The body’s blood is in the arteries.
Capillaries: They are tiny blood vessels that have thin walls. Oxygen and nutrients in the blood can travel through the walls to reach the organs and tissues. They also work to get rid of waste in the tissues. It is worth noting that the capillaries are the place where exchange takes place. Oxygen and nutrients to carbon dioxide and waste.
Veins: unlike arteries, veins do not have to carry high pressure blood, but they must carry large amounts of deoxygenated blood to the heart, and the thinner, less flexible walls help to deal with large volumes and low pressure, and most veins include Valves that open and close, which control the process of blood flow and maintain the flow in one direction, as approximately 75% of the blood is in the veins.
How to rid the body of toxins
How to rid the body of toxins
Our bodies need from time to time to cleanse to remove the toxins present in our bodies, which mostly come as a result of eating fast foods and non-food meals that contain nutrients that the body does not need. Among those systems that can be followed to rid the body of toxins are the detox system, of which there are two systems. Short-term for a number of days and a long-term system, and when you achieve the two systems together, you will feel a big difference in the improvement of general health as a result of the body regaining its strength and expelling its toxins and microbes, that system treats some diseases resulting from wrong nutrition and the abundance of sugars and foods Fast foods contain large amounts of empty calories that only provide the body with fat.
First, the short-term detox diet, which includes three different diets:
The fruit system: the system relies on fasting from food without starving the soul and eating fruits only in quantities that raise energy levels within the body as it helps prevent strokes and effectively expel toxins from the body. Fruits such as light yellow lemon are eaten in this system. And green lemons as juices, oranges, tangerines, and grapefruit, and do not eat anything but fruits for 7 days, as they are useful for expelling toxins and permanently from the body because they contain cleaning properties. Blueberries can be relied upon to contain vitamin C.
– Fluid system: the person depends on taking his daily food, but through some liquids such as green tea, vegetable and fruit juices such as pineapple, orange, apple, and vegetables such as tomatoes, carrots, parsley, and celery in the form of juice and many others. This system is also useful not Not only in expelling toxins from the body, but also in losing weight. Do not rely on this system for only three days. Try to vary between the colors of juices for more effectiveness and supplying the body with the nutrients necessary to build it. Expulsion of toxins must be done without any stress on the body.
Eat only fruits and vegetables: eat vegetables that contain fiber, such as legumes, beans of all kinds, peas, soybeans, artichokes, leafy vegetables, and potassium found in bananas, potatoes and spinach. Vitamin C is found in broccoli, strawberries, kiwi and tomatoes. Folic acid is found in cowpeas. And asparagus and useful fats in mushrooms and coconut, and many other examples. Eating fruits and vegetables for seven days every once in a while is enough to expel all toxins from the body. This step is useful for those who suffer from constipation resulting from improper nutrition.

Second, the long-term detox system:
It is the dietary traditions that we must follow in our eating habits on a daily basis, and they are useful for expelling toxins from the body in a more than excellent way:
First: Drinking enough water, as water is one of the most important elements that help expel toxins from the body, so two liters of water per day helps in kidney and liver dialysis and revitalizes the functions of each of them.
Second: Eating organic vegetables and meat that do not have chemical fertilizers or animals that have not been injected with growth hormones. Organic vegetables can be grown in your home very easily.
Third: Avoid white poison Sugar and salt Avoid excessive intake of processed sugar and salt, which are the most important and biggest factors that cause the destruction of the body.
Fourth: Stay away from drinking carbonated water because it causes osteoporosis and empty calories.
Fifth: exercise, yoga and meditation.
Sixth: Keeping away from places filled with toxic gases.
This system will rid you of harmful toxins in the body if you follow the two systems
the secret between lack of sleep and the ability to focus
American scientists confirmed that a mutation in one of the genes allows some people to regain their activity and get enough rest without the need for long hours of sleep.
Most people need at least six hours of continuous sleep to restore their activity and ability to focus, but US researchers discovered the existence of a “genetic variable” in some people that makes little sleep enough to restore their activity and carry out their daily duties.
According to the study conducted by researchers at the Children’s Hospital in Philadelphia on 100 pairs of twins, and its results were published in the scientific journal “Sleep”, it was found that the twins who carry a copy of this variable gene “BHLHE41” averaged about 5 hours of sleep at night only, i.e. less About an hour ahead of their peers who do not carry this genetic variant.
The researchers confirmed that the twins who had this genetic variant “BHLHE41” missed 40% less in the concentration test, after depriving them of 38 hours of sleep, and they needed only 8 hours to recover full activity after completing the experiment, while their peers who did not carry this variant. Genie to 9.5 hours to recover.
Scientists found that the genetic variant does not give its owner a different quality of sleep, but rather helps regulate the internal biological clock, so that its number decreases to reach a quality of sleep that gives better memory and better recovery of physical and mental activity. According to Prof. Professor “Timothy Morgenthiral,” President of the American Academy of Sleep Medicine, the need for sleep is linked to a biological factor and is not subject to the personal desire of the individual.
Beware of the dangers of eating burnt food to your health
Toast or charred meat may be something you love to eat, but you should avoid eating burnt food to stay healthy, so in this report we learn about the risks of eating burnt food to your health, according to the “Health” website.
Should you avoid eating burnt food?
Once we start cooking, we see the food undergo changes. Not only does it become softer, but it also undergoes a number of chemical changes during cooking, all of which help make it suitable for eating.
It turns out that heat speeds up chemical reactions, which have both positive and negative effects on a meal. In addition to making food more difficult to digest and metabolize, overcooking can also cause food to burn. It releases compounds like acrylamide that aren’t healthy for us.
During high-temperature cooking methods, acrylamide can form in certain foods such as potatoes, cereals, coffee, and bread.
According to the Food and Drug Administration, this substance has been shown to cause cancer in animals exposed to very high doses of acrylamide but there is no consistent evidence of the effect of acrylamide from food consumption on cancer in humans.
However, acrylamide is considered a human health concern by the US National Toxicology Program and the Joint FAO/WHO Expert Committee on Food Additives. Burned Food and Acrylamide
Although there are benefits to steaming, the formation of acrylamide can be stimulated by several conventional cooking methods. They include cooking methods such as baking, grilling, frying, or roasting. However, since they use less oil, these cooking methods are touted as healthy.
Although there is not enough evidence that acrylamide can cause cancer, the expert recommends eating fresh fruits, vegetables, and high-fiber foods and avoiding high-sugar, salty, fatty, and processed foods to stay healthy. You can also try cancer-preventive foods.
There are some people who like to eat burnt food because it enhances the flavour.
Cooking at home can be easy and healthy, but always keep an eye on the time. Nutritional losses increase with cooking time because some vitamins are more sensitive to heat. Here’s what to do when using high-heat cooking methods
• While using high heat cooking techniques, it is important to cook food only until golden brown and not dark brown or burnt.
