What Is The Instruction Manual For Our Body?

If you want to know, what is the instruction manual for our body? In this article, I will tell you. You should read this very carefully.

What is the instructional manual for our body?

An instruction manual is necessary for our human body. We should follow it.

If you follow the manual of our body then you can learn about the parts of the human body.

You could learn more about yourself.

You will introduce DNA, Genes, Chromosomes, etc. “Instructional manual for our body” is a book name. You can buy it from Amazon Kindle.

Learn to recognize the parts of the human body and their functions

From a first glance, most of us could mention the basic parts of the human body: head, neck, trunk, arms and legs (extremities).

But this is a cursory glance; digging a little deeper, the list of parts of the human body becomes very extensive.

Life systems of Human body partsLife systems of Human body parts

To make the approach to this topic more functional, we are going to talk about the parts of the body based on the systems in which they are organized.

Cardiovascular system

Its main function is to carry oxygen and nutrients to all cells of the human body. The cardiovascular system is made up of the heart, veins, and arteries.

Digestive system

It is responsible for transforming food into nutrients that can be used by our bodies to function and develop.

It is made up of the mouth, throat, oesophagus, stomach, small intestine, large intestine, rectum, and anus.

The liver and pancreas also serve important functions in the digestive system.

Endocrine system

Together with the nervous system, they constitute the main regulatory systems of the human body.

It is made up of glands and the hormones they secrete.

Immune system

Many consider the immune system our most complex system after the nervous.

Among its main functions is to neutralize the action of viruses, bacteria and fungi that enter our body and eliminate them, as well as the fight against the cells of the body that have a pathological effect due to disease.

It is made up of the lymphoid organs (thymus, lymph nodes, spleen, bone marrow, among others that make up the lymphatic system ), immunocompetent cells (granulocytes, macrophages, lymphocytes) and the substances that these cells produce.

Muscular system

There are three different types of muscles system:

  • Skeletal or striated muscle, which produces voluntary movements.
  • Visceral or smooth muscle, allows the mobility of structures such as the digestive tract.
  • Cardiac muscle, shares properties with striated and smooth muscle.

The muscular system is necessary not only for the movement of our body in space and to maintain posture but also for the functioning of vital organs, such as the heart.

Skeletal system

Made up of bones, tendons, ligaments, and cartilage, the skeletal system constitutes a defence barrier for our internal organs.

In addition, this system allows mobility, serves as a calcium store and is involved in the production of blood cells.

Renal System

In charge of eliminating the waste produced by our body, it also intervenes in the regulation of electrolytes and the acid-base balance.

This part of the human body is made up of two kidneys, the renal pelvis, the ureters, the urinary bladder, and the urethra.

Reproductive system

A system that allows reproduction and continuity as a species. It is constituted in man by:

  • Testicles
  • Genital ducts
  • Urethra
  • Prostate
  • Seminal vesicles
  • Penis

In women the reproductive system is composed of:

  • Ovaries
  • Uterus
  • Uterine tubes
  • Vagina
  • Vulva

Respiratory system

In charge of obtaining oxygen from the external environment to carry it to all tissues and organs and to expel carbon dioxide.

The respiratory system is made up of the nose, mouth, pharynx, larynx, trachea, lungs, bronchi, bronchioles, and pulmonary alveoli.

Integumentary system

In humans, it is made up of the skin, hair, nails, sweat and sebaceous glands.

Its functions include being the first defence barrier against environmental damage and the synthesis of vitamins such as D, as well as intervening in thermal regulation.

Nervous system

The most complex of body systems, responsible for our development, knowledge and interaction with the environment. The nervous system is divided into:

  • The Nervous system at the centre is made up of the brain and spinal cord.
  • The peripheral nervous system includes the sensory and motor nerves.
  • The autonomous nervous system is in charge of vegetative functioning.

Frequently asked questions (FAQ)Frequently asked questions (FAQ)

How do citrus fruits act on tooth enamel?

As with alcoholic beverages, citrus fruits have acids that demineralize tooth enamel.

This demineralization can lead to tooth erosion and tooth decay.

Dental caries are characterized by the destruction of tooth structure as a result of acid-induced demineralization that causes plaque.

What other foods in the diet can affect enamel and how do they do it?What other foods in the diet can affect enamel and how do they do it

Sugary drinks such as soft drinks, energy drinks, alcoholic drinks, or industrial juices directly affect the enamel.

The consumption of these drinks together with poor dental hygiene can compromise the health of our tooth enamel. They also affect foods high in carbohydrates and sugars.

What foods can help us to have a healthy tooth enamel?What foods can help us to have a healthy tooth enamel

Dairy foods are very beneficial for the recovery of tooth enamel as they provide a significant amount of calcium.

Milk, yoghurts and cheese are great allies when it comes to strengthening the health of our teeth.

Green tea is also a very important food for dental strength as it has an antioxidant that prevents the action of bacteria on the gums and reduces the development of tartar on the teeth.

Fruits and vegetables are beneficial for our tooth enamel. Gum or candies without sugar and with xylitol helps to clean the mouth after meals.

If tooth brushing is impossible, gum stimulates saliva secretion. Saliva is a natural protection that we have against cavities.

What effects can whitening home remedies have on enamel?

Baking soda should not be used together with toothpaste as it can be highly abrasive and damaging. Overuse can end up damaging the enamel irreversibly.

If you want to whiten your teeth responsibly and safely, we should opt for products such as hydrogen peroxide or carbamide peroxide that dentists use for teeth whitening treatment.
