Human Body

The human body is a special shell for humans. It is like a shell, inside which most things are very important. But these things are unknown to many of us. The most notable of which is the tantra of the human body. Now the question may come, what is the work of Tantra? Consider an office with hundreds of employees. But a manager is responsible for the overall supervision and management of their work. Similarly, all the functions of our body are governed by this Tantra.

There are total 11 tantras in the human body. Notable tantras are,

1. Digestive system

In the biochemical process in the human body complex food ingredients are broken down with the help of enzymes into simple, soluble and absorbable forms that can be used in the body's metabolism, called digestion. The system through which the process of digestion and absorption is completed is called the digestive system. The alimentary system of the human body consists of the esophagus and associated alimentary glands.

The working steps of the digestive system are as follows:

Food is digested in the oral cavity

This tantra basically starts working when we put a little food in our mouth. The digestive system completes the digestive process such as cutting the food inside the mouth with the help of teeth, secreting and mixing juices from the salivary glands, breaking the food into food particles inside the mouth.

Food is digested in the stomach

Food digested from the mouth stays in the stomach for about 2-6 hours. At this time, digestion of food starts in the stomach. The stomach secretes hydrochloric acid (HCl), which destroys all bacteria in the food. All foods form a kind of paste in the stomach. This state of food is known as Kaim or Mond. As part of chemical digestion in the stomach, the digestive system secretes a type of juice called gastric juice. Later the digested food reaches different parts of the body like liver, duodenum, pancreas.

Thus the alimentary canal or alimentary tract helps in digestion of food.

2. Blood circulatory system

Blood cells move in the human body. Getting blood into the heart, then processing that blood, and finally delivering blood from the heart to different parts of the body—the entire process is handled by the body's system called the circulatory system.

The circulatory system of the human body consists of two types of blood circulation - systemic circulation and pulmonary circulation. In the systemic circulation, blood from the left ventricle of the heart reaches the organs through various vessels, while blood from the organs returns to the right atrium. When the heart expands, the circulatory system pushes the body's blood towards the heart, and when the heart contracts, the blood flows through the arteries and veins of the various tissues and organs of the body. Blood is reabsorbed from the retina and enters the vein through the vena cava.

The pulmonary circulatory system mainly serves as a conduit for the body's blood to be used for lung function. The short cycle of blood circulation by returning blood from the right ventricle to the lungs and from there to the left atrium is called the pulmonary circulation. Gas exchange takes place within the lungs. Oxygen is added to blood by removing carbon dioxide from the blood. After the pulmonary circulation, blood brought to the heart is recirculated throughout the body through the systemic circulation.

The circulatory system is also responsible for the circulation of various blood cells such as red blood cells or erythrocytes, white blood cells or leukocytes, platelets or thrombocytes.

3. Respiratory system

Simple organisms take in oxygen from the environment and transport it directly into body cells or from cell to cell and release carbon dioxide in the reverse way. Advanced animals like humans have specialized respiratory organs for gas exchange. The main respiratory organ of the human body is a pair of lungs. Air enters and exits the lungs through the respiratory system.Through the respiratory system it starts from inside to outside nostrils. All these make up the respiratory system of the human body.

The respiratory system supplies oxygen to the whole body by drawing air into the lungs. There are several important parts of the respiratory system, notable among them are the anterior nostrils, nostrils, larynx, trachea or trachea, bronchus, lungs and alveoli.

Anterior nostrils: Always open and through which air enters the body.

Nostrils: It slightly moistens the air coming from the nostrils. Ciliated and mucous cells trap dust and pathogens. Olfactory cells in the nostrils help in receiving olfactory stimuli.

Larynx: A little higher view of the boy's throat. This elevated part is basically a part of the larynx of the respiratory system, which is called Adam's Apple. The larynx vibrates to produce sound.

Trachea: Also known as trachea, the trachea is like a hollow tube. The trachea connects the lungs to the various parts of the nose.

Lungs: Lungs are the main and largest organ of the respiratory system of the human body. Oxygenated air enters the lungs and carbon dioxide-rich air is exhaled.

Alveolus: Small alveoli form an alveolus. Alveoli are the smallest part of the respiratory system.

4. Excretory System

Nitrogenous waste products produced by metabolism in animal cells are removed from the body in the process of excretion, which is a very rapid and regular process. The human body has a specific organ system known as the Excretory System for the removal of excretory substances. With the help of excretory system, 80 percent of excretory substances go out of the human body. The remaining 10 percent of excreta are not directly excreted but are produced by various activities and excreted through various organs. These are known as accessory excretory organs. Kidney is the main excretory organ of human excretory system.

The functions of the excretory system are-

Removal of nitrogenous waste products from protein metabolism from the blood.

Maintaining water balance in the body and blood

Controlling the amount of various salts in the blood including various minerals such as potassium, calcium, phosphate and chloride

Maintaining the acid-base balance in the blood

Secrete hormones and enzymes

Control blood pressure

The organs included in the excretory system are the kidneys, ureters, renal arteries and veins, bladder and urethra. The numerous nephrons in the kidneys work to purify the blood, while the ureters carry away all the impurities from the blood through the bladder. In addition, the excretory system of the human body also works to protect water and ion balance in the blood, which is called osmoregulation in medical science.

5. Skeletal and Muscular System

The human body contains a type of substance called embryonic mesoderm. From this embryonic mesoderm arises a special type of tissue, essentially a type of connective tissue. The modified form of this connective tissue is bone and cartilage. The skeletal and muscular system, which consists of bones and cartilages, determines the structure of the body, protects the internal soft organs, carries all the weight of the body and helps in the addition of muscles.

Human skeletal system is divided into 2 parts - axial and appendicular. The axial skeleton has a total of 80 bones and the appendages have 126, making up a total of 206 bones. The largest bone in the skeletal system is the femur and the smallest is the stapes, which is located on the ear side of the body.

Functions of the Skeletal System:

Protecting the internal organs of the body

Bones help to store and secrete different types of fat when needed

Produce different types of blood cells

Mineral deposition

Helping to form limbs like hands and feet

Acting as a full body support

There are 3 types of muscles in the muscular system – skeletal muscles or voluntary muscles, cardiac muscles and involuntary muscles.

Helping in movement of various organs

Coordination of different parts of the body to keep its place intact

When the body temperature drops, sometimes the voluntary muscles of the muscular system help to increase the temperature inside the body

6. Nervous System

It is a very common basic characteristic of our human body to respond to stimuli ranging from a small pinch to thousands of stimuli. Along with animal evolution, multicellular organisms appeared. The nervous system of the human body is active all the time for the purpose of making connections with the diverse activities of countless cells spread in the various parts of the body of these multicellular organisms and maintaining good relations with the environment. Nervous system is the system consisting of neurons with the help of which the body manages the body by responding to external and internal stimuli and maintaining the harmony of various physical and physiological functions.

There are 2 types of nervous system - Central Nervous System and Peripheral Nervous System. The brain and spinal cord are parts of the central nervous system of the human body. The function of the central nervous system is to act as the body's main control center and process all incoming and outgoing messages. The peripheral nervous system includes those nerves that carry messages to the central nervous system and back from the central nervous system to different parts of the body.

7. Skin (Integumentary System)

Finally, the largest system of the human body is the integumentary system. This tantra keeps our entire body covered with skin. The elements included in this tantra are - skin, hair, body hair, nails, beard. The way in which the skin system affects our body is as follows-

Dust, water, toxic substances from outside the body block the entry into the body

Controls body temperature

Protects cells, tissues and organs inside the body from external injuries and prevents diseases

Protects the body from dehydration

Helps in the elimination of waste products from the body through sweat

Retains water and fat

carries various stimuli
