What is the structure of the human body and what is the structure of the human body?

The space of the human body is the site of cell movement and energy regulation, and only when these spaces are pure and the energy flows smoothly can the human body return to nature, restore and maintain health. The movement of cells is closely related to the surrounding environment of cells, and the changes in the pressure and concentration of energy in the space around cells directly affect the opening and closing of cells and radiation. The higher the energy concentration in the surrounding space, the greater the pressure, and the more substances in the cells accumulate, that is, the formation of what is called qi and blood stasis in traditional Chinese medicine, which is the main factor causing cell dysfunction.

The cause of visceral diseases is the inability to evacuate matter and energy, resulting in stasis, that is, the formation of diseases due to the blockage of qi and blood.

The structural hierarchy of the human body is the cellular tissues and organ systems of the human body.

Human anatomy. The basic unit is the cell. There is a non-cellular structure of material between the cells called the interstitium.

Nerve tissue is made up of neurons and glial cells and is highly sensitive and conductive. Neurons are made up of cell bodies, dendrites, and axons. Dendrites are short, branching like branches, and their function is to transmit impulses to the cell body; The axons are long, terminated in nerve endings, and their function is to transmit impulses outward from the cell body.

Myocardial tissue is made up of muscle cells. Muscle cells have the function of contraction. Myogenesis can be divided into skeletal muscles according to morphology and function.

There are three types of smooth muscle and myocardium.

The center of cell metabolism is mainly composed of water, proteins, and ribonucleic acids.

Enzymes, electrolytes.

Isocomposition: Various organelles are also suspended in the cytoplasm. The main organelles are mitochondria and endoplasmic reticulum.

Lysosomes, centrosomes, etc. Nucleus.

It is surrounded by a nuclear envelope and contains nucleolus and chromatin. Chromatin contains nucleic acids and proteins. Nucleic acids are substances that control the heredity of living organisms.

The viscera and the viscera are coordinated with each other, one viscera is matched with the other viscera, the viscera is yin for the inside, and the viscera is yang for the surface. The surface and inside of the viscera are connected by the meridians, that is, the meridians of the viscera are in the viscera, and the meridians and veins of the viscera are in the viscera, and they communicate with each other through the meridians and qi and interact with each other, so the viscera and the viscera can influence each other and change each other on the lesion.

The relationship between the surface and the inside of the viscera is: the heart and the small intestine are on the surface and inside; The liver and gallbladder are on the outside; The spleen and stomach are on the outside; The lungs and the large intestine are on the outside; The kidneys and the bladders are on the outside; The pericardium is in phase with the trifocal phase.

From a micro point of view, it is composed of carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, sodium, potassium, calcium and other elements, it can also be said that the body is composed of water, proteins, fats, carbohydrates and minerals, from a macro point of view, the body is composed of bones, muscles, fat, blood, hair, etc.

The basic unit of the human body structure is the cell, and there is a non-cellular structure between the cells called the interstitium. The cell structure can be divided into three parts: the cell membrane, the cytoplasm, and the nucleus. Epithelial tissue is divided into three categories: overlying epithelium, glandular epithelium, and sensory epithelium.

The position of the human body ** proportions ---

The navel of a person is located at the **dividing point of the human height.

Above the navel, the neck is the ** dividing point;

The knee below the navel is the **dividing point.

Most of the beauties with graceful figures fit this ratio.

Human body"of"**Proportion.

1. The ratio of the upper and lower body: with the navel as the boundary, the ratio of the upper and lower body should be 5 to 8, in line with the law of "** segmentation".

2. Chest circumference: Measure the chest circumference from the fullest part of the armpit along the top of the chest, which should be half of the height.

3. Waist circumference: under normal circumstances, measure the thinnest part of the waist. The waist circumference is 20 cm smaller than the chest circumference.

4. Hip circumference: the pubic bone in front of the body is parallel to the largest part of the buttocks. The hip circumference is 4 cm larger than the chest circumference.

5. Thigh circumference: at the uppermost part of the thigh, below the hip fold. The thigh circumference is 10 cm smaller than the waist circumference.

6. Calf circumference: at the fullest part of the calf. The calf circumference is larger, and the thigh circumference is 20 cm smaller.

7. Foot and neck circumference: in the thinnest part of the foot and neck. The foot and neck circumference is smaller, and the leg circumference is 10 cm smaller.

8. Upper arm circumference: in the middle between the shoulder joint and the elbow joint. The upper arm circumference is equal to half of the thigh circumference.

9. Neck circumference: the thinnest part of the middle of the neck. The neck circumference is equal to the calf circumference.

10. Shoulder width: the distance between the two shoulder peaks. The width of the shoulders is equal to half of the chest circumference minus 4 cm.

Whew! Seeing how hard I've worked, give it to me!!

Cells are the basic units of morphological structure, physiological function, and growth and development of the human body. Many groups of cells with similar morphology and function together with varying numbers of extracellular matrix make up the tissue. According to the different structure and function, human tissues can be divided into four types:

Epithelial, connective, muscular, and nervous tissues. They are organically combined in a certain way to form organs with a certain form and complete specific functions. We call the organs with large cavities hollow organs, such as the heart, stomach, bladder, etc.; Those without large cavities are called solid organs, such as liver, spleen, kidney, etc.

Many functionally related organs are connected together to perform a certain continuous physiological function, i.e., to form a system. The human body can be divided into nine major systems, namely the locomotor system, digestive system, respiratory system, urinary system, reproductive system, endocrine system, vasculature, sensory organs, and nervous system. Among them, most of the organs of the four systems of digestion, respiration, urinary and reproductive are located in the thoracic, abdominal and pelvic cavities, and are all connected to the outside world by holes, fissures or pipes, mainly for material metabolism and reproduction of offspring, collectively referred to as internal organs.

Although all organs and systems of the human body have their specific functions, they are interconnected and closely coordinated under the regulation of nerves and body fluids, and together constitute a complete and unified human body.

Human body structure: The basic unit is the cell.
