1, the ratio of upper body to lower body: navel as the boundary. The ratio of upper body to lower body should be 5 to 8.

2. bust: measure the bust along the chest from the fullness above the armpit. It should be half the height.

3. Waist circumference: Under normal circumstances, measure the thinnest part of the waist. Waist is 20 cm smaller than bust.

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

5, thigh circumference: above the thigh. Below the hip fold line. The thigh circumference is smaller than the waist circumference 10 cm.

6, calf circumference: calf fullness. The calf circumference is 20 cm smaller than the thigh circumference.

7. Foot neck circumference: at the thinnest part of the foot neck. The ankle circumference is smaller than the leg circumference 10 cm.

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

9. Neck circumference: The thinnest part in the middle of the neck. Neck circumference equals calf circumference.

10, shoulder width: the distance between two acromions. The shoulder width is equal to half the bust minus 4 cm.

The human body is a human body, and its main components are head, neck, trunk, arms and legs. In general biology or medicine, the human body includes not only the above-mentioned parts, but also internal organs such as respiratory system, cardiovascular system and nervous system, and each part is composed of cells.

The surface of human body is skin. There are muscles and bones under the skin. In the head and trunk, skin, muscles and bones enclose two large cavities: cranial cavity and body cavity, and the cranial cavity is communicated with the spinal canal in the spine.

There is a brain in the cranial cavity, which is connected with the spinal cord in the spinal canal. The body cavity is divided into upper and lower cavities by the diaphragm: the upper cavity is called the chest cavity, which contains organs such as heart and lung; The lower part is called abdominal cavity, and the lowest part of abdominal cavity (that is, the part in pelvis) is also called pelvic cavity. There are organs such as stomach, intestine, liver and kidney in abdominal cavity, bladder and rectum in pelvic cavity, ovary and uterus in women.

Skeleton structure is the key to human body structure, which determines the length of human body proportion, the size of body shape and the growth form of each limb in appearance. There are about 206 bones in the human body, which constitute the scaffold of the human body.
