#lung, #alveoli, #bronchus, #respiration, #oxygen, #carbon dioxide, #thoracic cavity, #external respiration, #lung function
The lungs are organs that play a central role in breathing. They are responsible for external respiration — delivering oxygen from the air into the blood and expelling carbon dioxide produced by the body. There is one lung on each side of the heart, and each lung is made up of roughly 500 million alveoli (tiny air sacs).2026-06-26

Syncope is a temporary loss of consciousness that occurs when blood pressure drops suddenly and blood flow to the brain is briefly reduced. It is commonly called fainting. It occurs more often in adolescents and older adults, and caution is needed because injuries can occur when a person falls. Because there are many possible causes, if syncope occurs, please consult a medical specialist to identify the exact cause.2026-06-26

Thyroid Cancer
#thyroid cancer, #papillary carcinoma, #thyroidectomy, #radioactive iodine therapy, #thyroid hormone medication, #levothyroxine, #hypothyroidism, #lymph node metastasis, #thyroid ultrasound
Thyroid cancer is cancer that develops in the butterfly-shaped thyroid gland at the front of the neck. Prognosis varies greatly by type; papillary carcinoma, which accounts for more than 90% of thyroid cancers in Korea, grows slowly and responds well to treatment, so its outlook is relatively favorable. However, some rarer types have a poorer prognosis, so please be sure to decide on an accurate diagnosis and treatment through a medical specialist.2026-06-26
