Honestly thought I was going to fail my physiology exam until I started binge watching your videos. My lecturer does not explain things the way you do and the visuals make the learning much easier to comprehend. BLESS THIS CHANNEL!!!!

The thyroid is a small, butterfly-shaped gland that is located in the front of the neck, below the Adam's apple. It is part of the endocrine system, which is a network of glands that produce and release hormones that regulate many functions in the body. The thyroid produces two main hormones, called thyroxine (T4) and triiodothyronine (T3), which control the rate of metabolism, or how the body uses energy. The thyroid also produces a hormone called calcitonin, which helps regulate the level of calcium in the blood. The thyroid needs iodine, a mineral found in some foods and salt, to make its hormones. The production and release of thyroid hormones are controlled by another hormone, called thyroid-stimulating hormone (TSH), which is made by the pituitary gland in the brain. When the thyroid is working properly, it maintains a balance of hormones that keep the body functioning normally. However, sometimes the thyroid can become overactive (hyperthyroidism) or underactive (hypothyroidism), causing various symptoms and health problems. Thyroid disease is a common condition that affects millions of people worldwide. It can be diagnosed with blood tests that measure the levels of thyroid hormones and TSH in the blood. Thyroid disease can be treated with medication, surgery, or radioactive iodine, depending on the cause and severity of the condition.
