our thyroid glands plays a main role in a human body. It secretes thyroxine and calcitonin. In which thyroxine help in growth and cellular metabolism and calcitonin helps to regulates calcium concentration in blood . If thyroid gland stops working then there is low level of calcium in our blood, which leads to mental and hormonal disorder. In this way a person's blood calcium level would be affected if his/her thyroid gland stops working.
LDL (low-density lipoprotein) carry cholesterol from the liver to the tissues and can contribute to the formation of plaque that builds up in the arteries.
<h3>What are lipids?</h3>
Lipids are soluble in fat and to circulate in the blood, which is an aqueous medium, they form lipoprotein complexes called lipoproteins, these constitute a transport medium and circulating reservoir for lipids.
<h3>Characteristics of LDL (low-density lipoprotein)</h3>
- Low-density lipoproteins, composed of 50% triglycerides, are the ones that transport the lipids synthesized in the liver to other parts of the body.
- LDL, composed mainly of cholesterol, when in excess, also deposits it on the walls of the arteries, contributing to the formation of plaque.
Therefore, we can conclude that excess LDL (low-density lipoprotein) poses a health risk because it facilitates the accumulation of fat in the arteries.

what's the question i don't understand
Shivering
Explanation: shivering action is an act to warm a homoeothermic body. Sweating makes the body cool, panting don’t keep body warm and dilating blood vessels does not keep body warm instead constriction of blood vessels is the initial process to conserve body heat followed by waves of muscle contraction, which is nothing but shivering. Alteration of the set point in torpor is also not the right answer
