MICROANATOMY

Detailed explanation-1: -The left atrium sends the oxygenated blood into the left ventricle (lower chamber). This muscular part of the heart pumps blood out to the body through the arteries. As it moves through your body and organs, blood collects and drops off nutrients, hormones and waste products.

Detailed explanation-2: -Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell.

Detailed explanation-3: -Your circulatory system, also called the cardiovascular system or vascular system, transports oxygen, nutrients and hormones to your body’s cells to use for energy, growth and repair.

Detailed explanation-4: -Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism, and reproduction. The endocrine system regulates how much of each hormone is released.

Detailed explanation-5: -The hormones travel in the blood circulation to reach their target sites (cells, tissues or organs) they can also travel in the lymphatic system when they are destroyed in the liver and removed by the kidneys.
