Red blood cells (RBCs), also known as erythrocytes, are specialized cells in the blood responsible for carrying oxygen from the lungs to the body's tissues and returning carbon dioxide from the tissues to the lungs. RBCs contain hemoglobin, a protein that binds to oxygen molecules. Hemoglobin is composed of four subunits, each containing an iron ion that can bind one molecule of oxygen. This binding and release of oxygen are critical for cellular respiration, which provides energy for the body's metabolic processes. The unique biconcave shape of RBCs increases their surface area for efficient gas exchange and allows them to navigate through the narrow capillaries.

Anemiais a condition characterized by a deficiency of red blood cells or hemoglobin in the blood, leading to a lack of oxygen being carried to the body's tissues. This can result from a deficiency of iron, vitamin B12, or folate, among other causes. The other options refer to different conditions:

Angina: Chest pain caused by reduced blood flow to the heart.

Ischemia: Restricted blood supply to tissues, causing a shortage of oxygen needed for cellular metabolism.

Under the Controlled Substance Act, there are five schedules. These schedules classify drugs based on their potential for abuse, accepted medical use, and safety or dependence liability.

Vitamin D is essential for the body's ability to absorb calcium from the diet. It promotes the absorption of calcium in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone. Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Vitamin D is obtained from exposure to sunlight, dietary sources (such as fatty fish, fortified dairy products, and eggs), and supplements. It is converted in the skin to its active form, calcitriol, which facilitates calcium absorption in the intestines.
