Blood is a constantly circulating fluid that carries nutrients, oxygen, and waste out of the body. Blood is a liquid that contains a lot of cells and proteins suspended in it. A typical person's blood volume is around 5 liters (more than a gallon).
The blood transports carbon dioxide and other waste products to the lungs, kidneys, and digestive system, where they are expelled from the body. Blood also serves to protect you from sickness and to deliver hormones throughout your body.
Blood cells are divided into three categories.
• Platelets help the blood to clot. Clotting keeps blood from flowing out of the body when a vein or artery ruptures.
• Red blood cells—Assist in the transfer of oxygen throughout the body, these cells. The human body produces these cells at a pace of about 2.4 million per second. Red blood cells are also known as erythrocytes.
• White blood cells—These cells help to keep infections at bay. These cells are essential for boosting your body's immunity. When the body tries to fight illness, it produces more of it. White blood cells are also known as leukocytes.
Some of the signs and symptoms of a shortage of blood in the body include:
1. Pale skin tone
Pale skin is produced by a shortage of hemoglobin in the red blood cells, which causes anemia.
2. Chills in the hands and feet
Cold hands and feet might be caused by a lack of blood. People with insufficient red blood cells have poor blood circulation throughout their bodies because they don't have enough red blood cells to give oxygen to their tissues.
3. Shortness of breath
Low blood pressure can cause shortness of breath, fainting, blacking out, chest pain, and cool, clammy skin.
4. Feeling light-headed
Dizziness, lightheadedness, and the urge to urinate frequently are common symptoms of low blood pressure. The brain does not receive enough oxygen-rich blood when blood pressure is too low, and its function can be impeded.
Fatigue is the most prevalent symptom of a low red blood cell count. If you see any of these symptoms in your body, get to the hospital as soon as possible for treatment.
