what is the no of RBC in human body
Answers
here's your answer ❣️
Adult humans have roughly 20–30 trillion red blood cells at any given time, constituting approximately 70% of all cells by number. Women have about 4–5 million red blood cells per microliter (cubic millimeter) of blood and men about 5–6 million; people living at high altitudes with low oxygen tension will have more.
hope it's helpful for you ☺️

Answer:
Your answer is approximately 20 - 30 trillion.
Explanation:
Red blood cells (RBCs), also referred to as red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes (from Greek erythros for "red" and kytos for "hollow vessel", with -cyte translated as "cell" in modern usage), are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O2) to the body tissues—via blood flow through the circulatory system. The cells develop in the bone marrow and circulate for about 100–120 days in the body before their components are recycled by macrophages. Each circulation takes about 60 seconds (one minute). Approximately 84% of the cells in the human body are 20–30 trillion red blood cells. Nearly half of the blood's volume (40% to 45%) is red blood cells.
