RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries.

                               HUMAN BLOOD            Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.           Human body has about 5.6 liters (6 quarts) of  blood . This 5.6 liters of  blood circulates  through the body three times every minute. In one  day , the  blood  travels a total of 19,000 km (12,000 miles)—that's four times the distance across the US from coast to coast. Comment down what you want to read next.
