How does blood carry oxygen around the body?

Answer 1

The blood moves around the body inside the circulatory system. This is made up of arteries, veins and capillaries. The blood keeps moving through these blood vessels because it is pumped by the heart. Valves prevent the blood from flowing backwards. The blood always circulates through the body in the same direction.

Answer 2

Blood carries oxygen around the body by binding it to hemoglobin, a protein in red blood cells. When blood reaches the lungs, oxygen molecules bind to hemoglobin and are transported to cells throughout the body. Hemoglobin releases oxygen to tissues in need as it circulates through the bloodstream.

Answer 3

Blood cells contain hemoglobin (a protein with iron in it) that binds to oxygen such that it releases the oxygen as pH decreases. This is a good thing as active tissue release C02 which increases the free H+ thus effectively moving oxygen from the lungs to the active tissue.

Answer 4

It is carried by the red blood cells.

Red Blood cells contain hemoglobin, an iron-based molecule that will hold oxygen and carry it. The main function of red blood cells is to take oxygen from the lungs to the cells of the body. It can also bind other gases, carrying away the carbon dioxide given off by the cells during metabolism. (Another is carbon monoxide, a toxic gas that can cause death when it takes the place of oxygen.)

Oxygen is released from the red blood cell in the capillaries (the smallest blood vessels in the body) to the cells of the body. About 97 percent of the oxygen that is carried by the blood from the lungs is carried by hemoglobin; the rest is dissolved in the plasma. Hemoglobin allows the blood to transport 30 to 100 times more oxygen than can be dissolved in the plasma without red blood cells.

Hemoglobin combines with oxygen in the lungs, where oxygen levels are high, and this is then easily released through the walls of the capillaries, where the oxygen level is low. Each molecule of hemoglobin contains four iron atoms, and each iron atom can bind a one molecule of oxygen (which contains two oxygen atoms, called O2) for a total of four oxygen molecules (4 * O2) or eight atoms of oxygen for each molecule of hemoglobin. The iron in hemoglobin gives blood its red color.

Answer 5

Oxygen is carried throughout the body by red blood cells, located in the blood.

Answer 6

Oxygen is absorbed by red blood cells and is transported around the body in the blood.

Answer 7

Oxygen combines with Haemoglobin protein in erythrocytes forming oxi-haemoglobin and haemoglobin carries oxygen around the body and releases when necessary.
