What Do Our Body Cells Do With Oxygen? | Sciencing
Hemoglobin, or red blood cells, are primarily transporters of oxygen. These cells receive oxygen as air is breathed in through the lungs. Oxygen binds itself to these cells, which then carry it to the heart. The heart circulates the oxygenated blood to cells throughout the body in the process of cellular respiration. Temporary Deprivation

How Do Humans Get Oxygen in Their Bodies? | Sciencing
Science ⋅ Biology ⋅ Human Body How Do Humans Get Oxygen in Their Bodies? ••• Updated April 25, 2017 By Veronica Maier Nearly every organism on the planet needs oxygen. Some get it through water and others, like humans, get it through breathing air. Human energy comes from food and oxygen, but food only gives us 10 percent of our energy needs.

For example, the heart and the blood vessels make up the cardiovascular system. They work together to circulate the blood, bringing oxygen and nutrients to cells throughout the body and carrying away carbon dioxide and metabolic wastes. Another example is the respiratory system, which brings oxygen into the and rid of carbon dioxide.

Chapter 2. The Circulatory System and Oxygen Transport. The cardiovascular or circulatory system is designed to ensure the survival of all cells of the body at every moment and it does this by maintaining the immediate chemical environment of each cell in the body (i.e., the interstitial fluid) at a composition appropriate for that …

How does the blood circulatory system work? – InformedHealth.org – NCBI …
In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta). The blood travels from the main artery to larger and smaller arteries and into the capillary network. There the blood drops off oxygen, nutrients and other important substances and picks up carbon dioxide and waste products.
