Vascular system, also called the circulatory system. Look those terms up on wikipedia for more info.
The answer to this is the circulatory system.The ciculatory system because the heart is in the ciculatory system and the blood is the most important thing in the circulatory system.
Circulatory System
The lungs
The Lungs
they supply oxygen to red blood cells, which in turn supplies oxygen to your muscles and brain...which are required to live.
The lungs supplies the bloodstream with oxygen. When we breathe in, out lungs fill with oxygen and that oxygen is taken to the heart to keep our body going.
The organ that supplies a human's bloodstream with oxygen from the air is the lungs. When we inhale, air enters the lungs, and oxygen from the air diffuses into the bloodstream through the alveoli, tiny air sacs where gas exchange occurs. This oxygen-rich blood is then circulated throughout the body to supply tissues and organs.
Their blood systems are separate, but certain materials pass form one to another.Why? There is no direct mixing of the maternal and fetal blood. The blood systems are separate but certain materials pass from one to another, for example, both food and oxygen pass from mother to fetus.
In blood.
chemoreceptors
oxygen if everywhere. In the heart, lungs, blood. YOu need blood everywhere to live!
first we must measure the haemoglobin .each gm. of human hemoglbin carries 1.39ml oxygen in a 100ml blood. in addition o.0003 ml oxygen will be dissolved in blood at 1mmhg pressure of delivered oxygen.
Oxygen is stored in the human body primarily in the lungs and in the red blood cells.
Red blood cell, also known as erythrocyte, carries oxygen to the human body.
