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 respiratory system brings in atmospheric air, which is ~21% oxygen, and allows the oxygen to diffuse into the blood stream. This is also where carbon dioxide from the body is allowed to diffuse out of the blood stream into the lungs where it is then expelled back into the atmosphere.
Circulatory System
The respiratory 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.
I think that its in the brain. Our brain cannot function, and so those our whole body(except for the heart?), if it did not get blood that supplies oxygen.
These are collectively referred to as "physical capital" or "tangible assets." This includes resources such as buildings, machinery, technology, and tools that contribute to the production of goods and services. In contrast, "human capital" refers to the skills, knowledge, and experience of individuals that also contribute to the productivity and success of an organization.
the blood absorb oxygen in the lungs(cappilaries)
In blood.
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.
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.
Its carries "oxygen rich blood" away from the heart.
