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.
oxyhemoglobin (hemoglobin bound to oxygen) is highest in the alveolar venule. This is the initial vessel carrying freshly-oxygenated blood away from the alveolus, which is the air-sac in the lung where gases are exchanged.
because the human blood is red.
About One Hundred quarts in the Human Body
Red blood cells in the human body are normally contained within the blood vessels. They may be stored in the spleen, and are produced in the red marrow.
There is 32 fluid ounces in a quart. There is 29.57 milliliters in a fluid ounce.
The lungs of course
Water
calcium
A concentration of .0070M indicates that there is .007 moles per liter, so in total there are .0336 moles of O2 in the body. This is equal to 1.08 grams or 752 milliliters of O2.
Blood pressure is highest in the arteries.
Examples of homeostatic mechanisms in the body include:internal body temperature regulation,blood-glucose levels,water and ion concentration in the body.
alveoli
The lack of nutrients inside a cell compared to the blood vessel creates a concentration gradient between the blood vessel and the cell. Due to the lower concentration in the cell, the nutrients diffuse through the blood vessel wall and into the cell.
Blood is pumped by the heart.
The normal concentration of glucose in blood is in the range 70-110 mg/100 mL (not mL).5 L blood contain 4,5 g glucose.
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly.
