Neither - it depends where it is in the body
Blood, which is a mix of many components, both cellular and chemical, behaves like many other salty (saline) solutions and freezes at between -2 to -3 degrees celsius.
Red blood cells (RBC) are roundly shaped and have an indent in the middle (like a donut) but no hole. The indent is to increase the surface area of the RBC, thus, making the RBC highly efficient. The function of a RBC is to carry oxygen and other needed nutrients to specific areas of the human body, also is certain parts of the body, carry waste from an area to the liver.
Cholesterol can be both good and bad.It depends on which type of cholesterol is high or low. Low-density lipoprotein (or LDL) very-low-density lipoprotein (VLDL) high-density lipoproteins (HDL). It makes steroids.
Humid, low oxygen, high CO2.
What does high elevated LDL in blood work mean
when a red blood cell come into contact with the oxygen, the hemoglobin present in red blood cell produce a compound named " oxyhimoglobin", and thus it carries oxygen.
no you have oxygen high blood.
Deoxygenated blood is low in oxygen and high in carbon dioxide.
As blood passes through lungs, there is exchange of oxygen and carbon bi oxide, from high concentration to low concentration and oxygen enters the blood from air to blood to make it oxygen rich.
Red blood cell substitutes should have low molecular weight with a high affinity for the oxygen and large surface area. They should be biodegradable, not consume oxygen and should be charge independent to prevent coagulation.
Oxygen.
Athletes need a good supply of oxygen in their blood systems to perform at their highest potential. The more oxygen in the blood stream, the more oxygen is available to be transferred to each cells' mitochondria. The mitochondria produces the energy that a cell needs to perform at its best. So, the more oxygen there is in the blood, the better an athlete will perform. This is why athletes train at high altitudes without much oxygen - so their bodies produce more naturally. Then, when they compete at lower altitudes, their bodies have extra oxygen and thus, they are able to perform better.
When the blood goes around the body, the red blood cells have to unload all these oxygen molecules at places where they are needed, such as at muscle cells carrying out respiration. In the lungs, there's a high concentration of oxygen, relatively low temperature, and less acidic. In such a condition, a red blood cell automatically absorbs oxygen. In the tissues, where respiration is carried out, it's relatively warmer, lower in oxygen concentration and is likely to be more acidic due to a higher concentration of carbon dioxide. Here, the cell is more likely to lose the oxygen. Without any oxygen molecules in the cell, it appears dull red. The pigment inside the cell is now called deoxyhaemoglobin. And the cell is quickly transported back to the lungs to be reloaded with oxygen.
If white blood cell count is high that means the body is responding to an infection.
Same blood as everywhere else. The difference is the gases in the blood: it enters the lungs low on oxygen and high in CO2, it leaves high in oxygen and low in CO2.
The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
Thin cell wall - facilitates permeability of gases and blood. High surface-to-volume ratio
