Blood has less oxygen in it when it travels through the body's tissues and organs, giving up oxygen to cells for energy production. This deoxygenated blood then returns to the lungs, where it picks up more oxygen to be transported to the rest of the body.
Left side of the heart (left ventricle and atrium) has deoxygenated blood, but after its pumped through the lungs and enters the right side of the heart, the blood is oxygenated. If you divide the circulatory system into 'organs', then veins and venules have less oxygen, while arteries and arterioles have more oxygen. With other organs, there should be indistinguishably equal amounts of oxygenated and deoxygenated blood.
Smoking decreases the amount of oxygen that can be carried in the blood by replacing oxygen with carbon monoxide. This makes it harder for oxygen to bind with hemoglobin in red blood cells, leading to lower oxygen levels in the blood of smokers compared to non-smokers.
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
Carbon monoxide is the gas found in cigarette smoke that can bind with hemoglobin in the blood, preventing it from carrying oxygen effectively. This can lead to a decrease in the amount of oxygen delivered to tissues and organs in the body.
The pulmonary circulation is the organ system that exhibits this pattern. Low oxygen levels in the blood cause vasoconstriction in the pulmonary arteries, directing blood flow towards better oxygenated areas. Conversely, high oxygen levels trigger vasodilation, allowing for increased blood flow to areas that need less oxygen.
Blood that has less oxygen is referred to as deoxygenated blood, while blood that has no oxygen is known as venous blood. Deoxygenated blood is typically found in veins returning to the heart, while venous blood is present in the lungs where oxygen is exchanged.
There are multiple factors effecting oxygen carrying capacity of blood. These include:Iron levels,The number of red blood cells (the less there are the less oxygen carrying capacity).Diseases which may damage either the red blood cells or the haemoglobin which is the component which actually carries the oxygen.Hydration level of the person, the less water, the less blood volume the less capacity to carry oxygen!!
If both types of blood is mixed, you get less saturated blood. It will give out oxygen less efficiently. Because oxygen is released according to concentration gradient.
less blood, oxygen and glucose can get to the heart and blood
Ossomosis. The blood travels near the lungs then Oxygen travels from the lungs to the blood. More->Less And the previous blood, does the same with CO2 More->Less.

Varicose Veins 2nd answer: . . . or, blood vessels with less oxygen are veins?
no, the red blood cells carry less oxygen when the person smokes
Iron is needed to produce haemoglobin, which is the part of the blood that carries oxygen throughout the body. A lack of haemoglobin means less oxygen available to be utilised by cells for energy
Reduces the amount of oxygen the blood can carryBody organs receive less oxygen from blood
Smoking decreases the amount of oxygen that can be carried in the blood by replacing oxygen with carbon monoxide. This makes it harder for oxygen to bind with hemoglobin in red blood cells, leading to lower oxygen levels in the blood of smokers compared to non-smokers.
