Venous blood glucose level will be approximately 10-15% higher.

Because the glucose in capillary blood is not fully delivered to the cells yet. Once the blood leaves the capillary and enters the vein, the glucose has then been delivered to the cells and the blood is considered used.
The primary differences between venous blood and arterial blood are that arterial blood is oxygenated, under great pressure, and is moving from the heart, and that venous blood is deoxygenated, under low pressure, and is moving towards the heart.
Pressure at capillary bed varies from 32mmHg at the arteriolar end to about 10mmHg at venous end, with an average of 17mmHg
Arterial bleeding is more serious than venous or capillary bleeding because arteries carry blood with higher pressure and oxygen content, causing them to spurt or gush out more rapidly. This can lead to a faster blood loss and potential life-threatening situations if not controlled promptly. Arterial bleeding can result in more severe blood loss and tissue damage compared to venous or capillary bleeding.
A portal system is a special type of blood circulation where blood from one capillary bed flows into a second capillary bed before returning to the heart. The hepatic portal system, for example, carries nutrient-rich blood from the digestive organs to the liver for processing. This differs from normal venous return flow where blood goes directly from capillaries to veins and then back to the heart.
Arterial bleeding is considered more serious than venous or capillary bleeding because arteries carry oxygen-rich blood at high pressure from the heart to the rest of the body. This type of bleeding can lead to rapid blood loss and can be life-threatening if not controlled quickly. Venous and capillary bleeding, on the other hand, typically involve blood flowing out at a slower rate and are easier to manage.
yes bcz O2-bound heamoglobin (called oxyheamoglobin) is bright red in colour.
blood is never blue but arterial blood lacking oxygen is darker... venous blood is dark red arterial blood is bright red capillary blood is brick red
Venous blood is preferred for testing because it provides a more accurate representation of the body's overall health compared to capillary blood. Venous blood contains a higher concentration of important substances like glucose, oxygen, and hormones, making it more reliable for diagnostic purposes. Additionally, venous blood is easier to collect in larger quantities, which is often necessary for a wide range of laboratory tests.
