The O2 in seawater approaches the saturation value of 9.1 mg/L. This value changes with depth and water temperature.

Indigenous mountain animals like the llama, alpaca, and vicuña in the Andes or the yak in the Himalayas are adapted rather than acclimatized to the low oxygen partial pressures of high altitude. Their hemoglobin has a high oxygen affinity, so that full saturation of the blood with oxygen occurs at a lower partial pressure of oxygen. In contrast to acclimatized humans, these indigenous,...
The component of plasma that maintains the osmotic pressure of blood is protein. The protein albumin and others maintain osmotic pressure in blood.

The component of blood that contains iron and binds with oxygen is hemoglobin. Hemoglobin is a protein found in red blood cells that carries oxygen from the lungs to the rest of the body, and carbon dioxide back to the lungs for exhalation.
The partial pressure of oxygen in tissue is lower due to oxygen being delivered from the blood to the tissues for cellular respiration. As tissues consume oxygen for metabolic processes, the partial pressure decreases. Additionally, factors like distance from capillaries and tissue oxygen consumption rate impact the partial pressure of oxygen in tissues.
The normal partial pressure of oxygen in arterial blood is 75-100 millimeters of mercury. In comparison the partial pressure of oxygen at sea level is 750 millimeters of mercury.

Yes, the partial pressure of oxygen in the arteries is typically greater than in the veins. This is because oxygen is being delivered to tissues by the arterial blood, so the arterial blood has higher oxygen levels compared to the venous blood, which has already passed through the tissues and picked up carbon dioxide.
Yes, PaO2 (partial pressure of oxygen in arterial blood) and pO2 (partial pressure of oxygen) are the same. PaO2 specifically refers to the measurement of oxygen in arterial blood, while pO2 is a more general term referring to the partial pressure of oxygen in any context.
Partial pressure affects the movement of oxygen from the alveoli to the blood because it is the main driving force for oxygen movement in the lungs.Oxygen passes from the air to the fluid within the alveoli, into the cell of the alveoli.
To find the partial pressure of oxygen, we need to subtract the partial pressures of nitrogen and CO2 from the total pressure of the mixture, which is typically around 760 mmHg at sea level. Therefore, the partial pressure of oxygen would be 760 - 630 - 39 = 91 mmHg.
The normal partial pressure of oxygen in the systemic veins at sea level is around 40 mmHg. This value indicates the pressure exerted by oxygen molecules in the blood and corresponds to the oxygen content in the venous blood returning to the heart.

PaO2 is the partial pressure of oxygen in arterial blood. Pa is the abbreviation of partial.
The partial pressure of oxygen in the interstitial space of peripheral tissues is typically around 40 mmHg. This level is lower than the partial pressure of oxygen in arterial blood, which is around 100 mmHg. Oxygen diffuses from blood capillaries into the interstitial space to reach cells for metabolism.
