Cyanosis occurs when the blood concentration of __________Blank is abnormally high.Multiple Choiceoxyhemoglobinoxygencarbon dioxidedeoxyhemoglobin

Break Down the Problem

1. Identify what cyanosis indicates in the context of blood.
2. Analyze what components of blood can lead to a high concentration that causes cyanosis.

Relevant Concepts

Cyanosis is a condition characterized by a bluish discoloration of the skin and mucous membranes, which occurs when there is an insufficient amount of oxygen in the blood or when blood is poorly oxygenated.

Analysis and Detail

1. Oxyhemoglobin: This is hemoglobin bound to oxygen. High levels would imply good oxygenation, not cyanosis.
2. Oxygen: This is the molecule carried by hemoglobin. Low levels in the blood lead to cyanosis but is not what causes the condition.
3. Carbon Dioxide: An increase can cause respiratory problems but is not directly related to the bluish discoloration of cyanosis.
4. Deoxyhemoglobin: This is hemoglobin without oxygen. Increased levels indicate that hemoglobin is not saturated with oxygen, resulting in the bluish color seen in cyanosis.

Verify and Summarize

• Cyanosis occurs due to insufficient oxygenation of hemoglobin in the blood.
• As deoxygenated hemoglobin accumulates, the skin takes on a bluish color characteristic of cyanosis.

Final Answer

Cyanosis occurs when the blood concentration of deoxyhemoglobin is abnormally high.
