What does bright red blood indicate quizlet?
what does the bright red color of blood indicates? it indicates that hemoglobin carrying oxygen.
What does dark red blood indicate quizlet?

What is the average lifespan of a red blood cell and how does its Anucleate condition affect this life span?
Mature erythrocytes circulate for 120 days despite having almost no capacity for either repair or regeneration of damaged or worn-out components. This longevity is remarkable considering the mechanical, metabolic, and geometric challenges the circulation presents.
What happens when an ABO blood type is mismatched for the first time quizlet?
What happens when an ABO blood type is mismatched for the first time? antibodies bind together causing blood to clump up, and the blood will not work properly.
Is blood blue when deoxygenated?
Anyone who has donated blood or had their blood drawn by a nurse can attest that deoxygenated blood is dark red and not blue. The blood in your veins appears blue because you are looking at your veins through layers of skin and fat according to Alwin Kienle in his paper "Why do veins appear blue?
Which condition is characterized by an abnormal increase in red blood cell count?
Polycythemia vera is a rare, chronic disorder involving the overproduction of blood cells in the bone marrow (myeloproliferation). The overproduction of red blood cells is most dramatic, but the production of white blood cells and platelets are also elevated in most cases.
What are two conditions that cause polycythemia?
Apparent polycythaemia is often caused by being overweight, smoking, drinking too much alcohol or taking certain medicines – including diuretics (tablets for high blood pressure that make you pee more). Apparent polycythaemia may improve if the underlying cause is identified and managed.
What causes Macrocytic Hypochromic anemia?
What causes macrocytic anemia? People may develop macrocytic anemia when they don't get enough vitamin B12 and/or folate (vitamin B9) to create healthy red blood cells, or they have medical conditions that prevent their bodies from absorbing those nutrients.
What determines the color of blood?
Human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that's crucial for carrying oxygen through your bloodstream. Heme contains an iron atom which binds to oxygen; it's this molecule that transports oxygen from your lungs to other parts of the body.
What blood type is the universal donor?
O negative blood type Universal donors are those with an O negative blood type. Why? O negative blood can be used in transfusions for any blood type.
What does bright red blood mean?
The colors of arterial and venous blood are different. Oxygenated (arterial) blood is bright red, while dexoygenated (venous) blood is dark reddish-purple.
Why is my blood bright red?
Why? Human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that's crucial for carrying oxygen through your bloodstream. Heme contains an iron atom which binds to oxygen; it's this molecule that transports oxygen from your lungs to other parts of the body.
What is difference between polycythemia and polycythemia vera?
Polycythemia, also called erythrocytosis, refers to an increase in red blood cell mass, noted on laboratory evaluation as increased hemoglobin and hematocrit levels. Polycythemia vera is a subtype of polycythemia and is associated with the overproduction of all 3 cell lines.
What is the difference between polycythemia and erythrocytosis?
Erythrocytosis is sometimes referred to as polycythemia, but the conditions are slightly different: Erythrocytosis is an increase in RBCs relative to the volume of blood. Polycythemiais an increase in both RBC concentration and hemoglobin, the protein in red blood cells that carries oxygen to the body's tissues.
Can polycythemia cause leg pain?
PV causes blood to be thicker than normal due to high levels of red blood cells and platelets. If you have PV and leg pain, a clot may be the cause. A high red blood cell count makes blood thicker so it flows less efficiently.
How does vitamin B12 cause macrocytic anemia?
Vitamin B12 deficiency is a cause of macrocytosis. Because DNA synthesis requires cyanocobalamin (vitamin B12) as a cofactor, a deficiency of the vitamin leads to decreased DNA synthesis in the erythrocyte, thus resulting in macrocytosis.
What gives blood its bright red color?
RBCs contain hemoglobin (say: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.
What does it mean when your blood is bright red?
The colors of arterial and venous blood are different. Oxygenated (arterial) blood is bright red, while dexoygenated (venous) blood is dark reddish-purple.
What is the healthiest blood type?

What’s the golden blood type?
Rh-null One of the world's rarest blood types is one named Rh-null. This blood type is distinct from Rh negative since it has none of the Rh antigens at all. There are less than 50 people who have this blood type. It is sometimes called “golden blood.”
What’s the difference between bright red blood and dark red blood?
The color of human blood ranges from bright red when oxygenated to a darker red when deoxygenated. It owes its color to hemoglobin, to which oxygen binds.
Why is my blood bright red and watery?
Watery period blood Toward the end of your cycle, your period blood may appear watery and thin. It also may grow darker in color as the blood begins to oxidize. Period blood that's bright red and watery can be fresh blood coming straight from your uterus. This may indicate an injury or a miscarriage.
What shade of red is blood?
brownish-red Blood red is a brownish-red shade with the hex code #880808, often created solely with red in the RGB color model. Blood red includes multiple shades that resemble the color of blood at varying levels of oxygenation–bright red with more O2, rusty with less.
When should you suspect polycythemia vera?
Diagnosis. PV should be suspected when hemoglobin and/or hematocrit levels are elevated (i.e., hemoglobin level greater than 18 g per dL (180 g per L) in white men and 16 g per dL (160 g per L) in blacks and women; hematocrit level greater than 52 percent (0.52) in white men and 47 percent (0.47) in blacks and women).
How do you rule out polycythemia vera?
These tests include a complete blood count (CBC) and other tests, if necessary.
- Complete Blood Count. Often, the first test used to diagnose PV is a CBC. The CBC measures many parts of your blood. …
- Other Blood Tests. Blood smear. …
- Bone Marrow Tests. Bone marrow tests can show whether your bone marrow is healthy.
