Blood Physiology and Cellular Components Quiz

Red blood cells contain hemoglobin, which binds to oxygen for transport throughout the body.

Blood plasma is primarily composed of water, along with various proteins, electrolytes, and hormones.

Hemoglobin binds to oxygen in the lungs and releases it to tissues, while also transporting carbon dioxide back to the lungs.

Blood type AB can receive transfusions from all other blood types, as it lacks antibodies against ABO antigens.

Hematocrit is a measure of the proportion of blood that is made up of red blood cells, typically expressed as a percentage.

White blood cells protect the body from infections and foreign invaders by mounting immune responses.

Neutrophils are a type of white blood cell characterized by the presence of granules in their cytoplasm.

Erythropoietin, produced by the kidneys, stimulates the production of red blood cells in bone marrow.

Red blood cells typically live for about 120 days before being removed by the spleen and liver.

Hematopoiesis is the process by which blood cells are formed in the bone marrow.

Platelets play a crucial role in the clotting process, forming clots to prevent excessive bleeding.

Blood type O lacks A and B antigens, making it compatible with all other blood types during transfusions.

The spleen filters the blood, removing old or damaged red blood cells from circulation.

The pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.

Eosinophils are involved in allergic reactions and parasitic infections, releasing toxins to combat these invaders.
