Study Notes

Overview of Blood and Clotting

Blood transports oxygen and nutrients to tissues
Blood removes waste products from tissues
Blood functions include red blood cells, white blood cells, platelets, coagulation proteins, complement proteins, and kinin proteins
The cardiovascular system circulates blood

Red Blood Cells

Red blood cells (RBCs) carry oxygen to the tissues
RBCs remove carbon dioxide (CO2) from the tissues
In adults, the normal range of hemoglobin in women is 11–16 g/dL.
In adults, the normal range of hemoglobin in men is 14–18 g/dL.
Anemia is a condition where hemoglobin levels are lower than normal.
Normal red blood cells have a biconcave disk shape for optimal gas exchange
RBCs are 7 to 8 µm in diameter and 2 µm thick
RBCs can be deformed which allows them to fit through narrower capillaries
