What is chemotaxis?
The attraction of cells (ex. leukocytes) to chemical stimuli (like foreign invaders)
300
What is the last substance to be produced in the coagulation stage?
Fibrin

What are thrombocytes?
Cell fragments in the blood that help prevent blood loss

How would blood vessels respond to hot weather? Cold?
In hot weather, blood vessels open up so that heat can escape via the skin.
In cold weather, blood vessels constrict to bring blood closer to the deeper, warmer parts of the body.

Give four reasons as to why erythrocytes are the perfect shape for carrying Oxygen.
The flat shape allows for a larger surface area to hold more oxygen.
The center is very thin, which allows for CO2 and O2 to be exchanged rapidly.
The cell can twist and bend trhough tiny blood vessels easily.
Erythrocytes are anucleate, meaning they can generate enough ATP by glycolysis alone

What are the two substances released by basophils? What do they do?
Histamine - promotes inflammation
Heparin - prevents blood from clotting locally

List and explain the three steps of hemostasis.
Vasoconstriction stage - when blood vessels constrict; helps to close down the tear in the blood vessel
Platelet plug stage - damaged vessels cause the platelets to swell and get sticky to each other and the vessel wall. This happens because there is collagen in the exposed vessel wall, which the platelets are exposed to.
Coagulation stage - the blood vessel produces prothrombinase (which makes thrombin). The thrombin converts fibrinogen into fibrin. Fibrin forms long fibers thar are insoluble in water
