Q

What blood cells can leave capillaries and enter interstitial space?

A

leukocytes

17
Q

functions of blood

A

transportation, protection, regulation

18
Q

pulmonary circuit vs systemic circuit

A

pulmonary: lungs
systemic: head and body

19
Q

Formed elements

A

erythrocytes, leukocytes, platelets

20
Q

erythropoesis

A

hemocytoblast > myeloid stem cell > eryethroblast > reticulocyte > erythrocyte

21
Q

what leukocytes are capable of phagocytosis?

A

Neutrophils, eosinophils, monocytes

22
Q

Neutrophils

A

bacteria slayers (WBC)

23
Q

Lymphocytes

A

immunity
Tcells: act directly on virus-infected cells or tumor cells
Bcells: product anitbodies
Natural killer cells: non specific defense

24
Q

Monocytes

A

mature into macrophage, eat bacteria, dead cells and cellular debris

25
Q

Eosinophils

A

attack parasitic worms, lessen severity of allergies

26
Q

Basophils

A

promote inflammation

27
Q

Platelets (thrombocytes)

A

used for clotting, regulated by thrombopoeitin

28
Q

anemia

A

a decrease in the total amount of hemoglobin in the blood (generally less than 13.5 g / dL in males and 12.5 g / dL in females), which results in reduced carrying capacity for oxygen.
