Electrolytes, nutrients, gases and wastes make up ______ of plasma by weight. - ANSW✔️less than 1%
The cells in the organs that remove old and/or damaged erythrocytes are - ANSW✔️macrophages
Which of the following poses the greatest risk for severe illness and even death of an unborn fetus? -
ANSW✔️Second pregnancy, Rh- mother with second Rh+ fetus
In which portion of a sample of whole blood will you find the antigens that determine an individual's
ABO blood type? - ANSW✔️Erythrocytes
How do leukocytes and erythrocytes differ? - ANSW✔️Leukocytes defend the body against pathogens,
