Answer 1

• The QRS complex masks it.

Question 2

The amount of blood ejected by a ventricle during a single beat is called the

Answer 2

stroke volume.

Question 3

Fibrous capsule

Answer 3

Lymph node is enclosed by fibrous capsule

Question 4

trabeculae

Answer 4

divide the lymph node into compartments.

Question 5

reticular fibers

Answer 5

support the cellular components.

Question 6

Answer 6

outer region of the lymph node

Question 7

germinal
centers

Answer 7

Masses of cells

Question 8

medullary cords

Answer 8

Cells are arranged

Question 9

lymphoid nodules,
also known as Peyer’s Patches.

Answer 9

The lymphoid nodule is a compact mass of lymphoid cells that appears as a large collection of purple circles.

Question 10

Neutrophils

Answer 10

This cell is a granulocyte with a nucleus that typically has between 3 – 5 lobes

Question 11

Eosinophils

Answer 11

This cell is also granulocyte, look for a nucleus that is typically bilobed and a
distinctive pink cytoplasm

Question 12

Basophils

Answer 12

The third granulocyte, this cell will appear dark purple and their bilobed nucleus
may be difficult to see due to the dark staining granules

Question 13

Lymphocytes

Answer 13

This cell is an agranulocyte and typically has a spherical nucleus. They will be
just slightly larger than the erythrocytes

Question 14

Monocytes

Answer 14

This cell is also an agranulocyte, it will be a very large cell, larger that the
erythrocytes and other leukocytes. It typically has a C-shaped nucleus

Answer 18

Antigens on erythrocyte surface that determine blood type

Question 19

Agglutinins

Answer 19

Antibodies that may be present in the plasma
