skeletal system
none of the above
integumentary system
lymphatic system
all the above

28 multiple choice 2 points
what is the major cell type of the lymphatic system?
erythrocytes
osteocytes
lymphocytes
epithelial

29 multiple choice 2 points
which layer of the internal kidney contains 85% of nephrons?
renal cortex
renal fascia
renal medulla
renal pelvis

Explanation:

Identify organ systems of the human body

The 11 organ systems of the human body include the skeletal, integumentary, and lymphatic systems. Since all three listed options are valid organ systems, "All the above" is the correct choice.

Determine the major cell type of the lymphatic system

The lymphatic system is primarily composed of lymphocytes (T cells, B cells, and natural killer cells), which are specialized white blood cells. Erythrocytes are red blood cells, osteocytes are bone cells, and epithelial cells line surfaces.

Locate the kidney layer containing 85% of nephrons

Approximately 85% of nephrons are cortical nephrons, which are located almost entirely within the renal cortex. The remaining 15% are juxtamedullary nephrons that extend deep into the renal medulla.
