How can you differentiate a monocyte and a lymphcyte?

A monocyte is bigger and a lymphocyte is smaller

How does the size of a platelet compare to a RBC?

A platelet is smaller

Where is a megokarocyte going to be found?

Bone marrow

Where is the endomysium vs the perimysium?

The endomysium is in between the cells, the perimyosium is at the edges

What animal has nucleated erythrocytes?

What is the intercalated disc?

A dark line in the cardiac muscle (heart)

Erythrocyte

central pallor
