Answer 1

false. they respire anaerobically via glycolysis

Question 2

Compare the life span of different blood corpuscles

Answer 2

RBC’s live the longest of 120 days, that is, 3 months whereas platelets and WBCs have barely a week.

Question 3

Describe Most abundant WBC (structure and function, percentage). It’s similar to? Stain how?

Answer 3

Neutrophils, aka PMNL (poly morpho nuclear leucocytes) since they have a multilobed nucleus.
They are phagocytic (each division has at least one phagocytic cell: PMNL from granulotcytes and Monocytes from agranulocytes: both are phagocytic)
Stain weakly with both acidic and basic dyes.

Question 17

What’s another name for stratum germinatum?

Answer 17

STRATUM MALPIGHI

These cells are columnar and multiply to push more cells into superficial layers.

Question 18

Transitional ep is found in? Important property and Working?

Answer 18

Stretchability. Upon stretching, cells of this epithelium turn flat and increase the volume of the organ. (Lacks both basement membrane and germinative layer)

Found in: renal pelvis, ureter, urinary bladder

IMPORTANT: Non ciliated pseudostratified columnar cells (SIMPLE) line the male urethra.

*note: renal pelvis- Towards the centre of the inner concave surface of the kidney is a notch called Jilin through which the ureter, blood vessels and nerves enter. Inner to the hilum is a broad funnel shaped space called the renal pelvis with projections called calyces.
