Question

1. Name the epithelium found in the urinary system organs and state it’s function.
2. Name the subdivisions of the small and large intestines in the complete and correct sequence
3. List all alimentary canal organs from oral cavity to anal canal in correct/complete sequence (including the subdivisions of small and large intestine).
4. Locate/ID the anatomy of the urinary bladder and the gross anatomy of the kidney

Answer 1

1. Transitional epithelium found in the urinary system organs. They can contract and expand to distendthe organs .

2. Small intestine consists of duodenum, jejunum and ileum .large intestine, beginning from caecum, vermiform appendix, ascending,transverse, descending and sigmoid colons and ending with the rectum and anal canal.

3.Mouth - teeth , salivary glands , tongue.   
   Pharynx - oropharynx , laryngo pharynx.
   Esophagus.   
   Stomach.   
   Small intestine-duodenum, jejunum and ileum.   
   Large intestine -caecum, vermiform appendix, ascending,transverse, descending and sigmoid colons and ending with the rectum and anal canal.

4. Kidney.   
Location
The kidneys occupy the epigastric, hypochondriac,
lumbar and umbilical regions . Vertically they
extend from the upper border of twelfth thoracic
vertebra to the centre of the body of third lumbar
vertebra. The right kidney is slightly lower than the
left, and the left kidney is a little nearer to the median
plane than the right.
The transpyloric plane passes through the upper part
of the hilus of the right kidney, and through the lower
part of the hilus of the left kidney.   
  ANATOMY The kidneys are bean-shaped paired organs, each weighing about 150 gm in the adult male and about 135 gm in the adult female. The hilum of the kidney is situated at the midpoint on the medial aspect where the artery, vein, lymphatics and ureter are located. The kidney is surrounded by a thin fibrous capsule which is adherent at the hilum.
Cut surface of the kidney shows 3 main structures: well- demarcated peripheral cortex, inner medulla and the innermost renal pelvis .   

Urinary bladder.
It lies extraperitoneally and the peri- toneum is reflected on its superior surface. Besides superior surface (or dome), the bladder has posterior surface (or base) and two lateral surfaces. The trigone is at the base of the bladder and continues as bladder neck. Normally, the capacity of bladder is about 400 to 500 ml without over-distension. Micturition is partly a reflex and partly a voluntary act under the control of sympathetic and parasympathetic innervation.
