Final Practical Microscopes

Ovary

- ALL of da follicles

Fallopian Tube

Fallopian Tube

- ampulla & isthmus

- fimbriae

Ovary:

- endometrium breaking down

Ovary

- Endometrium (2nd week)

Ovary

- Endometrium (3rd week)

Ovary

- follicle (most mature one)

Epididymus (of the testes)

- ZOOMED

- pseudostratified columnar

- reticular fibers

Epididymus (of the testes)

- pseudostratified columnar

- reticular fibers

Testes

- seminiferous tubule

Testes

- seminiferous tubule (ZOOMED)

- makes sperm w spermatogenesis

- makes spermatoli cells

ovary

- corpus luteum

- follicles

Kidney 400x (renal corpuscle)

Kidney

- cortex

Kidney

- ZOOMED

- convoluted lobules

- loops of henle

Kidney

- Medulla

- collecting ducts

Kidney

- renal corpuscle

- glomerulosa

- surrounded by bomans capsule

Ureter: Kidney to Bladder

- folded lumen

- stratified cuboidal

Urethra (female)

- stratified columnar

Bladder

- transitional

Lung

- alveoli

- simple squamous (line)

Lung

- Alveoli (Respiratory Tree)

Trachea

- Hyaline cartilage

Esophagus

- cardia

Esophagus

- skeletal muscle

Esophagous

- stratified squamous epithelial tissue

- skeletal --> smooth muscle

Stomach junction

- stratified squamous --> simple columnar

- smooth muscle

Stomach

- smooth muscle

- gastric pits (blue circle)

Cells in da gastric pits:

- mucus neck cells

- parietal cells --> HCl acid

- chief cells --> pepsinogen

Gastric pits (Stomach)

- mucus neck cells

- parietal cells (hydrochloric acid - HCl)

- chief cells (pepsinogen)

- simple columnar

Duodenum - Small Intestine (SI)

Mucosal Layer - villus, simple columnar cells

- capillary beds r in da middle of villus

* cells tht lines edge of villi --> cells tht absorb nutrient & take it to da blood stream

*pointer is on the villi

Ileum (of da SI)

- pyers patch

- lymphatic tissue (ring around it)

Colon (LI)

- goblet cells (produces mucus to ⬇️ friction)

- crypts (inward folds) - simple columnar

- absorbs H2O

most superficial

- mucosa

- submucosa

- muscularis

- serosa

Layers of the GI Tract

- longitudinal

- circular

- oblique

Layers of the Stomach
