Flashcards on digestive system, kidney function, and reproductive anatomy.

What is the muscular organ where most mechanical digestion occurs?

Stomach

What tissue is found lining the stomach, and what is its function?

Simple columnar epithelium with gastric glands

You observe goblet cells under a microscope. Which organ is it likely from?

Large intestine (or small intestine)

What is the main function of the renal cortex?

Filtration of blood

Which organ stores urine before it’s released?

Urinary bladder

What part of the nephron is responsible for filtering blood?

Glomerulus (within the renal corpuscle)

What does the presence of nitrites in urine suggest?

Urinary Tract Infection (UTI)

If protein is present in urine, what might be damaged?

Glomerular filtration barrier (in the glomerulus)

What is the path of sperm from the testes to the urethra?

1. Testes (sperm production) 2. Epididymis (sperm storage/mat

What is the function of the liver in digestion?

Produces bile for fat emulsification.

What is the function of the gallbladder?

Stores and concentrates bile.

Where does most nutrient absorption occur?

Small intestine.

What epithelium lines the esophagus?

Stratified squamous epithelium.

What epithelium lines the stomach and intestines?

Simple columnar epithelium.

How do you distinguish the large intestine histologically?

No villi, many goblet cells for mucus secretion.

What process occurs in the renal cortex?

Filtration of blood in the glomeruli.

What structure collects urine in the kidney?

Renal pelvis.

What is the function of the nephron loop (loop of Henle)?

Concentrates urine by reabsorbing water and salt.

What is the path of urine flow starting from nephron?

Collecting duct → renal papilla → minor calyx → major calyx → renal pelvis → ureter.

What is the function of the ureter?

Transports urine from kidney to bladder.

What is the function of the urinary bladder?

Stores urine.

Which gender has a longer urethra?

Males.

What structure filters blood in the nephron?

Glomerulus.

Glucose in urine may indicate what?

Diabetes mellitus.

What does dark yellow urine with high specific gravity suggest?

Dehydration.

What are normal urine characteristics?

Yellow, clear, slightly acidic.

What happens during Prophase I?

Homologous chromosomes pair up and crossing over occurs.

How many daughter cells result from meiosis?

4 haploid cells.

Are meiosis daughter cells genetically identical?

No.

What is the function of the epididymis?

Stores and matures sperm.

What is the function of the uterine tube (fallopian tube)?

Site of fertilization, transports egg to uterus.

What hormone does the corpus luteum secrete?

Progesterone.
