A

Mesentery

18
Q

What are the two (2) types of mesenteries?

A

Dorsal Mesentery (attaches from digestive tract to median dorsal line)

Ventral Mesentery (visually lost except in the liver and urinary bladder)

19
Q

Large, trilobed brownish organ occupying the anterior half of the pleuroperitoneal cavity

A

Liver

20
Q

The greenish, spherical sac that stores bile secreted by the liver.

A

Gallbladder

21
Q

What are the ducts that carry bile to the duodenum?

A

Hepatic Ducts (from Liver)
Cystic Ducts (from Gallbladder)
Combined are called the
Common Bile Duct

Sac-like organ with three (3) regions. Found dorsal (behind) from the liver.

A

Stomach

A

Spleen

29
Q

Abrupt angle to the right that connects the stomach to the small intestines.

Q

The large intestine leads into the rectum, which exits via the?

A

CLOACAAAAAA

35
Q

What do you call the exchange of gases?

A

Respiration

36
Q

Two (2) stages of respiration.

A

External Respiration (exchange between environment and organs)

Internal Respiration (exchange within body fluids and tissue cells)

37
Q

Cavity which the glottis opens downward into.

A

Larynx (voicebox)

Cricoid Cartilages (Posterior)

39
Q

Elastic bands found in the larynx.

A

Vocal cords

40
Q

The extremely short tube that connects the larynx to the lungs.
