Q

Describe how food moves from your mouth to the duodenum

A

food goes through the pharynx, through the esophagus, through the cardiac sphincter valve into the stomach. The food is churned up then moves out of the pyloric sphincter valve to the duodenum

Q

from the small intestine, how does undigested food travel to the anus

A

from the duodenum, food travels to the ileum and undigested food moves into either the cecum (to digest plant food) or out of the rectum to the anus. The large intestine sucks water out.

A

Cavity located under the thoracic cavity including the digestive system and spleen

55
Q

where are the Urinary and reproductive systems found?

thin membrane covering the heart, easily pulled off

57
Q

the left and right atria (1 atrium)

A

purplish grey organs on either side of the heart (it helps to pump blood to the ventricle)

58
Q

pulmonary trunk

A

tube shaped trunk coming out of the top of the top of the heart, intersects with the Aorta
- used for blood transportation

59
Q

Aorta and Dorsal Aorta

A

Vessel that supplies body with blood, dorsal aorta supplies lower body with blood and curves down to the abdominal cavity.

The upper aorta branches into right brachiocephalic and left subclavian

60
Q

Right Brachiocephalic

A

Branches off the Aorta, it helps to supply most of the upper body with blood and branches into common cartriod and right subclavian

Q

common cartroid and left/right cartroids

A

The common cartroid is a branch of the right brachiocephalic, it branches into the right and left cartoids that supply blood to head and neck.
