What is the main difference between the pulmonary and the systemic circuits of the circulatory ...

1) The pulmonary system involves blood circulation to the lungs, while systemic circulation is concerned with the flow of blood to the rest of the body.

2) a. right common carotid artery;
b. right subclavian artery;
c. right ventricle;
d. dorsal aorta;
e. celiac artery;
f. left renal artery;
g. left external iliac artery; h. right umbilical artery.

3) The respiratory system is designed to take in oxygen which will diffuse into the circulatory system from the lungs, and remove carbon dioxide which will leave the circulatory system and be released to the atmosphere.

4) Tracheathe windpipe, reinforced by cartilaginous rings, which
runs from the glottis to the thoracic cavity where it divides to form the bronchi to the lungs.
The trachea carries oxygen and carbon dioxide between the lungs and the nasal
passages. Esophaguspart of the alimentary canal between the mouth and the
stomach. It is a very muscular organ but has no cartilaginous rings like the trachea.

5) The main
organs for digestion are the stomach and small intestine. Most nutrients are absorbed in
the small intestine.

6) Mouth, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (ascending colon, transverse colon, descending colon, sigmoid colon, rectum), anus.

7) The digestive system includes all of the organs located within the digestive tract in addition to accessory organs that aid in digestion such as the liver and pancreas. The digestive tract includes the mouth, esophagus, stomach, 3 sections of the small intestine and 5 sections of the large intestine.

8) They are ventral to the spinal
cord and the thoracic cavity is superior to the abdominopelvic cavity.

9) Female pigs have a triangular-shaped urogenital papilla anterior to
the anus while male fetal pigs have a penile opening just posterior to the base of the
umbilical cord and a scrotal sac under the tail.

10) In pigs, the first toe or digit id missing on both the
hind and forelimbs. In addition, in pigs the second and fifth digits are reduced in size, and
the middle two digits are flattened. Digitigrade locomotion means walking with the weight
on the tips of the digits. Plantigrade locomotion involves using the entire foot for walking.

Bravo! This is awesome
