The blood vessel that takes blood to the digestive organs and lower body is the abdominal aorta. It branches into several arteries, including the mesenteric arteries, which supply the intestines, and the common iliac arteries, which supply the lower body. This system ensures that the lower parts of the body and digestive organs receive the necessary oxygenated blood for their functions.
Inferior vena cava.
The descending aorta is the major blood vessel that supplies blood to the caudal half of a pig.
The lack of nutrients inside a cell compared to the blood vessel creates a concentration gradient between the blood vessel and the cell. Due to the lower concentration in the cell, the nutrients diffuse through the blood vessel wall and into the cell.
Kidney
All 3 types of blood vessels are present, Veins, Arteries, And Capillaries
There are a number of organs involved in excretion: the lower digestive tract including the colon, the kidneys, the lungs, and the sweat glands. The lower digestive tract removes or excretes indigestible items from the digestive tract. The kidneys remove urea which is a product of the breakdown of proteins. The lungs remove carbon dioxide which is also a waste product. And the sweat glands remove excess water.
Inferior vena cava
Inferior Vena Cava, collects blood from the lower extremities and runs up along side the abdominal aorta and into the heart.
There are two, the Superior Vena Cava that brings blood from the head, and the Inferior Vena Cava that brings blood from the lower body.
Arteries have a pulse due to the rhythmic contraction of the heart, which creates a pressure wave that can be felt as the pulse in arteries. Veins do not have a pulse as they carry blood back to the heart at a lower pressure.
In the lower abdomen, the intraperitoneal organs include the sigmoid colon and the rectum. Additionally, parts of the small intestine, specifically the ileum and jejunum, are also located in this region. The spleen is not in the lower abdomen, but the liver and stomach, which are primarily located in the upper abdomen, can also impact the lower abdominal organs due to their proximity. Overall, the lower abdominal intraperitoneal structures are primarily associated with the digestive system.
