The waste products and the CO₂ are sent through the umbilical cord and then the placenta, to finally go to the mother’s circulation and is then eliminated.

To determine the sex, it is necessary to locate the urogenital opening. For female fetal pigs, it is located near the anus, whereas it is near the umbilical cord in males. Also, for females, there is a urogenital papilla near the opening that is not present in males. A male pig will also have a scrotum.

3. What is another name for the "belly " region of the pig?
The abdomen

From the nasal cavities

The main function of the epiglottis is to seal off the esophagus when eating so that food does not get inhaled. 

Saliva is secreted by salivary glands in the oral cavity. It contains mucus that makes the food moister and also buffers its pH. It also contains an enzyme called salivary amylase that begins the process of breaking down starches. There is another enzyme called lipase that is present in saliva and that breaks down triglycerides.  

The placenta. 

It carries bile, from the gallbladder to the duodenum. 

They travel from the pancreas through ducts, and empty the enzymes in the duodenum, where they come in contact with food.

3.    Ureter: Carries urine from kidney to bladder. 

4.    Urinary bladder: Storage of urine. 

5.    Renal artery: Carries blood to the kidney. 

6.    Renal vein: Carries blood out of the kidney. 

7.    Renal cortex: Where there is reabsorption of nutrients needed by the body such as water, Na+, etc. and filtration of blood in the glomerulus.
8.   Renal medulla: Where there is reabsorption of nutrients and secretion of excess ions. 

2.    Testes: Produces sperm cells. 

3.    Epididymis: Stores and transports sperm from testes to vas deferens. 

4.    Vas deferens: Transports sperm to the urethra. 

5.    Urethra: Allows for ejaculation of sperm. 

6.    Inguinal canal: Contains testes until they descend into the scrotal sac. 

7.    Urogenital opening: Allows waste to be expelled out of the body. 

8.    Gubernaculum:          Pulls testes down in the scrotum.

9.    Bulbourethral gland: Contributes to production of semen.

10. Penis: Allows urine and semen to leave the body.
