This closes shortly after birthI. Proximal – located close to the sagittal line of the body.
Fetal circulation is different from adult circulation.
Circulatory system of fetal pig. The circulation of blood in pig fetus is somewhat different. The pig fetus receives oxygen-rich blood from the placenta through the umbilical vein. The umbilical vein reaches the liver from where the blood enters the posterior vena cava through the passage ductus venosus.
Posterior vena cava carries blood to the heart. The circulatory system of a fetal pig is different fromthat of an adult pig because there is a shunt between the wall of the right and left atrium which wouldallow blood to pass directly from the right atrium to the left. This closes shortly after birthI.
Receives deoxygenated blood from the right atrium via the tricuspid valve and pumps it into the pulmonary artery via the pulmonary valve and pulmonary trunk. Right atrium to near the apex of the heart. Fetal circulation is different from adult circulation.
In the fetus blood doesnt get oxygenated in the lungs. It gets oxygenated at the placenta. The umbilical arteries carry blood from the fetus to the placenta.
The umbilical vein carries blood from the placenta back to the fetus. Air and food pass through the oropharynx a space in the posterior portion of the mouth. Below the oropharynx the laryngopharynx leads to the opening of the larynx and esophagus.
From the laryngopharynx air passes through the glottis to the trachea. Hard palate soft palate glottis epiglottis tongue. Fetal pig circulatory system.
Spleen lymphatic system what are the primary functions of the c. Pumps blood throughout the pig. Sac surrounding the heart that is filled with fluid that acts.
Long flat organ which is deep to the stomach. It stores and r. Cranial – toward the head.
Rostral – toward the nosebeak. Caudal – toward the tail. Separated by the transverse plane.
Medial directed towardthe midline sagittal plane Lateral – directed awayfrom the midline sagittal plane Sagittal Plane. Proximal – located close to the sagittal line of the body. The circulatory system consists of the heart which is a four chamber suction and pressure pump that moves blood through two separate systems one to and from the lungs and the other around the body.
The blood returns to the heart from the body through a series of veins which terminate in two large veins called the anterior and posterior vena cava. However this relatively well-oxygenated blood mixes with deoxygenated fetal blood before it enters fetal arterial circulation. The first site of mixing is within the liver.
The umbilical vein enters the liver and its sinusoids but as a result of the increasing blood volume as the fetus develops essentially clears a path through the liver tissue. This page can direct you to the various organs and landmarks in the circulatory system. The circulatory system also called the cardiovascular system in mammals of the pig is responsible for the transportation of nutrients gases wastes and hormones.
Additionally it is involved with the control of body temperature provides channels for the immune system to protect the body and participates in the maintenance of body fluid homeostasis. The circulatory system of the pig functions to transport nutrients gases wastes and hormones. Also the system of both is involved in the regulation of internal temperature provides paths for the immune system to protect the body and participates in the maintenance of body fluid.

The liver is the largest organ of the abdominal cavity one of its many functions is to secrete bile which helps carry away waste and break down fats in the small intestine. Obtain a fetal pig and identify the structures listed in the first photograph. The diagrams below summarize the circulatory system of a mammal.
The drawing below shows some of the major arteries that carry blood to the body. Blood vessels that branch from the aorta carry blood to most of the body.

Locate the organs of the digestive system in a fetal pig. The thyroid gland is a small reddish structure lying over the trachea more anteriorly in your pig. The thyroid gland is the source of thyroid hormones thyroxin and triiodothyronine and is a key endocrine gland regulating metabolism among other things.
