The major organs of the respiratory system in a fetal pig include the lungs, trachea, bronchi, and bronchioles. The lungs are the primary organs responsible for gas exchange, while the trachea, bronchi, and bronchioles help to deliver air to and from the lungs.
The major salivary glands are located around the lower maxilla in both humans and fetal pigs. These are used to generate saliva.NEWThe major salivary glands are the parotid, submandibular, and sublingual glands. They secrete saliva into your mouth; the parotid through tubes that drain saliva, called salivary ducts, near your upper teeth, submandibular under your tongue, and the sublingual through many ducts in the floor of your mouth.
There are three major differences between normal circulatory pathways and fetal circulation. First, as you have already learned, oxygenated blood that is high in nutrients obtained from the placenta enters the fetal pig body not from lung capillaries, but via the umbilical vein to the ductus venosus in the liver. The ductus venosus leads in turn to the caudal vena cava, through which the blood enters the right atrium. The second major difference is the presence in fetal pigs of an opening between the heart atria (through the interatrial septum), called the foramen ovale. Oxygenated blood entering the right atrium from the caudal vena cava tends to pass through the foramen ovale into the left atrium, thus bypassing the pulmonary circulation system. Deoxygenated blood from the cranial vena cava enters the atrium anteriorly and flows into the right ventricle. As a result of this arrangement, there is little mixing of oxygenated and deoxygenated blood. A third major difference is the action of the ductus arteriosus vessel, which shunts blood away from the fetal pig's lungs and into the aorta. Highly oxygenated blood in the left atrium is pumped into the left ventricle and then into the aorta. It then enters the coronary arteries and the arteries of the head region, before mixing with deoxygenated blood from the ductus arteriosus and the lower systemic circulation.
Fetal pigs are unborn pigs often used in biology classes as objects for dissection. It belongs to the animal kingdom, the order Artiodactyla, genus Sus, class of mammals, and the species Domestica.
biologist classify worms into three major phyla-flatworms roundworms and segmented wormsYes, that is true, but those are not characteristics! Some of their characteristics are:-A knot of nerve tissue-Sense organs-Sexual reproduction-Bilateral symmetry-Obtaining food by sucking their hostsGood luck!!!! I know science can be challenging at times!!!!!! :D
When all major body parts are flexed it is the fetal position.
Poriferans (sponges) lack many common characteristics of animals such as a head or a mouth. Typically poriferans do not have eyes, ears, as well as other sense organs. Poriferans do not possess major organs such as heart, stomach, muscles, or even a nervous system.
