What organ serves as respiratory digestive excretory in fetus?
The placenta is the first organ to be created during mammalian development. As the main link between the mother and the fetus it has more diverse functions than any other organ, serving as a digestive, excretory, respiratory, endocrine, and immune system.
Which of the following functions as the respiratory and excretory organ of the fetus?
The placenta, thus, serves as the nutritive, respiratory and excretory organ of the foetus. The blood of the mother and foetus do not mix at all in the placenta or at any other place.
What organ serves as a respiratory and digestive?
The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.
What do the anterior and posterior tibial veins unite to form?
The two anterior tibial veins ascend in the interosseous membrane between the tibia and fibula and unite with the posterior tibial veins to form the popliteal vein. Like most deep veins in legs, anterior tibial veins are accompanied by the homonym artery, the anterior tibial artery, along its course.
What is fetal blood circulation?
The fetal circulation system is distinctly different from adult circulation. This intricate system allows the fetus to receive oxygenated blood and nutrients from the placenta. It is comprised of the blood vessels in the placenta and the umbilical cord, which contains two umbilical arteries and one umbilical vein.
What is the last organ to develop in a fetus?
Almost all organs are completely formed by about 10 weeks after fertilization (which equals 12 weeks of pregnancy). The exceptions are the brain and spinal cord, which continue to form and develop throughout pregnancy. Most malformations (birth defects) occur during the period when organs are forming.
How does an embryo turn into a fetus?
At the end of the 8th week after fertilization (10 weeks of pregnancy), the embryo is considered a fetus. During this stage, the structures that have already formed grow and develop. The following are markers during pregnancy: By 12 weeks of pregnancy: The fetus fills the entire uterus.
What is the main organ for breathing?
The main organ of the respiratory system is the lungs. Other respiratory organs include the nose, the trachea and the breathing muscles (the diaphragm and the intercostal muscles).
What organ is shared by both the respiratory and digestive system and connects the nose mouth and voice box?
There are three main divisions of the pharynx: the oral pharynx, the nasal pharynx, and the laryngeal pharynx. The latter two are airways, whereas the oral pharynx is shared by both the respiratory and digestive tracts.
Where is the anterior tibial vein ultrasound?
To find the anterior tibial artery (ATA) and the tibioperoneal trunk (TPT), keep moving the probe down the patient’s leg. The distal popliteal artery can be seen as it bifurcates into the ATA and TPT, with the popliteal vein above the artery.
What does the tibial veins supply?
In human anatomy, there are two anterior tibial veins. They originate and receive blood from the dorsal venous arch, on the back of the foot and empties into the popliteal vein. The anterior tibial veins drain the ankle joint, knee joint, tibiofibular joint, and the anterior portion of the lower leg.
Which organ is by passed in Foetal circulation?
Fetal circulation bypasses the lungs via a shunt known as the ductus arteriosus; the liver is also bypassed via the ductus venosus and blood can travel from the right atrium to the left atrium via the foramen ovale.
