A large increase in fetal growth occurs during the third trimester of pregnancy. This is when the baby gains the most weight and develops important organs and systems. The rapid growth during this period is crucial for the baby's overall health and development.
A significant increase in fetal growth typically occurs during the third trimester of pregnancy, particularly in the final weeks. This period is characterized by rapid weight gain and organ maturation as the fetus prepares for birth. The growth is driven by increased nutrient supply and hormonal changes that support development.
proteins made by genes that are very active during fetal development but function at a very low level after birth. The genes become activated when a malignant tumor arises and produce large amounts of protein
A condition in which one or more lobes of the lungs become fluid-filled sacs (cysts). Large CCAMs may prevent lung development, cause heart failure, or prevent the ingestion of amniotic fluid.
The alimentary canal of fetal pigs consists of the mouth, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (cecum, colon, rectum), and anus. These structures play a role in the digestion and absorption of nutrients, with some modifications present in fetal pigs compared to adult pigs for fetal development and nutrient absorption during early stages of life.
The arterial ligament in adults was once the arterial duct (ductus arteriosus) in the fetus. This is a connection between the pulmonary trunk, the large vessel leaving the right side of the heart that in an adult would be conducting deoxygenated blood to the lungs for some oxygen, and the aorta, the large vessel leaving the heart with the oxygenated blood for the rest of the body. Along with the ductus venosus, moving oxygenated blood from the mother/placenta directly to the large vein feeding the heart, and the foramen ovale connecting the two atria inside the heart, fetal blood flow from the heart mostly bypasses the lungs and goes right into general circulation. The primary reason for this is that the lungs are not being used to collect oxygen from the environment, as the placenta is exchanging oxygen from the mother's blood to the fetal blood.
A Pinard horn is a simple, curved device used in obstetrics to amplify fetal heart sounds during pregnancy. It consists of a long, funnel-shaped tube that directs sound waves from the mother's abdomen to the listener's ear. The practitioner places the large end of the horn on the mother's belly and listens through the smaller end, allowing them to hear the fetal heartbeat more clearly. This tool is particularly useful in settings where electronic fetal monitors are unavailable.
Yes, the placenta is a large, disc-shaped organ that forms during pregnancy, attaching to the wall of the uterus. It facilitates the exchange of nutrients, gases, and waste products between the mother and the developing fetus. The placenta also produces hormones that support pregnancy and fetal development.
If you look at the back wall of a fetal pig heart, you will see a vessel that is large in size in a sheep compared to the small size of the fetal pig heart. In sheep, the hemiazygous vein develops a connection to the heart through what becomes the superior vena cava.
The function of the liver is the remove toxins and metabolic wastes from the body. Fetal pigs have large livers because this function is important early on in life.

The thymus gland is in the upper thorax anterior to the heart.
