Umbilical Arteries
Umbilical Arteries

Specialized arterial vessels in the umbilical cord. They carry waste and deoxygenated blood from the FETUS to the mother via the PLACENTA. In humans, there are usually two umbilical arteries but sometimes one.

Umbilical Veins
Umbilical Veins

Venous vessels in the umbilical cord. They carry oxygenated, nutrient-rich blood from the mother to the FETUS via the PLACENTA. In humans, there is normally one umbilical vein.

Fetal Heart
Fetal Heart

The heart of the fetus of any viviparous animal. It refers to the heart in the postembryonic period and is differentiated from the embryonic heart (HEART/embryology) only on the basis of time.

Ductus Arteriosus
Ductus Arteriosus

A fetal blood vessel connecting the pulmonary artery with the descending aorta.

Truncus Arteriosus
Truncus Arteriosus

The arterial trunk arising from the fetal heart. During development, it divides into AORTA and the PULMONARY ARTERY.

Endocardial Cushions
Endocardial Cushions

A fetal heart structure that is the bulging areas in the cardiac septum between the HEART ATRIA and the HEART VENTRICLES. During development, growth and fusion of endocardial cushions at midline forms the two atrioventricular canals, the sites for future TRICUSPID VALVE and BICUSPID VALVE.

Vernix Caseosa
Vernix Caseosa

An unctuous substance composed of sebum and desquamated epithelial cells, which covers the skin of the fetus.

Fetal Blood
Fetal Blood

Blood of the fetus. Exchange of nutrients and waste between the fetal and maternal blood occurs via the PLACENTA. The cord blood is blood contained in the umbilical vessels (UMBILICAL CORD) at the time of delivery.

Meconium
Meconium

The thick green-to-black mucilaginous material found in the intestines of a full-term fetus. It consists of secretions of the INTESTINAL GLANDS; BILE PIGMENTS; FATTY ACIDS; AMNIOTIC FLUID; and intrauterine debris. It constitutes the first stools passed by a newborn.

Fetus
Fetus

The unborn young of a viviparous mammal, in the postembryonic period, after the major structures have been outlined. In humans, the unborn young from the end of the eighth week after CONCEPTION until BIRTH, as distinguished from the earlier EMBRYO, MAMMALIAN.

Aborted Fetus
Aborted Fetus

A mammalian fetus expelled by INDUCED ABORTION or SPONTANEOUS ABORTION. Abortion, Induced; Abortion, Spontaneous;

Umbilical Cord
Umbilical Cord

The flexible rope-like structure that connects a developing FETUS to the PLACENTA in mammals. The cord contains blood vessels which carry oxygen and nutrients from the mother to the fetus and waste products away from the fetus.
