Arteries
Arteries are elastic vessels that transport blood away from the heart. Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells. Systemic arteries deliver blood to the rest of the body.
Veins
Veins are elastic vessels that transport blood to the heart. Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins.
Capillaries
Capillaries are extremely small vessels located within the tissues of the body that transport blood from the arteries to the veins. Fluid and gas exchange between capillaries and body tissues takes place at capillary beds.
Sinusoids
Sinusoids are extremely small vessels located within the liver, spleen, and bone marrow.
Arterioles
a small diameter blood vessel that branches out from an artery to a capillary
During pregnancy, the form of estrogen that predominates is produced by the placenta, and may be useful in prenatal screening is Human chorionic gonadotropin hormone (hCG).
Human chorionic gonadotropin hormone (hCG) hormone is only produced during pregnancy. It is produced predominantly in the placenta. Levels of the hormone hCG, found in the mother's blood and urine, rise greatly during the first month of pregnancy.
hCG can detect the pregnancy ten days after conception. It is the earliest method to check the pregnancy. It also helps to detect the correct age of the fetus and the problems related to the pregnancy like ectopic pregnancies, miscarriages etc.
