The endometrium is a specialised layer able to receive a blastocyst and with it form a placenta to support a growing foetus. The myometrium is a thick smooth muscle layer able to stretch to match the growth of the developing foetus and then expel it at birth. The perimetrium is a thin covering to the uterus that is largely peritoneum. The cervix is the entrance to the body of the uterus and the uterine tubes connect to the ovaries.

2025-09-1905 minDissectible Me 5 minute anatomyFoetal heart adaptationsThe foetus gets its oxygen from the placenta and not from the lungs when in the uterus. The lungs are still growing and little blood flows through them. The foramen ovale is a flap valve that lets blood pass from the right atrium directly into the left atrium, avoiding the lungs. From the left side of the heart this blood will flow into the aorta and off around the body. The ductus arteriosus is a vessel that allows blood to flow from the pulmonary trunk through and into the aorta, again avoiding going through the lungs. At birth both...

At rest you're just using your diaphragm and the elastic recoil of the lungs themselves, when you're a little more active and running around the intercostal muscles start to move the ribs, and when you really need to pull air in and push it out you can take advantage of accessory muscles of respiration that might not normally move the ribs.
