In order for oxygen in the inspired air to reach hemoglobin, it must diffuse across all of the following structures, except: one or two smooth muscle cells.
Explanation:
- In the process of oxygen reaching hemoglobin it gets diffused across layer of surfactant, an endothelial cell, type I pneumocyte, and the plasma membrane of the erythrocyte.
- The molecule that is responsible for the carrying of oxygen into the blood cells is protein hemoglobin.
- The normal adult human's blood is the mixture of six different species of hemoglobin molecules. These all molecules consist of same function as well as structure.
The condition in which the placenta is implanted in the lower uterine segment near or over the internal cervical is Placenta previa.

Placenta previa is a condition in which the placenta covers all or part of the opening to the cervical aperture, which sits at the top of the vagina, and lies very low in the uterus. One in 200 pregnancies results in placenta previa.

The syndrome known as placenta increta refers to the placenta's abnormally strong attachment to the uterus and subsequent embedding in the muscle wall of the organ. A disorder known as placenta percreta.
<h3>
