Within the tissues, arterioles terminate into a network of microscopic capillaries. Substances move in and out of the capillary walls as the blood exchanges materials with the cells. Before leaving the tissues, capillaries unite into venules, which merge to form larger and larger veins that eventually return blood to the heart. Of all the blood vessels, only capillaries have walls thin enough to allow the exchange of materials between cells and the blood. Their extensive branching provides a sufficient surface area to pick up and deliver substances to all cells in the body.

Males have an x chromosome and a y chromosome, so if the father gives the child an x chromosome, the child will be female. If the father gives the child a y chromosome, the child will be male. So, chromosomes from the father control whether the child is male or female.
