Apart from the man putting his penis into the woman's vagina, the sex organs can be used in other ways in sexual intercourse. The man and woman can rub each other's sex organs with their hands. They can use sex toys such as dildos or vibrators . They can also engage in oral sex . When a person uses his or her mouth, lips and tongue to touch a woman's clitoris and vulva, this is called cunnilingus . When a person uses his or her mouth, lips, and/or tongue to touch a man's penis, this is called fellatio. A man or a woman (using an strap-on dildo or harness) can also put the sexual organ into a person's anus , this is called anal sex .

The ability to generate patient-specific cells through induced pluripotent stem cell (iPSC) technology has encouraged development of three-dimensional extracellular matrix (ECM) scaffolds as bioactive substrates for cell differentiation with the long-range goal of bioengineering organs for transplantation. Perfusion decellularization uses the vasculature to remove resident cells, leaving an intact ECM template wherein new cells grow; however, a rigorous evaluative framework assessing ECM structural and biochemical quality is lacking. To address this, we developed histologic scoring systems to quantify fundamental characteristics of decellularized rodent kidneys: ECM structure (tubules, vessels, glomeruli) and cell removal. We also assessed growth factor retention--indicating matrix biofunctionality. These scoring systems evaluated three strategies developed to decellularize kidneys (1% Triton X-100, 1% Triton X-100/% sodium dodecyl sulfate (SDS) and % Trypsin-% EGTA/1% Triton X-100). Triton and Triton/SDS preserved renal microarchitecture and retained matrix-bound basic fibroblast growth factor and vascular endothelial growth factor. Trypsin caused structural deterioration and growth factor loss. Triton/SDS-decellularized scaffolds maintained 3 h of leak-free blood flow in a rodent transplantation model and supported repopulation with human iPSC-derived endothelial cells and tubular epithelial cells ex vivo. Taken together, we identify an optimal Triton/SDS-based decellularization strategy that produces a biomatrix that may ultimately serve as a rodent model for kidney bioengineering.

During the Romantic period, the organ became more symphonic, capable of creating a gradual crescendo. New technologies and the work of organ builders such as Eberhard Friedrich Walcker , Aristide Cavaillé-Coll , and Henry Willis made it possible to build larger organs with more stops, more variation in sound and timbre, and more divisions. [33] Enclosed divisions became common, and registration aids were developed to make it easier for the organist to manage the great number of stops. The desire for louder, grander organs required that the stops be voiced on a higher wind pressure than before. As a result, a greater force was required to overcome the wind pressure and depress the keys. To solve this problem, Cavaillé-Coll configured the English " Barker lever " to assist in operating the key action. [35]
