INFO:

S e x u a l desire or attraction is triggered by various stimuli, such as visual, auditory, emotional, tactile (touch), fantasies, thoughts, or memory cues. When these stimuli are received, the body begins to respond and cause physiological changes in the body. In response to the stimuli, the brain releases neurotransmitters like dopamine and nitric oxide. These chemicals act as messengers that help to dilate the blood vessels in the pelvic region, including those in the penis. The dilation of blood vessels allows more blood to flow into the penile tissues. The penis has three cylindrical chambers made up of a sponge-like material. When these chambers fill with blood, the penis becomes rigid and erect. At this stage, the male body is prepared for sexual activity. Nerve endings become more sensitive, and touch or friction is met with heightened sensation. To maintain the erection, the veins that usually allow blood to flow out of the penis become compressed. This helps to keep the blood in the penile chambers, sustaining the erection. As s e x u a l activity or stimulation continues, tension builds within the pelvic region. 3dmedicalanimation copyrighted_by_Dandelion _Team The Female Body and Biology | Biology of Female https://youtu.be/WDetHC86Dgo Hemorrhoids|different types of hemorrhoids https://youtu.be/8M7IXJBmIpI Virginity and hymen https://youtu.be/P_17PQFpIAY Fertilization medical animation https://youtu.be/u0y2Wvc0Jm0 we all won this race! https://youtu.be/VYWuySwoqUg What role does sperm structure play in fertilization? https://youtu.be/1YxA6zIvIWw ovulation and menstrual cycle, often called period https://youtu.be/42WIByexiXc The effect of Tied umbilical cord in twins https://youtu.be/vB9ZBnwTfKg High Blood Pressure Hypertension https://youtu.be/gsczOAeGst4 How your body turns food into poo Human digestion system in human beings https://youtu.be/HXrl37BC3QU food digestion is the story of how your food ends up as a poo 3d medical animation dandelion team https://youtu.be/TPdQKcFuhPI coronary angiogram Micro Needle|3d medical animation|sample use only https://youtu.be/sRGMJhit4h0 heart valve replacement 3d medical animation|sample use only|dandelion team https://youtu.be/9L9i59eY5Zg short videos how long does it take for the body to digest food? https://youtu.be/z6G2L1hY5hc The world of inside a bone https://youtu.be/SWCLK4t0iXo What Part of the Brain Controls Emotions? https://youtu.be/UHTm2aqv-tQ small intestine https://youtu.be/7hweT7wgyF0 copyright by Dandelion Team
