Splet05. okt. 2024 · Warm blood approaching the testis comes close to the vessels carrying cool blood leaving the testis, so that the blood approaching the testis is cooled; the vessels form an intricate vascular network (pampiniform plexus) within the spermatic cord. Air in the sacs may help regulate the temperature of the testes. What happens if you heat up sperm?
SpletSo, the warmer blood leaving the heart through the arteries warms the cooler blood entering the heart through the veins. In contrast to birds and mammals, lizards, frogs, snakes, and other cold-blooded animals do not need insulation—it would only slow down heat transfer into their bodies.
