The temperature needed for the sperms to survive and thrive is lower than the optimum body temperature , hence it is not possible to maintain a lower temperature inside the body hence the testes are located outside the body.

∙ 12y agobecause the testes need to be at an adiquite temperature so the scrotum will pull the balls closer the body for haet and drop down for a cool down that's why its better to wear boxers than briefs. there is alot more to it but that's to put it "brief"

∙ 13y agoThey need to be kept at a lower temp than the rest of the body in order to produce the stuff that they produce.

∙ 13y agoThe testes are not contained in a body cavity (they are NOT 'outside the body'!) to keep them cool. Overheating the testes can cause impotence.

∙ 9y agoIn males, the testes remain outside the body cavity because it is the optimum temperature for them.

When removing an ovary what body cavity must open?
ventral cavity
Do you in hale or exhale when the volume of the chest cavity increases?
The air pressure in your chest cavity increases when you are exhaling. For air to leave your lungs, it must be at a higher pressure than the air outside. Your diaphragm pushes up against your chest cavity causing the space in your lungs to get smaller. If the volume decreases, the pressure has to rise. Don't believe me? start exhaling, then close your mouth. Your cheeks will puff out because the pressure inside is greater than the pressure outside.
How should a proper hypothesis be written?
If ... then... ex. if it is raining outside then it is wet outside.
Why do you have immunologically privileged sites?
Privileged sites include the uterus, testes and anterior chamber of the eye. Immune tolerance is developed "before" puberty. Sperm develop in the testes during puberty and become immunogenic. A fetus develops in the uterus after puberty as well. They must be protected from the adaptive immune system in order to survive.
If a 20 amp receptacle mounted outside must be?
Enclosed in a weather proof box and have a hinged weatherproof cover.
Why are testes housed outside the body?
Testes are housed outside the body in the scrotum because sperm production requires a slightly lower temperature than the rest of the body. By being outside, the testes can remain a few degrees cooler, which is necessary for optimal sperm production and function.
How do you get ascites?
typically liver failure. which leads to an obstruction of the portal vein. the fluid must go somewhere & the abdominal cavity is convient. talk to your md. ascites isn't trivial.
When removing an ovary what body cavity must open?
ventral cavity
Why are the female reproductive organs on the inside?
To protect them and the baby.Men's would also be better protected on the inside, but the testes must be outside for cooling, as the production of sperm is faster at slightly below body temperature.
Describe how the diaphragm and rib cage function in moving air out of a mammal's lungs?
The thoracic cavity (the chamber that holds the lungs and heart) is separated from the abdominal cavity by a muscular sheet, the diaphragm. When relaxed, the diaphragm bows into the thoracic cavity, decreases the volume of the cavity, and with contraction of abdominal muscles forces air out of the lungs; when the muscles of the diaphragm contract, it becomes taut and flat, increasing the volume and lowering the pressure of this cavity, drawing air into the lungs. To support their high energy demands for oxygen, mammals must be able to breathe while they suckle, chew food, or clutch prey in their jaws. This capacity is provided by the secondary palate, a shelf of bone forming the roof of the mouth, which separates the mouth from the nasal passages. sex
Name the branches of facial nerve?
Facial nerve is the 7th cranial nerve. It has an Intracranial and extracranial course. So branches must be named accordingly as: Branches in the cranial cavity Branches outside the cranial cavity I will post the answer after 2 days...till then the reader can ponder on the question
When abdominal effusion is suspected what adjustment must be made for a small-animal abdominal?
kVp should be increased by 15%
What is the temperature required for sperm production?
The sperm count is dependent on the temperature of the testes. The testes are external to the body because they require a lower temperature to produce viable sperm. The testes work best at temperatures slightly less than core body temperature. Spermatogenesis is less efficient at lower and higher temperatures. This is the reason for retraction of the testes in the cold as well as non-viable sperm in men with (medically) undescended testes.
When abdominal effusion is susected what adjustment must be made for a small-animal abdominal radiograph?
kVp should be increased by 15%
What would be the likely outcome if the testes remained undesceded?
1) In order for the male testes to produce sperm, the testes must descend out of the body and hang in the scrotum.2) Also, I have heard it said that a male should NOT use a laptop computer with his legs crossed, because that would heat up the testes and kill the sperm.

Could you get cavities in fake teeth?
No. To have a cavity, you must have a REAL tooth.
