The Body Systems of a Fruit Bat
By: Alyssa Forte
Skeletal and Muscular System
Bat bones seem to be lighter and slender and some bones are reduced. Bats also have created cranial bones for additional lightness. The wing is supported by the bones of the arm and one of the fingers. A bat's wing membrane is supported by the arm and by four highly elongated fingers. The lightness of the bones allow the wings to move in the air as the bat is flying. Bats have the fastest mammal muscle. The superfast muscles in bats occur in the throat and enable a crucial hunting behavior, which is echolocation; the bat sends out sound waves and listens for echoes bouncing off prey. The muscles allow the fruit bat to move by having strong wings and being able to increase speed with the amount of muscle the fruit bat has.
Fruit bats have the fives senses human doe; taste, touch, hear, smell, and vision. They use the five senses for locating food items, identifying roost sites and other bats, including family member or a prey of some sort. Fruit bats have excellent hearing, but if the ears are blocked, then they cannot maneuver. The brain of the bat carries out functions in a split, giving them ability to picture their surroundings quickly. Fruit bats have great vision to help capture light, but usually bats are blind and use their senses to function, but the fruit bats have all five senses.
Fruit bats are also considered to have a sixth sense, unlike humans. Bats use the echoes of their calls to locate obstacle, echolocation, to describe this sensory ability. This shows that bats see with their ears when their face is covered or unable to view.
In a fruit bat, they have lungs and that allow them to breathe, the exchange of air. The respiratory system of a bat has lungs that enable it to bring in oxygen and gets rid of carbon dioxide waste. They also have a diaphragm that contracts and the rib cage rises, pressure is created in the chest cavity, causing the lungs to expand and air to be let in. They also have a trachea to direct the air into the lungs.
Digestive and Excretory sytem
In a fruit bat, the digestive system is strong and fast and allows the bat to eat non-stop and that food consumes 5% of the body fat. Fruit bats also have mouths, like humans, to help digest the food that they eat like fruit or leaves. The saliva helps with softening the food, but the tongue is strong for crushing fruit and squeezing the juice out. Then it goes to the stomach to the small intestine which has villi to absorb nutrients and water required. And then it goes to the large intestine and does not prepare a lot of faeces because there are enough. The digestion takes about 12-34 minutes long!
The functions of the excretory system are to remove toxins and wastes from body, regulate water/fluids and salts in the body, and maintains pH of blood. The most important structure of the excretory system is Nephron because it contains capillaries and where filtering occurs. The kidneys are a part of the excretory system and they filter out wastes, water, and salt from blood.
In the female reproduction system, they have eggs, which are produced in the ovaries. The egg travels to oviduct (connects to uterus). In the female there is the cervix and it's the narrow opening of the uterus into the vagina, which leads to the outside of the body. Estrogen and progesterone are steroid hormones made by ovaries and estrogen causes secondary sex characteristics: breasts, wider hips, body fat, and menstruation.
For bats the reproduction of them occur during the spring time because it has the warmest temperature and food is not hard to find.
