The reproductive system have one main agenda, to reproduce. But, Green Sea turtles reproduce very differently than humans. The Human reproductive system uses sperm and an egg to, most of the time, create one child. The reproduction happens internally and the child develops for about 40 weeks. The Green Sea turtle also uses internal fertilization to create the eggs. It can can store live sperm for several years. Then after it is fertilized, varying from a couple days to weeks, the female takes her eggs and lays them ashore onto a beach into the egg cavity. The female may deposit as many as 150 eggs. The eggs are soft- shelled so they will not break. These eggs develop in the sand for about 50 to 70 days. Then the babies hatch. Both the babies of the human and the turtle develop for a couple of weeks, but the human development takes much longer. The turtle also does have internal fertilization like a human but leaves its eggs to develop on a beach. The amount of babies are much higher for the Green Sea turtle as well. Both have similarities, but are very different also.
The skeletal system also varies between humans and the Green Sea turtle. Humans have endoskeletons, which means the skeleton is internal. Humans have 206 bones and they are all inside the body. The Green Sea turtle has an exoskeleton, which means its bones are on the outside of its body, and an endoskeleton. It has a shell, the top is called the carapace and the bottom is the plastron. The shell is made up of many little bones covered by horney scales, or scutes. The Green Sea turtle has ribs, a backbone, pectoral girdle and pelvic girdle that are joined to the inner layer of the exoskeleton. This shell is used for protection and the bones inside are for structure, like the human skeletal system Both species relate in some ways, but differ in others, like the addition of the exoskeleton.
The muscular system of the Humans helps with movement, digestion, involuntary action, eyc. There are three types of muscles: skeletal, cardiac, and smooth.The skeletal muscles help with bones, the cardiac muscle helps pump the heart and the smooth help organs. The Green sea turtle are alike and also have skeletal, smooth, and cardiac muscles. They have larger pectoral muscles which are used to swim, which are the skeletal muscles. The sea turtles’ heart has a total three cardiac muscle chambers, two are atria’s and one is a ventricle. The turtles organs are made of smooth muscles. This includes the lungs, stomach, etc. Both species have the same types of muscles, therefore are alike in this matter.
The human nervous system contains the brain, spinal cord, sensory organs, and nerves. The brain and the spinal cord are the central nervous system and the sensory organs and nerves are the peripheral nervous system. These are work together to control voluntary and involuntary body functions. The brain will send information down the spinal cord for neurons to deliver to the rest of the body. The Green Sea turtle also has the same nervous system. The brain is located in the skull. The spinal cord and nerves help deliver the messages sent from the brain through the body. They also perform voluntary and involuntary functions, as well.
The Circulatory system for humans is closed. It contains a heart, veins, arteries, and capillaries. The heart pumps blood, which carries oxygen, waste, and other materials, through the body using the blood vessels. These blood vessels include veins, arteries, and capillaries. The Green Sea turtles have closed- circulatory systems, also. The system consists of a heart, arteries, veins, and lymphatic vessels. The heart pumps the blood through the arteries which carry it away from the heart and the veins bring it back. The lymphatic vessels transport tissue fluid from outside of the system into it. Both species related but both were not exactly the same, there wire differences, like the lymphatic vessels.
The human respiratory system consists of lungs, trachea, nose, pharynx, larynx, and bronchi. Humans inhale xylem and exhale carbon dioxide. This process keeps the body healthy and alive. The green sea turtles respiratory system is much like the humans. They have lungs, bronchi, etc, like humans. But, they have a special adaptation of being able to use anaerobic respiration for long periods of time. This adaptation humans have not developed like the turtles have since they live in water. Humans can use aerobic respiration for a short amount of time but no where near as long as sea turtle.
The human digestive system contains the mouth, stomach, liver, esophagus, gall bladder, rectum, anus, long intestine, short intestine, and pancreas. In the mouth teeth chew up the food and saliva dissolves it, then it goes down the esophagus, the stomach and other organs to digest the food and take out the nutrients. The waste exits out the anus. The Green Sea turtle contains many of the same features in it’s digestive system. The mouth has no teeth so the jaws is strong enough to chew. Since the body cavity of the turtle is large, the intestines are large and bulky. There is also a special digestive tubes that contain bacterial symbionts, they help digest cellulose, which is found in plants. These reasons why the Green Sea turtles and humans are similar but different, also.
The human excretory system removes unnecessary, harmful, and excess material from the body. The excretory system contains the kidneys, large intestine, liver, skin, lungs, ureters, bladder, and urethra. This process helps the organism maintain homeostasis. The Green Sea turtles’ excretory system works the same way. The kidney filters the blood. Then urine is produced and it exits out the cloaca. But, there is a difference, the sea turtle has salt glands, humans have sweat glands. These salt glands help the kidney by taking out the extra salt from the water. The excretory system of both species relate, but also differ.
