The correct answer is: B. Nervous
Cobra venom is a complex mixture of proteins, enzymes, and other substances that can cause a variety of symptoms, including paralysis, respiratory failure, and death. The venom is delivered through the cobra’s fangs, which are hollow and connected to venom glands. When the cobra bites, it injects venom into the victim’s bloodstream. The venom then travels to the nervous system, where it can cause paralysis. Paralysis can affect the muscles that control breathing, which can lead to respiratory failure and death.
The other options are incorrect because they are not the primary systems affected by cobra venom. The
digestive system is responsible for breaking down food and absorbing nutrients. The excretory system is responsible for removing waste products from the body. The circulatory system is responsible for transporting blood throughout the body.Cobra venom can also affect other systems in the body, such as the cardiovascular system, the endocrine system, and the immune system. However, the nervous system is the primary system affected by cobra venom.
