Answer: Valves in the veins
Explanation: The flow of the blood inside the body takes place through the veins and arteries. The oxygenated blood from the heart is supplied to the different parts of the body.
The blood flows from the capillaries to the venules and from there to the veins. The blood moves in the veins by the rhythmic movement of the smooth muscles in the body.
Most of the blood moves against the gravity so there is a chance that it can backflow so to prevent this there are valves in the veins known as one way valves.
<u>Answer</u>:
C) They invade the body and can cause a humoral immune response.
This best explains the impact that pathogens in the environment might have on one's body.
<u>Explanation</u>:
Pathogens are the microorganisms that are found in the environment and have the tendency to cause diseases. The human body has various lines of defenses against the incoming pathogens, the Nonspecific responses keep the pathogens outside the body and these responses are common for all pathogens. If a pathogen manages to enter the body, then a series of specific responses are triggered which are focused on the type of pathogen.
The humoral response is a category of specific immunity and involves the substances found in body fluids. It particularly targets the newly invading pathogens. Hence, option C correctly describes the impact of pathogens on the body.
