Which of these is the human body's first line of defense against invading pathogens such as bacteria and viruses?
skin and mucous membranes
What is responsible for defending blood against the pathogens?
White blood cells ingest the pathogens to prevent them from harming the human body
What is the main line of defense?
The main line of defense in the human body is the immune system, which helps to protect against pathogens such as bacteria, viruses, and parasites. This includes physical barriers like the skin, as well as specialized cells and proteins that work together to identify and neutralize harmful invaders.
The humans body's defense against disease is directly related to?
The human body's defense against disease is directly related to the immune system. The immune system is responsible for protecting the body from harmful pathogens such as bacteria, viruses, and other foreign substances. It does this by identifying and destroying these invaders to help keep the body healthy.
What two lines of defense does human skin have?
Human skin has two lines of defense: the physical barrier consisting of multiple layers of cells that prevent pathogens from entering the body, and the immune system, which includes immune cells that can attack and destroy any pathogens that manage to penetrate the skin.
How is hair a nonspecific defense for the human body?
it helps keep out a different variety of pathogens
Compare the features shared by an amoeba and a specialized cell in the human defense system?
Both amoebas and specialized cells in the human defense system (such as macrophages) are capable of phagocytosis, the process of engulfing and destroying foreign particles. They also both have the ability to move and change shape in order to reach their target. Additionally, they both play a key role in the body's immune response and defense against pathogens.
What is the first line of cellular defense against pathogens?
There are several ways to interpret the question. For some, the first line of defence is the skin since it acts as an impermeable barrier and also has antibacterial properties due to the acids secreted and normal bacteria fauna on the skin. However, since most pathogens, being capable of causing disease, can inherently overcome the skin defense, the first line of immune defence is the innate immune system that exists in the tissues underlying epithelia (skin or any mucous membranes). The innate immune system has cells that can recognize and destroy pathogens without specificity.
How can the human body prevent attack against pathogens?
Primary responseSkin, mucous and saliva entraps the pathogens and digests it.Secondary responsethe blood cells named "lymphocytes" will encounter the pathogens by releasing antibodies against to it.
What is the immune system called?
The immune system is used to prevent and destroy infection from various pathogens in the body. It consists of the circulatory system, lymphatic system, bone marrow, spleen and thymus gland.The first line of defense is against all foreign invaders.It is what is responsible for keeping you healthy. The human immune system is very complex, and has multiple components that all need to work in harmony for optimized function.
What is meant by HIV?
human immunodeficiency virus. it is a disease that severely weakens one's immune system, or defense against disease, over time.
The body's first line of defense against the invasion of disease-causing microorganisms is?
The body's first line of defense against disease-causing microorganisms is the skin, which acts as a physical barrier to prevent pathogens from entering the body. Additionally, mucous membranes in the respiratory and digestive tracts trap and expel pathogens. These barriers help prevent infections from establishing within the body.
