the female immune system does recognize semen as a foreign body that's one of the reasons males produce so many sperm.
Immune system of female does recognizes semen but non selectively (First line of immune defence). That's why male discharge 100 million sperms per ml of semen (Generally, 3-4 ml semen per ejaculate). Only few hundreds of them could successfully go through hostile conditions of female reproductive tract, especially vagina. But as sperms approaches near ovum, they are recognized by fertilizing and antifertilizing mechanism to effect fertilization.
What else can I help you with?
Immune system recognize germs and reject them?
The immune system certainly does recognize germs and other foreign bodies. The immune system will then try to fight them off.
How are foreign particles removed from the body?
Foreign particles are primarily removed from the body through the immune system and various physiological mechanisms. The respiratory system uses cilia and mucus to trap and expel inhaled particles. In the gastrointestinal tract, foreign materials can be eliminated through digestion and excretion. Additionally, immune cells like macrophages and neutrophils identify and engulf foreign particles, facilitating their removal from tissues and the bloodstream.
The specific foreign substances that an individual s immune system has the ability to recognize and resist is determined by?
The specific foreign substances, or antigens, that an individual's immune system can recognize and resist are determined by their genetic makeup, particularly the genes encoding the major histocompatibility complex (MHC) and various receptors on immune cells. These genetic factors influence the diversity of immune responses. Additionally, exposure to pathogens throughout life shapes the immune system's memory and responsiveness, allowing it to recognize previously encountered antigens.
The specific foreign substances that an individuals immune system has the ability to recognize and resist is detemined by?
The immune system's ability to recognize and resist specific foreign substances is determined by the unique set of proteins on the surface of cells called major histocompatibility complex (MHC) molecules. MHC molecules present antigens to immune cells, which stimulate the immune response. The immune system can only respond to antigens that are recognized by MHC molecules.
How does phagoctosis work?
Phagocytosis is a process where specialized immune cells called phagocytes engulf and digest foreign particles, such as bacteria or debris, to protect the body from infection and maintain tissue health. Phagocytes recognize the foreign particles through specific receptors on their cell surface, engulf them into a vesicle called a phagosome, and then fuse this vesicle with lysosomes containing enzymes to break down the ingested material. The digested particles are then eliminated from the body.
How does autoimmune disease affect the body?
Normally, immune cells work to recognize and help destroy foreign invaders like bacteria, viruses, and fungi. In autoimmune disorders, these cells mistakenly recognize various tissues of the body as foreign invaders
Mobile immune system cells that engulf and digest bacteria and other microbes?
These immune cells are called phagocytes, such as macrophages and neutrophils. They recognize and engulf foreign particles through a process called phagocytosis, where the invader is enclosed in a vesicle and broken down by enzymes. This is a critical mechanism for removing pathogens and maintaining the body's defense against infections.
What are some ways microbes evade the body's immune system?
Microbes evade the immune system through inhibition of phagocytosis by affecting the receptors that phagocytes use to engulf bacteria or by mimicking host cells so that the immune system does not recognize them as foreign.
What kinds of cells wander the interstitial fluid eating whatever bacteria and virus-infected cells they encounter and recognize?
These are typically white blood cells referred to as macrophages. They are part of the body's immune system and play a key role in engulfing and destroying foreign particles, including bacteria and virus-infected cells. Macrophages can also present antigens to other immune cells to trigger an immune response.
Helps immune system recognize germs and reject them?
The immune system recognizes germs thanks to specialized cells and molecules that can identify the foreign invaders. Once identified, the immune system activates a response to eliminate the germs from the body. This recognition and rejection process is crucial for protecting the body against infections and maintaining overall health.
What are antiebodies?
a blood protein produced in responce to counteracting and specific antigen.antibodies combine chemically with substance that the body recognizes as allien,such as bacteria,viruses and foreign substances in the blood.
How does the body respond to foreign particles such as pollen in the body?
When foreign particles like pollen enter the body, the immune system recognizes them as potential threats. This triggers an immune response, including the release of histamines and other chemicals that cause inflammation, leading to symptoms such as sneezing, itching, and nasal congestion. In people with allergies, the immune system overreacts to these harmless particles, resulting in exaggerated responses. Additionally, antibodies called IgE are produced, which can sensitize the body to future exposures.
