The primary organs in your immune system is usually your heart and lungs. However, all of the different organs have different functions and without them, the body simply wouldn't survive. That being said, these "primary organs" can sometimes be dysfunctional in a person's body, affecting their body enormously. The logic therefore is that all organs are important as each other, seeing as they all make significant contributions to the overall health of the body and are equally vulnerable to harm, but the heart for example is responsible for keeping the body alive. It's like a motor, which is considered the most important part of a car, but how can a car move without any tyres? Of course, this answer can be criticised as a bit too Functionalist
The set of glands that regulate the activities of certain organs is called the endocrine system. The endocrine system releases chemical products into the bloodstream.
The term "immune system" is a misnomer because it does not just protect against external threats like pathogens, but also plays a role in maintaining tissue homeostasis, responding to stress, and influencing various physiological processes. It's a complex network of cells, tissues, and organs that goes beyond just immunity.
System.
Two or more organs working together are called an organ system.
If you are referring to the system of borrowing and unification: Virtually all of them. Only the very earliest cinema organs did not use this system - they were simply church style organs set up in a theater - not to imply that church organs do not use borrowing and unification but at the time the key action of organs had not developed enough to use this system.
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.
The body is affected and loses its ability to adapt to the situation and fatigue may set in
T cells's primary task is to activate B cells and killer T cells. The B cells searchfor antigens matching its receptors. If it finds such antigen it connects to it, and inside the B cell a triggering signal is set off.
When a person's weight falls below their body's set point, they may experience symptoms of malnutrition, such as fatigue, dizziness, weakened immune system, and hair loss. Their body may also slow down metabolism to conserve energy and protect vital organs.
The skeleto-muscular system is the set of organs including the bones, the skeletal muscles, and the associated tendons and ligaments. The cat's skeleton (the bones) are part of the skeleto-muscular system.
AIDS is a set of symptoms and infections resulting from the damage to the human immune system caused by HIV. The symptoms are: Highten risk of getting a tumour or cancer. The net median time survival time after infection with HIV is estimated to be 9 to 11 years. I would says AIDS is pretty bad.
the enitity which is set primary key is said to be strong entity and the entity which does not set primary key is said to be weak entity.
