What else can I help you with?
What is the squeezing of white blood cells from capillaries to the body tissues called?
The squeezing of white blood cells from capillaries into body tissues is called diapedesis or extravasation. This process allows white blood cells to move out of the bloodstream and into tissues where they can respond to infection or injury. It is an essential part of the immune response, facilitating the delivery of immune cells to areas where they are needed.
When does idney infection occur?
Kidney infection, also called pyelonephritis and upper urinary tract infection, occurs when microbes, usually bacteria, invade the tissues of the kidney and multiply.
What does it mean when you press on your ankles and an indention is left?
That is called Edema, an accumulation of fluid in the tissues and cells. Below is a link to Ankle swelling.
Hormones affect specific tissues called?
Hormones affect specific tissues called target tissues or target cells. These tissues have receptors that bind to hormones, triggering a response or change in cellular activity.
What is a projection on a skull called?
If you have a projection on your skull, something that might relate is a swelling of the tissues of the skull due to a blow from a dull object. The projection on the Occipital Bone is called the Inion.
What is a set of nonspecific responses that often occurs in the body called?
Non-specific responses that occur in the body are often referred to as inflammation. This process involves the body's immune response to injury or infection, leading to symptoms such as redness, swelling, heat, and pain. Inflammation is a crucial part of the body's defense mechanism against harmful stimuli.
The process of entrance and growth of a microorganism or virus in the host is called?
The process of entrance and growth of a microorganism or virus in the host is called infection. Infection occurs when the pathogen gains access to the host's tissues, replicates or multiplies within the host, and causes disease symptoms.
When the body recognizes a relatively harmless substance as a dangerous antigen and mounts an immune response this response is called what?
This response is called an allergic reaction or hypersensitivity reaction. It can lead to symptoms such as skin rash, itching, swelling, or even more severe reactions like anaphylaxis.
Which lymphoid organs is a part of collection of tissues called the mucosa-associated lymphoid tissues MALT and removes pathogens entering the pharynx throat?
The tonsils are part of the mucosa-associated lymphoid tissues (MALT) and help remove pathogens that enter the pharynx (throat). They play a role in the immune response to protect the body from infection in the respiratory and digestive tracts.
What is the abnormal formation of fibrous tissue called?
The abnormal formation of fibrous tissue is called fibrosis. It can occur in response to injury, inflammation, or other types of damage to tissues. Fibrosis can lead to stiffening and scarring of tissues, affecting their function.
What type of blood vessel do the white blood corpuscles escape into the tissues at a wound?
White blood corpuscles, or leukocytes, escape into the tissues at a wound primarily through small blood vessels called capillaries. During the inflammatory response, the capillary walls become more permeable, allowing these immune cells to exit the bloodstream and migrate to the site of injury or infection to aid in healing and defense against pathogens.
How does a viral infection make you feel unwell?
A viral infection makes you feel unwell by triggering your immune system to respond to the invading virus. This response includes the release of chemicals called cytokines, which can cause inflammation, fever, fatigue, and muscle aches. Additionally, the virus itself can damage cells and tissues, leading to symptoms specific to the infection, such as coughing or gastrointestinal distress. Together, these factors contribute to the overall feeling of malaise associated with viral illnesses.
