What is capillary telangiectasia?
Capillary telangiectasia is a rare condition where tiny dilated blood vessels (capillaries) are present in the brain or spinal cord. These abnormal blood vessels can cause neurological symptoms such as headaches, seizures, or weakness, and may increase the risk of bleeding in the affected area. Treatment options depend on the location and symptoms of the telangiectasia.
What is the gland signals the body to increase production of growth hormones that interact with the sex hormones to cause the growth spurt and puberty?
oestrogen and progesterone
An increase in breathing rate can be triggered by an increase in the?
An increase in breathing rate can be triggered by an increase in carbon dioxide levels in the blood, low oxygen levels, physical exertion, stress, or high altitude. These factors can stimulate the respiratory centers in the brain to increase the rate and depth of breathing to help maintain proper gas exchange in the body.
What factor would cause a mutation that would cause an allele frequency to increase?
An increase in allele frequency can occur due to factors such as genetic drift, gene flow from other populations, natural selection favoring that allele, or a genetic mutation that confers a selective advantage.
An increase in magnification causes?
The increase in magnification cause a decrease in the field of view.
Why does pollen cause pollen?
it contains histamines which work in the body to cause Allergies
What chemical cause blood vessels to constrict?
Two examples are histamines and amphetamines.
How do pulmonary agents cause pulmonary edema?
Pulmonary agents can cause pulmonary edema by disrupting the normal balance of fluid in the lungs, leading to fluid accumulation in the air sacs (alveoli) and interstitial spaces. This can result from mechanisms such as increased capillary permeability, inflammation, or increased hydrostatic pressure in the pulmonary circulation. Ultimately, this leads to impaired gas exchange and breathing difficulties.
Why do many allergy medicines contain antihistamines?
Histamines cause many of the standard allergic responses: itching, sneezing, runny nose, etc. Antihistamines block histamines from binding on their receptors in the body.
What are antimetics used for?
Histamines are produced in the body when the body perceives something as a foreign body. Allergens also cause the production of histamines and hence antihistamines are used in case of an allergic attack.
When ADH is produced what happens?
If there is too little water in the blood, the hypothalamus will detect this and more ADH (Anti-Diuretic Hormone) will be produced. The increase in ADH will cause an increase in the permeability of the collecting duct in the kidney and so more water is reabsorbed into the blood. :)
What happens if the permeability of a resting axon to sodium ion increases?
If the permeability of a resting axon to sodium ion increases, it would lead to depolarization of the neuron. This would cause sodium ions to enter the cell, making the inside more positive and potentially triggering an action potential.
How does Precipitation from into soil?
Precipitation infiltrates the soil through a combination of factors such as gravity, capillary action, and soil permeability. The water moves through the soil profile, distributing nutrients and minerals while recharging groundwater reserves. Excess water may cause runoff, leading to erosion and nutrient loss.

What is the function of the histamine?
Histamine is a chemical mediator. These are released by mammalian cells and effect their cells in their immediate vicinity. Histamines are released from white blood cells in the airways, they are released in response to injury or an allergen. They cause small arteries and arterioles to dilate and the permeability of capillaries to increase. They produce an inflammatory response where swelling, itching and redness occurs.Histamines are what causes allergic reactions in people. They can cause hives, itchy skin, runny or stuffy nose and watery eyes.
The release of histamines does not cause in the affected area?
When histamine is released into the body, it can cause swelling, itching, bronchi constriction, watery eyes, and a runny nose. It can lead to anaphylaxis in severe cases.
What is the role of vasodilation?
vasodilation is controlled by the nervous system as well as renal system and cardiovascular system.vasodilation cause increase heat production. and feel more warmthvasodilation cause blood pressure is low and client under go hypotensive state.vasodilation also affect the nervous system . it will produce synccope when suddenly vasodilationit cause increase capillary blood that affect the hair growth in alopecia case
