you may have read about alkaline diets that claim that you need to only eat alkaline foods in order to remain healthy according

hram777 [196]

Answer:

Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.

Explanation:

When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.

On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.

Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.

What is the single most critical defense system of your body? 2. how do mucous membranes provide protection from invading organi

eduard

Answer 1:

The most critical defense system of our body is known as immune system.

Discovery

More than 2000 years ago, the Greek historian Thucydides observed that occasionally some-one contact a disease, recovers and never catches the disease again, the person has become immune to the subsequent infection. In 1796 an English country doctor Edward Jenner hypothesized that cowpox somehow conferred protection against smallpox.

Components of immune system

Immune system is composed of three line of defense, these are:

1. First line of defense

It is non-specific defense and consist of skin, mucus and cilia.

2. Second line of defense

It is also non-specific defense includes macrophages, neutrophils, natural killer cells and complement system etc.

3. Third line of defense

It is specific defense and accomplished by B-cells and T-cells though cell mediated immunity and humoral mediated immunity.

Answer 2.

First line of defense include mucus membrane and skin. It is non-specific defense. it provide protection through the following ways:

Role of mucus membrane

1. Mucus membrane cover the digestive and respiratory tract and acts as a barrier to microbial invasion.

2. Mucus membrane line the inside of the nose to trap particles before they enter the body.

3. Mucus add moisture to each breath to prevent he airways and lungs from becoming dry and damaged. As air passes through the nasal cavity, moisture is transferred from the mucus secreted by the lining of the nasal cavity into the air.

4. Inside lungs a thin coat of mucus membrane is present inside alveoli which catches the dust and bacteria and swept them towards wind pipe through beating of cilia.

Answer 3:

Definition

The ability to resist damage from foreign substances such as microorganisms and harmful chemicals is known as immunity.

Explanation

Immunology is the study of immunity and the defense mechanism of the body. Immunity is one of the most important job provided to body in a number of ways, like in the form of anti-bodies, WBC, interferons etc.

Types of immunity

Immunity may be active or passive both types are achieved naturally or artificially.
