Up until a 1962 demonstration of tuberculosis airborne transmission, airborne transmission of all major respiratory diseases was assumed to be of insignificant or moderate consequence over the following fifty years.

Before COVID-19, only a small number of diseases—those that were blatantly spread to people not in the same room—were generally acknowledged as airborne. This is because the contact/droplet paradigm remained popular.

<h3>What does the term "airborne transmission" mean?</h3>
  • The term "airborne transmission" refers to the propagation of droplet nuclei (aerosols) that retain their infectious properties after being suspended in air for a lengthy period of time and over great distances.
  • Bacteria or viruses that cause airborne infections are most frequently spread by tiny respiratory droplets. When a person with the airborne sickness sneezes, coughs, laughs, or exhales in any other way, these droplets are released.

puteri [66]
One big reason for this is because individuals of the same species often have to fight over shared resources (this means shared food and shared environment).

Because they fight over a limited amount of space and food, competition between individuals within one species can be present and very tough.

On the other hand, having members of different species also possibly means different territories and different food sources. A lion has no quarrel with dolphins, while it can have a lot of fights with lions from different prides (large group of lions).

Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a per
olganol [36]

Blood distribution is adjusted by a short-term neural control mechanism to meet specific demands. During working out, the hypothalamus signals for reduced vasomotor stimulation of the skin vessels. Blood moves into the capillary veins, and heat radiates from the skin to reduce body temperature.

<h3>Veins</h3>

All over your body, veins are blood vessels that collect blood with low oxygen content and send it back to your heart. Your circulatory system includes your veins. They cooperate with your heart, other blood vessels, and other organs to maintain blood flow. Most of your body's blood is stored in veins. Your veins actually contain around 75% of your blood. Veins have two basic functions. One function is to gather blood that is low in oxygen throughout your body and transport it back to your heart. The other function is to transport blood that is rich in oxygen from your lungs to your heart. Only during this process do veins transport oxygen-rich blood.

Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a person who is working out?
