The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
When a pathogen (disease-causing organism) invades the body, the neutrophils gather at the entry site and try to engulf it and destroy it.
A T helper cell will recognise only one pathogen. If the T helper cell recognises the invader, it will immediately clone to increase numbers.
After a few days of fighting off the pathogen, you will recover from your infection.

If a person is passed out due to alcohol overdose you need to perform the following steps :-
- Try to wake him up by pinching in the sternum or the ear lob hard enough so it causes pain
- If he still doesn't wake up ,tell another person to call 911
- Meanwhile , you should lean the person forward ,best if he is on the floor to eliminate the chances of falling
- Do not leave the person alone at any cost ,because there are chances of assault if the surroundings are not safe
- When the 911 arrives ,tell them all the details about all the activities and the drinks that were present

- Less physical activity
- Seizures
- Less than 8 breaths per minute
- Reduced body temperature

At first, a fetus cannot distinguish between different voices.
A fetus begins responding to sound at between 22 and 24 weeks but can only hear low frequencies, such as a dog barking or a lawn mower.
As the auditory system and the brain continue to develop, this range increases. By late pregnancy, the fetus can hear voices and distinguish between
so at 22 weeks they're in the middle of the second trimester and can hear sounds but in the 3rd trimester can distinguish between voices
