Human Respiratory Process:
Respiration rate A normal person breathes between 12-20 times per minute, and the respiratory system delivers oxygen to the body through respiration, where the air pressure inside the lungs is less than the atmospheric pressure, so the air exits. Runs from In the lungs through the nose, when exhaling, the air pressure inside the lungs exceeds the atmospheric pressure, so air from the lungs exits the body, and the respiratory muscles control the process of breathing in and out. becomes.
Blood circulating in the human body
Red Blood Cells The adult human body is made up of 25 trillion red blood cells. ; Here’s a few basic facts about a stomp pad and how it is used.
Dear readers:
Red blood cells are spherical in shape and concave on both sides, facilitating their passage through narrow blood vessels. Delivering oxygen to various organs and tissues of the body. At the level of red blood cells are antigens, which play a role in determining blood type and their role in the immune system’s ability to identify foreign red blood cells and distinguish them from red blood cells. Provides help. Red blood cells contain hemoglobin, which contains iron, and this is what makes blood red. Blood vessels Arteries in the brain Are:

Are made up of cartilage. , And some are partly made up of cartilage. In human development, cartilage is slowly replaced by bone, with the help of calcium, and when a person reaches the age of 25, bone growth stops.
Dear readers:
In the light of medical science and in the light of biology, we have explained to you the wonders of the human body. There is no caste. Just try to know this honorable caste. The doors of knowledge and wisdom will open on you
