Ch#14 | Lec #21 | VERTEBRATE BLOOD CIRCULATORY SYSTEM(Heart Of Reptiles)(FSc Bio part 1)@riffatjahan
Heart of Reptiles: The heart of reptiles and all other amniotes function almost as four chambered heart. There are two auricles in the heart of reptiles. The reptiles have incompletely partitioned ventricle with the exception of crocodiles. In crocodiles the interventricular septum is complete and heart is four chambered. In all reptiles the left and right systemic arches carry oxygenated blood and arise from a region of ventricle called cavum venosum into which left ventricle directs its blood. The deoxygenated blood from the right atrium is directed towards the entrance of the pulmonary trunk, which is located on right side of ventricle. The two system arches start from the ventricle se...

Mam I was just asked about the swelling of spleen is it dangerous or not?
Yes It Is very dangerous because....An enlarged spleen can reduce the number of healthy red blood cells, platelets and white cells in your bloodstream, leading to more frequent infections. Anemia and increased bleeding also are possible.
❤❤
Mam how dangerous is the swelling of spleen?
Of course Yes It is very dangerous

See, You know I have started1st Year Biology only after that I will start 2nd Year Biology...
I can't disturb my sequence but the happy thing for you is that I am teaching last chapter, After that I will definitely start 2nd year Biology
I hope you will understand my side too... But I will try for you to finish this chapter quickly and start new Book Soon...

Soo the bullet proof jacket cannot be used again??
I wouldn't call it useless, but it's going to be seriously damaged and needing replacement. And this can also depends on several factors, such as the bullet that hit the armor, the speed of the bullet when it hits the armor, the type of armor, and the angle at which the bullets hit.
That's a new thing❤
Jazak Allah ... Stay Connected

Teacher you should teach us by white board and physical appearance bcz lecture dekhta. Hua banda bor nhi hota ... 😊
Your point is fine, I agree with you, But my point was everyone is teaching on the white board ... I thought that there should be something unique so i had this in my mind...
I also thought that there should be more focus on paper presentation...Because we should know that how to attempt paper with perfect headings...
For me I think Every one is teaching on the white board and the person gets bored... That's why I choose this notes pattern to make it unique and useful for the paper attempting point of view...
But at your request may be in future I will use it...
Mam what is OCD?
Obsessive-compulsive disorder (OCD) is a long-lasting disorder in which a person experiences uncontrollable and recurring thoughts (obsessions), engages in repetitive behaviors (compulsions), or both. People with OCD have time-consuming symptoms that can cause significant distress or interfere with daily life.
Common Symptoms Of OCD include: 1. Fear of germs or contamination 2. Fear of forgetting, losing, or misplacing something 3. Fear of losing control over one’s behavior 4. Aggressive thoughts toward others or oneself 5. Unwanted, forbidden, or taboo thoughts involving sex, religion, or harm 6. Desire to have things symmetrical or in perfect order
What is OCD mam?

W. Salam teacher g Teacher g nutrition ko simple words mein kiya kahein gay
Nutrition ko simple word mn Gazaeyat kahty han... or Its Simple definition Is.... (The process of providing or obtaining the food necessary for health and growth)
What is schizophrenia mam?
Basically it is a chronic brain disorder and their symptoms includes delusions, hallucination, disorganized speech, trouble with thinking and lack of motivation ..... But this disorder effects less than one percent of the U.S population.
It may be due to the imbalance of some chemicals like Dopamine and Serotonin in our brain... And this disorder appears in the age of 15 to 25 .
Antipsychotics are used in the treatment these are the medicine use to maintain the level of Dopamine or Serotonin. I think this detail will be enough about this disease.
@@riffatjahanWhy US population mam?
