Hi, I am Doctor Ayda Basgul Martin. Welcome to my channel! In this video, we
will talk about ten major organs and their functions. You will able to locate
and identify them on different anatomical models after this video. If

free to comment below. The very first organ I would like to talk about is skin
which shown on the photo with the black arrow. The skin is the largest organ of
the body by weight. it belongs to the integumentary system.
The skin is an organ for the integumentary system. Its main function is to act as a
barrier to protect the body from the outside world.
It houses sensory receptors, exocrine glands and a muscle called arrector pili muscle
which causes goosebumps. It also functions to retain the body fluids,
excrete waste and regulate body temperature and have activation of
vitamin D. The heart is the most important organ of the circulatory and
another word maybe most correctly the cardiovascular system. The heart pumps
blood and distribute oxygen, nutrition, hormones, proteins to the tissues. Human
heart has four cavities to atria on the top and two ventricles, larger
cavities in the bottom. Fish has two chambers, reptiles and except crocodile
have a three-chambered heart. Only birds and mammals have four-chambered
heart. The lungs are the major organs of the respiratory system. You may see the
lung labeled as "R" for right and "L" for left lung and pointed out with red
circle on the torso model. The right lung is shorter than the left due to sparing
space for live, located just right below it.
Humans have three lobes in their right lung and two lobes in their left. The
main function of the lungs is the process of gas exchange and also has a
role regulating the body's acid-base balance. The liver is an organ of the
digestive system and it is the largest internal organ in the body. It pointed
out with yellow arrow on the torso model and located majority of it on right
upper quadrant, right below the diaphragm. It filters the blood coming from the
digestive tract before passing it to the rest of the body. The liver also
detoxifies chemicals and metabolize drugs regulate most chemical levels in
the blood and produced bile. Human liver has four lobes, the cats and dogs has six
lobes in their liver. The kidneys are the most important organs of the urinary
system. It's shown on the torso model and right kidney labeled with R and left one
with L. Kidneys are paired, bean-shaped organs. They filter blood and form the
urine, maintain fluid electrolyte and acid-base balance,
remove the waste products, produce hormones called renin and erythropoietin.
Kidneys are retroperitoneal organs means they are behind the protection of
peritoneum.
The thyroid gland is one of the major organs or glands of the endocrine system. it
plays a major role in metabolism, the growth and development of the human body.
It produces hormones called T3, T4 and Calcitonin. The spleen is the largest organ
of the lymphatic system. It filters the blood, as part of the immune system,
recycles the old red blood cells and stores Platelets and white blood
cells. The spleen also helps fight encapsulated bacteria that cause
pneumonia and meningitis. The small intestine is the part of the intestines
where 90% of the digestion and absorption of food occurs. The small
intestine is part of the digestive system. it has three portions; duodenum,
jejunum and ileum. Have you liked this video? Make sure to click to like, share
