పాఠం— Lesson
Human Body (మానవ శరీరం)
— most complex machine universe; 37 trillion cells; ~80 organs; 11 organ systems. (1) Skeletal — 206 bones adult (300 baby; some fuse); skull-spine-ribs-pelvis-limbs; provides shape + protection + bone marrow makes blood. (2) Muscular — 600+ muscles; voluntary (skeletal) + involuntary (smooth); cardiac (heart). (3) Circulatory/Cardiovascular — heart 100,000 beats/day; pumps 5L blood through 96,000 km blood vessels; arteries red oxygenated, veins blue deoxygenated, capillaries microscopic. (4) Respiratory — lungs ~6L capacity; trachea-bronchi-alveoli; 300 million alveoli; gas exchange O2 in CO2 out; 12-20 breaths/min. (5) Digestive — 9m long tract mouth-esophagus-stomach-small intestine-large intestine-rectum; digestion 24-72 hours; absorbs nutrients; bacteria gut microbiome 100 trillion! (6) Nervous — brain 86 billion neurons; spinal cord; nerves; controls everything; uses 20% body energy; brain weighs 1.4 kg. (7) Endocrine — hormones via glands; pituitary, thyroid, pancreas (insulin), adrenal, gonads. (8) Excretory/Urinary — kidneys 2 (each 150g) filter 180L blood/day; produce 1.5L urine; bladder. (9) Integumentary — skin largest organ 16% body weight; epidermis-dermis-subcutaneous; 30,000 dead skin cells shed/min = 1 lakh cells per day! (10) Lymphatic/Immune — fights infections; lymph nodes; T-cells; spleen; white blood cells. (11) Reproductive — male + female systems. Vital stats: height + weight chart age; BMI; daily 8 hours sleep (kids 9-11); 2L water. Heart — size of fist; beats 2.5 billion times life-time; 6 chambers actually 4 (2 atria + 2 ventricles); pumps 2000 gallons daily. Brain facts: thoughts travel 268 mph; brain pain-free (no pain receptors); learns lifelong neuroplasticity. 5 Senses + 6th vestibular (balance). Telugu Ayurveda 3 doshas: vata-pitta-kapha imbalance causes disease. Modern: AIIMS, Apollo, NIMS Hyderabad — top hospitals; Ayushman Bharat govt healthcare scheme.
