Human physiology is the study of how the human body functions, focusing on how organs work together to maintain life. The human body is organized hierarchically from cells to tissues to organs to organ systems. Major organ systems include the digestive system (food breakdown), respiratory system (gas exchange through lungs and diaphragm), circulatory system (blood transport via heart and blood vessels), nervous system (control and coordination through brain and nerves), muscular system (movement), skeletal system (support), excretory system (waste removal through kidneys), endocrine system (chemical control via hormones), and immune system (protection). Each system performs specific functions essential for survival, working in coordinated integration to maintain homeostasis.

Lymphatic system.
Integmentary system organization but that is deleted topics.
Okay.
Okay.
Almost complete.
Make your concepts clear. Okay. Concepts clear.
Concepts clear.
Concepts clear.
concept.
So biology concept read once. Yes.
for meology and concept.
So for anything related to biology you can approach me. Thank you. Okay.
So that's it. Anything?
Anything else?
foreign.
Okay. So, thank you. Bye.
Thank you, dears. Bye.
Bye. Take care. Good night.
