The human skeleton of an adult consists of around 206 to 210 bones, depending on the counting of sternum (which may alternatively be included as the manubrium, body of sternum, and the xiphoid process). It is composed of 300 bones at birth, but later decreases to 80 bones in the axial skeleton and 126 bones in the appendicular skeleton.

2. The human body comprises 12 distinct human body systems, and their functions reflect their names: cardiovascular, digestive, endocrine, immune, integumentary, lymphatic, muscular, nervous, reproductive, respiratory, skeletal and urinary.

10. 24 to 72 hours

11. receives highest blood flow per gram of tissue. Heart. unlike other organs, the heart receives its blood supply during diastole. 90% of blood flow through coronaries is during diastole. as the heart rate increases, the amount of time spent in diastole is relatively decreased.In terns of blood flow per 100gm of tissue, the organ with the greatest amount of blood flow is the carotid body in the next at the junction of the common carrots and its branches the internal and external carotids. It receives around 2 litres of blood per 100 gm.

12. Pink

13.The human body has more than 600 muscles.
