A) The functions of the skeletal system are:

Here are the answers to question 2:

a) The functions of the skeletal system are:

• Support: Provides a framework for the body and supports soft tissues.
• Protection: Protects internal organs (e.g., skull protects the brain, rib cage protects the heart and lungs).
• Movement: Serves as attachment points for muscles, allowing for locomotion and movement of body parts.
• Mineral Storage: Stores minerals, primarily calcium and phosphate, which can be released into the bloodstream as needed.
• Blood Cell Formation (Hematopoiesis): Red bone marrow produces red blood cells, white blood cells, and platelets.
• Fat Storage: Yellow bone marrow stores triglycerides as a source of energy.

b) The different bones of the Upper Limb (UL) are:

• Pectoral Girdle: Clavicle, Scapula
• Arm: Humerus
• Forearm: Radius, Ulna
• Wrist (Carpals): Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate
• Hand (Metacarpals): Five metacarpal bones
• Fingers (Phalanges): Fourteen phalanges (proximal, middle, and distal for digits 2-5; proximal and distal for digit 1/thumb)

c) The components of the cardiovascular system are:

• Heart: Pumps blood throughout the body.
• Blood Vessels: A network of tubes that transport blood, including arteries, arterioles, capillaries, venules, and veins.
• Blood: The fluid connective tissue that circulates, carrying oxygen, nutrients, hormones, and waste products.
