Study Notes

Endocrine System

Comprises glands that secrete hormones regulating growth, reproduction, and nutrient usage.
Key glands include:
- Pineal gland
- Pituitary gland
- Thyroid gland and parathyroid glands
- Thymus gland
- Adrenal glands
- Pancreas
- Ovaries (female)
- Testes (male)

Cardiovascular System

Consists of heart and blood vessels.
Heart is responsible for pumping blood; vessels transport blood to tissues.
Blood functions include transporting oxygen, carbon dioxide, nutrients, and hormones.
Contains white blood cells and chemicals that protect against infections.

Integumentary System

Forms the body’s external covering (skin) and includes hair and nails.
Provides waterproofing and protection for deeper tissues from injury.
Synthesizes vitamin D when exposed to sunlight.
Excretes salts through perspiration and helps regulate body temperature.
Houses cutaneous nerve receptors related to sensation.

Skeletal System

Composed of bones, cartilages, ligaments, and joints.
Serves as attachment points for muscles, facilitating movement.
Protects vital organs like the heart and lungs.
Site of blood cell production within bone marrow.
Functions as a mineral storage reserve.

Nervous System

Acts as the fastest control system in the body.
Responds to internal and external stimuli by activating appropriate muscles and glands.
Comprises components such as the brain, spinal cord, nerves, and sensory receptors.
