Units

UNIT 01
Body organization and homeostasis
The body is organized from cells to systems, and it constantly adjusts to keep internal conditions stable.
UNIT 02
Cells and tissues
Similar cells form tissues. There are only four tissue types, and every organ is built from them.
UNIT 03
Skeletal and muscular systems
Bones support and protect the body, and muscles pull on bones to move them.
UNIT 04
Nervous and endocrine systems
The nervous system sends fast electrical signals; the endocrine system sends slower chemical messages through the blood.
UNIT 05
Cardiovascular and respiratory systems
The heart pumps blood through vessels to deliver oxygen, and the lungs load blood with oxygen and remove carbon dioxide.
UNIT 06
Digestive, urinary and immune systems
The digestive system breaks food into nutrients, the kidneys filter blood, and the immune system defends against pathogens.
UNIT 07
Integumentary system
The skin is the body's largest organ: it protects, regulates temperature, senses the environment and makes vitamin D.
UNIT 08
Special senses
Specialized receptors in the eyes, ears, tongue and nose turn light, sound, motion and chemicals into nerve signals.
UNIT 09
Reproductive system and development
The reproductive systems produce gametes and hormones, and after fertilization the embryo develops with support from the placenta.
