This organ churns food and starts the digestion of proteins using pepsin and hydrochloric acid.
Stomach
The study of body structures?
Anatomy
This flap of cartilage prevents food from entering the trachea.
The epiglottis
This organ pumps blood throughout the body
<3
This type of digestion involves enzymes breaking down food molecules
chemical digestion
These structures in the small intestine increase surface area for absorption.
villi and microvilli
The correct sequence of biological organization from smallest to largest
cell → tissue → organ → organ system → organism?
Tiny sacs where gas exchange occurs
alveoli
The protein that carries oxygen is called

These tubes branch off from the trachea into the lungs
the bronchi
The route blood takes to become oxygenated and circulate back to the body
heart → lungs → heart → body
These two systems work together during gas exchange
respiratory and circulatory
The wave-like muscular contractions that push food through the digestive tract
Peristalsis
These are the four main tissue types in animals
epithelial, connective, muscle, and nervous tissues
The process by which gases move across alveolar membranes
diffusion
The blood components that help with clotting
