Study Notes
Anatomy
- A plane is an imaginary flat surface that separates two portions of the body or an organ.
- There are different types of planes and sections, including:
- Frontal (coronal) section: separates the body into front and back portions from side to side.
- Longitudinal section: a plane along the long axis of an organ.
Circulatory System
- The function of the circulatory system is to transport oxygen and nutrients to tissues and remove waste products.
- The heart has four chambers:
- Right and left atria: receive blood from the body or lungs.
- Right and left ventricles: pump blood to the lungs or body, with thicker walls separated by the interventricular septum.
- Papillary muscles: columns of myocardium that project into the lower part of the right ventricle.
