Warfarin decreases the body’s ability to form blood clots by blocking the formation of vitamin K–dependent clotting factors. Vitamin K is needed to make clotting factors and prevent bleeding.
Tramadol, a centrally acting analgesic structurally related to codeine and morphine, consists of two enantiomers, both of which contribute to the analgesic activity via different mechanisms.
When reddit user JDMcompliant’s best friend asked him to babysit her cat, Jade, for a few days he happily obliged.
As a studio photographer, he also couldn’t help himself—and did a photoshoot for Jade and shared the session with the always cat-appreciate Internet.
JDCompliant said he used a simple setup: Strobe light; grey wall for backdrop; shot with a Canon 6D MK2, and 50mm prime lens (F8, 1/100). He said the biggest challenge was keeping Jade in focus since she was constantly moving. Anyway, enjoy!

The human heart is a muscular organ that pumps blood throughout the body. It is located in the center of the chest and is about the size of a fist. The heart is divided into four chambers: two atria and two ventricles. The atria receive blood from the body and the veins, and the ventricles pump blood out to the body and the arteries.
The chambers of the heart are separated by two septa: the interatrial septum and the interventricular septum. These septa prevent blood from mixing between the different chambers of the heart.
The heart also has four valves: the tricuspid valve, the mitral valve, the aortic valve, and the pulmonary valve. These valves open and close to control the flow of blood through the heart.
