That would be the left ventricle. It's thicker than the right ventricle because it pumps blood all over the body as opposed to the right ventricle which only pumps blood to the lungs.
The left ventricle, it works the hardest and needs the most muscle mass.
endocardium
The fox has a 4 chambered heart.
The left atrium is the chamber that receives oxygenated blood returning from the lungs.
atrium
coronary sinus
septum
hi bye you little turd
The left ventricle is the largest chamber in the heart. It is responsible for pumping oxygenated blood to the rest of the body and has thicker muscular walls compared to the other chambers to withstand the pressure needed for systemic circulation.
The left ventricle, it works the hardest and needs the most muscle mass.
There is no such thing as a fiber chamber of the heart.
The muscle walls of the heart are called the myocardium. This thick, muscular layer is responsible for the heart's contraction and pumping action. It is located between the inner layer, the endocardium, and the outer layer, the epicardium, which together form the heart's structure. The myocardium varies in thickness depending on the heart chamber, being most prominent in the ventricles.
The walls of the left ventricle are substantially thicker because it serves as the primary systemic pump of the heart. This chamber is responsible for pumping oxygenated blood to the entire body, requiring greater force and pressure. The increased muscle mass allows the left ventricle to generate the necessary strength to overcome the systemic vascular resistance. In contrast, the right ventricle, which pumps blood to the lungs, has thinner walls due to lower pressure requirements.
Pericardium: visceral- lining organ, parietal-= cavity lining Epicardium- surface if the heart Myocardium- muscle wall, cardiac muscle Endocardium- inner lining- chamber walls
The right atrium contains pectinate muscles in its walls. These muscular ridges are also present in the right auricle, which is an extension of the right atrium. Pectinate muscles help increase the surface area of the atrial wall and assist in the contraction of the heart.
