The human heart is situated in the mediastinum, at the level of thoracic vertebrae T5 ... An adult heart has a mass of 250–350 grams (9–12 oz). [17]
However, even the benign tumors of the heart can be lethal due to either direct extension into the electrical conduction system of the heart (causing complete heart block or a fatal dysrhythmia), or due to emboli from the tumor mass that may have lethal sequelae. Prompt resection is indicated for myxomas due to the risk of embolization or ...
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The mass of the left ventricle, as estimated by magnetic resonance imaging, averages 143 g ± 38.4 g, with a range of 87–224 g. [2] The right ventricle is equal in size to the left ventricle [citation needed] and contains roughly 85 millilitres (3 imp fl oz; 3 US fl oz) in the adult.
Left ventricular mass or LVM refers to the mass of the left ventricle of the heart. Left ventricular mass index or LVMi is LVM divided by body surface area. LVM is usually estimated using linear measurements obtained from echocardiography, [1] but can also be calculated using CT or MRI images. [2]
The heart works by pumping blood around the body allowing oxygen, nutrients, waste, hormones and white blood cells to be transported. Diagram of the human heart. The heart is composed of two atria and two ventricles. The primary purpose of the atria is to allow uninterrupted venous blood flow to the heart during ventricular systole.

Human body weight is a person's mass or weight.. Strictly speaking, body weight is the measurement of mass without items located on the person. Practically though, body weight may be measured with clothes on, but without shoes or heavy accessories such as mobile phones and wallets, and using manual or digital weighing scales.
