@gethelpwithproctoredexam: The Human Heart is a muscular organ located in the chest between the lungs. It has four chambers: the right and left atria (upper chambers) and the right and left ventricles (lower chambers). The heart pumps blood throughout the body through arteries and veins. Valves such as the tricuspid, mitral, pulmonary, and aortic valves ensure one-way blood flow and prevent backflow during circulation. The Kidney is a bean-shaped organ located on both sides of the spine in the abdomen. Each kidney contains millions of nephrons, the functional units responsible for filtering blood. The kidney removes waste products, balances fluids and electrolytes, and produces urine, which flows through the ureters to the bladder for excretion. #anatomy #kidney #nursingstudent #student #fyp
