24 wrz 2020 · Single-cell and single-nucleus RNA sequencing are used to construct a cellular atlas of the human heart that will aid further research into cardiac physiology and disease.
17 sie 2023 · The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle.
Cardiovascular system anatomy and physiology. Normal heart sounds. Abnormal heart sounds. Lymphatic system anatomy and physiology. This Osmosis High-Yield Note provides an overview of Cardiovascular Anatomy and Physiology essentials.
12 wrz 2023 · Function. The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism. Oxygen is bound to molecules called haemoglobin that are on the surface of the red blood cells in the blood.
4 lip 2016 · The cells of the heart, like neurons, are excitable and generate action potentials. These action potentials initiate contraction and thus determine the heart rate. Disorders in electrical activity can induce serious and sometimes lethal disturbances in cardiac rhythm. In this section the electrical properties of cardiac cells are described.
Describe the structure of cardiac muscle. Identify and describe the components of the conducting system that distributes electrical impulses through the heart. Compare the effect of ion movement on membrane potential of cardiac conductive and contractile cells. Relate characteristics of an electrocardiogram to events in the cardiac cycle.
